The PC104P-SI04BX board is a four channel serial interface card which provides high speed, full-duplex, multi-protocol serial capability for PC104+ applications. The SIO4BX combines two multi-protocol Dual Universal Serial Controllers (USC®), 8 external FIFOs, and multi-protocol transceivers to provide four fully independent asynchronous or synchronous serial channels.
Multi-protocol Transceivers support RS422 (V.11)/RS485, RS423 (V.10), RS232 (V.28), V.35, RS530, as well as other Mixed Protocol modes. These features, along with a high performance PC104+ interface engine, give the PC104P-SIO4BX unsurpassed performance in a serial interface card.
