5.2.2.2 Rear I/O Interface
The optoisolated rear I/O module CP-RIO-345-OPT is provided with a PCI rear I/O inter-
face connector RJ2. All signals from the TTL serial I/O interface are routed to this con-
nector. The active high/low status of the signals depends on the protocol used.
N/C = not connected.
