CHAPTER 1: INTRODUCTION
1.0 General Description
The PC104P-SI04BX/PCI104-SIO4BX board is a four channel serial interface card which provides high speed, full-
duplex, multi-protocol serial capability for PC104P applications. The SIO4BX combines two multi-protocol Dual
Universal Serial Controllers (USC®), 8 external FIFOs, and multiprotocol transceivers to provide four fully
independent synchronous/asynchronous serial channels. These features, along with a high performance PCI interface
engine, give the PC104P-SIO4BX unsurpassed performance in a serial interface card.
