Commonly Used Switching Commands 

This section contains the most commonly used switching commands. These commands are 
explained in detail in the proceeding. 

“Y” Command- All Levels 

The “Y” command switches all levels (i.e. video and audio). 

For example; 

**Y2,8!! 

This requests that input 8 be connected to output 2 on all levels. 

“X” Command- Specify Levels 

Using the “X” command requires that a level is specified. 

For example; 

**X8, 3, 2!! 

This requests that a connection is to be made between output 8 and input 3 on level 2. If a 
level number of “0” is used, all levels are switched. 

“V” Command- Connect Levels 

The “V” command is followed by an output number, a comma, and an input number for each 
level, up to the number of levels on the routing switcher. 

For example; 

**V12, 7, 8, 9!! 

This requests that connections are to be made to output 12 from input 7 on level 1, input 8 on 
level 2, and input 9 on level 3.
