. Simple to use and simple to integrate, the
WIT2450 is a complete wireless data modem. All you need to do
is send data to the module through a standard asynchronous
serial interface. Error detection and correction is handled by the
WIT2450. The WIT2450 provides an addressing mode that allows
point-to-multipoint operation without having to sacrifice data
reliability or throughput. There is no need for your application to
know what the radio module is doing – you simply send and
receive data through a UART.

. The WIT2450 provides robust, reliable wireless
communications as well as reliable operation. With frequency
hopping spread spectrum radio technology and Cirronet's patent-
ed wireless MAC, the WIT2450 provides immunity to jamming
and multipath fading. Using a 24-bit CRC and automatic retrans-
mit request (ARQ) along with a 3K buffer, transparent, error-free
communications is automatic. Reliable operation over a -40 C to
+70 C operating temperature range is assured through our strin-
gent QA processes. All WIT2450 modules are produced in an
ISO9001:2000 certified facility to Cirronet's exacting standards.
Just another reason Cirronet is the choice of hundreds of design-
ers worldwide.

.While the factory-set parameters are suitable for
most applications, the WIT2450 provides the same degree of
configurability that has distinguished the WIT2410. Standard
and non-standard baud rates can be selected through a simple
command-driven configuration mode. Transmit power settings,
the speed at which the radio hops, 802.11b avoidance
frequency bands, and network IDs, among other settings, can
be set and saved in non-volatile memory for applications
requiring different operating characteristics. Point-to-point,
point-to-multipoint and store-and-forward repeating while
operating as a node are supported.
