REMOTE INTERFACE

The programmable controller (UPC-Series Controller) is supplied with one of two remote
interfaces. These are the GPIB (General Purpose Interface Bus) or RS-232 Interface.
Connection information relative to these interfaces is described in detail in the UPC-Series
Operation manual.

AUX I/O INSTALLATION

The Auxiliary Input/Output signals may vary between the different controllers. However, the
method of connection remains the same.
The AUX I/O connector contains synchronizing outputs (digital) and modulation inputs
(analog). These are extremely useful in certain test applications. The use of any of these
signals is optional and connection to these points is required only when these features are
used.
The AUX I/O connector is located on the rear panel of the power source and is labeled as
such. This is a DB-25S connector. A DB-25P connector is required for connection to AUX
I/O connector.
All signals contained within the AUX I/O connector are low-level (less than ±15 VDC) and are
with respect to earth ground reference. Refer to the appropriate controller operation manual
for complete definition of the signals present on the AUX I/O connector.
