Auto Equalization (Auto EQ)
The HDMI CAT5 Extender has advanced equalization circuitry to compensate
for the differences that are present in CAT-5 (CAT-5e or CAT-6) cable quality and
skew. Auto EQ is enabled by default. In some cases Auto EQ may not result in
an optimal video signal. If either of the two following conditions are experienced,
Auto EQ will have to be disabled and manual adjustment procedures will need to
be applied.
1. The CAT-5, CAT-5e or CAT-6 cable length exceeds 130 feet (40 meters).
This distance estimate is based on high quality CAT-6 cabling. The actual
distance at which Auto EQ will operate is based on the cabling used.
2. There is no video output from the HDMI CAT-5 IR Extender receiving unit
upon initialization of all connected devices.
Manual Equalization
Manual equalization uses two settings (Boost and Equalization) to produce
an optimal video signal. These two adjustment options will need to be jointly
adjusted as they are related to each other.
Setting Manual Equalization
Manual equalization is set by accessing a bank of 4 DIP switches on the
underside of the HDMI CAT-5 IR Extender receiving unit. The bank of 4 DIP
switches is located underneath a piece of metallic colored tape. Remove this
tape to expose the DIP switches. Only DIP switch 1 is used on this bank. DIP
switches 2 through 4 are not used. Auto EQ is on by default (DIP switch 1 is
OFF). To turn OFF Auto EQ and enter manual equalization mode, turn DIP switch
1 ON. Please see the illustration below.
