APPENDIX B
SP3 BRYSTON SERIAL PROTOCOL
HELP FILE
Rel. 5, 21-Dec-2011 (updated 2013-08-12)
SP3 receives commands and send responses
to each command. It can optionally broadcast
automatic responses to certain system events
such as source switching by the front panel
etc. (see AUFB). The format of the automatic
responses is the same as the response to a
serial command sent with the parameter bytes
P1 P2 = "QS".
Command format are all ASCII strings with the
carriage return ending:
# D1 D2 C1 C2 C3 C4 P1 P2 ... <CR>
# - command start character
D1 - device category, 1 digit 1..f(SP3=1)
D2 - RS485 device ID, 1 digit 0..f(dflt=0)
(D2 can only be changed through
the front panel menu!)
Currently D1 D2 must be "10".(*)
C1..C4 - command name (4 chars)
P1,P2,.. - parameters n>=2 chars (variable)
<CR> - end character (code 13 or '\r' in C/C++)
Example:
#10MPWR01<CR>
NOTE: ANY CHARACTERS PRECEEDING # AND
FOLLOWING
THE <CR> WILL BE IGNORED BY SP3. DO NOT
INSERT #, SPACES, <LF>, <TAB> OR OTHER
NON-PRINTABLE CHARACTERS INSIDE THE
COMMAND.
Response format is the same as commands,
repeating the D,C and P bytes (P bytes may
carry the actual status or ?? as error marker)
Example:
#10MSRC00<CR>
NOTE: DO NOT ASSUME THAT THE NUMBER OF
RESPONSE
BYTES R1,R2.. IS ALWAYS FIXED. ALLOW UP TO
320 CHARS AND READ ALL UNTIL <CR> AT THE
END.
