INTRODUCTION

Congratulations on your purchase of the HDMI Detective Plus. Your complete
satisfaction is very important to us.

Gefen

Gefen delivers innovative, progressive computer and electronics add-on solutions
that harness integration, extension, distribution and conversion technologies.
Gefen’s reliable, plug-and-play products supplement cross-platform computer
systems, professional audio/video environments and HDTV systems of all sizes
with hard-working solutions that are easy to implement and simple to operate.

The Gefen HDMI Detective Plus

Computers and HDTV video source devices can sometimes lose the EDID -­(which is basically the electronic identication 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 HDMI
Detective Plus product allows you to switch or relocate HDTV or Computer video
displays while “tricking” the source devices into thinking that the display is still
present -- maintaining smooth video operations throughout the process.

How It Works

The Gefen HDMI Detective Plus attaches to the HDTV display’s HDMI input
connector for initial programming. Power is applied and the HDMI Detective Plus
reads and stores the attached displays EDID to the internal memory. Then the
HDMI Detective Plus is attached to your source HDMI output and it will never

lose EDID again.

The HDMI Detective Plus includes 4 built-in selectable generic EDIDs that can be
used for meeting standard home theater setups. They can be selected by moving

the dip switches between the different settings.

How to Connect the HDMI Detective Plus

1. Power-on the display (or other sink device) containing the EDID to be

recorded.

2. Use an HDMI cable to connect the sink device to the HDMI Out port on the

HDMI Detective Plus.

3. Set all four DIP switches in the OFF (up) position, as shown in the illustration

below.

4. Set the WR (Write) switch to the “E” (enable) position to allow the HDMI
Detective Plus to be programmed.

5. Connect the included 5V DC power supply to the HDMI Detective Plus. The

power LED will glow bright green if the sink device contains a valid EDID.
If the sink’s EDID is corrupt or invalid, then the power LED will glow bright

red.

6. Press and hold the Program button on the front panel of the HDMI Detective

Plus until the power indicator begins to rapidly ash bright green, then
release the Program button. The power LED will continue to ash as the

EDID is written to the HDMI Detective Plus.

A successful recording will be indicated with a solid green LED. If the
recording process was unsuccessful, the LED will glow bright red.

6. Remove the 5V DC power supply from the HDMI Detective Plus.

7. Set the write-protect switch to the “D” position (enable) in order to prevent an
accidental erasure of the stored EDID.

8. Use the included HDMI cable to connect the source to the HDMI Detective
Plus.

9. Apply power to the source.

If a computer is being used as the source, restart the computer only after all
connections have been made.

CONNECTING THE HDMI DETECTIVE PLUS

IMPORTANT: If the source uses HDCP, then DIP switch 4 must be

enabled in order to enable HDCP pass-through. In this case, the

display must also be HDCP-compliant. Refer to your source and
display manuals for HDCP compatibility.

NOTE: If the HDMI Detective Plus does not initiate the recording

sequence, indicated by a ashing green LED, unplug the display
and 5V DC power supply from the unit and repeat steps 2 and 3.
If a solid red LED is indicated after several unsuccessful recording
attempts, it is possible that the EDID from the display is bad. In this

case, see page 8 for instructions on using a built-in EDID.

“E” (enable write) position and make sure all DIP switches are in the OFF

position.

2. Use an HDMI cable to connect the source (generator) device to the HDMI In
port on the HDMI Detective Plus.

3. Connect the included 5V DC power supply to the HDMI Detective Plus.

4. Use the source (generator) device to send the EDID data to the HDMI
Detective Plus.
