7. Operation
TP115-120 Transmitter
The TP115-120 requires no adjustments for operation. Once connected,
the TP115-120 will work trouble free without user intervention.
TP115-120 Receiver
The TP115-121 Receiver requires only video equalization for optimal
performance. Once adjusted for best image quality, the TP115-121 will
work trouble-free without user intervention.
Long cable lengths require video equalization. Set the video equalization
knob to minimum and adjust until the image quality is good. Note that
some displays take several seconds to respond to input signal changes. For
best results, adjust the video equalization knob in small increments and
wait 2-3 seconds for the display to respond
8. Troubleshooting Guide
We have carefully tested and have found no problems in the supplied TP115-120/121. However, we would like to offer suggestions for the following:
Switcher
Symptom
Resolution
LEDs Are OFF
1. Make sure the unit is plugged into a working AC outlet and the DC plug is inserted all the way into the switcher.
2. Use only the power adapter provided.
No Display
1. Check the source and make sure there is a signal present.
2. If a signal is present, make sure the Power/Signal Present on the TP115-120 Transmitter is ON and GREEN and
that the Power/Signal Present LED on the TP115-121 Receiver is ON and GREEN.
Note: If the source is Component Video (YPbPr) the LED is RED on the TP115-121 Receiver.
3. Make sure the display has power and is turned on.
4. The cable length may require video equalization at the receiver. Set the video equalization knob to minimum on
the receiver and adjust until the image quality is good. Note that some displays take several seconds to respond to
input signal changes. For best results, adjust the video equalization knob in small increments and wait 2-3 seconds
for the display to respond.
Poor Output Image
1. The cable length may require video equalization at the receiver. Set the video equalization knob to minimum on
the receiver and adjust until the image quality is good. Note that some displays take several seconds to respond to
input signal changes. For best results, adjust the video equalization knob in small increments and wait 2-3 seconds
for the display to respond.
2. The source resolution may not be compatible with the projector or other display device. Try other resolutions from
the source.
3. The source and display may not be compatible. Connect the source directly to the input of the projector or other
display device. If the image is poor the devices may be incompatible.
