Appendix A : Problem Solving Guide - AVE VSI-Pro Max Operation Manual

PROBLEM SOLVING GUIDE
NO NETWORK COMMUNICATION OR LED FLASHING
1. Verify the RJ11, RJ12 or RJ45 is locked into the connector firmly and the locking tab no broken
2. Verify the RJ connector is crimped and wired properly, Pins 4 &5 the two in the very center.
3. Verify the unit is set to either the Master or Slave Mode
4. Verify all network modules are connected and the last in the loop terminated.
NO DATA TO THE DVR FROM MASTER
1. Verify the TX Protocol is set correctly and matches the DVR type and setting
2. Verify the DVR ComPort is enabled
3. Verify the cable from the VSI-Pro Max to the DVR is correct.
NOTE
The VSI-Pro Max requires 0.5VP-P to 2V P-P to properly overlay data on the video image
NO VIDEO ON MONITOR
1. VSI-Pro Max transformer not plugged in, or is malfunctioning.
2. Video In/Out connectors reversed, or BNC connector is not correctly wired.
3. No video input signal.
4. Bad video cable or connector.
5. Camera Iris is closed.
6. Other video device in system is off or malfunctioning.
CHARACTERS JITTER, JUMP, OR SKEW
1. Darken the gray scale of the characters.
2. The VSI-Pro Max requires the input video signal to be 0.5VP-P to 2V P-P. If the voltage is too high or low, then the
VSI has trouble syncing the text to the video. Use an amplifier such as AVE's VDA-401 or VECA to get the proper
level.
3. Poor input sync signals - too many AC coupled amplifiers in the video input signal.
4. Noisy or poor quality video source. Replace with better source.
5. Check for double termination.
6. Video level too high; VSI-Pro Max will clip video.
7. The text block is too close to the edge of the screen. Try repositioning the text block. Also, changing the size may
help.
8. Too much light in the video picture may cause character distortion. Reposition the camera or reduce the amount of
light to which the camera view is exposed. If the camera you're using has an auto iris lens, try adjusting the iris to
average and then reduce or increase the level.
NO COLOR IN THE PICTURE
1. Cable run too long and color signal too low, use AVE ARXD Active Reciever to recovery signal.
2. Cable run too long and color signal too low, use AVE VECA on the camera end to amplify the signal.
HUM BARS or NOISE IN THE VIDEO
1. Check video coax connectors for proper grounding
2. Check power ground for proper connection
3. Use the Opto-Isolation input of the Register Port and isolate the ground.(See Appendix S Page 98)
4. Possible large ground loop fault and must use Video Isolation Transformers
