SL&N?
Get active channel calculated from center frequency ( = (active frequency –
center frequency)/channel spacing )
Response: decimal number "+nnnn", "-nnnn", "+nn" or "-nn"
SL&W?
Get channel spacing/channel width
Response: "25.0 kHz", "12.5 kHz" or "20.0 kHz"
SL&W=xxxx
Set channel spacing. Value of xxxx is:
”1250” for 12,5 kHz
”2000” for 20 kHz
”2500” for 25 kHz
Command is supported only by hardware variants with adjustable channel
spacing
Before using this command, make sure that active frequency matches new
channel spacing
SL%F?
Get status of Error correction (FEC)
Response: "0" = FEC OFF or "1" = FEC ON
SL%F=x
Set Error correction (FEC). Value of x is:
"1" Set FEC ON
"0" Set FEC OFF
SL@C?
Get Call sign settings
Response: a,b,c followed by Carriage Return character, where:
a=CallSignState (0=OFF, 1=ON)
b=CallSignInterval (0...255) in minutes
c=CallSignId (max 16 alphanumeric characters)
Example: "1,5,MYMESSAGE" followed by CarriageReturn character
SL@C=a,b,c
Set Call sign settings.
a=CallSignState (0=OFF, 1=ON)
b=CallSignInterval (1…30) in minutes
c=CallSignId (max 16 alphanumeric characters)
SL@D?
Get Tx delay (ms)
Response: For example "0 ms" or "50 ms"
SL@D=n
Set Tx delay (ms), n is [0…65535]
SL@E?
Get supported radio compatibility modes.
Response: List of numbers, separated by commas, showing the supported modes:
0=Satel3AS, 1=PacCrest 4FSK, 2=PacCrest GMSK, 3=Trimtalk GMSK (RX fits
PacCrest modems), 4=TrimTalk GMSK (RX fits Trimble modems), 5=PacCrest-
FST
For example: "0,1" indicates that the modem supports Satel3AS and PacCrest
4FSK protocols.
SL@F?
Get noise level of radio channel
Response: "-xxx dBm"
SL@M?
Get repeater function
Response: "O" = Repeater OFF or "1" = Repeater ON
SL@M=x
