VSSI-Pro VIDEO SERIAL ATM INTERFACE
FREQUENTLY ASKED QUESTIONS REGARDING ATM INTERFACING
My customer is changing ATMs; will the VSSI-Pro they have work on the new ATM?
This is a tricky one. There may be other versions of software needed to work with different ATM formats. The probability
the VSSI-Pro will work with a new system is relatively high, especially if it’s Version 11 based.
Call AVE’s Product Support Specialists for additional help along these lines.
I installed a VSSI-Pro and the On-screen text jumps or jitters.
Our VSSI-Pro text inserter requires the input video signal to be 1V P-P +/-20%, terminated @ 75 ohms. If this voltage
varies either too high or too low, the VSSI has trouble synchronizing the text to the video.
There are a couple of things you can try to help settle the text down. Change the gray scale level of the text block from
the whitest level to one of the slightly lower gray levels. Changing the size of the text block may help. Sometimes
moving the text block away from the edge of the screen may help settle the text down too.
If these don't seem to have an effect then try using a distribution amp like AVE's VDA-601 to properly adjust the video
level. If the camera you're using has an auto iris lens, try adjusting the iris to average and then reduce or increase the
level.
