8 Forming the SL Commands
When programming the radio modem with SL commands, please note that the form of the
addresses is different than in the Programming Mode. In Programming Mode an address is given in
hexadecimal (values between 0000 and FFFF) e.g. 2BFAh. SL commands accept the address as two
8 bit binary characters.
SL commands must be sent as a continuous 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
continuous transmission of the command. If there is a break in the transmission, the radio modem
interprets the packets as transmitted data.
The easiest way to send SL commands is to use SaTerm, as it allows any binary character to be sent
using the Transmit window. See SaTerm documentation for details.
8.1 Forming a packet to change addresses
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 the 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 also 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.
