The BU-65590C is a multi-protocol PC/104-Plus card that provides flexibility for systems interfacing to a MIL-STD-1553 or ARINC 429 data bus. There are up to 2 dual redundant MIL-STD-1553 channels operating in BC, RT, MT, or combined RT/MT modes. Sixteen ARINC 429 receive and eight ARINC 429 transmit channels operate in high/low speed with automatic slew rate adjustment. The card also contains up to nine digital discrete I/O, eight +35V Avionics Discrete I/O, an IRIG-B time code input, an IRIG-B time code generator, a clock time stamp input and a clock output. The combination of multiple I/Os on one card saves valuable PC/104-Plus space, shortening the height of the stack to fit inside of small spaces. Additionally available in PCI-104 format (BU-65591C)
