Installation
Note: Signals at the User port can be sensitive to environmental noise. We
recommend that you take standard preventative measures against electro-
magnetic interference (EMI), including using shielded cabling on the User port
Note: Grounding the User port at the power supply reduces noise interference. To
avoid ground loop problems, you should typically ground only one end.
Refer to the pin descriptions on the following pages when connecting your remote
controller to the User port. Use shielded cabling to avoid EMI problems.
If you have a Pinnacle Active Remote Panel and you want to operate the Pinnacle
supply from the User port, you must set the control mode for USER on the control
panel.
Signals
The User port is primarily an “analog” interface. Signal descriptions appear in the
following table. Note that a “.A” suffix appended to a pin name indicates an analog
signal; a “.D” suffix appended to a pin name indicates a digital signal. An overline on
a signal name (for example, OUTPUT ENABLE.D
) indicates that the signal is true
when low.

Disconnect all sources of input power before working on this unit or
anything connected to it.
Power down the Pinnacle unit and take proper ESD precautions before
removing the unit's top cover to position jumpers. Failing to power down
the unit in this case could result in death or severe personal injury.
Failing to take proper ESD precautions in this case could result in
