Chapter 5: Communication Protocol
Set Audio Only Crosspoint
Cmd = 4
Databytes = destination, source
i.e. to switch audio on output 3 to input 4
CMD = 3
Databytes = 3,4
Mute Video on specified output
Cmd = 5
Databytes = Destination, State (0=off, 1 = on)
i.e. to turn video off on output 3
CMD=5
Databytes = 3,0
i.e. to turn video on on output 3
Mute Audio on specified output
Cmd = 6
Databytes = Destination, State (0=off, 1 = on)
i.e. to turn audio off on output 3
CMD=6
Databytes = 3,0
i.e. to turn video on on output 3
CMD=6
Databytes = 3,1
Split Crosspoints - Video and Audio Differently
Cmd = 7
Not specified yet but will exist
Get Current Status
CMD 8 = current Status all
Databytes = Destination. (1-16 = specific output, 0xff = all)
i.e. to read the status of output 3 send;
CMD = 8
Databyte = 3
i.e. to read the status of all outputs
CMD=8
Databytes = 0xff
Unit will return Valid PSU as above where databytes is;
a single byte indicating currently selected source if specific destination was requested
or a string of 16 bytes indicating currently selected source for each destination starting with destination 1.
