Common Connectors

The following tables describe connectors used with the same pin
assignments by MVME712M- as well as MVME761-compatible
versions of the base board.

LED Mezzanine Connector J1

A 14-pin connector (J1 on the base board) supplies the interface
between the base board and the LED mezzanine module. On the
base board, this connector is a 2x7 header. On the LED mezzanine,
it is a 2x7 surface-mount socket strip.
Removing the LED mezzanine makes the mezzanine connector
available for service as a remote status and control connector. In
this application, J1 can be connected to a user-supplied external
cable to carry the Reset and Abort signals and the LED lines to a
control panel located apart from the MVME2603/2604. Maximum
cable length is 15 feet. The pin assignments are as follows:

Debug Connector J2

A 190-pin connector (J2 on the MVME2603/2604 base board)
provides access to the processor bus (MPU bus) and some
bridge/memory controller signals. It can be used for debugging
purposes. The pin assignments are listed in the following table.
