Interfacing

Some general interfacing guidelines are presented below. Do not hesitate to contact the

factory if you need more assistance.

Installation

The PMC is mounted to the cPCIRepeat32 prior to installation within the chassis. For

best results: with the cPCI bracket installed, install the PMC at an angle so that the

PMC front panel bezel penetrates the cPCI bracket then rotate down to mate with the

PMC [PnX] connectors.

There are four mounting locations per PMC. Two into the PMC mounting bezel, and

two for the standoffs near the PMC bus connectors.

Start-up

A third party PCI device cataloging tool will be helpful to check that the VendorID and

CardID are "seen" by the OS.

Watch the system grounds. All electrically connected equipment should have a fail-

safe common ground that is large enough to handle all current loads without affecting

noise immunity. Power supplies and power consuming loads should all have their own

ground wires back to a common point.

Power all system power supplies from one switch. Connecting external voltage to

the cPCIRepeat32 when it is not powered can damage it, as well as the rest of the host

system. This problem may be avoided by turning all power supplies on and off at the

same time. This applies more to the PMC installed into the cPCIRepeat32 than the

cPCIRepeat32 itself, and it is smart system design when it can be achieved.
