Configuration

Configuring the Lift and Gain Settings and PWM

Task/Action (with Default)

Turning the Video Gain/PWM ON or OFF

1. Select 7 Enhanced Features
2. Select ON to adjust the lift and gain levels of the video when
running the video on unshielded twisted pair (UTP) wiring and
based on cabling distances or OFF (default).

Adjusting the Lift and Gain PWM (Pulse Width Modulation) Levels

1. Turn the Video Gain ON.
2. Select 7 Enhanced Features
• 2 Lift PWM
• 3 Gain PWM
3. Enter the required setting between 0–100. See the table below
for recommended lift and gain settings based on cable length.

Cable Length
1200+ ft (365+ m)
900 ft (275 m)
600 ft (183 m)
300 ft (91 m)

Adjusting the Char White PWM (Pulse Width Modulation) Level

1. Turn the Video Gain ON.
2. Select 7 Enhanced Features
3. Enter a value between 0–100, where:
• 0 is dark
• 100 is bright
• 50 is the default

Notes

The lift setting boosts the high frequency
in the video to compensate for high
frequency losses caused by capacitive
roll-off of the cable distance. The longer
the distance of UTP wiring, the higher the
setting.
Caution This setting is used to brighten
or darken the characters in the OSD.
Selecting values greater than 50 can
cause the phosphor in some monitors to
burn the character images into the
monitor.
