Table 5.4 describes the command parameters.
An offset of -1 is required so that the lowest value of 000 points to the router input or output number 1. In this way,
inputs and outputs from 1 to 255 can be addressed with dialogue values from 000 to 254.
Switch an input to an output using a defined breakaway
Start the sequence (11 bytes) with an upper case <X> followed by the destination, source, breakaway and carriage
return as detailed below. Do not include the parentheses.
<X> <ddd> <,> <sss> <,> <b> <CR>
Response from SCP
• If the data sting is valid, the SCP returns response (B).
• If the data string is invalid, the SCP returns response (A).
• If the data string is valid but the source number is unavailable or any of the parameters are incorrectly specified,
i.e. greater than 254 (255 to 999) for destination and source and greater than 1 to 8 (0 or 9) for breakaway, the
SCP returns response (A) then response (B).
Response (A)
<CR> <LF> <ERROR> <CR> <LF>
Response (B) <CR> <LF> <OK> <SP> <CR> <LF>
Switch multiple inputs (one per level) to a output
Start the sequence (37 bytes) with an upper case <Z> followed by the destination, then a source (or <---> to not
switch a level) for each of 8 levels and carriage return as detailed below. Do not include the parentheses.
Send <---> in place of <sss> to not switch that level.
Response from SCP
• If the data sting is valid, the SCP returns response (B).
• If the data string is invalid, the SCP returns response (A).
• If the data string is valid but the source number is unavailable or any of the parameters are incorrectly specified,
i.e. greater than 254 (254 to 999) for destination and source and greater than 1 to 8 (0 or 9) for breakaway, the
SCP returns response (A) then response (B).
Response (A)
<CR> <LF> <ERROR> <CR> <LF>
Response (B) <CR> <LF> <OK> <SP> <CR> <LF>
