5V DC
Before using the DVI Detective, the unit must be programmed with an EDID. In most
cases, the DVI Detective should be programmed with the EDID of the display (or other sink
device) to which you are connecting the source. Once programmed, the EDID data will be
read by the source, providing all the necessary details of the type of signal that the display
(or other sink device) can process. Although any DVI Detective can be programmed with
any EDID, the display (or other sink device) must be able to support those features.
Basic Operation
1. Begin by powering-on the display (or other sink device) containing the EDID
to be recorded.
2. Connect a DVI cable from the sink device to the DVI Out port on the DVI Detective.
3. Move the WR switch to the “E” position in order to allow the EDID to be written
to the DVI Detective.

6. Once the EDID has been recorded, the Power LED will glow bright red.
7. Move the WR switch to the “D” position to prevent accidental erasure of the EDID.
8. The EDID programming process is complete.
