TROUBLESHOOTING GUIDE 10
1. The power, LED should be ON when the
correct voltage is applied to Interface.
2. The Termination dipswitch should be in the
ON position if no Y cable (breakout) is used
on the input.
3. Make sure that the cables have the correct
pin-outs and the connection and quality of the
cables are good.
4. Make sure that the source and display are
scan-rate compatible. The projector should
support an appropriate signal format (RGsB,
RGBS or RGBHV). Connect the projector
directly to a computer with a shorter cable to
verify the compatibility of the display and the
source.
5. If you are using output RGBS or RGsB then
the HV Output dip-switch is in the OFF
position and the composite sync signal is
taken from the sync connector. If the display
needs an RGBHV signal then the HV Output
dip-switch should be ON if sync and vertical
connectors are used.
6. If the desired output is RGsB then the Sync
on Green dipswitch should be ON.
