The RPM3 UHF Radio Packet Modem from Radiometrix is an intelligent wireless serial cable replacement that enables a two-way radio data link to be simply and quickly implemented between a number of serial devices at baud rates from 600 bps to 115,2 Kbps.
It is particularly useful for OEMs who require operation at both the 869,85 MHz (European), and 914,50 MHz (North American) frequency options, says Radiometrix.
The European version conforms to the ETSI EN 300 220-3, and EN 301 489-3 enabling manufacturers to get CE certification easily for their finished product. US version, RPM3-914-17-ANT, with integrated antenna is FCC certified. The modules ensure that data integrity is maintained by using an addressable data packeting mechanism, with error checking, packet acknowledgement and retransmission. In this way, says the manufacturer, a reliable, transparent, wireless data link with 100% duty cycle over a usable range up to 200 m is achieved with ease.
The compact module (which measures just 39 x 23 x 10 mm) is a self-contained radio modem module that requires only a simple antenna, 5/3 V supply, and a serial I/O port (UART) on a host microcontroller or PC. Designed for ease of use and rapid installation, the modem has many advanced in-built features which enable point-to-point, point-to-multipoint and broadcast mode networks to be established.
Possible applications include telemetry/telecontrol, ePOS equipment, barcode scanners, belt clip printers, stock control, job allocation systems, and remote data acquisition/data loggers. In-building environmental monitoring and control systems can also benefit from its features.
