8. Troubleshooting Guide
We have carefully tested and have found no problems in the supplied TP115-201/202. However, we would like to offer suggestions for the following:
Symptom Resolution
ALTINEX Logo is NOT
Illuminated Yellow
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.
EDID LED is
Always RED
There is no EDID available on the local monitor or the local monitor is not connected.
1. Make sure the local monitor is connected to the TP115-201 using the VGA cable provided and restart the video
source to ensure the source recognizes the EDID memory from the monitor.
2. If the video is Component, the LED is RED indicating the internal EDID is selected (not applicable to YPbPr).
Video Type LED is OFF
The TP115
-
201 recognizes VGA and Component (YPbPr) video signals.
If the signal is not VGA or Component then the LED is off.
1. Make sure the video source is on and active.
2. Check the image at the local monitor. Make sure the source is not in power save or screensaver mode.
No Display on Projector
1. Check the source and make sure there is a signal present.
2. Make sure the projector has power and is turned on. If the projector power is controlled by the transmitter through
IR or RS-232 control, make sure the cables are connected and the correct codes have been selected.
Control Signal Improperly
Routed
1. Make sure the correct cable is being used to control the projector, IR or RS-232.
2. If using IR, use an ALTINEX IR Emitter plugged into the IR OUT connector of the receiver and an ALTINEX IR
Receiver at the transmitter.
Poor Output Image
1. The source resolution may not be compatible with the projector/display device. Try other resolutions.
2. 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.
3. Long transmissions require varying degrees of video equalization at the receiver. Se
t the potentiometer to minimum
(fully CCW) and then slowly increment toward maximum. Pause in between each increment in order to allow the
display to process the change to the incoming video signal.
No Sound
Analog audio is only available with VGA (comput
er) video signals. If the video is YPbPr and the audio i
nput is
analog,
there will be no audio on the output of the receiver or the audio may have intermittent distortions and interruptions.
Audio for YPbPr must be optical or digital (coax) audio.
1. Make sure the speakers are connected to the speaker output on the switcher.
2. Make sure audio is playing and that any mute settings are disabled.
Audio or Video Distortion
During RS-232 or IR
Transmissions
In most cases there is no noticeable distortion to the twisted pair signal during
typical
IR or RS
-
232 transmission.
However, if the transmission is long enough or is sent repeatedly there may be some distortion to the audio signal; this
is normal. Additionally, IR and RS-232 signals cannot both be transmitted at the same time.
Note that some devices (for example digital to analog audio converters) take longer to respond to disruptions in audio
signal than others. In some cases, the audio may be "muted" until the distortions due to data transmission are done.
1. Make sure the IR or RS-232 cables are properly grounded.
2. Keep the cable lengths from the output of the units as short as possible.
3. Make sure to use the proper video/audio sources or the distortions will be "louder" than normal.
Computer (RGBHV) with Analog Audio OR Component (YPbPr) with Digital/Optical Audio
Audio or Video Distortion
With No RS-232 or IR
Transmissions
There should be no
distortion to the twisted pair
audio
sig
nal. However, if the
wrong audio type is used there may
appear to be intermittent distortions when there is no IR or RS-232 data being transmitted.
1. Make sure only digital or optical audio is used with component (YPbPr) video. Transmitting analog audio with
component video will result in intermittent interruptions in audio.
2. Make sure only analog audio is used with COMPUTER (RGBHV) video. Transmitting digital audio with
COMPUTER video will result in intermittent interruptions in audio.
