Changing the input level/peaking
Users can set each input’s level/peaking value (from 000 through 255) from the
Picture Settings page. Level/peaking can be adjusted to compensate for longer
cable runs on the inputs. Change an input’s level/peaking setting in any of the
following three ways:
• Use the auto calibration function as follows:
1 . Disconnect the power and RJ-45 cables at the MTP transmitter connected
to input to be calibrated.
2 . Connect the two cables to the included MTP signal generator.
3 . If the input cable is longer than 300' (90 m), place the MTP signal
generator’s Pre-Peak switch on (up when the signal generator‘s RJ-45
connector is to the right [figure 6-11]). If the cable is shorter than 300'
(90 m), place the switch down.

Toggling output pre-peaking on and off
Users can toggle each output’s pre-peaking value on and off from the
Picture Settings page. Click in the desire output’s Pre-Peaking check
box 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 the
table on page 1-5 for recommended maximum transmission lengths.
