The modem converts data from a serial link into a radio frame to be sent to a similar piece
of equipment.
Serial link RS232 / RS485
radio transmission
The operating parameters of these modems (serial link, radio management….) can be
modified through commands on the serial link.
The products are available either in card version to be integrated in an assembly or as an
IP65 chip with integrated or external antenna (RG58C cable + TNC connector).

RS485 Network
The RS485 link needs to be adapted (each side). The modem includes a 100Ωtermination
resistor:
•Jumper mounted, the resistor is connected between A and B (respectively RX+ and RX-)
•No jumper, the resistor is not connected between A and B
If the modem is ending the RS485 bus, the jumper must be mounted.
The RS485 bus wiring needs only two wires for the PCB revision B (ARF7120/B) or
greater. For the PCB revision A (ARF7120/A), the TX+ (respectively TX-) and RX+
(respectively RX-) MUST be connected together by the USER.

The wiring could be checked by sending the SLI command using a terminal (see serial
command). If the link is properly configured, the modem register values are sent back by
the modem to the terminal (if not try to reverse the RS485 bus polarity Îreverse
RX+/TX+ with RX-/TX- connection).
•RS485 interface activation
When delivered the product is configured in RS232 Îfor ACTIVATING the RS485
interface, please refer to chapt. Configuration of the serial interface
WARNING: when using the RS485 interface, the minimum time for switching from
RS485 transmission to RS485 reception is 4 ms, 20 ms for baudrate 600 and 1200bps.

•RSSI reading
The RSSI (Received Strength Signal Indicator) gives an indication for the received power
level.
Power level
Notes:
•The RSSI level is only an indicator. Use this level with care due to the dispersion
between components.
•The schema above could be modified from one to another product. The Operating
temperature could also have an impact on these dispersions.
•The RSSI level could also indicate the potential presence of jammer in the used
channel.
•The RSSI is a necessary but not sufficient condition to obtain a correct reception.
RADIO COMMUNICATION

06-06-V6-smn p8
Half duplex transmission
This modem has 2 working modes:
¾Transparent mode, without flow control. When transmitting, data received from the
serial link are transmitted on the radio link. When data are received on the radio link,
these data are sent on the serial link.
¾Addressed mode, with flow control (see register S216)
In these modes, the frame transmission always start on the following conditions:
•Detection of a silence on the serial link, greater than S217, after the reception of the
latest character.
•Or when the number of received characters from the serial link is greater or equal to
the maximum radio frame size (S218).
•Addressed mode
In transmission mode, data received on the serial link are sent on the radio link with
the following format:
•Frame format: <preamble><synchro><Address> DATA <postambule>. Preamble,
synchronisation and postambule are used for the radio reception.
•The Address field is set up with S256 (destination address) value (LSB first).
In reception mode: The <Address> field of the radio frame is checked with the local
address (S252)
•If the addresses match, DATA (and only DATA) are transmitted on the serial link,
otherwise received data are silently discarded.
•Serial commands
¾They are used to configure the modem parameters or read the modem set-up.
¾They are sent during the modem mode. They aren’t sent on the radio link.
¾A SLSTRING is interpreted as a command only if a silence is present before (see
<silenced>) the SLSTRING and after (see <silencef>) the SLSTRING. Otherwise the
string is not interpreted as a command, and therefore it is sent on the radio link.
Serial Command format: <silenced>SLSTRING<silencef> with
•<silenced>: silence before the command, more than 3 characters (see S214).
•SLSTRING, serial command, always starting with the characters SL. (Example SLI
for displaying modem registers)
•<silencef> : end silence, more than 3 characters (see S214)
The answer to a SL command could be:
•the string OK Îcommand executed successfully
•The string ERROR (syntax error, unknown command…)
•a specific string according to the requested information

•Set of commands
Commands Description Note
SL#I=xxxx Program all the addresses (TX/ RX) with value xxxx = hexadecimal
address (0000... FFFF)
SL@R? Display the reception level of the latest received message.
Response: -xxx dBm with xxx decimal value
The RSSI values are between –115 and –60 dBm.
SL**> Save the current configuration in EEPROM. Each time you switch on the
modem, the EEPROM configuration will be loaded in the modem registers.
SL%V? Display the software version (response Vn.nn)
SLSn?
Reading the value of register n
SLSn=m
Initialise the register n with the value m (m=0000….FFFF)
SLR All the registers are initialised with their default value
SLTn auto-test mode (n = test number)
SLT1 = carrier emission, TX data = 0
SLT2 = carrier emission, TX data = 1
SLT3 = 19200 kHz modulation (38400 bauds)
SLT4 = 1 kHz modulation (2000 bauds)
Test mode exit : by updating the working mode (SLS220=x)
1
SLI Display all the registers values
Note 1: During SLTn command transmission, the new working mode (S220 register) is
stored in E2PROM ÎThe modem will run again in auto-test mode at each power up.
To leave the auto-test mode, you have to modify the S220 register and save the parameters.
•Description of the registers
The parameters of the modems could be updated through the SLS commands and save in
EEPROM.
When upgrading a register value, the value is updated in RAM. You must use the SL**>
command to save the parameters in EEPROM. In case of parameters lost, the default
values are restored.

R/W S252 Local Address 2 bytes value, from 0 to FFFF
In addressed mode, allow filtering the incoming radio
frame (all frame with an <address> field different from
this local address are silently discarded)
R/W S256 Destination Address 2 bytes value, from 0 to FFFF
In addressed mode, the <address> field of a radio frame
is filled with this destination address)
Note 1: when a serial speed change is requested, the S214 and S217 register values are
automatically set to a value greater or equal to the duration of three characters in the
requested speed (13 ms for 2400 bauds, 7 ms for 4800, 3 ms otherwise).
Note 2: 3 stop bits are only usable with 8 bits of data. With 7 bits of data and 3 stop bits,
the serial format used is 7 bits of data and 1 stop bit.
Note 3: When changing the interface type (example: RS232 to RS485), the response is sent
before the interface updates (in our example on the RS232 link); the following serial
communications must be done on the new interface (in our example, on the RS485 link).
