The RX2M receiver and TX2M transmitter modules offer a low power, reliable data link in an industry-standard pin out and footprint. This makes the TX2M/RX2M pair ideally suited to those low power applications where existing wideband modules have insufficient range, or where multi-channel operation is needed.
Two versions are available, covering the 458.5-459.1MHz UK band (at 100mW) and the European 433.05-434.79MHz band.

• 433MHz version conforms to EN 300 220-3 and EN 301 489-3 and 458MHz version to MPT 1329 (UK specs)
• Any custom band between 420MHz and 480MHz with 5MHz (AR0) frequency range
• High performance double superhet, 128 channel PLL synthesizer with TCXO
• Data rates up to 5 kbps for standard module
• Usable range over 1km
• Fully screened. Low profile
• Feature-rich interface (RSSI, automatic noise squelch, analogue and digital baseband)
• Incorporate a 1200baud dumb modem
• Re-programmable via RS232 interface
• Low power requirements

• Handheld terminals
• EPOS equipment, barcode scanners
• Data loggers
• Industrial telemetry and telecommand
• In-building environmental monitoring and control
• High-end security and fire alarms
• Vehicle data up/download
