Crossover Cable Wiring Diagrams

The following wiring diagrams illustrate the types of cables that should be used to make the connection between specific devices and the ISI4608-PCI card. The ports on each card are wired according to the RS232 standard for data terminal equipment (DTE) that implements a male connector.

If you have an ISI4608-PCI, the 8-port fan-outcable has eight 25-pin male connectors (shown in Figure A-1).
