Commands
Description
Note
SL#I=xxxx
Program all the addresses (TX/ RX) with value xxxx = hexadecimal
address (0000... FFFF)
SL@R?
Display the reception level of the latest received message.
Response: -xxx dBm with xxx decimal value
The RSSI values are between –115 and –60 dBm.
SL**>
Save the current configuration in EEPROM. Each time you switch on the
modem, the EEPROM configuration will be loaded in the modem registers.
SL%V?
Display the software version (response Vn.nn)
SLSn?
Reading the value of register n
SLSn=m
Initialise the register n with the value m (m=0000….FFFF)
SLR
All the registers are initialised with their default value
SLTn
auto-test mode (n = test number)
SLT1 = carrier emission, TX data = 0
SLT2 = carrier emission, TX data = 1
SLT3 = 19200 kHz modulation (38400 bauds)
SLT4 = 1 kHz modulation (2000 bauds)
Test mode exit : by updating the working mode (SLS220=x)
1
SLI
Display all the registers values
Note 1: During SLTn command transmission, the new working mode (S220 register) is
stored in E2PROM
Î
The modem will run again in auto-test mode at each power up.
To leave the auto-test mode, you have to modify the S220 register and save the parameters.
•
Description of the registers
The parameters of the modems could be updated through the SLS commands and save in
EEPROM.
When upgrading a register value, the value is updated in RAM. You must use the SL**>
command to save the parameters in EEPROM. In case of parameters lost, the default
values are restored.
