Shown with shield removed

WIT2450M2 lo w-cost transceiver modules are designed to transmit serial data using robust

2.4 GHz frequency hopping spread spectrum (FHSS) technology. WIT2450M2 modules

employ Murata’s beacon-synchronized CSMA at an RF data rate of 460.8 kb/s to support a

large number of remotes. WIT2450M2 transceivers are suitable for both point-to-point and

point-to-multipoint networks. FHSS technology provides immunity to both interference and

multipath fading. The small size and light weight of these transceiver modules make them

suitable for a variety of applications. WIT2450M2 modules are certified for unlicensed

operation in the USA, Canada and Europe.

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 application s. Serial communicat ions between a WIT2450 M2 module and it s host can run at up to 230. 4 kb/s to furthe r speed da ta

communication.

Reliable

WIT2450M2 modules provide both reliable communic ation and reliable operation. Using robust frequency hopping spread spectrum

technology , WIT2450M2 modules provide immunity to interference and multipa th fading. Using a 24-bit CRC for e rror detection, automatic

retransmit request (ARQ) and a 3K data buffer, error-free transparent communication is automatic. Built-in data scramb ling adds a

measure of secu rity. Reliabl e operat ion is a ssured thro ugh R FM’ s stri ngent QA processe s. All WIT245 0M2 modu les are manufa ctured in

an ISO9000 ce rtifi ed fac ili ty.

Simple

Simple to integrate and use, the WIT2450M2’s default parameter settings work for most applications. For other applications, software

control makes cha ngi ng p ara meter settings easy. The WIT2450 M2 , w it h i t s small size an d low power con su mp tio n, i s sim pl e 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
