10.1.1  Use 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:

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. 

10.1.2  Command 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:
