Figure 5 — Wiring for audio output

Power connector

Attach the 3-pole, 3.5 mm captive screw power connector to a 12 to 24VDC or 12 to 24VAC, .5A (minimum), external power supply, such as Extron’s #70-055-01.

The center pole contains no conductor. Connect conductors to the outer two poles only.

Polarity is not important: the positive or negative wire can be connected to either of the outer poles.

Signal cables

Attach the BNC connectors to the video display device.

•For RGsB, attach the red, green/sync, and blue cables.

•For RGBS, attach the red, green, blue, and black (sync) cables.

•For RGBHV, attach the red, green, blue, black (horizontal sync), and yellow (vertical sync) cables.

Connecting input cables

Connect the input cables temporarily for testing. (Figure 6, on the next page, shows a typical application.) Then, disconnect them so any switch or jumper adjustments can be made. The interface can then be installed in the Ackermann floor tank.

Input cables can be reconnected after the interface is installed.

Use only Extron cables. Extron does not guarantee the performance of the interface if a low quality cable is used for the input.

Connect the computer video and audio input cables and (for RGB 560 AKM) the local monitor output cable.

Pre-installation testing/troubleshooting

Before completing the installation, test the system to make sure that the connections and interface settings are correct.

1.Turn on the input device(s) (computer) and output device(s) (projector and/or monitor). The image should now appear on the screen.

2.If the image is not displayed at all, double-check cable connections, and ensure that all devices have power and are turned on. For the RGB 500 AKM interface, try changing the video termination toggle switch setting. For the RGB 560 AKM interface, if no local monitor is present, change the ID bit termination via the front panel DIP switches, then reboot the computer.
