Changing the input level and peaking
Users can set the level and peaking value (from 000 through 255) for each input from the
Picture Settings page. Level and peaking can be adjusted to compensate for longer cable
runs on the inputs. Change the level and peaking setting for an input in any of the following
three ways:
z z Use the auto calibration function as follows:
1. Disconnect the power and RJ-45 cables at the MTP transmitter that is connected to
the input to be calibrated.
2. Connect the two cables to the included MTP signal generator.
3. If the input cable is longer than 300 feet (91.4 m), place the Pre-Peak switch on the
MTP signal generator to on (up when the RJ-45 connector on the signal generator
is to the right [see figure 69]). If the cable is shorter than 200 feet (60 m), place the
switch down.

NOTE: The MTP signal generator does not work on cable lengths over 400 feet
(120 m). Set the level and peaking to its maximum value of 255.
4. Click the Auto button.
z z Click the Level/Peaking up button or down button for the
desired input.
z z Directly enter a value into the Level/Peaking field.
NOTE: Watch a display as you make adjustments to set the sharpest, brightest
image.
Toggling output pre-peaking on and off
Users can toggle the pre-peaking value for each output on and off from the Picture Settings
page. Click in the
Pre-Peaking check box for the desire output to toggle the pre-peaking
feature on and off for that output. Pre-peak alters the TP signal output to correct for long
cable runs (see
table 1 on page 5 for recommended maximum transmission lengths).
Changing the skew
Users can individually set the red, green, and blue skew setting for each input and output
from the
Picture Settings page. The skew settings correct skew delay (misconvergence)
problems commonly encountered when using Category (CAT) 5, 5e, or 6 twisted pair (TP)
cables for RGB or component video transmission.
