• 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 +140 degF (-40 to 70 degC)

• EMC Compliant FCC Part 15 Class A

• Housing, extruded aluminum case 4.5”x 7.3”x 1.2”(114 x 185 x

30mm) DIN rail mounting, removable terminal blocks for

ease of module replacement, terminals suitable for 12 gauge

(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

• Frequency Hopping Spread Spectrum Transceiver

• Frequency - USA/Canada 902 - 928 MHz

- Australia 915 - 928 MHz

- NZ 921 - 928MHz

• Hop Sequence - 16 x 50

• Transmit Power 1W

• RSSI –120 to -60 dBm

• Expected line-of-sight range, depending on local conditions

- USA/Canada 20+ miles

- Australia/NZ 20+ km

• RF Data Transmission Rate - 19200 baud, 57600 baud, 115200

baud (selectable)

• Range may be extended by: - up to ve intermediate repeaters

in controlled mode - unlimited repeaters in transparent mode

• Conforms to FCC Part 15 Class A and FCC Part 15.247

• 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.
