The M4K708 module supports two ARINC 708/453 channels, each programmable as transmit or receive, which provides a complete solution for the development and testing of Weather Radar Display Databuses. Each channel implements a 64K x 16 FIFO and supports polling and/or interrupt driven operation. The M4K708 comes complete with C drivers including source code. In addition, Excalibur produces adapter cables that convert the carrier board I/O Molex™ connector to two twinax Trompeter CJ70 connectors (or equivalent). The cable may be purchased at an additional cost.
