Setting internal jumpers

The jumpers inside the interface(s) are set at the factory for optimal use by most systems. However, you can change a jumper setting to meet the needs of a particular system.

The user-configurable, internal jumpers control the following functions:

•horizontal and vertical sync polarity

•vertical sync pulse width.

Follow these steps to change the jumper settings. The RGB 134xi is shown for illustration, but the steps apply to all interfaces.

1.Remove power from the interface by disconnecting the AC power cord from the unit.

2.Open the cover of the interface (the top half of the enclosure), as shown below. Remove the screws from the enclosure, and lift the cover straight up.

Do not touch any switches or electronic components inside the interface. Doing so could damage the interface.

Slide cover back slightly, lift straight up.
