AUX I/O INSTALLATION

On the rear panel J5, the AUX I/O (Auxiliary Input/Output) connector, contains synchronizing
outputs (digital), external oscillator inputs (analog), and amplitude modulation inputs (AM, 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.
All signals contained within the AUX I/O connector are low-level (less than ±15 VDC) and are
referenced to chassis (earth) ground reference. Refer to the UPC controller operation manual for
complete definition of the signals present on the AUX I/O connector.
The AUX I/O connector is a DB-25S connector. A DB-25P connector is required for connection to
AUX I/O connector.
