Setting Internal Jumpers

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

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

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

• horizontal and vertical sync polarity, and
• vertical sync pulse width.

Follow these steps to change the jumper settings.

1

. Remove power from the interface (if it is connected) 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.

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