Setting Internal Jumpers - Extron electronics Universal Interfaces RGB 130xi User Manual

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.

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:

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