MPI-16 & MPI-16H POCKET INDEXERS
Setup and Installation 3-11
3.6 System Connections
On the rear side of the MPI-16, there are two connectors providing all the necessary
signals to complete interfacing with other system components (see Figure 3-10). The
DSUB-25 Male, I/O Port connector provides inputs and outputs, and the 2-Pin terminal
block, Interlock Output connector, provides the safety interlock signal.
3.6.1 I/O Port Connector
Use the provided DSUB-25 Female I/O cable to connect the MPI-16 to your film
deposition controller or PLC (programmable logic controller). Connect the female end of
the cable to the MPI-16 I/O Port, and wire the open-end of the cable to your controller
accordingly. Table 3-2 shows the signal pin assignments for the MPI-16 I/O Port
connector. Refer to your controller manual for their I/Os.

Outputs are pulled-up to 5 volts through a 4.7 K ohms resistors (50 mA max). Low true is with respect to
the output return (Pin 10). All outputs are optically isolated transistors.
