Media Switch 

K2 Summit 3G media servers have four network ports. 

The two bottom are for control and the two top ones 

are for media networking. The control network ports 

are teamed together. Connect one control network 

port from each K2 Summit 3G to a switch and connect 

the K2 Dyno S Replay Controllers to the same switch. 

Connect one of the media network ports to a separate 

switch. In configurations with only one K2 Summit 3G, a 

direct connection can be made to a K2 Dyno S. If there 

is only one network switch, then create two VLANs on it 

to separate the control and media network traffic. 

All the valid configurations of K2 Summit and K2 Dyno 

S controllers are shown further along in this Application 

Note.

Software Setup (cont.) 

2. Set up IP Addresses 

To prepare the next step, a network 

address scheme must be created. 

Contacting the local network administrator 

may be required for help 

with this step. 

The next step is to assign an IP 

address to the network ports. This is 

accomplished in the following way: 

• Click on the “Start” menu, select 

the Control Panel 

• Click on “Network and Sharing 

Center” 

• In the next window, click on 

“Change adapter settings” 

• In the next window, right click 

on “Control Connection #1” and 

select “Properties” 


3



• In the General tab, scroll down 

until “Internet Protocol (TCP/IP)” 

is seen. Click on “Properties” 

• In the next window, the IP 

address is set 

• Select “Use the following IP 

address” 

• In the IP address line, fill in the 

IP address (in this example: 

192.168.10.150) 

• At the Subnet mask, fill in: 

255.255.255.0. Alternately, a 

network administrator will assign 

another value 

• Leave the rest blank, except when 

a network administrator indicates 

otherwise 

4 

www.grassvalley.com



• Click on “OK” and the IP address 

will be set 

• Repeat the steps above for 

“Media Connection #1” and 

have the last two digits of the IP 

address different from all other IP 

addresses being used 

• Write down the IP addresses to 

be used in the Host Table later 

3. Creating Hosts Table 

The Hosts Table is needed to set up 

easy media transfers between K2 

Summit 3G systems. 

First, it is necessary to determine 

the computer names of the K2 

Summit 3G servers. This is done in 

the following way: 

• On the desktop, right click on the 

“K2 Summit Client” icon 

• A selection box will come up. 

Select “Properties” and left click 

on it 

• The next window will have the 

necessary information 


5



• After “Computer name,” the 

current computer name can 

be found. In this case, it is: 

EJ12060448 

• Write this name down on a piece 

of paper 

• The other value needed is 

Workgroup. In this case 

GRASSVALLEY. All K2 Summit 3G 

and K2 Dyno S Replay Controllers 

must be in the same Workgroup 

• If it is necessary to change the 

Computer Name (see WARNING 

below) or Workgroup, click on 

“Change settings” 

• A new window will pop up 

• Type in a new Computer Name 

and or Workgroup and click on 

“OK” 

• Again, click “OK” 

• The computer indicates that a 

reboot is required to make these 

settings active 

• Click “Yes” to reboot 

WARNING: Be aware that when 

changing the computer name on a 

K2 Summit 3G media server that 

a new file system must be created 

and all existing media will be lost. 

Please refer to the K2 Summit 3G 

system manual for instructions on 

creating a new file system.

www.grassvalley.com



• The next step will be creating the 

Hosts Table. Browse to: 

C:\WINDOWS\system32\drivers\etc 

• Right click on “Hosts,” select 

“Open” 

• Another window will pop up. 

Select Notepad and click “OK” 


7



• Add the control network IP 

addresses of all K2 Summit 3G 

media servers and K2 Dyno S 

controllers on the network along 

with their computer names, from 

what was previously written. 

• To get the streaming file service 

working between K2 Summit 3G 

media servers, a special entry in 

the Hosts Table must be made. 

The IP address of the media 

network must be built in and 

“_he0” added after the computer 

name. Example of a host file is 

shown next . 

Note: Any line item with “#” (the 

pound or hash symbol) in front of it 

is disabled or inactive. 

Note: If adding a K2 Dyno 

Production Assistant (PA) system to 

this list, include it by using the same 

method of discovering its computer 

name and IP address settings as 

was just used for the K2 Summit 

3G media servers in the previous 

procedures. 

4. Creating a HOTBIN folder 

To be able to send clips from one K2 

Summit 3G media server using a K2 

Dyno S Replay Controller to another 

K2 Summit 3G media server using 

a K2 Dyno S Replay Controller, a 

HOTBIN folder must be created on 

the K2 Summit. To create a HOTBIN, 

follow these steps: 

• Double click on “K2 Summit 

Client” icon 

• Then double click on gvfs_ 

yourcomputername(V:) 

• In the next window select File/ 

New/Folder 

• This same information must exist 

on each connected K2 Summit in 

its Host Table 

• Click on “File/Save.” Do NOT save 

as a different name 

• Close this window 

8 

www.grassvalley.com



• Name this folder “IMPORTS” 

• Right click on the folder just 

created and select “Properties” 

• A new window will come up. 

Select the tab “Sharing” 

• Click on “Share” 

• Make sure “Everyone” has “Read/ 

Write” permission or use the 

scheme given by an IT department 

• Click on “Share”—a new window 

will pop up indicating that the 

folder is shared. Click on “Done” 

• Click on “Close” to close the 

IMPORTS properties window 

• On the desktop locate “K2 

Capture Services” and double 

click on it 


9



• In the K2 Capture Services select 

the “HotBin” tab 

• Put a mark in: use HotBin 

• If “V:\IMPORTS” has been 

created, leave the Source 

Directory. If a different folder is to 

be selected, browse by “Open” to 

find the folder to be used 

• In Destination Bin, fill in the Bin 

in which the clips should end up 

after importing 

• Adjust the other values according 

to the needs of a specific setup 

• Click on “Apply” and “Exit” 

• A new window will ask “Are you 

sure to exit the Summit Capture 

Services?” Click on “Yes”

5. Enabling Embedded 

Security 

With the configuration of the K2 

Summit 3G media server now 

completed, the next step is to activate 

the Embedded Security protection. 

Embedded Security will assure 

reliable operation by providing 

protection from viruses and other 

malware. 

• Click on “Start” and select All 

Programs\Grass Valley\Embedded 

Security Manager 

Note: If this was minimized previously, 

it can be maximized again by 

clicking on it in the taskbar. 

• In the next window select 

“Leave” 

• The Status will change from 

“Update” to “Enabled” 

• Close the Embedded Security 

Manager by clicking on “Close”

6. Setting Up Streaming 

Between K2 Clients 

To make fast and easy transfers 

possible between K2 Summit 3G 

systems, some additional changes 

in configurations must be made. 

If these next steps are not implemented, 

the system will work, but 

the discovery of other K2 Summit 

3G media servers on the network 

can take longer. To implement the 

configuration changes, take the 

following steps: 

• In AppCenter go to “System\ 

Configuration” 

• In the next window select Remote 

on the left side 

• Click on “Add” 

• In the Add Host box, type the 

host name that was put in the 

host table from other K2 Summit 

servers, then the name of the 

system being set up at present 

• As controller ID, enter 1 for the 

first one and if more are added, 

then increment this number 

• Click “OK”, and again on “OK”

7. Importing And Exporting 

Clips With Streaming 

Between K2 Summit 3G 

Media Servers 

Import: 

• In AppCenter go to “Clips\Import” 

• Select the “Stream” tab on the 

left 

• Select the K2 Summit that the 

media is to be imported from. In 

this example: NEWS_SUMMIT 

• Browse to clip(s) that are to be 

imported. Multiple clips can be 

selected by holding the Ctrl or 

Shift key and clicking on the 

desired clips 

• When done selecting clips, click 

on “Import” 


13



Send to (export): 

• In the Bin select the clip(s) to be 

sent to another K2 Summit 3G 

media server 

• In the next window, select 

“Stream” and the K2 Summit 3G 

media server to send the stream 

to. In this example: NEWS_ 

SUMMIT. Double click on it and 

browse to the Bin where the clips 

are to be dropped, and click on 

“Send” 

In both cases, in the transfer 

monitor of the sending and receiving 

K2 Summit, the progression of the 

transfer can be viewed. This feature 

can be found under “System\ 

Transfer Monitor” in AppCenter

8. Setting Up The K2 Dyno Replay Controller To Send Clips To Another K2 Dyno Operator 

The K2 Dyno application can copy/paste content between connected servers by way of the Library on the K2 Dyno S 

Replay Controller. A quick and easy way to push content from one system to another is the SEND function on the K2 

Dyno. 

To set up the SEND function on K2 Dyno, a few steps need to be taken: 

• After the K2 Dyno S Replay Controller has been powered up, press the Shift button and select Shutdown on the 

touchscreen 

• In the new screen that comes up, select maintenance mode 

• The K2 Dyno S Replay Controller will reboot 

• After rebooting, the standard Windows desktop will be seen 

• Set the IP-address and create (or copy from a K2 Summit) the Hosts Table as described previously in this 

Application Note 

• When completed, reboot Windows 

• In the box that pops up and asks about returning to Dyno mode, select “Yes” 

• When back at the K2 Dyno startup screen, configure the Dyno Session 

• To configure a send destination on K2 Dyno, press” CONFIG” on the touchscreen 

• At the top of the screen, the selection NETWORK can be seen and must be selected 

• Next, all the SEND destinations need to be added. To SEND a clip to another K2 Summit server, press “Send List” 

on the touchscreen. Shift+ADD will open the window to add a server location 

• Fill in the full path to the other K2 Summit server including the desired folder. The IP addresses cannot be used. 

The host names must be used. In the next example, it is the first line for the configuration that was made earlier 

The send paths are now configured. 

To SEND a clip to another K2 

Summit server, select it and press 

the Shift button on the K2 Dyno, 

and then on the touchscreen select 

SEND 

Note: K2 Dyno can send to any 

folder that can be browsed on the 

network that it has permission to 

write to. Without permissions, the 

transfer will fail. 

The clip will now be transferred over 

the network to what is set up as 

the SEND destinations. The clip will 

arrive on the other K2 Summit 3G 

media server in the HOTBIN folder 

previously created and will be automatically 

imported. Other users can 

find the clip located in the LIBRARY 

bin and then select the IMPORTS 

bin.

There are two ways to work using this setup: 

• Multichannel mode: The first K2 Dyno S operator 

starts the session and uses a configuration of 2 in / 

2 out. The second K2 Dyno S operator selects “join 

session.” K2 Dyno operator 1 uses P1 and the other 

K2 Dyno operator uses P2. Both K2 Dyno operators 

will work independently from each other, but share the 

same inputs, and the same highlights. 

• On-air preview mode: The first K2 Dyno operator 

starts the session and uses a configuration of 2 in 

/ 2 out. The second K2 Dyno operator selects join 

session. K2 Dyno operator 1 uses P1 and the other 

K2 Dyno operator uses P2. By pressing SHIFT+P1 the 

K2 Dyno application will switch into PGM/PVW mode. 

The first K2 Dyno operator will control PGM (P1) and 

the second operator will control PVW (P2). The PGM 

output is used for on air playback and the operator on 

the PVW will cue up clips that should be played next. 

With the TAKE button, the clip loaded in PVW will be 

played back on the PGM output. 

Note: The first K2 Dyno S Replay Controller cannot 

be connected to Control1 and the other controller 

connected to Control2 on the K2 Summit server. On 

the K2 Summit server, both control ports are teamed 

and have the same IP address.
