Remote Status and Control

The remote status and control connector, J4, is a keyed double-row 20-pin
connector located behind the front panel of the MVME1600-011. It
connects to a user-supplied external cable and carries the signals for
remote reset, abort, the LEDs, and three general-purpose I/O signals. This
allows a system designer to construct a RESET/LED panel that can be
located remotely from the MVME1600-011. This feature is similar to the
remote connector provided on the MVME167 and MVME187 Single
Board Computers; maximum cable length is 15 feet.
The general-purpose I/O signals include two TTL-level I/O pins and one
general-purpose interrupt pin which can also function as a trigger input.
The interrupt pin is level programmable.
Table 1-3 lists the pin numbers, signal mnemonics, and signal descriptions
for J4.
