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-out cable has eight 25-pin
male connectors (shown in Figure A-1).
