Baud rate: 57600, 38400, 19200, or 9600
Protocol: Modbus RTU
Wiring: Single twisted shielded pair, 18 AWG. Wiring distance is
approximately 5,000 ft. (1,524 m)
Ethernet
10baseT/ 100base-TX Ethernet communication port,
Supports Modbus TCP/IP and OPC with 32 bit floating point
values. Scaled integers are supported with Modbus TCP/IP.
Modbus registers and OPC tags may be assigned to
measurement inputs from self-organizing network.
Assignment of tags include measurement values, status,
timestamp, alarm, and battery voltage of self-organizing
transmitters.
The configuration of the tags and monitoring is performed using
web pages generated by the 1420 Wireless Gateway.
AMS management of self-organizing network transmitters.

Remote Antenna Specifications
(1)
6 dB gain antenna, [length 11.5 in. (300 mm)] N type connector, for
use with up to 50 ft. (15,2 m) of LMR-400 coaxial cable.
Lightening Protection
50 Ohm Gastube type, bulkhead mount, weatherized, 0.5 dB
insertion loss.
(1) For remote antenna applications, the WL1 through WL4
options are required to maintain all applicable certifica-
tions, approvals, and network performance specifica-
tions. Increasing antenna gain or remote cable length
may result in loss of certification and/or network perfor-
mance.
