Adder Technology AV Series manual MaxMax, To adjust the skew compensation

To zero the skew adjustment dials When supplied, the two skew dials are set in their neutral positions. i.e. no delay to either of its colours. However, if the module has been previously used and adjusted then you may need to relocate the zero point. There are no setting markers around the two skew dials and the dial itself does not have a pointer.

1Insert a small screwdriver into the skew dial and twist it all the way anticlockwise. Note the position of the dial when it reaches its end point.

2Rotate the screwdriver fully clockwise and again note the endpoint position of the dial.

To adjust the skew compensation

Your chances of achieving a successful skew compensation adjustment will be improved if you do the following:

•Ensure that you have a clear view of one or both display screens,

•Display a suitable RGB test pattern, either the supplied pattern or a self- created version,

•Use a screwdriver of an appropriate size to adjust the dials,

•Begin with both skew dials in their neutral positions - if the module has been previously used and skew adjusted for an alternative installation, zero the dials as described in the section ‘To zero the skew adjustment dials’ left.

NOTE: AV200 receiver modules must be placed into skew compesation mode - see opposite.

3Now rotate the screw driver anticlockwise until the dial reaches the position that lies midway between the two end points. This is the neutral position.

4 Repeat this procedure for the other skew dial, if necessary.

To place the AV200 receiver into skew compensation mode NOTE: This procedure is not required for the AV101 receiver.

The AV200 receiver module shares one of its processors between the duties of operating its serial port and adjusting the skew compensation. When power is first applied to the module, it enters a neutral state for up to ten seconds signified by a fast flickering red indicator. During this time, if you move one of the skew dials, the module will enter skew mode.

1Apply power to the AV200 receiver module. The red indicator should flicker rapidly for up to ten seconds.

2Using a small screwdriver, rotate one of the skew dials slightly. The red indicator should flash slowly signifying that the module is now in skew compensation mode. Continue to make your skew compensation adjustments in the usual manner - see opposite.

3Once the necessary adjustments have been made, remove power from the module for a few seconds and then reapply. The module will automatically settle into its default serial port mode after ten seconds.

1Turn the SKEW RG dial clockwise or anticlockwise until you observe that the red and green colours are aligned.

2Turn the SKEW GB dial clockwise or anticlockwise until you observe that the green and blue colours are aligned.

3Your actions in step 2 may alter the Red/Green alignment. If so, go back to the SKEW RG dial and turn it clockwise or anticlockwise until you observe that the Red and Green colours are aligned, at which point all of the colours will be aligned.
