INTRODUCTION
The DVI Detective is a unique and useful little device that reads and stores a com-
puter’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.
Once installed and connected, the DVI Detective continually transmits the EDID to
the computer, essentially “tricking” the computer into thinking that the video is pres-
ent, even when it is not connected. The user can then disconnect the display, place
it in a remote location and reconnect it, without rebooting the operating system. The
entire installation process benefits from the DVI Detective, which utilizes a much
smaller cable that requires fewer connections; it makes life easier for those extend-
ing digital displays or projectors. An inconspicuous device that weighs less than
one pound. The Detective can connect to a DVI port orADC port with the use of an
adapter. It works with all digital displays (DVI) as well as Apple’s line of flat panel
displays (ADC). Even analog display EDID’s can be used with the DVI Detective by
using VGA to DVI adapters on the input and output ports of the DVI Detective.

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
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 flash, 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.

WRITE PROTECTING THE DVI DETECTIVE
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.
