EMX-DVI Extender & EDID Mgr
4.0 Default EMULATION resolutions
The following lists the default resolutions of the EMX-DVI. The user can overwrite the default
EDID table but upon performing a Factory Default reset, these values reset.

5.0 Power Requirements
This device requires 5 Volts DC which can be sourced from the included power supply or PC
through the mini-B USB connector or from Pin 14 (+5 V) of the DVI connector.
To power the EMX-DVI from the DVI input power, the source must be able to supply a
minimum of 120 mA (@ 5 vDC) for SINGLE LINK DVI operation and a minimum of 220 mA
(@ 5 vDC) for DUAL LINK DVI operation. Using a video source with insufficient power
capabilities will result in erratic operation and loss of video. If this happens, the user must
connect the USB port to a PC or a power supply.
6.0 Operation
The EMX-DVI recessed buttons prevent inadvertent changes to its settings.
Change the settings requires a pointed device (such as a paper clip) inserted into the hold to
depress the button. Some functions require depressing the button for several seconds.
•EDID/DDC – PASS-THRU LED
oEDID & HDCP information passes through the device without modification.
oHDCP is supported in this mode if the connected LCD is HDCP compliant.
oHot-plug signal from connected LCD passes to the DVI input.
•EDID/DDC – EMULATE LED
oEmulates the EDID currently stored in the device.
oHDCP is not supported in this mode (perfect to MacBook™ Pro)
oHPD signal remains active (no monitor required)
•LINK – SINGLE LED
oDVI video passes through the device in SINGLE LINK format.
•LINK – DUAL LED
oDVI video passes through the device in DUAL LINK format.
