7. Slide the unit up and down or back and forth in the mounting brackets until
the front panel of the unit is at the desired height. Tighten the screws that

Grounding the transmitter
RGB and computer video transmitters may need to be grounded to ensure that the
video and audio signals are not degraded. The TP T 15HD A and TP T 15HD AV
may require grounding if all of the following conditions exist:
• The signal source is a laptop computer.
• No local monitor is connected.
• A local power supply is not being used.
Grounding may also be required if there is no common ground in the power
distribution system.
Indications that grounding may be required include:
• The receiver’s Power LED is lit amber when a connection is made to the
transmitter.
• The receiver is in auto mode and its Manual/Auto LED flashes.
• The receiver is in manual mode and an image appears only when the
Peaking adjustment is at the minimum level. Additionally, the image
may be overpeaked with horizontal streaking to the right of the displayed
information.
• No audio, or distorted and noisy audio, is heard.
Ground the transmitter using any of the following methods:
• Connect a local 15 V power supply to the transmitter.
• Use STP rather than UTP cable and connectors.
• Use a 3.5 mm captive screw connector to
connect a ground wire between the power
return pin and a grounding point near the
transmitter, such as a grounded power outlet
or an equipment rack. (See the illustration at
right.) Use this method if you are not using
local power.
