4 Programming Hints 

Before installing the modem it has to be programmed in order to meet the demands. 

The baud rate and data format for connecting to the target device and 

the transmission mode and transmission rates must be adjusted. On delivery 

the following default parameters are active (if not differently mentioned, see 

terminal cover): 

ATS0=1 This parameter setting determines the number of rings (here 1) before automatic 

answering 

AT&D0 This parameter determines how the modem responds when circuit DTR is 

changed from ON to OFF during data mode. With setting 0 the modem ignores 

DTR 

ATE0 No local echo 

ATQ0 V0 Result is presented as number 

It is possible to adjust other device specific parameters, too: 

� Analogous (PSTN) and ISDN modems (UniMod 01/I, UniMod 01/ISDN, 

Metcom T A.., Metcom T I..) 

AT%C0=0 Disable data compression according V.42bis 

Only ISDN: 

AT**BSIZE=256 

AT+CBST=7,0,1 

(AT+CBST=0,0,1) 

Fixed local baud rate on the serial interface: 9600 Baud; 

Data format: 7 data bits, even parity, 1 stop bit (7E1) 

Data frame length: 256 bytes 

� GSM modems (Metcom T M.., UniMod GSM / GSM-2 / GSM-3 / GSM-4) 

The modem selects the bearer service with data rate 9600 Baud (V.32), asynchronous, 

non-transparent mode to be used when data calls are originated 

(automatic) 

If you want to change these parameters, a PC with a free RS232 interface is 

needed. Moreover experiences with the Hayes AT modem command set are 

highly recommended. To establish connection between PC and modem use a 

converter ("converter box") in order to adapt the interfaces. Alternatively a parameterization 

adapter can be used: 

� UniMod..: The adapter* can be plugged instead of the interface module. 

� UniMod GSM-2 and UniMod GSM-3: The adapter* can be plugged into the 9 

pole plug RS232 interface near the interface module. 

� Metcom T..: The adapter* can be plugged into the RJ45 interface from Metcom 

T.. (RS232). 

*: This adapter can be ordered as accessory.

Examples: 

4.1 UniMod... with parameterization adapter 

First set the switch to position 

"�01L/�GSM ", as shown in the 

picture. Then connect the 25 pole 

plug (RS232) to the PC. 

Disconnect the modem from the supply 

(important!) and remove the interface 

module. 

Insert the 7 pole plug of the 

parametering adapter instead of the 

interface module. The notch must 

point in direction of the LED’s on the 

top. 

After programming switch off the 

UniMod and insert the interface module 

carefully again.

4.2 UniMod GSM-2 / GSM-3 / GSM-3+ / GSM-4 with RS232 parametering 

cable 

Alternative for UniMod GSM-2, 

GSM-3, GSM-3+ and GSM-4: 

parametering cable with 9 pole 

plug (standard RS232 - 1:1). 

4.3 Metcom T.. with RS232 parametering adapter 

Fig.: Connection between RS232 cable and UniMod 

GSM-2 

First insert the RJ45 plug of the parametering adapter to the Modem as shown 

in the picture. 

Then connect the 9 pole plug (RS232) to the PC. 

Turn on the PC and start the parameterization software.

6 Configuration 


With the UniModSet software, the device can be set up, put into service and diagnosed 

easily & conveniently. 

After start of UniModSet select the tab for the device and "�Assign" for: 

� Baud rate, e.g.: 9600 Baud 

� Data format, e.g.: 7E1 

� Control, e.g.: ignore DTR, no handshake 

� Responses, e.g.: as numbers 

� Automatic unhook after 1 ring signal 

It is possible to adjust other device specific parameters, too: 

6.1 Analogue / PSTN for UniMod 01/I, Metcom T A.. 

11


12 

With password authentication 

enabled the modem asks the 

remote station immediately after 

the CONNECT message for 

the password. The correct 

password (factory default: 

"modem1") then must be sent 

by the remote station to the 

modem. When the password was entered correctly the connection is established. 

If the password was wrong the modem performs a reset, which causes it 

to hang up. 

Changing the password can be done by means of the "Change password" button. 

The default password is "modem1". 

At modems which are equipped with an internal clock (old version UniMod 01/It 

or Metcom T A..C01, undeliverable!) you can adjust the time and set the unhook 

time window (e.g. from 23:00 to 05:00). The modem will unhook only in this 

time. 

Optional it is possible to activate SMS. This function is monitoring on/off state 

changes of DTR input (this function is possible only at areas of the German 

Telecom for the devices Metcom T A..C01 or UniMod 01/It): 

� For versions until May 2006: Possible only with devices including an internal 

clock: UniMod 01/It or Metcom T A..C01; Please indicate during ordering! 

� For versions since June 2006: Possible with all devices:


It is possible to select the transmission mode (this command determines which 

type of error correction is the preferred choice to be employed for future connections): 

� Secured mode V.42 LAPM or MNP4 error correction. If such a link is not 

possible, a reliable link is attempted (command AT\N3, default). 

� Direct mode (activated by the command AT\N1). The modem has no influence 

in direct mode on the transmission format. Data is transferred without 

buffering. Data compression or error correction does not function in direct 

mode. 

Data Transmit Control is a firmware integrated feature for supervising the online 

data transfer. The feature prevents the modem from staying online infinitely, 

even if no data are transferred at all. 

� It is not possible to read the baud rate or data format from an analogue 

modem!

6.2 GSM / GSM-2 for UniMod GSM, UniMod GSM-2 und Metcom T M.. 

Additional: For dual band modems UniMod GSM-2 (with TC35-Modul) it’s possible to set / 

activate some additional functions. 

Optionally the time-controlled modem-reset can be activated. With this turned 

on the modem is regularly deactivated by the internal firmware. After the reset it 

logs on to the PLMN (Public Land Mobile Network) again. Activating is recommended 

when the field-strength of the used GSM-net is very low.


It is also possible to activate the password for remote programming (Remote 

Control) and authentication after establishment of connection. Default password 

is "modem1". 

The internal CPU can optionally send the SIM PIN to the modem. This is useful 

when using a SIM card which demands the PIN to be entered after power failure. 

Optionally the network operator can be set (factory default: “automatic selection”). 

With the default setting („automatic selection“) the modem logs into the strongest 

available & permitted network. At frontiers it is therefore possible that the 

modem logs into a network of the neighboured country, which entails higher 

telephone costs. To avoid this, the network operator can be selected manually. 

Activate prepaid SIM-cards (or cards without a data service): only if the function 

is needed! 

15


16 

Optionally it is possible to activate SMS. This function is monitoring on/off state 

changes of the DTR input. Maximum of message text are 35 characters. 

It is possible to unlock the SIM card with PIN or to change the PIN: 

As well as to check the signal quality of a connected UniMod GSM, UniMod 

GSM-2 or Metcom T M..: 

The top indicator shows the average field strength, the one below shows the 

field strength at the moment.


Optionally the field strength at the place of the remote modem can be checked 

(Metcom T A.. or UniMod GSM-2). This will need a special version of the device 

which can be ordered at the manufacturer. 

� The password for local and remote modem must be differently (if you use 

two UniMod...). 

In order to fulfill that request, the parameters of the local modem (baud rate and 

data format) have to be set correctly first in the menu "Remote Modem". 

After that, you have to enter the telephone number and the correct (!) password 

for the remote modem. 

Click on the button “Connect”: link to the remote modem (wait for 1 minute 

max., depending upon the network connection). 

With the “Read” check box, communication to the remote modem will be enabled. 

If the check box “Info” is selected, additional information from the remote 

device will be read (e.g. Firmware version). This feature increases the readout 

time slightly. The check box “GPRS (Timeout)” enables adjusting the timeout for 

the GPRS communication (up to 20 sec.). 

17


18 

Select the tab “Signal Quality”: 

A short time (15 seconds max.) after selecting the tab "Measurement" the field 

strength of the remote modem will be shown: 

Cell information: 

Chann: Cannel number 

Loc AC: Location area code 

Cell ID: Cell identification 

At the end of the remote reading session press “Disconnect“ in the “Remote 

Modem” menu in order to terminate the modem connection.

6.3 GSM-3 for UniMod GSM-3 / GSM-3H / GSM-3+ 


With the GPRS dual-band modems of the UniMod GSM-3 (incl. 3H und 3+) series 

(with TC45/MC55-modules) additional functionalities beyond the ones for 

UniMod GSM-2 can be activated. 

Optional it is possible to activate the protocol: 

� Mode A with fixed baud rate (default) 

� Mode B with baud rate switching according to IEC 62056-21 (former IEC 

61107) without acknowledge (ACK) 

� Mode C with baud rate switching according to IEC 62056-21 (former IEC 

61107) with acknowledge (ACK) 

For the data format “7E1” the parity (“Radio 7E1”) can be disabled. In this case 

the data format by radio is 8N1. 

UniMod GSM-3+ only: optional it is possible to activate an internal (on board) 

RS485 interface.

is "modem1". 








Since November 2006 (version #46, see: „Info – Modem type“) Prepaid SIMcards 

(or cards without a data service) can be used within the UniMod GSM-3. 

Activate prepaid SIM-cards (or cards without a data service): only if the function 

is needed!




Since August 2005 (version #44, see: „Info – Modem type“) the UniMod GSM-3 

supports the programming of up to four telephone numbers and message texts 

(two for “closing” and two for “opening” the SMS-input). 

After clicking the “Additives” button, further telephone numbers and message 

texts can be entered: 

� Sending SMS is only possible with deactivated „automatic baud rate 

adaption (IEC 62056-21/61107 local)”-function (submenu: “Baud rate 

switching”). 

21


22 

More options can be set by means of the “Baud rate switching” register: 

� “Reaction times (for mode B or C only)“: According to the IEC 62056- 

21/61107 norm, the reaction time between receiving and sending a telegram 

has to be within 200ms and 1500ms. However, this can not be guaranteed 

for GSM/GPRS transmission. Therefore the delay can be increased manually 

up to 15 seconds. 

� „Temporary baud rate switching possible (remote control)“: The baud rate of 

the electrical interface can be changed dynamically during the acquisition job 

without hanging up in between. This functionality enables retrieving data 

from meters with different baud rates (e.g. 2400Bd & 9600Bd) and different 

data formats (e.g. 7E1 for IEC-, 8N1 for DLMS- and 8E1 for M-Bus protocol) 

within one call. The command for adjusting the baud rate respectively data 

format is described in the modem manual. 

� „Automatic baud rate adaption (for IEC 62056-21/61107 local)“: The local 

baud rate to the meter can be adjusted automatically when switching on the 

modem (Auto baud rate). For further information please refer to the modem 

manual.

The following registers exist for GPRS transmission: 

� Parameters for GPRS network operator: 


� Parameters for GPRS-Bridge: 

Host server (Remote-computer which runs the GPRS-Bridge) incl. User 

name, Password and Modem-identification (Modem-identifier/TCPidentification) 

for establishing the connection (BAER protocol): 

� Timeout: 

- By means of “keep alive” the interval can be set in which characters will be 

sent regularly to the GPRS-Bridge. This procedure supports keeping the 

GPRS-connection established. 

- If a connection to the GPRS net can not be established after certain connection 

tries („Number of TCP connect request“), the modem switches automatically 

to the CSD-mode (dial mode). 

- After a settable pause (Time delay CSD −> GPRS) the modem tries again 

to log into the GPRS net (internet). 

- In “Half duplex“-operation the receive-buffer will be deleted while sending 

data.

It is possible to read the temperature at the UniMod GSM-3 (menu Remote 

Modem, see UniMd GSM-2 too):

6.4 GSM-4 for UniMod GSM-4 


With the GPRS quad-band modems of the UniMod GSM-4 series (with Telit- 

GE864 modules) additional functionalities beyond the ones for UniMod GSM-3 

can be activated. 

Option: since firmware version #90 is possible to do a firmware update via local 

interface (e.g. service RS232) or via mobile (GSM/PSTN modem or GPRS) 

connection (see page 35). 

Optional it is possible to activate the protocol:

In order to fulfill that request, the parameters of the local modem (baud rate and 

data format) have to be set correctly first in the menu "Remote Modem". 

After that, you have to enter the telephone number and the correct (!) password 

for the remote modem. 




If the check box “Info” is selected, additional information from the remote 

device will be read (e.g. Firmware version). This feature increases the readout 

time slightly. The check box “GPRS (Timeout)” enables adjusting the timeout for 

the GPRS communication (up to 20 sec.). 

Note: For data format = 8N1 (needed for firmware update) is possible to set the check 

box “Remote 7E” for correct reading the settings from the remote UniMod GSM-

2 nd modem: "Box to Box Client"

7 Change the configuration 


Select the serial port (e.g. COM1) in the "Settings” -> “Interface” menu and send 

("�Write") the chosen device configuration to the UniMod... or Metcom T... 

Additionally the configuration from a connected device can be loaded 

("�Read"): 

The changed configuration parameters can be written into the connected Uni- 

Mod… or Metcom T... by means of the "�Write" button on the right side (under 

the “Equipment configuration” headline). 

� Please select first the correct PC-interface (COM1 to COM29). 

Configuration parameters from the device can be read out by clicking on the 

"�Read" button. Additional information (e.g. SIM-card and network operator for 

GSM-modems) can also be read from the connected modem. 

� It is not possible to read the baud rate or data format from an analogue 

modem! 

8 Save the configuration 

The "File" menu permits saving the actual configuration ("Save as...") or loading 

an existing one ("Load…").

9 Remote Modem (Remote Control) 

Settings for connection between the local modem and a remote modem for remote 

control; 

Possibilities: 

� Test for connection between the remote modem and the remote meters via 

terminal or protocol test (optionally); 

� Optionally the field strength at the place of the remote modem can be 

checked ; 

This will need a special version of the device (parameterising) which can be 

ordered at the manufacturer: 

� Configuration parameters from the remote modem can be read out: 

� The changed configuration parameters can be written into the connected re- 

mote modem: 


two UniMod... or Metcom T...). 

In order to fulfill that request, the parameters of the local modem (see page 9) 

have to be set correctly first in the menu "Settings – Local modem". 

After that, you have to set the baud rate and the data format, to enter the telephone 

number and the correct (!) password for the remote modem (input template 

“Remote Modem”). 

Note: from UniModSet-Version 7.00 is it possible to activate two different types of 

connection: 

� Serial modem connection with phone number, e.g. 001701234567; 

� TCP/IP connection, e.g. IP10.20.30.40:1234 (standard port := 1234), possible 

only for UniMod Ethernet and UniMod GSM-4 with fix IP-Address 

( );

Possible settings: 



If the check box “Info” is selected, additional information from the remote device 

will be read (e.g. SIM-Card, network operator, firmware version). This feature 

increases the readout time slightly. 

The check box “GPRS (Timeout)” enables adjusting the timeout for the GPRS 

communication (up to 20 sec.); default := 5 sec. 

For data format = 8N1 (needed for firmware update) is possible to set the check 

box “Remote 7E” for correct reading the settings from the remote UniMod GSM- 

4 (with data format 7E1) 



ONLINE: Remote reading session is active; 

At the end of the remote reading session press “Disconnect” in the “Remote 

Modem” menu in order to terminate the modem connection.

10 Terminal 

Experienced users can alter the device configuration with the internal terminal 

program using AT commands. 

Inputs can be made by keyboard or the Function-buttons at the right of the window. 

The twelve "function keys" can be programmed with arbitrary strings, 

which simplifies the input of often used commands. By simple clicking one of 

these buttons you can send the programmed text to the modem. The text can 

be defined using the button "Function keys". 

The button "clear puffer" will erase the contents of the terminal. 

The text can be defined using the button "Function keys":

10.1 Programming with the terminal software 


First set your terminal program to the fixed, local data rate and data format of 

the modem (default values: 9600 Baud, 7,E,1). Use one of the AT commands 

(e.g. ATS0?, ATI, AT&V) in order to check whether the modem answers. If you 

see the answer on the screen, the interface is working correctly. 

� Simply typing AT does not necessarily result in an answer, because the 

modem can be programmed not to send messages and echoes (using parameters 

ATQ1 and ATE0). 

Every AT command begins with the letters AT. Upper or lower case letters may 

be used, but the leading characters must be in the form "AT" or "at". 

Some examples of AT commands (the answers depend upon the respective 

firmware version):

Saves the current parameter setting in the user-defined profile. 

This settings are active after every resumption of power supply! 

� possible by UniMod GSM only 

� At the end of every programming the settings have to be saved permanently 

using the at&w command. This ensures that the parameters are restored 

after power failure. 

Example (e.g. UniMod GSM or Metcom T M..): 

� Establish connection PC to modem (e.g. using the parametering adapter). 

� Insert SIM card. 

� Switch on Metcom T M../UniMod GSM. 

� Start terminal program and set data rate correctly. 

The modem does not reply to a simple AT command by default. In order to 

test communication you have to use a command which results always in an 

answer (e.g. ATI or AT&V). This should give an readable output on your 

screen. 

� Input AT&F to restore factory settings. Modem should reply OK. 

� Set data rate of your terminal program to 19200 Baud and data format to 

8N1. 

� Ask modem for PIN status: Input AT+CPIN? Possible answers are: 

+CPIN: SIM PIN PIN not active; enter PIN (see below) 

+CPIN: READY PIN active 

� Enter PIN: AT+CPIN="1234" (if PIN=1234). Modem reply: OK 

� Unlock PIN: Enter AT+CLCK="SC",0,"1234". Modem reply: OK 

� Check GSM network operator ("bearer"): Enter: AT+COPS? 

Possible answers are:

� Signal quality: Enter: AT+CSQ, Modem reply: value from 0 (bad) to 31 (very 

good). For data calls signal should be more then 19. 

� Select data rate for target device (e.g. counter): 

AT+IPR=2400 (if device operates at 2400 Baud). Modem reply: OK 

Possible data rates: 300, 1200, 2400, 4800, 9600, 19200 (Default), 28800, 

38400 or 57600 Baud 

� Set parameters for terminal program to 2400, 8N1. 

� Set data format: AT+ICF=5,1 (if device uses format 7E1). Modem reply: OK 

Alternative: AT+ICF=3,3 (default value) if device uses 8N1 

AT+ICF=2,1 if device uses 8E1 

� Set parameters for terminal program to 2400, 7E1 

Alternative: 2400, 8N1 

2400, 8E1 

� Select automatic answering: ATS0=1, Modem reply: OK. 

� Disable echo: Enter ATE0, Modem reply: OK. 

With this setting the modem does not echo characters sent by the target device. 

Some counters may not communicate correctly if they receive their own 

output. 

� Suppress modem result codes: Enter ATQ1. No answer from modem. 

This prevents the modem from sending result codes to the target device. The 

result codes can cause trouble with some counters. 

Alternative: ATQ0 V0 (Responses as numbers), Modem replay: 0 

� Save current parameters: Enter AT&W. No answer (if ATQ1 command issued 

before) 

or answer=0 (if ATQ0 V0). 

� Parametering finished.

11 Protocol Test 


With the program-expansion "Protocol Test" (optional) is it possibly to make 

connection to the counter and to enforce a simple counter test („Read Data“).
