Relay Input Connections -- J2
The relay input connections appear on a 50-pin female micro-ribbon telco style
connector, J2. The relay input connector is laid out to match the MCN IOB
module pin-for-pin. J2 can be connected to the IOB module directly through a 25-
pair straight-through male to male cable.
Since the MCN CIB module was originally set up to match the Digitac P805
pinout, the signals are a bit scrambled. For convenience, the pinouts are as shown
in two tables, the first sorted by relay and function, and the second sorted by pin
number. The corresponding signal names for the CIB and IOB modules are also
shown.
