1.0 Introduction
Thank you for purchasing the Hall Research EMX-DVI. Use this device to boost and
extend DVI video signals, emulate a display to the source by supporting EDID
functions, and to be able to read/learn and emulate any display’s EDID.
The EMX-DVI automatically compensates for the signal degradation caused by long
video cable runs of up to 50 ft (15 m) on its input and can drive long DVI Cables on
its output to 40 ft (12 m) by boosting and echo-canceling the DVI video output. Its
ability to equalize cable losses makes it ideal to be placed at the far (display) end of
long DVI cables.
By default, the unit is setup to buffer single link DVI (or HDMI) signals. Use the
recessed LINK pushbutton to change the mode to support Dual link TMDS signals.
There is an indicator on the top of the unit for the selected mode.
In most instances, when configured for Single Link extension, the unit can operate
from the power available through the DVI source signal and no external power
supply connection is required.
The unit ships with a universal power supply in case the power from the DVI input
source is insufficient. The power supply is plugged in at the USB connector. When
the USB port is connected to a PC (cable supplied), the unit is powered by the PC
through the USB connection.
The DDC channel (that handles EDID and HDCP data) can either be bypassed
through the EMX-DVI (so the source communicates directly with the connected
display), or it can be emulated whereby the EDID is supplied from internal memory.
The product is shipped with a fixed internal EDID table for emulate mode, but this
table can be overwritten by either learning the EDID from a connected sink (display),
or uploaded via the USB port using the free software from Hall Research. The user
can revert to the original internal table if required, by performing factory reset using
the software.
