WIT2410M4G
WIT2410S4G
FHSS
Transceiver
Modules
WIT2410 transceiver modules are designed to transmit serial data using highly robust 2.4 GHz
frequency hopping spread spectrum (FHSS) technology. WIT2410 modules employ Murata's
beacon-synchronized TDMA at an RF data rate of 460.8 kb/s to achieve very low transmission
latency. WIT2410 transceivers are suitable for both point-to-point and point-to-multipoint
networks. FHSS technology provides strong immunity to both interference and multipath fading.
The small size, light weight and low power consumption of these transceiver modules make them
suitable for a wide variety of applications. WIT2410 modules are certified for unlicensed
operation in the USA, Canada and Europe.

Fast
WIT2410 modules transmit at an RF data rate of 460.8 kb/s using beacon-synchronized TDMA to achieve very low transmission latency
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 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 Murata's stringent QA processes. All WIT2410 modules are
manufactured in an ISO9000 certified facility.
Simple
Simple to integrate and use, the WIT2410’s default parameter settings work for most applications. For other applications, 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 transmitter power level can be selected using a straightforward 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 weighing 35 grams, the WIT2410 can be integrated into fixed, portable or handheld devices with little impact 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.
