7.3 SL commands
If the SL-command function is activated radio channel and addresses can be changed directly from
the serial port of the radio data modem without connecting pin 12 to ground. SL commands should
be sent using the data speed and bit settings which are currently in use. However, the data part of
the character must be 8 bits.
The changes are made with a programming packet,
which is a
separate packet and may not be included in the transmitted data packet, and may not include extra
characters. The length of the programming packet should be 5 characters and the length of the
pause before and after the programming packet must exceed 3 characters.
7.3.1 Setting the addresses
All the four addresses (TX1, RX1, TX2, RX2) can be set simultaneously with the command
SLAxy
where x and y are characters consisting of 8 bits.
Programming both of the receiving addresses is possible with the command
SLRxy
and both of the transmitting addresses with the command
SLTxy.
After recognizing an address programming packet the radio modem disables the CTS signal and
sets the new addresses. If the setting is successfully completed the radio modem answers
OK
7.3.2 Setting the radio channel
The radio channel can be changed with the command
SLLxy
or
SLHxy
