Aitech M705 - MIL-STD-1553B Multi I/O Communications PMC

Provides Multiple Avionics Style Communication Protocols (MILSTD-1553, ARINC-429 and Serial I/O).


The M705 Multi-I/O Communications PMC provides multiple avionics style communication protocols (MILSTD-1553, ARINC-429 and Serial I/O), all packed into a small single-width PMC form factor specifically designed for harsh environments. It offers a complete and unique solution for applications requiring diverse multiple avionics communication ports, eliminating the need for multiple cards and providing high flexibility for system integrators. The M705 integrates 5 dual redundant MIL-STD-1553 channels, 16 ARINC-429 receive channels, 8 ARINC-429 transmit channels, and up to 6 UART ports.

MIL-STD-1553B ports support BC/RT/MT operation modes, Serial ports support RS-422/RS-232/RS-485 physical layer. 3 of the 6 serial ports can be configured to provide modem hardware flow control (flow control signals support RS-232 only). The M705 also features 8 opto-isolated digital discrete input channels, which may be used to externally assign a unique RT address to one of the MIL-STD-1553B ports.

M705 I/O signals can be routed to either the P4 or front panel connectors, according to the configuration.
