digital I/O card / SCSI / RS-232 / CompactPCI
Number of inputs/outputs:
The 16-port RS232 unit has 16 16550-based UARTs and can run from 300 baud to 115 Kbaud.
This uses so-called interrupt requests from one of four INTx units on a PCIbus. The I/O is accessible from a 68-pin SCSI connector on its front panel. This also has a rear I/O to wire all ports to a P4 connector.
