Power Supply

• 10 - 30 VDC or 10 - 24 VAC supply

• Normal current drain 70mA/12VDC or 50mA/24VDC

• Current when transmitting 350mA/12V or 250mA/ 24V

• Low power mode current drain 20mA/12VDC or 15mA/24VDC

General

• Environmental -40 to 60 degC, 0 to 99 %RH

• EMC Compliant ETS 300 683

• Housing, extruded aluminium case 114 x 185 x 30 mm DIN

rail mounting, removable terminal blocks for ease of module

replacement, terminals suitable for 2.5sqmm conductors.

• LED indication for unit OK, radio TX and RX, serial TX and RX,

DCD (comms OK).

Serial Port

• Standard data rates 1200 to 115200 baud.

• RS232 and RS485 standard interface connections provided,

each connected to the same serial port. Serial interfaces are

asynchronous non-return-zero (NRZ) format.

• Characters supported 7 or 8 data bits, even/odd/no parity,

1 or 2 stop bits

• RS232 connection provides full duplex operation as a DCE

device with RTS/CTS hardware handshaking- standard D9

connector.

• RS485 connection provides half duplex operation for twisted-

pair multidrop networks.

• Input and output buers 2Kbyte

Radio Transceiver

• Single channel, synthesised transceiver

• Frequency 869.4 - 869.65 MHz, 250KHz channel

• Transmit Power 500mW

• RSSI -60 to -120 dBm

• Expected line-of-sight range, 5 km at 19200 bits/sec

• RF Data Transmission Rate - 19200 baud, 38400 baud,

76800 baud

• Range may be extended by:-

- up to ve intermediate repeaters for controlled mode

- inlimited repeaters for transparent mode

• Conforms to EN 300 220

• Antenna connection is SMA coaxial

Data Transmission

• Transparent mode: Data is transmitted with a system and

group address. Data transmission begins as serial data is

received – maximum packet size is 530 bytes. All modules,

with correct system address, which receive the data packets,

outputs the data - error checking is optional.

• Controlled mode: Data is transmitted in packets with a

system address, source address, destination address, up to

ve intermediate repeater addresses, and a 16 bit CRC error

check. If the packet is received with a correct error check,

only the destination module will output the data and will

also return an ACK transmission.

If the source module does not receive the ACK, it will retry a

further four times. DCD provides communications status.

• Auto-connect and dial-up-control modes are available.

• CTS/RTS ow control provided based on input buer

availability.

Conguration and Diagnostics

AT commands. Radio noise, signal strength and bit error

rate (BER) diagnostics included. Radio signal strength value

available on-line to host device.
