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.

3. Note the positions of jumpers J20 and J40 before

changing jumper settings. The illustration of the

following circuit board shows the locations of the J20

and J40 jumpers. There are two possible setting

combinations for 3-pin jumpers:
