The DA1226AT will operate successfully as long as cables are attached
correctly and other technical specifications are followed. There are no
other adjustments necessary to operate the unit.
8. Troubleshooting Guide
We have carefully tested and have found no problems in the supplied
DA1226AT. However, we would like to offer suggestions for the following:
•
Please make sure that the input amplitude of the analog signal is less
than 1.5Vp-p.
•
Please make sure that sync levels at the TTL level are between
1.4 and 5 Vp-p.
•
Please make sure that the highest quality of cables is used. We
recommend ALTINEX made cables for best results.
•
If a problem arises after continuous usage at a higher voltage, higher
temperature, higher humidity, or at other extreme environmental
conditions, please correct the problem.
NOTE:
The sync pulse voltage must be at least 1.4 V for proper
operation of the distribution amplifier. If lover voltage is
used, contact ALTINEX for additional information.
•
If there is no image on the display, make sure that the source has a
compatible refresh rate and resolution with the display by a direct
connector of the source and display.
•
If the image quality is poor, then check the input of the cable so that
the source is capable of driving signals to the DA1226AT through the
length of the cable.
•
If you are using a HD-15 to 5-BNC cable to connect a computer
directly to the DA1226AT and do not see the picture or display use an
interface to make the video signal compatible to display.
