Forming of the SL Command
By programming the radio modem with the SL command, please note that the form of the
address is different than in the SETUP MODE. In PROGRAMMING MODE the address is given in
hexadecimal (values between 0000 and FFFF) e.g. 2BFAh. By programming the radio modem
with SL command the address consists of an address of two 8 bit characters.
The radio modem requires the SL command as a continous packet. Either a file needs to be
created for the command or the application software designed for the radio modem must take
care of the continous transmission of the command. If there is a break in the transmission the
radio modem interprets the packets as transmitted data.
Forming of the programming packet of the address
If you want to use e.g. address 2B5A hex start by converting the hex value to characters.
This can be done by using a map of characters to convert the numbers (Appendix1). The
following character map is for character set PC-8. In case you have another character set in your
computer you must use a different character map or use methods given in Example 2.
Example 1
Hex. address
characters
SL -packet
2B5A
'+Z'
'SLA+Z'
Create a file needed for the SL packet and name it e.g. AD_2B5A.TXT. The first line of your file
would be :
SLA
+Z
You are now able to change the address of the radio modem. Copy AD_2B5A.TXT file to the
serial port. Note the settings of the serial port and the radio modem (see DOS
mode
command):
copy AD_2B5A.TXT com1
The file can be sent by using ASCII file transfer in the communications software.
As some of the characters are used for controlling devices, there is no key for them in your
keyboard. It is preferable to use the following method if you are not familiar with the character
set you are using.
