Repeater Station
Our RF networks require line-of-sight transmission. The mountain in this drawing obstructs line-of-sight with the base station. Use of the re-
peater station allows the base station to receive data from the eld stations.
Benets and Features
Supports multiple radio congurations including our RF320-
series, our RF310-series, our RF300-series, and the DataRadio
DL-3400 radio
Uses software (i.e., DevCong) instead of hardware modica-
tions to upgrade the operating system (OS) and change RF ID
or other settings
Provides an RS-232 port (DTE) for modem conguration or at-
tachment of an RS-232 radio
Avoids all collisions within a network, thus increasing polling
speeds and reducing overall current drain
Overview
The RF500M serves as a eld, repeater, or base station commu-
nication interface, generally for our licensed radio applications. It
provides an interface between a datalogger or computer and a ra-
dio and can be a stand-alone repeater when onsite logging is not
required. The RF500M is powered from the CS I/O port or from an
external power connection. This modem is software congurable,
and has been designed to interface with data telemetry radios
such as our RF320-, RF310-, and RF300-series VHF/UHF radios.
