The problem is that when units are connected to different electrical outlets, there may be several volts of difference in ground potential. If pin 1 of each device is interconnected with the others via cable, several amperes of current could result. This condition may not only be dangerous for the small wires in a typical cable, but may also produce electrical noise that causes errors in data transmission. That is why Figure E-1 shows no connection for pin 1. Normally, pin 7 should only be connected to the CHASSIS GROUND at one point; if several terminals are used with one computer, the logical place for that point is at the computer. The terminals should not have a connection between the logic ground return and the chassis.
The MVME712M is an I/O transition module
for Motorola’s MPU VMEmodule, VME Processor Module, Embedded Controller, and Single Board Computer (SBC) families of processor modules, referred to in this manual as MVMExxxx. The MVME712M is used as an interface between the processor module and its peripheral devices. The purpose of this module is to provide rear panel industry-standard connectors that simplify external customer cable requirements. The P2 adapter board and cables are supplied for interconnection between the MVME712M and the MVMExxxx. The P2 adapter assembly routes the I/O signals and grounds from the P2 connector on the chassis backplane, at the VMEmodule MPU connection, to the MVME712M.
