In case you need more information on the time delays related to the use of SL-commands, 
please contact the manufacturer.  

9.3.1 Frequency

Command  

Effect and description of command 

SL&F=nnn.nnnnn  Set frequency to nnn.nnnnn MHz 

SL&F? 

Display current frequency (response 'nnn.nnnnn MHz') 

SL&C? 

Display center frequency (response 'nnn.nnnnn MHz') 

SL&+=nn 

Set frequency nn channels above center frequency 
Frequency = Center fre nn * Channel spacing, where nn=[0...Number 
of channels/2] 

SL&-=nn 

Set frequency nn channels below center frequency 
Frequency = Center frequency – nn * Channel spacing, where nn=[0…Number 
of channels/2] 

SL&N? 

Display current frequency deviation from center frequency as channels  
(Frequency – Center frequency)/Channel spacing (response ‘+nn’ or ‘-nn’) 

SL&D=x 

Sets the operational mode of the radio. The different values of x are: 
”S” = Single Channel 
”D” = Dual Channel 
”R” = Reverse Dual Channel 
Note! Use this command only, if the setup of the frequency bands matches the 
Dual Channel operation. 

SL&D? 

Request the  operational mode of the radio. The response is one of the 
following: 
”S” = Single Channel 
”D” = Dual Channel 
”R” = Reverse Dual Channel 
Note! Use this command only, if the setup of the frequency bands matches the 
Dual Channel operation. 

9.3.2 Addressing

Command  

Effect and description of command 

SL#I=xxxx 

Set all addresses (RX1, RX2, TX1, TX2) to value xxxx 

SL#I? 

Display both primary addresses (TX1, RX1) (response ’xxxx;yyyy’) 

SL#T=xxxx 

Set both transmit addresses (TX1, TX2) to value xxxx 

SL#T? 

Display primary transmit address (TX1) (response ‘xxxx’) 

SL#R=xxxx 

Set both receive addresses (RX1, RX2) to value xxxx 

SL#R? 

Display primary receive address (RX1) (response ‘xxxx’) 

SL#P=xxxx;yyyy 

Set primary transmit address (TX1) to value xxxx and receive address (RX1) to 
value yyyy
