Installation and Operation, cont’d

3.Check the cabling and the audio connector wiring, and make adjustments as needed.

4.Verify that the High Z/75 Ohm video input termination toggle switch on the front panel has been set correctly.

5.For digital display devices (including LCD, DLP and plasma devices), try turning DDSP on or off using the rear panel SW1-2 DIP switch.

6.Call Extron’s customer support hotline if needed.

If the image does not display correctly

1.If the output image looks too green, the computer may be sending video with sync on green (SOG), and the display device may not be configured to handle SOG signals. The RGB 400 Series interfaces do not strip sync from the video input signals.

2.If the picture bends or flags at the top of the screen, set the serration pulse DIP switch (SW1-1) to Off.

3.For a display device that experiences intermittent glitches, try turning DDSP on or off using the rear panel SW1-2 DIP switch.

4.If the picture “hangs off” the edges of the screen, adjust the H. Shift horizontal centering control.

5.If the edges of the image seem to exceed their boundaries or if thin lines and sharp edges look thick and fuzzy, try changing the gain/peaking jumper (J10, J9, J8) settings. If the image is too bright, decrease the gain/peaking level.

6.If the image appears and is stable, but it has ghosting or blooming, check the High Z/75 Ohm video input termination. If changing the termination doesn’t solve the problem, try using a different input cable.

7.If the image still does not display correctly, call Extron’s customer support hotline.

If no image or sound results from pass-through connections

1.Make sure each input device is connected to the correct pass-through connector, which in turn is connected to the appropriate output device.

2.Ensure that each connector is properly wired and grounded, and that each device is powered on.

3.If there still is no image or sound, try cabling the input device directly to the output device. If that resolves

the situation, either the pass-through connector or any cable that was part of the installation but not used for this test may be the source of the problem. If this test does not produce an image or sound, the problem may lie with an input device or an output device.

Mounting the interface to the wall box

Once the system has been cabled and tested, the interface can be installed in the wall or furniture.

1.Remove power from the interface and input and output devices by disconnecting the power cords from the power supply.

2.Detach the input cables from the front panel.

3.For the RGB 408 only, install the EMI strips.

To maintain proper grounding connections between the interface faceplate and the wall box, adequate contact between the faceplate and wall box must be ensured. Installing the supplied EMI (electromagnetic interference) strips will ensure the proper contact and maintain the ground. To install the strips, do the following:

a.Peel off the protective, papery coating from the back of an EMI strip.

b.Apply the EMI strip to the center of the upper lip of the 4-gang wall box, pressing firmly to ensure contact. See the illustration below.

c.Repeat steps 1 and 2 to install the other EMI con- ductive strip onto the lower lip of the wall box.
