3 CHANGING PARAMETERS USING SL-COMMANDS

The controlling terminal device can change the configuration settings of the module. This is

accomplished with the help of SL-commands, which can be used during data transfer. SL-

commands can be used to change e.g. the frequency or addresses. It is also possible to ask the

radio modem to show current settings which are in use. The terminal device is either a PC or a

programmable logic (PLC) together with suitable (terminal) program.

3.1 SL-Commands

An SL-command is a continuous string of characters, which is separated from other data by

pauses which are equal or greater than time defined by Pause length parameter (default=3

characters) in the set-up. No extra characters are allowed at the end of an SL-command.

Serial interface settings are the same as in data transfer. SL-command is properly recognised

also in the case when the command string is terminated in <CR> (=ASCII character no. 13,

Carriage Return, 0x0d) or <CR><LF> (<LF> = ASCII char. no. 10, Line Feed, 0x0a). If

multiple SL commands are sent to the module, the next command can be given after receiving

the response ("Ok" or "Error") of the proceeding command. In addition, it is recommended to

implement a timeout to the terminal software for recovering the case when no response is

received from the radio modem.

The module will acknowledge all commands by returning an "OK" (command carried out or

accepted) or the requested value, or an "ERROR" (command not carried out or interpreted as

erroneous) message.

The SL-commands are listed in separate excel-document.

3.2 Operating modes

The modem has the following modes of operation:

Mode

Function

Description

Ready to

receive from RF

Search for sync

Module is searching for the start of a radio

transmission from the RF signal.

Receive data

The module has found a valid radio transmission

and is receiving data.

Safe mode

Mode is entered when a fault has been detected

and the device has been Rebooted. In safe mode

fault codes can be read from the modem.

Powersave

Sleep1

Will turn the modem into a state where it will hold

parts of the radio on, wakeup will take <5ms

Powersave

Sleep2

Will turn off the entire radio section and put CPU

into sleep mode. Consumption is lower, but

wakeup time is approx. <40ms.
