Large Network Support
WIT2450M2 modules transmit at an RF data rate of 460.8 kb/s using beacon-synchronized CSMA to support large point-to-multipoint (star)
network applications. Serial communications between a WIT2450M2 module and its host can run at up to 230.4 kb/s to further speed data
communication.
Reliable
WIT2450M2 modules provide both reliable communication and reliable operation. Using robust frequency hopping spread spectrum
technology, WIT2450M2 modules provide immunity to interference and multipath fading. Using a 24-bit CRC for error detection, automatic
retransmit request (ARQ) and a 3K data buffer, error-free transparent communication is automatic. Built-in data scrambling adds a
measure of security. Reliable operation is assured through RFM’s stringent QA processes. All WIT2450M2 modules are manufactured in
an ISO9000 certified facility.
Simple
Simple to integrate and use, the WIT2450M2’s default parameter settings work for most applications. For other applications, software
control makes changing parameter settings easy. The WIT2450M2, with its small size and low power consumption, is simple to integrate
into your product. The WIT2450M2’s RS-232 style interface with standard 3.3 volt CMOS signal levels makes integration easy. Since
WIT2450M2 modules are certified for license free operation in the USA, Canada and Europe, your WIT2450M2 based product does not
have to repeat radio regulatory approval.
Versatile
WIT2450M2 operating parameters are configurable under software control. Even the transmitter power level can be selected using a
straight- forward command set. Both point-to-point and point-to-multipoint modes are supported. Baud rates from 1.2 to 230.4 kb/s are
provided for serial communication between a WIT2450M2 and its host. Measuring just 69.85 x 47.75 x 4.57 mm and weighing 28 grams,
the WIT2450M2 can be integrated into fixed, portable or handheld devices with little impact on the size and weight.
