Baud Rate Ranges

The card has capability for two baud rate ranges and you can select which you wish to use on a port-by-port basis. One range is for up to 115,200 baud applications and the other is up to 460,800 baud applications.

Specifications

Communications Interface

•	I/O Connection:	9-pin D-sub connectors
•	Serial Ports:	Four shielded male D-sub 9-pin IBM AT style connectors
		compatible with RS422 specifications. (Note: On model an
		external "spider" or breakout cable terminates with four female
		D-sub 9-pin connectors.)
•	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, A faster range of rates up
		to 460,800, is achieved by jumper selection on the card. Type
		16550 buffered UART.
