Q: No video image is received at the receiver module.
A: Check that the both the red power indicators are lit on both the transmitter and receiver modules - if they are not, then there is a power problem. Both modules require power from their supplied power adapters. Check that the green video input indicators are lit on both the transmitter and receiver modules - if one or both are not lit, then a valid video input signal is not present at the input to that module. Check the link cable(s) that connect the transmitter and receiver module(s) for soundness and correct wiring as per the diagram in the manual. If possible, try testing an alternative twisted pair link connection between the modules. If the sharpness control is set too high, the monitor may not be able to display a picture. Try reducing the sharpness setting. If not already fitted, connect a monitor to the OUT port of the transmitter module and check for a correct video image output.
Q:
The colours have all separated.
A: You may need to adjust the skew, please see the " Skew compensation adjustments (AV101 & AV200 only)" section of the manual for details.
Q: How do I cascade the units?
A: ALAV100 units may be cascaded at the transmitter or receiver, ALAV 200 units can be cascaded at the transmitter. Please see the "Making cascade connections" section of the manual for more details.
Q: What is the maximum resolution suported in a cascade enviroment?
A: The maximum resolution supported depends on the distance between the transmitter and the receiver and the number of cascade links in the setup. With no cascade links used the maximum resolutions supported are : 1600 x 1200 @ 60Hz at 200m and 1280 x 1024 @ 60Hz at 300m.
Q: Video image at the receiver module is distorted or shadows appear to the right of displayed objects.
A: If the overall video image is "fuzzy" and/or has coloured shadows you may need to make skew adjustments. This procedure allows you to finely tune the red, green and blue video signal timings to overcome most colour separation problems. |
