Appendix A – Internal Jumper Settings
These modifications are only required in very
rare circumstances. Composite Sync and
Sync-on-Green are only required in RGB mode
(never Component/YPbPr mode) and typically
only with older, large front projectors. The
rule of thumb is if you are seeing a picture on
your display, then you have the sync settings
correct.
To modify these internal settings, you will
need to change a jumper that is only available
after opening up your iScan Pro unit. Read
through these instructions first and if you feel
rear panel screws
- Turn the iScan Pro unit so that the back of
the unit is facing you. Remove the two
screws on the back of the unit and set aside
in a safe place – you will definitely need
these screws later!
- Discharge yourself by touching some
grounded, heavy metal object nearby.
that you are not comfortable with performing
this type of operation, please ask your dealer
to make the modification for you. They are
generally happy to do so.
Removing the iScan Pro motherboard
- Find an electrostatic-free environment to
work at. Having no carpeting or static-free
carpeting is strongly recommended. If you
can find an area with some heavy metal
parts within easy reaching distance, touch-
ing these will allow you to discharge your-
self before beginning work.
- Pull the back panel and EMI gasket off of the
unit. The iScan Pro printed circuit board is
seated in the bottom slot in the chassis
housing.
- Pull the board all of the way out of the
housing.
