Protocols conversion

ASIU-E : COTS box qualified to be on-board, allow the conversion of several protocols such as ARINC 429/825/575/419, MIL-STD 1553, RS232, RS-422, CAN / AeroCAN, USB, Ethernet 10/100, torque conversion.

Mezzanine card slot for custom interfaces such as discrete I / O, analog I / O, communication interfaces, relay commands ..

ARINC 429 Isolator device


The ISO8-429-xx contains features to protect Arinc 429 Lines. Equipment under test could generate over voltage, transient signal or short circuit which could damage Arinc 429 boards channels installed in a Test bench. The ISO8-429-xx protects the test bench using galvanic isolation , transorbs, gas tubes and clamping diodes.
This device offers up to 8 lines, modulo 2 Rx or 2 Tx

Up to 4 piggy boards with 2Rx or 2Tx channels can be plugged on the carrier board proposing from 8RX/0TX to 0RX/8Tx with all the between configura-tion. The protection circuits are installed on the carrier, on the Equipment side.
