Connection
A 25-pin DSub connector (DB-25) is used for accessing the GPIO functions. Although you
can terminate GPIO functions directly to the DB-25 connector, we recommend that you use
the optional breakout accessory (GPIO-25: Peavey Part# 00510490).
The GPIO-25 is a convenient way to access each pin and facilitates easy rack wiring and
troubleshooting. The GPIO-25 is a DIN rail package and includes removable Euro
connectors for terminating the pins. A single DB-25 male/female cable connects the GPIO-
25 to the NION or CAB 4n.
