WIT2450 Low-Cost Frequency Hopping Transceiver OEM Module From the leader in robust, high-performance wireless modules comes the next generation of low-cost 2.4GHz spread spectrum OEM modules. The Cirronet WIT2450 provides the unique combination of highly integrated low-cost components and the high performance, high-reliability RF know-how that has made Cirronet products the first choice of designers for mission critical applications, at a price that allows use in a wide variety of cost-sensitive applications. Simple. Simple to use and simple to integrate, the Just another reason Cirronet is the choice of hundreds of design- WIT2450 is a complete wireless data modem. All you need to do ers worldwide. is send data to the module through a standard asynchronous Flexible. While the factory-set parameters are suitable for serial interface. Error detection and correction is handled by the WIT2450. The WIT2450 provides an addressing mode that allows most applications, the WIT2450 provides the same degree of point-to-multipoint operation without having to sacrifice data configurability that has distinguished the WIT2410. Standard reliability or throughput. There is no need for your application to and non-standard baud rates can be selected through a simple know what the radio module is doing - you simply send and command-driven configuration mode. Transmit power settings, receive data through a UART. the speed at which the radio hops, 802.11b avoidance frequency bands, and network IDs, among other settings, can Reliable. The WIT2450 provides robust, reliable wireless be set and saved in non-volatile memory for applications communications as well as reliable operation. With frequency requiring different operating characteristics. Point-to-point, hopping spread spectrum radio technology and Cirronet's patent- point-to-multipoint and store-and-forward repeating while ed wireless MAC, the WIT2450 provides immunity to jamming operating as a node are supported. and multipath fading. Using a 24-bit CRC and automatic retransmit request (ARQ) along with a 3K buffer, transparent, error-free communications is automatic. Reliable operation over a -40 C to Let us be your experts.
