Wireless Antennas 

The wireless antennas send out signals from wireless devices installed in US40a and receive signals 

sent from external devices. 

These antennas cannot be viewed from the outside of US40a. 

NOTE: Make the LCD panel of US40a remain opened. This can avoid 

any obstacles against the antennas before wireless connection is 

established. 

USB2.0 Ports 

IMPORTANT: The wireless devices installed in US40a are designed 

so that their frequencies may not exceed the limit of the exposure to the 

radio frequency recommended by the international guideline (ICNIRP). 

The SAR (specific absorption rate), the rate at which the radio 

frequency energy is absorbed into body issues, largely depends on the 

distance between the origin of radio frequency (antenna) and a human 

body. 

The wireless devices meet the international guideline about the 

exposure of radiated radio frequency only when the distance between 

the antenna and a human body is at least 2 to 3 cm. 

Three USB ports are located on US40a to allow peripherals conforming to the USB standard (e.g. 

printers and DVD drives) to be connected to US40a. 

IMPORTANT: The USB ports always supply 5VDC power to 

external USB devices connected to the ports while the system power is 

off. Accordingly, the USB devices can always be charged without the 

system power. In order to prevent the battery power from being 

discharged fully in the system power-off status, disconnect external 

USB devices from the USB ports if they are not used.


Express Card Slot 

Only by inserting a memory card or a simply replaceable device into this Express Card slot, you can 

add a hardware feature provided by a storage device, a wired or wireless communication card or a 

safety device to US40a. 

US40a can accept two types of Express Cards, or Express Card/34mm (width 34 mm) and Express 

Card/54 mm (width 54 mm and L shape). The connectors on Express Cards of both types have the 

same width (34 mm). 

Standard cards are 75 mm in length (shorter than that of CardBus by 10.6 mm) and 5 mm in 

thickness. Portions extended outward from the standard shape of the card due to an antenna or 

socket may be thicker than 5 mm. 

Inserting Express Card into Express Card Slot 

Insert an Express Card into the Express Card slot in the following steps: 

1. Align the Express Card to the connector so that the connector of the card faces the slot. 

The arrow or the label shows the top side of the Express Card. 

2. Slide the Express Card in the slot and press firmly until it is completely seated in its 

connector. 

3. The Express Card is automatically detected and a proper driver is installed. 

The system may request you to use the driver supplied by the manufacturer. If this occurs, 

insert the driver CD coming with the Express Card. 

To inform you of success in the installation, US40a beeps twice. 

Ejecting Express Card from Express Card Slot 

Press the Express Card to eject it from the Express Card slot. 

AC Power Port 

Connect the AC adapter coming with US40a to this AC power port to supply AC power. 

IMPORTANT: Be sure to use the AC adapter and the 2-pin power 

cord coming with US40a. Using another adapter and/or power cord 

may cause the system to be damaged even if they seem to be the same 

as the attached ones.


Use of Touch Pad 

Clicking/Double-clicking/Drugging 

Clicking 

Put the pointer on an icon or a folder and press the left click button once. 

If you press the right click button, you can select one of operations shown by the right button 

clicking. 

Double-clicking 

Put the pointer on an icon or a folder and press the left click button twice quickly. 

Drugging 

To drug an icon or a folder, put the pointer on the icon or the folder and move the finger on the pad 

with left click button pressed. 

NOTES: 

• Tapping the pad with the tip of a finger leads the same operation as 

clicking the mouse. Tapping the pad with the tip of a finger twice 

quickly brings the same operation as double-clicking the mouse. 

These actions are called "tap" and "double-tap", respectively. 

• Drugging also takes place if you tap the pad lightly with the pointer 

put on an icon or folder, make a finger contact with the pad and 

move the finger. 

Using Expansion Features of Touch Pad 

In addition to tapping and drugging on the pad only, you can use the useful expansion features as 

follows: 

• Slipping a finger on the pad to scroll the screen (defining an area with scroll feature on the 

pad). 

• Disabling the touch pad to avoid incorrect tapping and pointer moving during input on the 

keyboard. 

• Turning on/off the touch pad temporarily.


Wireless LAN Features 

The wireless LAN features allow computers separated from one another to share data and programs 

and transfer messages among them. 

Notes on Use of Wireless LAN 

• The transmission speed and distance of wireless LAN vary depending on the used 

wireless LAN devices, circumferential conditions including radio wave, obstacles and 

installation environments. 

• The transmission speed of wireless LAN tends to be slower with longer communication 

distance due to the nature of radio wave. For more comfortable usage of wireless LAN, it 

is recommended to place wireless LAN devices within short distance. 

• The transmission speed and distance of wireless LAN (IEEE802.11b or IEEE802.11g) 

supported devices may decrease while using a microwave oven near by. It is 

recommended to use wireless LAN (IEEE802.11b or IEEE802.11g) supported devices 

away from microwave oven. 

• When wireless LAN (IEEE802.11b or IEEE802.11g) supported devices and Bluetooth 

supported devices are used simultaneously, the transmission speed and distance of devices 

may decrease. In such cases it is recommended to switch off either of the wireless LAN 

(IEEE802.11b or IEEE802.11g) devices and the Bluetooth supported devices or use by 

keeping distance between them. 

• To connect US40a to a network, an optional wireless LAN access point is required. 

• Turn off the power of US40a or switch off the wireless LAN feature in an area where 

medical authorities prohibit usage of this product. Moreover, even in the medical 

establishment where usage of this product has been allowed, either turn off the power or 

switch off the wireless LAN of this product when medical equipments are being used in 

near by. 

• During network communication, do not enter US40a into the standby and suspend states. 

• Network communication shortens the period in which US40a can be driven by the battery 

only. When communication for a long period is required, connect the AC adapter to 

US40a to supply power through an AC outlet. 

• In standby or suspend mode the network feature is disabled temporarily. Therefore put 

US40a into standby or suspend modes after completion of communication operations like 

file copy etc. Moreover, some application software lost data while US40a recovers from 

standby or suspend mode. While using applications which uses network, verify the same 

with the system administrator and use the standby or suspend mode appropriately.


Notes on Security in Use of Wireless LAN Devices 

The wireless LAN can transfer data between a PC and a wireless access point through radio waves 

instead of using LAN cables. Accordingly, the wireless LAN is advantageous to enable free LAN 

connection within the area where radio waves can reach. 

On the other hand, the wireless LAN may cause the following problems to occur without proper 

security because radio waves can penetrate obstacles (including walls) to reach any places within a 

certain range. 

• Communication data is sniffed. 

Malicious third parties may intentionally intercept radio waves to sniff communication 

data as follow: 

– Personal information including user IDs, passwords and credit card numbers and 

– E-mails. 

• Network is invaded illegally. 

Malicious third parties may access to personal or corporate networks without permission 

to: 

– get out personal or confidential information (information leakage), 

– spoof as a specific person to distribute wrong information (spoofing), 

– intercept communication data, rewrite the data and send out the rewritten data 

(alteration) and 

– distribute computer virus to crack data and systems (cracking). 

Wireless LAN cards and access points essentially have security schemes to cope with these 

problems. Therefore, proper settings on security in wireless LAN devices can reduce the possibility 

at which these problems occur. 

It is recommended to be familiar with the problems in use of wireless LAN devices without security 

and provide proper security settings in your judgment and responsibility. 

If you cannot deal with security settings by yourself, contact your service representative. 

NEC does not assume any responsibility for any losses caused by problems occurred due to no 

security measures or unavoidable circumstances concerning wireless LAN specification.


Security Features Available for US40a 

NOTES: 

• To provide the following security settings for US40a, the access 

point to be used must support such settings. 

• These settings are only means to reduce security risks as much as 

possible but do not secure the safety of US40a completely. 

Preventing Sniffing (Intercept) 

The wireless LAN of US40a supports the WEP (Wired Equivalent Privacy) feature. Defining an 

encryption key by using the WEP feature, you can encrypt wireless LAN communication data 

among communication devices using the specific encryption key. This can prevent the 

communication data from being sniffed and the communication devices from being connected from 

unrelated PCs and devices. The WEP feature is divided into three types, or 64-bit, 128-bit and 152- 

bit WEPs. The wireless LAN of US40a supports all the types of WEPs. 

However, third parties may get the encryption key being set or decipher it with some encryption 

decipher technology. Thus, it is recommended to modify the encryption key periodically. 

NOTE: To use the WEP feature, remote communication devices must 

also support the WEP feature. 

Preventing Unauthorized Accesses 

• Setting a specific SSID (network name) to each of the access point and communication 

devices, you can prevent any communication device without the same SSID from 

connecting to US40a. However, the SSID may be known by third parties using devices 

which can detect SSIDs automatically. To avoid this, the SSID must be hidden at the 

access point so that the SSID may not be known. 

• If you register the MAC addresses (unique numbers assigned to network cards) of the 

connected PC and other devices in the access point, any devices other than those 

registered are disabled to connect to the access point (MAC address filtering).


Setting Security in Higher Level 

US40a uses the WPA (Wi-Fi Protected Access) feature proposed by the Wi-Fi Alliance. 

Using the user authentication based on the IEEE802.1X/EAP (Extensible Authentication Protocol) 

standard and TKIP (Temporal Key Integrity Protocol) or AES (Advanced Encryption Standard), 

each of which is an encryption method making decryption difficult further more than the 

conventional WEP feature, allow security setting at a higher level to be provided. 

NOTE: To use encryption based on WPA, remote devices to be 

connected to US40a must support the same security feature. 

Setting up Wireless LAN 

For how to set up the wireless LAN of US40a, see "Wireless Network Connection" described in this 

User’s Guide.


Available Wireless LAN Features 

The wireless LAN features available in US40a are described below. 

Wireless Connection of US40a with Peripheral Supporting Wireless LAN 

(Host Machine) 

Using US40a and an optional peripheral (host machine) supporting wireless LAN allows LAN to be 

used without cable connections. For example, US40a can be connected to Internet through a router 

or terminal adapter supporting wireless LAN. 

NOTES: 

• US40a can provide wireless LAN connection or communication 

with devices supporting 5GHz wireless LAN (IEE802.11a) in use of 

the 5GHz band or devices supporting 2.4GHz wireless LAN 

(IEEE802.11b or IEEE802.11g) in use of the 2.4GHz band. US40a 

cannot provide wireless LAN connection or communication with 

devices for other than 5GHz wireless LAN (IEE802.11a) and those 

for other than 2.4GHz wireless LAN (IEEE802.11b or 

IEEE802.11g). 

• US40a does not support ad-hoc connection in the IEEE802.11g 

mode.

the terminals or put the battery in the plastic bag. Failure to follow this may cause fire or 


Do not peel off exterior covers (such as coating and tubes) from batteries. 

Do not disassemble batteries.


Notes on Use of Battery in US40a 

NOTES: 

• When the battery is charged sufficiently, do not install or remove the 

battery pack from US40a if not required particularly. Failure to 

follow this may cause the battery pack to be defected. 

• Charge the battery as full as possible when charged. If you repeat a 

small amount of charging/discharging many times in low remaining 

battery status, some error may occur in the remaining battery level. 

Proper Use of Battery 

• To keep high display precision of the remaining battery level, refresh the battery 

periodically. 

• When US40a is not used for a long period, remove the battery pack with the remaining 

battery level of about 50% and save it in a cool place. This can lengthen the battery life. 

• When US40a is operated for a long time only by the battery, use the power saving feature 

of US40a. 

• The battery discharges naturally. It is recommended to charge the battery once for two to 

three months even if US40a is not used for a long period.


Action to be taken when remaining battery level becomes low during battery 

driving 

When the remaining battery level becomes low, the Battery Status LED lights or blinks orange. If 

this occurs, take either of the following actions depending on the situation: 

• When the AC power can be supplied to US40a through AC outlet: 

Connect the AC adapter to US40a to supply power though the AC outlet. As soon as the 

power is supplied, the Battery Status LED goes on and battery charging is started. US40a 

can be operated while the battery is charged. 

• When AC outlets are not installed: 

Terminate applications being used and turn off the power of US40a. 

If the power of US40a is not turned off still without power supply through an AC outlet, US40a is 

entered into the state set by [Power Options] in the [Control Panel].

This section describes how to set up the BIOS (Basic Input Output System). 

Before US40a is installed or an option device is added or removed from US40a, first read this 

section to understand the contents. 

Overview 

SETUP is a utility tool intended for basic hardware setup. The SETUP can be run without any 

exclusive utilities because is it normally installed in the flush memory area of US40a. 

Because the information provided by the SETUP is specified in the most standard and optimum 

state at the shipment of US40a, the SETUP is not required in most cases. Use the SETUP in the 

cases described below as necessary. 

IMPORTANT: 

• Ask the system administrator to operate the SETUP. 

• The SETUP allows you to set passwords. There are two levels of 

passwords, or supervisor and user. Starting the SETUP with the 

password in the supervisor level, you can change all items. If a user 

password is set, only a limited number of items can be changed. 

• Before the passwords can be set, OS must be installed. 

• The SETUP of the latest version is installed in US40a. Accordingly, 

the actual setting screens may be different from those described in 

this guide. For actual setting items, see the online help or contact 

your service representative.

NOTE: In the system configuration as described here, network devices 

like hubs and routers etc. have been omitted. 

US40a is a Thin Client terminal to be connected with a virtual PC. 

The minimum system configuration of Thin Client system requires only a single US40a and a 

virtual PC (see "Basic Configuration"). 

Adding DHCP server and download servers (FTP and HTTP servers) to the basic configuration can 

improve maintainability of Thin Client system (see "Extension 1"). 

An extended configuration allows you to use SSC (the management tool for VPCC) (see "Extension 

3"). 

In addition, you can use VPN for network environment to connect with virtual PC (see "VPN").


Basic Configuration 

The minimum system configuration for the Thin Client system requires only a single US40a and a 

server which hosts the virtual PC. Configure the network settings of US40a as the initial settings 

and specify the destination port of a virtual PC using the remote desktop connection. Then, you are 

ready to connect with the virtual PC. 

Basic Configuration 

• VPCC (Virtual PC Center) 

VPCC is a server that hosts a virtual PC. Windows XP Professional or Windows Vista 

Business, Enterprise Edition is available for the virtual PC. 

In addition to VPCC, US40a can connect with Windows Server 2003, Windows Server 

2008, and Citrix XenApp (Presentation Server 4.5).


Extension 1 

Adding DHCP server and download servers (FTP and HTTP servers) to the basic configuration can 

improve maintainability of Thin Client system. 

US40a can obtain the settings information from DHCP and download server (FTP or HTTP server). 

In a network using DHCP server, DHCP option information can be set for US40a and placing the 

setting information of US40a in the download server, multiple US40a can be configured at one go 

rather than setting each US40a individually. 

To adjust the system clock of US40a to those of servers, use the internet time server to synchronize 

the clock.

• US40a does not support "Auto Delivery of Remote Connections". 

Do not specify this feature in [Startup Program Setting].


Network Utilities 

The [Network Utilities] can be used to check network connection. You can use the Ping, Ipconfig, 

and netstat commands to check the network connection. 

Network Utilities 

Run any of the commands Ping, Ipconfig and netstat used to check the network status. 

Select a command and click the [Run] button. Then the selected command is executed. 

• Command 

Select the command to be executed out of Ping, Ipconfig and netstat. 

The default command is Ping.

Ping Diagnosis Utility 

Command "Ping" executes the ping diagnosis utility and displays replied messages. 

The diagnosis tool sends echo requests to the network host. The host parameter is the effective name 

of the host or IP address. Operating on the network, the host replies the echo requests. 

The ping diagnosis utility sends a single echo request every second, calculates the round trip time 

and packet loss statistics and displays a simple summary after completing the calculations. 

NOTE: All network devices do not always reply to ping packets. It is 

because Ping is a general feature used for denial-of-service attacks. No 

response from a device targeted by Ping does not always indicate that 

the device is unavailable for other purposes. 

Ipconfig Utility 

Command "Ipconfig" indicates the TCP/IP configuration. 

NOTE: You can check the MAC address of US40a in the normal 

network interface in the following steps: 

1. Open [Network Utilities] on the [Control Panel]. 

2. Select "Ipconfig" and execute it with option "/all". The MAC 

address appears on the Physical Address line in the execution result. 

netstat Utility 

Command "netstat" indicates the status of TCP connection under communication.

Software Update 

In order to update or additionally install software, US40a accesses to download servers through 

network and obtains the software of latest version. 

1. Software Update via Network 

The software update files for US40a will be stored in the folder of either the FTP or HTTP server. 

In addition to the above, the list of files "list.txt" that specifies the files to be obtained by US40a is 

also stored in the FTP or HTTP server folder. 

On the [Control Panel] of US40a, specify the IP address of FTP/HTTP server, folder name, and 

whether to perform update automatically or not. 

The time required for the update depends on the size of the file to be updated and the network load. 

Depending on the contents to be updated, US40a may require reboot during the update process. 

Before opening the update files, check the required time in the actual network environment.


2. Preparation 

The following describes the necessary preparation. 

2.1 Setup of FTP/HTTP Server 

Prepare the FTP or HTTP server that US40a uses to obtain the software of upgrade version. 

1. Prepare the FTP or HTTP server used by US40a to update the software. 

2. To allow access with Anonymous in the FTP server, enable it. 

3. Some limitations may be imposed for the types of files to be downloaded from the HTTP 

server. Check the settings of the HTTP server to add required settings. 

NOTES: 

• US40a normally uses [.msi], [.exe], [.txt], [.cer], [.pfx], [.p7b], 

[.bmp], [.gif] and [.jpg]. 

• To download the CER file, use FTP protocol. Using HTTP protocol 

may fail to download CER file depending on Web server. 

4. Create a new folder for US40a in the folder of the FTP or HTTP server. 

Ex.: To create folder "US40aUPDATE" for US40a in the default path of IIS. 

FTP: C: \Inetpub\ftproot\US40aUPDATE 

HTTP: C: \Inetpub\wwwroot\US40aUPDATE 

5. Store the update file in the folder you have created. 

6. Store file "list.txt" in the same folder. 

Create a list of files in list.txt which US40a captures from the folder. Create the list in the 

Unicode format.


2.2 Setup of DHCP Server 

By the factory default, US40a obtains network addresses from DHCP server. In the network that 

uses the DHCP server, you may skip the procedure to provide settings for update on US40a by 

using DHCP options. 

You can also specify not to use the DHCP server for update on US40a. 

• DHCP options to be used in US40a: 

The initial values of DHCP options for US40a are as follows. You may change DHCP 

Option No. by setting for US40a. 

– DHCP Option No.: 163 

Description: Select a protocol (FTP or HTTP) to be used in software update. 

Format: Byte 

Value: 0x0 if FTP is selected or 0x1 if HTTP is selected 


Description: Enter the name or IP address of FTP/HTTP server. 

Format: Character string 

Value: Server name or IP address 


Description: Relative path name in FTP/HTTP server 

Format: Character string 

Value: Path to the folder (in the example above, type as "US40aUPDATE".)


2.3 Setup for Update for US40a 

Update US40a in the following steps: 

1. On the [Control Panel] of US40a, click the [Update] icon. 

Update


2. Check the current settings in [Update] dialog box. 

If you want to change settings, click [Modify] and set parameters appropriately. 


• Use DHCP Options 

Check the [Use DHCP Options] checkbox to obtain settings information for update. Then, 

select DHCP Option numbers for items [Protocol], [Server Name], and [Server Relative 

Path]. 

Uncheck the [Use DHCP Options] checkbox when DHCP options are not used. Then, 

enter proper values for items [Protocol], [Server Name], and [Server Relative Path]. 

• Protocol 

Select a protocol used to obtain update files. Select the radio button of either FTP or 

HTTP. 

• Server Name 

Enter the name or IP address of the server from which the update files are obtained. 

• Server Relative Path 

Enter the path of the folder for saving update files in the server (in the example above, 

type "US40aUPDATE".)


• User Name 

When using the FTP server, enter the name of the user who accesses to the server. 

If an Anonymous user is specified, this box is grayout. 

• Password 

When using the FTP server, enter the password of the user who accesses to the server. 

If an Anonymous user is specified, this box is grayout. 

• Use Anonymous 

Check this checkbox to use anonymous. 

When checked, [User Name] and [Password] boxes are grayout. 

• Network Ready Retry 

Select a proper number from the pulldown list. 

If the network is not ready at update, connections are retried by the specified count. 

• Automatically update on booting 

If checked, US40a accesses to the specified server every time when it is booted, and 

checks the software version. 

If any updated software is found, US40a performs update automatically. 

• The check dialog of an automatic update start is displayed 

Check this to open the dialog of confirming whether the auto update is started or not when 

one or more update files are found in the download server. 

When [Automatically update on booting] is checked, the update confirmation dialog is 

displayed.


3. Executing Software Update 

Provide software update in the following steps. 

In Manual Mode 

1. Open [Update] out of the [Control Panel] of US40a. 

2. Press the [Update] button. 

Then the update processing is executed. 

In Auto Mode (at US40a booting) 

1. Select [Control Panel] → [Update] → [Modify]. Then, check [Automatically update on 

booting] on [Update Setting] dialog. 

2. Reboot US40a. 

Update is started at US40a booting.


4. Checking Software Version of US40a 

To check the version information on US40a, select [Start] → [Control Panel] → [Version 

Information]. 

NOTES: 

• US40a manages internally the versions of common.txt, certificates 

(.cer or others) and background image (.bmp) based on the time at 

which each of the files is created. For example, assume that US40a 

once read common.txt (created at 13:15 on November 15, 2007) 

uploaded to an FTP server. US40a will no longer read the 

common.txt having the same created time as long as US40a 

accesses to the same FTP server even if auto update on booting has 

been specified. 

• When the download server is changed, US40a may read common.txt 

of the same created time again. This is because, if the download 

server is changed from one to another, the created time of 

common.txt obtained from a server may be different from that 

obtained from another depending on the protocol and time zone of 

each of the pre-change and post-change servers. 

• By the default setting of US40a, auto update on booting is enabled 

and DHCP options 161, 162, and 163 are specified. If option 

numbers 161, 162 and 163 are already used for other purposes in the 

network system that uses DHCP options, you need to change the 

update settings of US40a.

Write Filter Settings 

This section describes how to set write filters. 

Features of Write Filter 

US40a uses FBWF write filters. With the Administrator account, you can modify all files in US40a. 

However, if data is written in the write filter enabled state, the modified data will be returned to the 

original at reboot of US40a. 

Therefore, before additional software and/or drivers can be installed in the Administrator account, 

write filters must always be invalidated. 

After US40a is modified completely, be sure to validate the settings of write filters to protect US40a 

file system. 

Write Filter Setting and Releasing Procedures 

Write filters can be set on the command prompt. First start the command prompt of US40a. 


2. Select [Run] out of the [Start] menu. 

3. Enter "cmd" and click [OK]. 

The command prompt starts. 

Indicating Write Filter Status 

Run the following command on the command prompt: 

FbwfMgr /displayconfig 

The setting of the current write filter and the one of write filter applied after rebooting appear. 

Invalidating Write Filters 

Invalidate write filters in the following steps: 

1. Run the following command on the command prompt screen: 

FbwfMgr /disable 

2. After confirming the following message appears, reboot US0a: 

File-based write filter will be disabled on the next reboot.

Validate the write filter in the following steps: 


FbwfMgr /enable 


File-based write filter will be enabled on the next reboot. 

Setting File Folders for Invalidating Write Filter Protection 

The FBWF write filter protection can be invalidated per file folder. Data written in a file folder 

whose protection is invalidated remains unchanged if US40a is rebooted. 

Setting Procedure 


FbwfMgr /addexclusion C: [file folder whose protection is to be invalidated] 

Ex.: Invalidating protection of folder C: \Program Files\NEC\TEST\Config 

FbwfMgr /addexclusion C: "\Program Files\NEC\TEST\Config" 


Path [file folder whose protection is to be invalidated] on volume C: will be in the 

exclusion list after the next reboot. 

Releasing Procedure 


FbwfMgr /removeexclusion C: [file folder whose setting is released] 

Ex.: Releasing setting of folder C: \Program Files\NEC\TEST\Config 

FbwfMgr /removeexclusion C: "\Program Files\NEC\TEST\Config" 


Path [file folder whose setting is released] on volume C: will not be in the exclusion list 

after the next reboot. 

IMPORTANT:

138 Operation and Maintenance 

Troubleshooting 

Problem when Using Combination of Two or More Thin Clients 

Failed to display images or animation of PowerPoint or Web page: 

→ While disconnecting US40a from the virtual PC without logging off and 

reconnecting to another Thin Client, ensure that the color depth is same for both 

the first and second connections. For example, if the color depth of the first 

connection of US40a to a virtual PC is 16 bits, then set the color depth of the next 

connection to the other Thin Client (e.g.: US100 or RDP Client of WindowsXP) to 

16 bits. When the color depths are not same for both the first and second 

connections, PowerPoint images and Web pages may not appear in the second 

connection. If there is a possibility that US40a may get connected from Thin 

Client having different color depth, in such case, do not disconnect US40a from 

the client at end of work rather log off US40a from the virtual PC. Especially, do 

not set the color depth to 15 bits for RDP connection of US100 in environment 

where US40a and US100 are used together. If the color depth is set to 15 bits, 

multimedia contents may not appear. 

Problems with Connections of RDP/ICA/Internet Time 

Failed to connect to RDP/ICA/Internet Time: 

→ If the failure still occurs after modifying NetBIOS name, specify the fullyqualified 

domain name 

Incorrect: Connect to: vpc-01 

Correct: Connect to: vpc-01.vpcc.nec.com 

Problems with Built-in USB SmartCard Reader 

Built-in USB SmartCard reader is disabled: 

→ At the startup of US40a, the [USB Smart Card reader] appears on [Safely Remove 

Hardware] on the task bar notification area. Although this is removable, but when 

it is removed the built-in USB SmartCard Reader can not be used. Do not remove 

built-in SmartCard Reader if you want to use it. In case you have removed it and 

want to use it again, you need to reboot US40a. 

NOTE: This problem occurs only when the firmware of version 

2008102201E is used.

Operation and Maintenance 139 

Problems with IC Card Manager 

Fail to switchover between terminals by using winlogon feature of IC Card Manager: 

→ With the current version of SecureWare/IC Card Issue Kit, winlogon does not 

support switchover between terminals. 

* winlogon: 

Logon user authentication of RDP connection by using ID/password stored in 

IC card. 

* Switchover between terminals: 

Remove the IC card from the Thin Client terminal and lock the screen, then 

insert the same IC card into another terminal and logon to connect to the 

original virtual desktop screen. 

* Authentication by Windows SmartCard using the certificate is available. 

With IC card of Std-9 format, a message "Failed to change/unlock PIN" is displayed: 

→ When the IC card is inserted into the IC card reader built-in US40a, you will fail 

to unlock PIN code through the IC Card Manager. To unlock PIN code, connect an 

external IC card reader to US40a, or use any other device such as personal 

computer. 

NOTE: This problem occurs only when the firmware of version 

2008102201E is used. 

Problems with Update Feature 

When [Automatically update on booting] is checked, a message "Failed to update" is 

displayed: 

→ Described below are probable causes. Check your system environment. 

– US40a is not connected to network. 

– Cannot connect with FTP server. 

– list.txt is not found. 

– Update file is not found. 

Update fails to obtain a file of ".CER" format: 

→ Using HTTP protocol to connect with IIS may fail to obtain a file of ".CER" 

format. Try again with FTP protocol. 

Problems with Printer 

Created a printer on US40a connected via RDP, but no printer is created on virtual PC: 

→ If model name of the printer of Japanese version is differ from that of English 

version, RDP connection from US40a will fail to create a printer on virtual PC. 

Use the printer of which names in Japanese and English version are identical.
