American Dynamics AD - SpeedDome Ultra 8 - V-code error
V-code is one of two things, video problems or RS422 PTZ problems
After the SpeedDome power up test was done it looks for the network and displays ( Checking Network type ) I hit the pan control to send data so the speedDome can find the network. it then displays EIA422 then V-code.
The problem looks to be the cat5 cable I am using, which is at about 800 feet.
Also when the test button on the speedDome base is pressed it does go green.
I wired a box of cat5 to a speedDome next to the DVR and tested when it would fail.
the cat5 worked at 1,300 feet and failed at 1,800 feet, the camera in the field failed at 800 feet.
Also when I called tech support about this problem he said that he has had calls about v-code/PTZ problems when cat5 is used
Lesson, CAT5 and RS422 not a great match.
