Resumen
The RF500M is a versatile radio modem for networks with UHF/VHF radios, typically serving as an interface between the data logger and radio. In addition to serving as a field modem connected to a data logger, the RF500M can also be used as a stand-alone repeater, or as a base-station modem connected to a computer. The RF500M is generally used with legacy or existing PakBus and mixed-array/dial-up networks. The RF500M works with our RF320-series radios, RF310-series radios, RF300-series radios, or any radio and modem combination that outputs a demodulated byte stream via RS-232.
For new installations, please consider one of our spread-spectrum radio solutions, or contact Campbell Scientific to discuss the use of other licensed radio options.
The RF500M is an appropriate choice for any ALERT(1) store-and-forward repeaters or base-station-decoder applications. For ALERT2 applications, refer to the ALERT200 ALERT2 Basic Remote Data Platform.

- Supports multiple radio configurations
- Uses software (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

Descripción detallada
The RF500M serves as a remote, repeater, and 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.
-PB Operating System
The RF500M's -PB operating system was designed to quickly and efficiently move data through a network, making it a perfect choice for large networks or networks requiring fast collection intervals.
The time division polling (TD-RF) nature of the network provides collision free communications as the base modem controls when and how all data moves. An area wide poll releases station-originated data, with each station having its own dynamically allocated slot in which to transmit. The data is collected and moved through the network back to the base. Two-way communications allow each station to be remotely administered (send program, change variables, etc.) from the base. Station-to-station communications are possible using PakBus; however communications occur on the poll and must be routed though the LoggerNet server.
-DA Operating System
The -DA operating system enables each station to be dialled from anywhere in the network, at any time. This ability supports masterless point-to-point communications.
-AL Operating System
The ALERT (Automated Local Evaluation in Real Time) operating system (OS) allows for transmission, repeating, and reception of binary ALERT formatted data. Additionally, it is a derivative of the -PB OS, and therefore supports both ALERT and TDRF communications (allowing true two-way communication with a station).
When used as an ALERT transmitter, the RF500M accepts an array of ALERT ID/Value pairs allowing multipacket transmissions. It can also turn any station into a store-and-forward ALERT repeater with programmable pass/reject lists. With the ability to transmit, receive, decode, and repeat ALERT data, the RF500M and datalogger allow for the creation of standard and advanced ALERT network components including:
- Transmitters
- Repeaters with sensor inputs
- Store-and-forward repeaters
- Multifrequency repeaters
- Data concentrators
- Robust high traffic base stations

-
Yes. When the RF500M is powered up (or whenever the internal processor is reset), each of the LED indicators on the modem will illuminate, cycle through a series of colors, and turn off. This is an indication that the RF500M is running the Power On Self-Test (POST). If the LEDs remain illuminated, this is an indication that the POST has failed.
-
The RF500M Radio Modem is warranted by Campbell Scientific, Inc., to be free from defects in materials and workmanship under normal use and service for twelve (12) months from date of shipment unless specified otherwise.
-
No. The RF500M cannot be directly interfaced with a GPS receiver. However, most Campbell Scientific dataloggers can be interfaced with the output from a GPS receiver and programmed to extract the positional information. This information can then be accessed via an RF500M/RF320 RF link.
-
Usually, yes. Contact Campbell Scientific for a return material authorization number (RMA) and instructions for returning the unit for repair. Additional information is available on the Repair and Calibration page.
-
Engineering drawings, in general, are not made accessible to the public. For a specific question, contact Campbell Scientific for assistance.
-
No. The CR1000KD is designed specifically for use on the CS I/O port of the CR800, CR1000, and CR6 dataloggers.
-
If the RF modem has a CS I/O connector, then it should be compatible with the CR10X without the use of an SC932A. Ensure that the RF modem’s firmware is compatible with the CR10X firmware.
Note: RF modems that are not sold by Campbell Scientific will only interface with a CR10X via an SC932A or an SC105.

Data Logger Considerations
Time division polling and PakBus communications can be used in the same network as long as all of the data loggers are PakBus versions.

Notes:
#The RF500M cannot be a repeater while the modem is connected to a CR200(X) or CR300-series datalogger.
**The RF500M is only compatible with the CR6 when using -PB OS version 3 or later.
‡The -PB OS option for the RF500M is only compatible with the -PB and -TD OS for the CR510, CR10X, and CR23X.
♣The -DA OS option for the RF500M is NOT compatible with the -TD OS option for the CR510, CR10X, and CR23X.
Radios
Three jumper settings allow the RF500M to be used with a variety of radios. Though not a requirement, it is a good idea to standardize your network to use a single radio type. This practice simplifies operations and maintenance and provides the highest degree of interstation compatibility possible.
