AVIONICS COMMUNICATION BOARD EXC-1553P104/MCH The EXC-1553P104/MCH board is available with up to three channels, and all versions may be ordered in commercial or extended temperature grades. Each dual redundant channel may be programmed to operate as a Bus Controller, Remote Terminal, Bus Monitor or Remote Terminal/ Concurrent Bus Monitor. The board, when used in conjunction with a PC/104 based host, provides a compact yet sophisticated solution.
