APPENDIX H: Sync Modes
Appendix H. Setting Sync Mode
The AC1005A-R3, AC1213A, AC1006A-R3, AC1212A, AC1015A-R2 have the
capability for fixed and agile sync. The default sync mode setting is for agile sync which
replicates the source sync polarity signals. However some displays require a fixed sync
polarity that is not possible to change at the video source.
1080P signals may also require this mode if the sync is a very narrow pulse.
The following details jumper settings to change the sync polarity of the horizontal and
vertical sync signals
(Note that jumpers have no affect in agile mode):
