APPENDIX A PROBLEM SOLVING GUIDE

HUM BARS or NOISE IN THE VIDEO

1.Check video coax connectors for proper grounding

2.Check power ground for proper connection

3.Possible large ground loop fault and must use Video Isolation Transformer

VL VIDEO ERROR LED NOT ON BUT VIDEO LOOKS BAD

1.VL Video Error measures the level of the sync signal not the overall video peak to peak level. Therefore if sync signal is correct and the video level is noisy or low or high the display might be too light or too dark. In this case the addition of a video amplifier or adjustment of the camera settings might help.

VL VIDEO ERROR LED ON BUT VIDEO LOOKS GOOD

1.The VL Video Error measures the level of the sync signal not the overall video peak to peak level. Therefore it is detecting the sync signla is low and amplifying the video signal to its maximum of 2 times. In this case the sync is sufficient for the monitor or DVR to lock to and show a good image. If the inserted text from the VSI-Pro Max is stable then the VSI-Pro Max is able to lock to this low signal. If the text jitters or is skewed then a video amplifier must be placed in line with the VSI-Pro Max to bring the signal up to at least .5V P-P so the AGC circuitry can adjust to the proper output level.

FUNNY CHARACTERS OR GARBAGE ON SCREEN

MY CUSTOMER IS CHANGING REGISTERS. WILL THE VSI-Pro Max WORK WITH THE NEW REGISTER?

This is a tricky one. The VSI-Pro Max interfaces to over 400 different registers. The probability the VSI-Pro Max will work with a new system is relatively high. The chances any additional boards or boxes will work is lower, unless your customer is staying with the same manufacturer and within the same register series.

Contact AVE’s Product Support Specialists for additional help with this issue.

IF I INSTALL YOUR INTERFACE BOARD INTO A NEW REGISTER, WILL IT VOID MY CUSTOMER’S WAR- RANTY?

If you are connecting to an external RS-232 port of the register, generally it does not void the warranty. But if you want to add the interface board inside your new cash register, we will highly recommend you to contact the manu- facturer of the cash register for sometimes opening the register does void the warranty.
