devices for pass-through input (network, composite video, S-video and/or other inputs) via front panel or front adapter plate connectors.

Determine what computer-video format the display device requires: separate horizontal and vertical sync (RGBHV), composite sync (RGBS), or sync on green (RGsB or SOG). No matter what format the computer outputs to the interface, the output from the interface to the display device can be RGBHV or RGBS. If the video format input to the interface is RGsB (SOG), RGsB can be output to the display device; otherwise only RGBHV and RGBS are available as output options.

Connect the display device to the interface using coaxial cables. Attach the cable’s BNC connectors to the appropriate rear panel BNC connectors on the interface based on the video format required by the display device.

Attaching power cables

Each RGB 400 Series interface requires an external voltage source of 12 to 24 volts AC or DC (250 mA maximum, 5 W). The interfaces are supplied with a power cord of twisted- pair wire soldered to the circuit board.

1.Splice these wires to the cord of a user-supplied power source. Polarity is not important, even if the power source supplies DC voltage. Extron offers an optional external power supply. See Appendix D for the part number.

2.Solder and insulate the connections.

Pre-installation testing/troubleshooting

Before installing the interface into the wall or furniture, test the system to make sure that the connections and interface settings are correct.

Turn on the input device(s) (computer, audio device) and output device(s) (projector and/or monitor, speakers). The image should now appear on the screen, and, for all models except the RGB 400, sound should be audible.

If the image does not appear or there is no sound

1.Ensure that all devices are plugged in.

2.Make sure that each device is receiving power. The interface’s Auto power indicator LED will light if the interface is receiving power and an active sync signal.
