VGA VIDEO SPLITTERS

6.1 Common Concerns

If the display colors on all the monitors seem to be “reversed,” this might be
caused by improperly setting the

MONITOR TYPE

DIP switch on the front

panel. Recheck the switch setting (see

Section 3.2

, step 7).

If one or two colors are missing on one of the VGA monitors, make sure

all connections to the VGA Video Splitter are secure. Make sure the monitor
connector’s jackscrews are tightened.

If problems persist, call for technical support.

6.2 Calling BLACK BOX

do not attempt to alter or repair the unit

. It contains no user-serviceable parts.

description, including:

appears to create the problem or make it worse.

6.3 Shipping and Packaging

If you need to transport or ship your VGA Video Splitter:

• Package it carefully. We recommend that you use the original container.

are returning the Splitter, make sure you include everything you received
with the unit. Before you ship, contact Black Box to get a Return Materials
