Overview
Benefits and Features
The RF500M serves as a field, repeater, or base station communication interface, generally for our licensed radio applications. It
provides an interface between a datalogger or computer and a radio 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 configurable,
and has been designed to interface with data telemetry radios
such as our RF320-, RF310-, and RF300-series VHF/UHF radios.
Supports multiple radio configurations including our RF320series, our RF310-series, our RF300-series, and the DataRadio
DL-3400 radio
Uses software (i.e., DevConfig) instead of hardware modifications to upgrade the operating system (OS) and change RF ID
or other settings
Provides an RS-232 port (DTE) for modem configuration or attachment of an RS-232 radio
Avoids all collisions within a network, thus increasing polling
speeds and reducing overall current drain

Base Station (Office)
Our RF networks require line-of-sight transmission. The mountain in this drawing obstructs line-of-sight with the base station. Use of the repeater station allows the base station to receive data from the field stations.

Operating System (OS) Options Descriptions
Ordering Information
PakBus OS
Radio Modem
Must choose an OS option and a radio jumper setting option (see below).
RF500M
Radio Modem.
OS Options (see discussion at right)
-PB
PakBus OS.
-AL
ALERT Dual Mode OS.
-DA
Dial OS.
ALERT Dual Mode OS
The ALERT (Automated Local Evaluation in Real Time) OS allows
for transmission, repeating, and reception of binary ALERT formatted data. It is a derivative of the -PB OS, and therefore supports
both ALERT and TDRF communications (allowing true two-way
communication with a station). This OS is compatible with the
CR200(X)-series, CR800-series, CR1000, and CR3000 dataloggers.
Radio Jumper Setting Options
-MJ
Jumper for RF320-series or RF310-series radios.
-RJ
Jumper for RF300-series radios.
-UJ
Jumper for radios purchased directly from DRL.
Dial OS
Temperature Range Options
-ST
Standard -25° to +50°C (default).
-XT
Extended -55° to +85°C.
The dial OS works with both mixed-array and PakBus/table-based
dataloggers. Each station can be dialed by LoggerNet for downloading data, sending programs, and performing other tasks. Additionally, this OS allows stations to create point-to-point networks
for sharing of measurement and control tasks.
Warranty Length Options
-SW
Standard one year warranty (default).
-XW
Four year warranty extension.
Considered the standard for the RF500M, the -PB OS uses TDRF polling to quickly and efficiently move data through a network. Each
station can be individually dialed by LoggerNet. This OS is compatible with -TD, -PB, and our current generation of PakBus dataloggers.
Accessories
10873
9-pin female to 9-pin male serial data cable (6 ft); cable is
required to connect RS-232 digital radios.
SC532A
CS I/O Peripheral to RS-232 Interface; this interface is required
to connect a PC to the modem’s CS I/O port. Typically the PC
connects to the modem’s RS-232 port, but the modem’s CS I/O
port can be used if a digital radio is already connected to the
modem’s RS-232 port.
15966
Wall Charger 12 Vdc, 800 mA Output, 100 to 240 Vac, 50 to 60 Hz
with Barrel Plug, 6 ft Cable.
14291
Field Power Cable 12 Vdc Plug to Pigtail (2 ft ) connects with a
12 Vdc power supply.
14020
Field Power Cable CS I/O to 12 Vdc Barrel Plug (2 ft) connects
with datalogger.
At the field station, the
RF500M modem functions
as a communication interface between the datalogger and radio. Field stations
are located at the measurement site. This field station
uses a Yagi antenna to
transmit the data.

(weather stations)
Voltage: 7 to 20 Vdc
Dimension: 160 x 95 x 22 mm (6.31 x 3.69 x 0.88 in.)
Weight: 0.18 kg (0.4 lb)
Current Drain
▶
Active: <15 mA
Quiescent: <350 μA
The RF500M can be used as a
stand-alone repeater. Repeater
stations provide a communication relay between stations
that cannot communicate
directly due to distance or obstacles. Repeater stations use
omnidirectional antennas.
