INTRODUCTION

The DVI Detective is a unique and useful little device that reads and stores a computer’s digital video information (EDID) in order to simplify the installation process for users who are extending a digital projector or plasma display away from the computer.

Plug the supplied 5V DC power supply into the DVI Detective. The power LED should be glowing solid.

Once you are ready to program the EDID, press the Program button on the front panel of the DVI Detective to initiate the recording sequence. The power LED will begin to ﬂ ash, and when it turns solid again, the programming sequence is complete.

Remove the 5V DC power supply from the DVI Detective. At this time, it is recommended that you write protect the DVI Detective. Please see the next page for instructions on this procedure.

Connect your source to the DVI In port on the DVI Detective. Note: If using a PC, restart your computer only after you’ve made all the

connections.

Before proceeding, please ensure that the write protect switch is in the E (write enabled) position. Please see the diagram on the next page.

Connect your display to the DVI Out port on the DVI Detective. Plug the supplied 5V DC power supply into the DVI Detective. The power LED

WRITE PROTECTING THE DVI DETECTIVE

Once the DVI Detective is programmed and working, you can write protect the unit to prevent an accidental overwrite. This is done by simply moving the write protect switch to the D (write disabled) position. By default, the unit is shipped in the E (write enabled) position. This is done so that the unit is ready to be programmed right out of the box. Whenever the unit is going to be programmed, make sure that the switch is in the “E” position, otherwise the procedure will fail.
