5.3.2 Description of Parameters
5.3.2.1 Address
The target address 255 sends a broadcast command to all channels. You can select AV output cards using the
camera list in the next parameter.
5.3.2.2 Camera List (Parameter 1)
OSD commands are executed by all AV output cards that display one of the camera IDs from the camera list.
This camera list may contain following items:
•
Camera IDs separated by commas.
Example: 1,3,4,5,6,8,10
•
Range of camera IDs.
Example: 3-6
•
Combination of both.
Example: 1,3-6,8,10
•
Predefined group of camera IDs.
Example: g2
Groups are only supported by receivers of type matrix. They can either be created using the group command (see
table 5-2) or by using the optional Camera Control Software.
The receiver stores a defined group permanently. Instead of a camera list you can then use the group name (g1 to
g15) to address the selected cameras. If camera Ids change, you only need a change the group and not the camera
list in the command.
