WIT2410 transceiver modules are designed to transmit serial data using highly robust 2.4 GHz

frequency hopping spread spectrum (FHSS) technology. WIT2410 modules employ RFM’s

beacon-synchronized TDMA at an RF data rate of 460.8 kb/s to achieve very low transmission

latency. WIT2410 tran sceivers are suitab le for both point-to-point and point-to-multipoi nt networks.

FHSS technology provides strong immunity to both interference and multipath fading. The small

size, light weight and low power consumption of these transcei ver modules make them suit able for

a wide va riety of applica tions. WIT2410 module s are certified for un licensed ope ration in the USA,

Canada a nd Europe.

Fast

WIT2410 m odu les transmit at an RF data rate of 460 .8 k b/s usi ng be ac on- sy nc hron iz ed TDM A to ac hie ve very low tra ns miss ion late ncy

in point-to-point cable replacement applications or point-to-multipoint (star) network applications. Serial communications between a

WIT2410 module and its host can run at up to 230.4 kb/s to further speed data communication.

Reliable

WIT2410 modules provide both reliable communication and reliable operation. Using highly robust frequency hopping spread spectrum

technology, WIT2410 modules provide strong immunity to interference and multipath fading. Using a 24-bit CRC for error detection,

automatic retransmit r equest (ARQ) and a 3K data buffer , error-free transp arent commun ication is automatic. Built-in data scram bling adds

a measure of security. Reliable operation is assured through RFM’s stringent QA processes. All WIT2410 modules are manufactured in

an ISO9000 ce rtifi ed fac ili ty.

Simple

Simple to integrat e and us e, the WIT2 410’ s default par ameter setti ngs work f or most a pplicati ons. For o ther appl ications , software control

makes changing parameter settings easy. The WIT2410, with its small size and low power consumption, is simple to integrate into your

product. The WIT2410’s RS-232 style interface with standard 3.3 volt CMOS signal levels makes integration easy. Since WIT2410

modules are certified for license free operation in the USA, Canada and Europe, your WIT2410 based product does not have to repeat

radio regulatory approval.

Versatile

WIT2410 operating parameters are configurable under software control. Even the transmi tter 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 WIT2410 and its host. A number of non-standard baud rates are supported as well. Measuring just

80.2 x 46.5 x 8.6 mm and weighi ng 35 grams, the WIT2410 can be integrat ed into fixed, portabl e or handheld de vices with little im pact on

the size and weight. The low 3.3 volt operating voltage and 22 mA standby current makes the WIT2410 well suited to battery operation.
