AS 11 - Data Transmitter and Decoder

The device is used to bidirectional data transfer between RS422 and RS232 line and to convert the incoming data from the RS422 line to the discrete outputs. The device also contains 4 currently unused digital inputs.

Typical application
AS11 can be connected to Avionics-grade Mission Display Unit MDU - 268. Device receives data for communication with external keyboard via RS422. Depending on the received data are switched the relay outputs.
