2Audio output and communications/power connector — Wire this 3.5 mm 10-pole captive screw connector as shown in “Connecting the buffer to the RGB 320 with installation cable” in this chapter (pages 2-11 to 2-14).

The left half of this connector is for audio output to the RGB 320. The right half of this connector serves as a port for power and buffer-RGB 320 communications.

3Level/peaking jumpers — Changes to video peaking may be needed for high resolution signals or to compensate for signal loss from long cable runs. The buffers have separate jumpers for red, green, and blue video signals. See the diagram shown here or on the product label, and, for the RGB 340, also see “Opening the RGB 340 enclosure for jumper adjustment” below.

Changes to internal jumper settings must be performed by authorized service personnel only.

•0.7V – This is the factory default setting. This is a general purpose level which is best for use with short cables.

•0.8V – Use this setting for long cables.

•0.9V – Use this setting for longer cables and/or very high resolution signals.

To configure the jumpers, use pliers to pull the jumper shunt off the pins, then place the jumper on

Opening the RGB 340 enclosure for jumper adjustment

The RGB 340’s level/peaking jumpers are located on the circuit board inside its enclosure. To open the enclosure and adjust the jumpers, do the following and refer to the illustration on the next page:

1Video output BNC connectors — Connect coaxial cables to these connectors for RGBHV, RGBS, RGsB, or RsGsBs analog video output. For composite sync (RGBS) signals, connect the sync cable to the BNC connector labeled V or VSYNC.

1.Remove power from the RGB 340.

2.Remove the five screws that attach the upper part of the enclosure to the lower part.

3.Remove the two hex bolts that fasten the front panel to the 9-pin D analog video input connector.
