Programmable Inputs

Programmable inputs are provided to enable external
control over a variety of parameters. Each input can
respond to a contact closure, a DC voltage source,
or the variable voltage output from a potentiometer.
The following illustrates common connections to the
programmable input pins.

Installation and Quick Start Guide

Programmable Outputs

Programmable outputs are used for several purposes:
• indicate the current state of a programmable input
• monitor activity on audio input channels
• monitor active preset changes
Each programmable output is the electrical equivalent
of a contact closure to ground. When a programmable
output is "active" it conducts current to ground. When
the programmable output is "inactive," no current flows
to ground. The maximum usable voltage for the pro-
grammable outputs is 40 V and they will safely conduct
up to 100 mA DC continuous.
Both LEDs and 5V relay coils can be powered by the
+5 V DC pins on the programmable input connector, as
long as the maximum combined current for all LEDS
and relay coils does not exceed 100 mA.

Note: The diagram above shows an external DC source
