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 ash 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_
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
 = value of Input 2 Source Select as SS2: below
FRQ:nn - Set Master Clock Frequency - ACK:
nn=00 - Select 32kHz Master Clock Sample Rate
nn=01 - Select 44kHz Master Clock Sample Rate
nn=02 - Select 48kHz Master Clock Sample Rate
nn=03 - Select 88kHz Master Clock Sample Rate
nn=04 - Select 96kHz Master Clock Sample Rate
nn=05 - Select 176kHz Master Clock Sample Rate
nn=06 - Select 192kHz Master Clock Sample Rate
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
