● PCI Bus

● I/O Connection: 9-pin male D-sub connectors.

● Serial Ports: Two shielded male D-sub 9-pin IBM AT style connectors compatible with RS-232(PCI-COM2S only), RS-422 and RS-485 specifications.

● Character length: 5, 6, 7, or 8 bits.

● Parity: Even, odd or none.

● Stop Interval: 1, 1.5, or 2 bits.

● Serial Data Rates: Up to 115,200 baud, Asynchronous, Asynchronous. A faster range of rates, up to 460,800 baud, is achieved by jumper selection on the card. Type 16550 buffered UART.

Caution: The OUT2 bit of the UART must be set low for proper interrupt driven communication. This bit enables or disables the interrupts and the card will not communicate if the bit is pulled high.
