Power LED
Amber — indicates that power is applied, but that the
transmitter is not connected to a receiver.
On the TP R BNC AV only, and only if the composite
video TP link is used and the RGB link is not used, this
LED will only light amber.
This LED will only light amber if the transmitter is a
VTT001.
Green — indicates that a transmitter is connected and any
of the following grounding conditions exist:
• The transmitter is powered by a local power supply
and the receiver’s output is connected to a device
that provides a reference ground.
• The transmitter is powered by the receiver, is locally
grounded, and the receiver’s output is connected to
a device that provides a reference ground.
• The transmitter is receiving power from the
receiver, a local monitor is connected to the
transmitter, and the receiver’s output is connected
to a device that provides a reference ground.
• The receiver is connected through a TP switcher to
a device that provides a reference ground.
2
Manual/Auto switch (TP R BNC A and TP R BNC AV) — With
this switch in the Auto position, the receiver automatically
adjusts the level and peaking to compensate for long cable runs.
In the Manual position, you can manually compensate for long
cable runs using the level and peaking controls.
If the transmitter is a VTT001, this switch should
always be set to Manual.
3
Auto LED (TP R BNC A and TP R BNC AV) — Indicates that
the Manual/Auto switch is in the Auto position.
4
Level control — Adjusts the image brightness.
.
Peaking control — Adjusts the image sharpness.
For details on the SOG and C SYNC switches, see
Computer video earlier in this chapter.
Troubleshooting
If the image does not appear
1. Ensure that all devices are receiving power. The
transmitter’s and receiver’s front panel Power LEDs
indicate that they are receiving power.
2. Ensure that the transmitter is receiving a video input.
3. Ensure that the TP cable(s) are properly terminated in
accordance with TIA/EIA T 568A standards and that the
RJ-45 connections are securely made. If the Power LEDs
on the transmitter and the receiver are lit green, a
transmitter is properly connected to a receiver.
4. For computer/RGB video, ensure that the receiver’s SOG
and C Sync switches are in the correct positions for the
video output.
5. For computer video, ensure that the transmitter’s ID bit
switches are on.
6. For computer video on an LCD projector, ensure that the
transmitter’s DDSP switch is on.
The TP T 15HD 45 and TP T A 45 do not have the
DDSP feature.
7. The transmission distance may be too far for remote
power. Try connecting the local 15V power supply to the
transmitter.
