VSC/3i Synchronous Serial Port Connectors
Devices connect to the VSC/3i ports (or channels) through 25–pin female DB25
connectors marked “CH A,” “CH B,” and “CH C.” The signals supported by each
connector on your VSC/3i air dam depend on the interface type you select when
configuring your VSC/3i. Figure C–5 shows the VSC/3i rear panel connector, and
Table C–3 lists the signals and pin numbers for each electrical interface supported
by VSC/3i connectors.
IMPORTANT: This section provides only the signals leaving the VSC/3i DB25
connector, not the cable connector signals.
