Wiring the audio output connector

9Autoswitching/Contact closure connector — Connect a contact closure control device to the left three pins of this 3.5 mm, 5-pole captive screw connector.

•Pin 1 selects input 1 when connected to ground (pin 3).

•Pin 2 selects input 2 when connected to ground (pin 3).

•Pin 3 connects to the ground wire (equipment ground).

CONTACT AUTO-SW

Jumper pins 4 & 5 for autoswitching.

Contact Closure Control

•Pins 4 and 5 if jumpered/shorted together will turn the autoswitching mode on. When the autoswitching mode is on, the switcher automatically switches to the input that has an active sync signal.

If both inputs have an active sync signal present, the highest input, input 2, will be used, and the input 2 indicator LED will light. If no active sync signal is present, neither input indicator LED will light.

Autoswitching overrides manual input selection. If autoswitching is on, contact closure and front panel input selection will be disabled.

•If pins 4 and 5 are not connected, manual switching is enabled. Selections can be made via the front panel selection switches and the contact closure device.

If no active sync signal is present, the input 2 indicator LED will still light.

Attach cables to the switcher as detailed in the steps below. The diagram in this section shows how the system looks when cabling is finished.

1.Attach the computers’ video output cables to the switcher via the 15-pin HD female input connectors. If the computers will provide the audio input, VGA with audio combination cables, such as the Extron VGA HRA series (#29-491-01 to #29-491-05), can be used.

2.Connect the cables from the stereo audio sources (computers or other devices such as CD players or tape decks) to the audio input jacks. The audio plug should be wired as shown below.

3.Connect VGA cables from the switcher’s 15-pin HD female output connectors to the display devices (projectors, monitors).

4.Connect the speakers’ or other audio output device’s cable to the switcher’s audio output captive screw connector.

5.Attach the contact closure device to the left three pins of the 5-pole captive screw Contact/Auto-sw connector.

6.Connect power cords and turn on the devices in the following order: display and audio output devices (projectors, monitors, speakers), contact closure controller, SW2 VGA DA2 A /AF switcher, and input devices (computers, audio sources).
