UT20 and UT30 Tower-based Weather Stations
8.3.5 RF500M RF Modem and RF310-Series Transceivers
Radiotelemetry (RF) enables communications between one or more
dataloggers and the computer over an FCC-assigned radio frequency in the
VHF or UHF band. The maximum distance between any two communicating
stations is approximately 20 miles and must be line-of-sight. Longer distances
and rough terrain may require intermediate repeater station(s). Refer to the
Radiotelemetry Network Applications manual for RF repeater stations and RF
Networks accessed remotely by phone.
8.3.5.1 RF500M Modem Configuration
Device Configuration Utility (DevConfig) software is used to configure the
RF500M modem. DevConfig is included with LoggerNet or it can be
downloaded for free from the Campbell Scientific web site
( www.campbellsci.com ). The configuration options can be seen in the
following figure:
To configure the RF500M, apply power to the modem, wait for the power-up
sequence lights to cycle and then turn off, connect the PC to the RF500M RS-
232 port with a null modem cable, open DevConfig, highlight the RF500M
option in the Device Type list, and click Connect. Press the green
configuration button on the RF500M either before or while connected to enable
the settings in DevConfig.
