The PCI-SIO8BXS board is an eight channel serial interface card which provides high speed, full-duplex, multi-protocol serial capability. The SIO8BX combines four multi-protocol Dual Universal Serial Controllers (USC®), 16 external FIFOs, and multi-protocol transceivers to provide eight fully independent asynchronous or synchronous serial channels. Multiprotocol Transceivers support RS422 (V.11)/RS485, RS423 (V.10), RS232 (V.28), RS530, as well as other Mixed Protocol modes. These features, along with a high performance PCI interface engine, give the PCI-SIO8BX unsurpassed performance in a serial interface card. The PCI-SIO8BXS is based on the four channel SIO4BX product line from General Standards Corporation. In order to maintain software compatibility, the PCI-SIO8BXS is implemented as two independent four channel SIO4BX cards.
