Appendix K: Sp3 Control Via Rs232 & Tcpip - Bryston SP3 Manual

APPENDIX K
1. Bryston Serial Protocol command set for SP3.
SP3 receives control commands and responds back to the host controller following an
execution of each command. SP3 can also be configured
automatic responses through RS232 or TCP/IP upon certain system events such as input
source switching or volume level setting from the front panel or by IR remote controller.
The following commands can be sent over RS232, RS485 (with a RS232/RS485
interface) and TCP/IP (using GET mechanism over port 80).
Command format
ASCII strings ended with carriage return (code 13) or dot (.).
#D1D2C1C2C3C4P1P2...<CR>
# command start character (RS232 only, in TCP/IP use URL code %23 instead)
D1 device category, one digit 1..f (for SP3 D1 must be 1)
D2 RS485 device ID, 1 digit 0..f(dflt=0). D2=0 typically and can only be changed
through the front panel menu!
C1..C4 command name (4 chars) , typically uppercase ASCII letters.
P1,P2 parameters are two or more arbitrary ASCII characters.
<CR> Special end char, ASCII code 13 (RS232 only, in TCP/IP use dot '.' instead)
RESPONSE FORMAT
The Response format is the same as commands, repeating the D1,D2,C and P bytes (P
bytes may carry either an actual status value or ?? in case of errors).
Example (TCP/IP):
%2310MPWR01.

SP3 may have additional unsupported commands that are exceptions to Bryston Serial Protocol, for
example a common help displaying command is a single question mark character
diagnostic commands that are implemented for the purpose of trouble-shooting. The special commands
should never be used by controllers and in automated remote control scripts since they are not guaranteed
to be supported in all future product revisions!
