6. Troubleshooting

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 3.1, 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, contact Black Box Technical Support.

6.2 Contacting Black Box

If you determine that your VGA Video Splitter is malfunctioning, do not attempt
to alter or repair the unit. It contains no user-serviceable parts.
Contact Black Box Technical Support at 724-746-5500 or info@blackbox.com. The
problem may be solvable over the phone.
Before you do, make a record of the history of the problem. We will be able to
provide more efficient and accurate assistance if you have a complete description,
including:
• the nature and duration of the problem.
• when the problem occurs.
• the components involved in the problem.
• any particular application that, when used, 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.
• If you are shipping the splitter for repair, include its power supply. If you 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 Authorization
(RMA) number.
