Communication Protocols

10.1.1Use of Kramer Machines

A router may be represented via the Kramer protocol as a maximum of two machines. Based on the largest supported, 8 level switcher, the levels correspond accordingly:

Level	Machine #	Function
1	1	Video
2	2	Video
3	1	Audio
4	2	Audio
5	1	RGB Mute
6	2	RGB Mute
7	1	Audio Levels
8	2	Audio Levels

Parameter Terminology:

Setups - Setup # 0 refers to the present switcher status. Setup # 1 and higher are the settings saved in the switchers memory, (i.e., those used for store and recall).

Bi-Directional- specifies a bi-directional command. If the switcher receives the code, it will perform the instruction; if the instruction is performed, the switcher will use the same codes for its response.

10.1.2Command Details

“Switch Video”: Switch Video Crosspoint”

Request: 0x01 <input> <output> <machine>

Response: 0x41 <input> <output><machine>

Action: Set output to input

The “Switch Video” command is used to request that a connection be made. Input and output are specified in hexadecimal notation. If 0 is specified for output, all outputs will be switched to the specified input. If 0 is specified for input, the specified output will be disconnected (Video Mute). Bi-Directional command example:

	Command	Meaning
Command To Switcher	0x01 0x85 0x88 0x81	Connect video input 5 to output 8
Response From Switcher	0x41 0x85 0x88 0x81	Video input 5 connected to output 8
