7.1.1 Protocol Requirements
• Sources and destinations are numbered starting at 0.
• All commands begin with the ASCII STX character (02H).
• Receipt of STX in the middle of a command discards all collected bytes and begins a new
command.
• Errors of any kind (e.g., missing parameters, unexpected characters, out of range values, etc.)
result in discarding the current command.
• Parsing will not tolerate any additional characters within a command. For example, spaces
embedded within a command will cause the command to be discarded.
• Audio crosspoints are ignored on switching requests. In the Command Response message, the
audio source is always reported as ‘0’ (30H).
• The Power Supply status returned in the Command Response message is always reported as ‘3’
(33H), which means okay.
• The protocol requires 2 digits to specify a destination. This 2-digit number represents a
decimal number. For example, a destination that is specified with a high digit of ‘1’ and a low
digit of ‘2’ represents the decimal number 12.
