GPI, Ethernet & Power Connection
This section describes the remainder of the rear panel connections on AirCleaner,
including the GPI and Ethernet connectors, and the AC power inputs.
Figure 2-8. Rear Panel GPI, Ethernet and AC Power connections.
GPI Connector
The General Purpose Interface (GPI) connector features four GPI input triggers (no
output triggers are provided). The GPI port is used with the optional AirCleaner
control panel, which provides a method to trigger screening operations for either
audio, video or both. One may also construct their own triggering mechanism in place
of the optional AirCleaner control panel. For example, two hand-held trigger buttons
could be constructed and wired to the GPI port to trigger the screening operations.
The normal state of each GPI input is the “open” state; to activate any of the GPI
inputs, a “dry” contact closure is required.
Figure 2-9. GPI Connector Pinout
Table 2-1 on page 14 provides the pin-outs for the GPI connector. Using this wiring
chart, a customized cable can be wired for a custom control panel for AirCleaner.
Each GPI input trigger should be provided by a momentary, normally open switch
that connects between the given input pin and the ground pin (Pin 9). For example,
the
Screener 1: VIDEO Panic Trigger
switch is connected between pin 1 and pin 9 on
the GPI connector.
