INTRODUCTION Computers and HDTV video source devices can sometimes lose the EDID -- the electronic identification of a display which lists its possible resolutions and frequencies. When displays are switched away or disconnected and then reconnected, the EDID can be lost and the computer or HD video source device can lose the ability to display the image properly. The DVI Detective Plus captures a display device’s EDID and stores it.
FEATURES Features • Store EDID information for displays • Supports resolutions up to 1920x1200, 2K, and 3840x2400 (Dual Link) • Keeps computer systems from deactivating inactive DVI ports • Can eliminate CAT-5 lines used to carry DDC signals when extending computer video • Passes HDCP copy-protection protocols for full HDTV, using an HDMI to DVI adapter (not included) • No power required after initial programming Includes: (1) DVI Detective Plus (1) 1’ DVI cable (m-m) (1) 5V DC Power Supply (1)

CONNECTING AND OPERATING THE DVI DETECTIVE PLUS 1. Before proceeding, please ensure that the write protect switch is in the E (write enabled) position and all SETTING DIP SWITCHES are in the OFF (down) position Please see the diagram on the page 8. 2. Connect the display to the DVI Out port on the DVI Detective Plus. Turn on the display to ensure that an EDID is being transmitted. 3. Plug the supplied 5V DC power supply into the DVI Detective Plus.
CONNECTING AND OPERATING THE DVI DETECTIVE PLUS 5. Once a successful EDID record is complete, remove the 5V DC power supply from the DVI Detective Plus. At this time, it is recommended that you write protect the DVI Detective Plus to prevent an accidental overwrite. Please see page 9 for instructions on this procedure. 6. If HDCP is required by the source, the display must also be HDCP compliant and DIP SWITCH 4 will have to be enabled for HDCP pass through to function.
USING A PRE-PROGRAMMED EDID The DVI Detective Plus includes 5 built-in manuallyselectable generic EDIDs (display identities) for forcing several standard home theater setups with multi-channel audio and standard HDTV resolutions. This functionality is vital when equipment reaches a state of indeterminate function and will not respond to signals or controls properly, and a certain resolution size with specific audio must be forced upon all connected equipment.

PRE-PROGRAMMED EDID DIAGRAM Pre-Programmed EDID DIP SWITCHES The EDID switches on the left hand side of the unit are preset at the factory to provide the behavior shown in the chart on Page 8. This behavior can be custom fine-tuned to accomodate your audio/video displays by setting the small white plastic switches as shown in the chart. When adjusting the switches, please use gentle force.
WRITE PROTECTING THE DVI DETECTIVE Write protection switch 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.
