After the delay synchroniser has been powered-up, an initialisation string is sent
“Initialising SC2”.
Following are the commands and the expected responses:
Command
Description
Response
Bnn:
- Baud Rate
- ACK: (at old rate)
nn=11 (115200)
nn=57 (57600)
nn=38 (38400)
nn=19 (19200)
nn=96 (9600)
CSD:nn
- Set Channel Status Type
- ACK:
nn=00
- Send Consumer CS Data
nn=01
- Follow Input (or use last set)
nn=02
- Send Professional CS Data
DWN:
- Download new code
-OK: then erasing message
Then send S-records followed
by S-record terminator to force
programming of flash memory
and reboot
FPL:
- Request Front Panel Limits
- FPL:a_b
Where a = Lock Status (0=unlocked, 1=locked)
b = Master Frequency Limit (0=no limit, 1=48kHz, 2= 96kHz)
FPS:
- Request Front Panel Settings
- FPS:aa_bb_cc_dd_ee_ff
Where aa = value of Sync Mode as MOD: below
bb = value of Master Frequency as FRQ: below
cc = value of Sync Frequency as FRQ: below
dd = value of CS Data as CSD: above
ee = value of Input 1 Source Select as SS1: below
ff = value of Input 2 Source Select as SS2: below
FRQ:nn

LOC:
- Lock Front Panel
- ACK:
MEM:
- Memory Dump
- Memory, then 10 lines
Madd:data
Where add is memory address starting at 060(hex)
and data is 16 bytes of data, each byte shown as 2 hex digits
