PC4/T2/R2, 2Tx / 2Rx ARINC 429 Interface Card

The PC4/T2/R2 ARINC 429 Interface card is a one third length PC ISA interface card comprising of two independent transmitters, two independent receivers, one microprocessor, on board Time Tag Generation, 28 volt Event input, Real Time Data Acquisition FIFO's, and Dual Port memory. 
The Dual Port RAM is the common interface between the PC Bus and the PC Card. 
The receivers perform on card filtering by Label (TAG) in Octal and SDI. The receivers independently adapt to the Bus Data rates that they are connected to. 
This information is also available to the operator.
