The M8K708 module is an ARINC-708 / 453 2-channel test and simulation module for the Weather Radar Display Databus. The M8K708 supports two ARINC-708 / 453 channels, each selectable as transmit or receive. Each channel implements an 64K×16 FIFO and supports polling and/or interrupt driven operation.

The M8K708 comes complete with Windows software, a C-driver software library including source code and may be used with Exalt, Excalibur’s Analysis and Laboratory Tools, a Windows monitoring application. In addition, Excalibur produces adapter cables that convert the carrier board I/O Molex™ connector to two twinax CJ70-49 connectors. The cable may be purchased at an additional cost.
