MANUAL EQUALIZATION PROCEDURE
The DVI CAT5 4X Extender and DVI CAT5 MSR receiver units both have sets of
dip switches located on the underside of their casings. There is a piece of silver
metallic tape that must be removed to expose these dip switches. The DVI CAT5
4X Extender unit carries 4 banks of 4 dip switches. Each DVI CAT5 MSR receiver
carries one bank of 4 dip switches. Dip switches 1 and 2 on both the sending and
receiving units are used in this procedure. Dip switches 3 and 4 are not used. By
default, dip switch 2 on each bank of the DVI CAT5 4X Extender should be in the
ON position, and all dip switches on each DVI CAT5 MSR receiving unit should
be in the OFF position (Auto EQ On). To turn off auto equalization, turn dip switch
1 on the receiving units to the ON position (Auto EQ off). With these settings,
please follow the steps below to equalize the picture.
Insert a small fl at head tool into the trim pot on the receiver unit.
1.
Turn the trim pot in a clockwise fashion until it comes to a stop. Do not force
2.
the trim pot beyond this point. Doing so may render the trim pot useless.
Slowly turn the trim pot counter-clockwise in millimeter increments until the
3.
image stabilizes and all video noise disappears.
Carefully remove the adjustment tool.
4.
NOTE:
If your cable run is beyond 130 feet, or the steps above do not produce
any video, it may be necessary to increase the boost from the sending unit. Use
the chart below to increase the senders to medium boost by changing the DVI
CAT5 4X Extender’s dip switches. Once a new boost setting is set, repeat steps
1 through 4 from above. If this still does not produce and image, increase the
boost to high and repeat the EQ process.
