MPI-16 & MPI-16H POCKET INDEXERS
1-6 General Description
1.5 Accessories
1.5.1 Remote
Panel
The Remote Panel is a required system component if you have chosen to operate the
MPI-16 without external control. The Remote Panel is a 3.5” high, quarter-size rack-
mountable interface that provides a Pocket Select Switch, Speed Select Switch, and an
Abort/Reset button. You may also toggle between Automatic and Manual operation if
you are using the Remote Panel in conjunction with external control. If your Pocket
Indexer kit included the Remote Panel, a 25-pin (straight-through) cable is also provided
for connectivity.
1.5.2 External Interface Cable
A standard 25-pin cable is supplied with all MPI-16 units to allow you to interface the
Pocket Indexer with any control device you wish. The most common options will be to
control the MPI-16 from a Deposition Controller or from a Programmable Logic
Controller (PLC) in your system. To provide maximum flexibility, the wires at the
opposite end of the cable have been left unconnected (loose). Refer to Table 3-2 for the
signal definitions of each pin. Since the colors of each wire may vary, a separate page
will be included with your interface cable specifying the color code.
If you do not plan on using the optional Remote Panel, you may connect the External
Interface Cable directly to the MPI-16. If you will be using the Remote Panel (via the
provided connector), you must connect the External Interface Cable to the auxiliary
connector on the Remote Panel itself. It will act the same exact way as if your control
device were plugged directly into the MPI-16.
1.5.3 Mounting Bracket
The MPI-16 includes a mounting bracket to allow for easy installation in your system.
The bracket mounts to a 1” rotary feed-through, and can accommodate a base plate
thickness of 1/2” to 1-1/8”. Please see Section 3.5 (Installation in Your System) for
further details.
1.5.4 Power Supply
A 48-volt (1.1 amp) power supply is included to provide reliable power for your MPI-16.
This powers the stepper motor as well as all of the low-voltage logic circuitry inside the
Pocket Indexer. It is recommended that you only use the provided power supply to
ensure reliability and integrity of the indexer operation.
