NTI AUDIO/HD VIDEO MATRIX SWITCH
11
Command Protocol
CPU controller commands supported by the unit are defined below. All commands should be terminated with a <CR> (carriage
return). When a command is sent, the entire string is echoed back to the CPU along with a response from the addressed unit as
shown in the command definitions. All characters should be upper case, and all numbers below 10 should have a leading 0 (ex: 1
= 01).
NOTE: For units with one output or user port, use 01 for the output select.
Legend:
(All numbers must be two digits)
SW : Switch (01-15) MM : Save Into Memory Bank (00-09)
BR : Baud Rate Code (12,24,48,96) LL : Load From Memory Bank (00-09)
OP : Output Port (01-MAXOUTPUTS) <CR> : Carriage Return (Hex 0xD)
IP : Input Port (01-MAXINPUTS) ip
: IP address

If the first field is not a known command (as listed above) or SW field is different from the serial address programmed in the switch
memory, the command will be ignored. If the SW field corresponds to the serial address, but the syntax is wrong after this field,
the switch will answer with ?<CR>.
