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.
