1 Technical description of the radio modem AMB8350
With the design of the new data radio modem AMB8350 we are continuing on the consistent
path of implementing customer wishes and using new, powerful processors. New functions
have been integrated in the AMB8350, which simplify the connection to existing systems. The
radio modem AMB8350 is compatible with OPC1426 and is consequently both a complement
and replacement. Compared to the previous model important RF characteristics like large
signal resistance, channel selection and receiver sensitivity have been considerably improved.
It is distinguished by its small, compact design and the combination of radio module and
transmission software. The unit consists of a FM synthesizer-transceiver, which operates in the
frequency band 868MHz and a controller unit with RS232 port. Connection to an RS232 port
and setting up a data radio transmission can be done quickly.
The module has a command set of various transmission modes, which can be individually
adapted to the application as required.
•addressed point to point or point to multi-point transmission with acknowledge
•unaddressed, unsecured transparent transmission (broadcast)
•addressed transmission without acknowledge with CRC check and/or ETX
The parameter assignment of the radio module occurs via the serial RS232 port. Two
possibilities are available as user interface:
•configuration program “AMBER wireless Config Center” (ACC)
•terminal program e. g. “HyperTerminal“ using AT commands
Thanks to its module character, the AMB8350 can be integrated without great effort in already
existing devices or systems and can be directly employed by the user on account of its general
authorisation. The 868 MHz band is a frequency band authorised across Europe.
Characteristics
•Receiver sensitivity typically of -108dBm
•Transmitting power typically 13dBm = 20mW
•Range up to 1,000m with clear visibility and corresponding antenna positioning
•Bit transparent transmission without instruction level (cable replacement!)
•Different transmission modes (broadcast, transmission protocol)
•Individual addressing of an AMB8350
•Complete RS 232 interface according to V.24 standard
•Serial data rates of 110 to 115.200 baud configurable
•RF data rate 10 or 57.6kbps configurable
•Data security through CCITT 16 bit check sum protection of the transmitted data
•Parameter assignment via RS232 with Windows configuration software or AT
instructions
•Possibility of firmware updates via RS232 with the help of ACC
•Voltage supply 4.0V – 10V
•Small dimensions and modular design of the device
•Europe-wide use not subject to registration

2.3.2 Pin connection of external LEDs
The LED signals are located additionally on the multi-point connector ST4 so that, for instance,
LEDs can be externally mountable. If external LEDs are used, the LEDs on the AMB8350 must
be switched off to avoid overloading the ports of the controller. To switch off the LEDs the
solder bridge SJ1 (see illustration above) must be removed. The series resistors of the LEDs
are already on the mainboard, so that external LEDs without series resistors can be used. The
value of the series resistors on the mainboard is 330 Ohm, which means given an LED voltage
of, for instance 1.6V, approximately 5 mA would flow through the LED.

2.6 Transmission Range and improvement
The 868MHz radio modem consists of a high performance transmitter and a receiver with high
sensitivity. Based on that parameters ranges of more than 1.000m at free line of sight and
optimal environmental conditions.
To realise the optimal and best range following point should be considered:
•at the antenna base a groundplane must be
•Hold large distance to ground as possible ( > 1m)
•Place both antennas with vertically alignment (polarisation)
•Antennas keep free of metal spacious
•Devices should not carry directly at the body
2.7 Note on operation of the modules
The interface parameters required for the system must be determined so that the data radio
functions with the user system. If applicable, these must be configured in the data radio
module. In the event of differing interface settings, no operation is possible or illegible
characters are transmitted. Two possibilities are offered for the configuration of the module via
RS232:
1. AT instruction set with a terminal program (chapter 3)
see also external document “Hyperterminal_HB” (short description)
2. “AMBER wireless Config Center” Windows-Tool ACC (chapter 4)
see also external document “ACC_HB”
In handling the module the ESD regulations must at all costs be observed to avoid
damage through static discharge!

AMB8350 Manual V1.2 Page 9 of 21 As of: 9.2.2007
3 Configuration with AT instructions
The data radio modem can be configured with a PC via the AT instruction set. The parameter
assignment occurs via RS232. A terminal program (e.g. Hyperterminal) allows communication
with the module. For this the correct interface parameters in the terminal program are a
precondition. The data format, the data rate and the handshake must be set as in the AMB8350
(on this see the external short description “Hyperterminal_HB”).
The AT commands will only be correctly understood if the setting is the same and only
then will a correct data transmission be possible.
For this reason we recommend making a note of the parameter settings every month. In
this way subsequent interface adjustment and correct communication with the modem
can be set up and carried out quickly.
3.1 Switch to the instruction level
The switch from the data mode to the instruction mode occurs via an escape sequence.
The ASCII character “+” (decimal 43) has been set as standard escape character. The escape
character can be set via the instruction “ATS5=x”.
Switch to the instruction mode:
1. 0.5 second waiting time before entry of the escape character
2. Enter the escape character 3x within 1 second
3. 0.5 second waiting time after entry of escape character
4. If the switch to the instruction mode was successful, the modem will report with “OK”
After the soft- or hardware reset the AMB8350 is once again in transmission mode.
Without reset the return to the transmission mode occurs via the instruction ‘ATO’.

AMB8350 Manual V1.2 Page 10 of 21 As of: 9.2.2007
3.2 AT instruction set
3.2.1 General
• The data radio device must be connected to a free COM port on the PC
• The instruction input occurs with the help of a terminal program e.g. Hyperterminal (see
short external description “Hyperterminal_HB”)
• On starting up the data radio module the terminal session must be configured with the
interface parameters 9,600bps, 8n1, without handshake (default)
• Instruction lines must always begin with AT (ATtention)
• The instruction input can occur in capitals or lower case letters
• The instruction input must be concluded with a CR (Return – except ESC sequence)
• On the instruction level a character echo is always returned to the RS232
Important:
Non-volatile storage of configuration settings in the module only occurs with the instruction
“AT&W” and as a rule only takes effect after a reset (power up or soft reset “atz”). In the case of
operating time parameters, it already takes effect before storage and reset (see respective notes).
3.2.2 AT instructions
Command Description Permissible values Example
Cx Set communication channel (0-40) ATC35
The setting of the communication channel occurs with this command.
Important: Before changing the channel please
consult chapter 2.5.3 “Channel frequency and use table”
Note:
•The setting will take effect at the next transition to radio operation (ato)
•The setting will be permanently stored only upon the instruction “AT&W”
