Problems

If you've tried all these and the DMX still doesn't work, you may have
interference problems. Check where your DMX cables run - if they are near
or run alongside high voltage cables, power lines, or neon, you may experience
problems. The VR has protection circuitry on its DMX inputs and may
temporarily disconnect itself from the line if it detects high voltages or
interference. Try running a short DMX cable directly from the controller to the
VR.
Colours or gobos do not match the controller or other VR's
Check the "CE" option. If this option is On, the VR uses different control
values.
Mirror moves incorrectly; part colours or gobos displayed
Check the mirror invert options and the colour and gobo snap options. If the
unit is behaving strangely, you (or someone else) may have accidentally changed
some of the options. You can set all the options back to "normal" by selecting
the OPC option, then holding down the middle button.
Display sticks on "---" or shows "LIN ERR" at startup
Try turning the unit off and on again. This display indicates that the electronics
modules have not started up properly for some reason. This can be caused by
noisy mains or electrical interference in the area of the scan.
If the display shows other codes, or does not come on, this indicates a fault in
the display board.
If still you cannot resolve the problem, it may be that the VR has a fault. You
should contact your Abstract dealer for assistance. If you have Internet access
you can go to the Abstract web site:

which has a technical help page.

Using control functions
Control functions allow you to start the Reset and Test functions which are built
in to the VR.
VR soft reset
RST
_
Hold down the middle button for 3 seconds to reset the VR (this reinitialises all
the motor positions). The VR will display "INI" while it resets. This does not
reset the software - you should power off the unit to do this.
Option clear
OPC
_
Hold down the middle button for 3 seconds to clear all options back to default
states. The VR displays "EEI" while resetting the options. This does not affect
the timers or operation counter.
Function test routine
tSt
_
Press the middle button to start the test routine, which operates all the motors
to test for correct operation. The unit cannot detect correct operation, it is up
to the user to observe the test. The unit pans fast, then slowly, tilts fast then
slowly, then operates the colour and gobo wheels. Only full colours and full
gobos should be displayed if the unit is operating correctly.
At the end of the test, the VR will remain with the beam exactly centred in
open white until you press a button. This can be useful for physically aligning the
VR when rigging a show.
