Setting DIP switches and jumpers

DIP switches and jumpers must be set and tested before the interface is secured into the wall box, wall or furniture.

DIP switches

DIP switch module SW1 contains two DIP switches (SW1-1 and SW1-2). The module is located on the circuit board on

 

SW1

the back of the interface, as shown on pages 2-6,

 

 

 

 

 

2-7, 2-9, 2-11 and 2-13. In these illustrations, the

Different video projectors may have slightly different sync requirements. Use the DIP switches on the interface to make the interface’s output compatible with the projector.

DIP switch 1 (SW1-1) controls serration pulse output.

ON = No serration pulses will be output in the composite sync signal.

OFF = Serration pulses will be output.

DIP switch 2 (SW1-2) controls sync processing.

ON = Digital Display Sync Processing (DDSP) will be used. This may be required in order to obtain a stable picture on some digital display devices.

When DDSP is on, horizontal shift (centering) is disabled.

OFF = DDSP will not be used.

Jumpers

Video signals passing through long cable runs (over 125 feet) or through poor quality cables can decrease in strength, creating signal loss. The longer the cable, the higher the video level and the greater the peaking that will be needed to compensate for the loss.

The gain/peaking adjustment jumpers are located on the circuit board on the back of the interface, as shown in the rear features sections of this manual. To configure the jumpers, use pliers to pull the jumper shunt off the pins, then place the jumper on the appropriate pins.

Make sure the interface is disconnected from the power source before configuring jumpers.

Changing jumper settings

2-14 RGB 400 Series Installation and Operation

Each red (J8), green (J9) and blue (J10) jumper can be set to one of three positions to provide unity gain (0.7 volts p-p),

0.8volts p-p, or 0.9 volts p-p output. Select the setting that yields the best image display. Use the diagram on the product label (shown below) as a guide to setting the output gain/peaking for each color.

0.7V — Use this for short cable runs (under 125 feet).

0.8V — Use this for long cable runs for all frequencies.

0.9V — Use this setting for long cable runs and high frequency video signals.

Attaching adapter plates (RGB 408)

The RGB 408 can have up to 4 optional adapter plates. The adapter plates allow for a variety of types of pass-through audio and/or video connectors to be added to the interface’s front panel faceplate.

Blank plates (two single-height and one double-height plate) are included with the RGB 408 to cover unused spaces. Other adapter plates must be ordered separately. They also must be attached to the faceplate and cabled before the interface is installed in the wall or furniture. The screws needed for installing the adapter plates are built into the plates, so no additional screws will be needed.

1.

Remove the blank plates from the interface by

 

 

unscrewing the nuts that fasten the plates to the

 

 

faceplate.

 

2.

Insert the adapter plate screws through the holes in

 

the faceplate. Attach the adapter plates to the

 

 

faceplate with the provided captive washers and

 

 

#4-40 nuts. See the illustration “Installing optional

 

adapter plates” on the next page.

 

3.

Attach the output cables to the connectors on the back

 

side of the adapter plates. Several adapter plates

 

 

require conductors to be soldered to the connectors.

 

Attach foil and braided shields to ground connections.
