Step 1 — powering down and mounting, Step 2 — connecting the input and output devices, Step 3 — connecting power

background image

This sheet provides quick start instructions for an
experienced installer to set up and operate the
SEQ 100 15HD Skew Equalizer.

Step 1 — Powering down and mounting

Power off all devices and disconnect them from the power source, then mount/locate the
SEQ 100 as desired.

Step 2 — Connecting the input and output devices

Connect an RGB source to the 15-pin HD input connector,
and connect an RGB display to the 15-pin HD output connector.

See the example application illustration below.

Step 3 — Connecting power

Plug the 12 VDC power supply into the 2-pole captive screw connector.

Step 4 — Adjusting for skew equalization

The skew equalizer provides 3 separate time delay circuits on the red,

green, and blue video lines. Each time delay circuit can be adjusted
using the three rotary switches, from 0 to 39 nanoseconds, to properly
align the red, green, and blue signals on the displayed image. To adjust the skew:

a.

Rotate all 3 rotary switches to the zero ( ) position.

b.

Use UTP cable test equipment or examine the displayed video image with a critical eye

to determine which video signal (red, green, or blue) is most shifted to the left.

N

A crosshatch test pattern is ideal dor determining pair skew.

d.

Adjust the left-shifted video signal’s rotary switch one step at a time while monitoring

the display. Step the switch until the video signal is properly converged.

N

The SEQ 100 cannot shift the rightmost video image to the left.

e

. If either of the other signals is misconverged, repeat steps a and b. See the table below

for switch positions.
