4.1 Connecting the Inputs to the Distribution Amplifier
You can connect any HDMI compliant device’s output to the HDMI input. Make certain
that the HDMI cable is securely plugged into the source device as well as the HDMI DA.
Always use a high quality cable, as short a length as possible, for best results.
4.2 Connecting the Outputs to the Destination Devices
Using a high quality HDMI cable, connect the output of the HDMI DA to a HDMI
compliant display devices. Use the shortest cable runs possible.
4.3 Connecting Power
All units are shipped with a Power Adapter to convert 100~240VAC@50-60Hz to 5VDC.
Connect the DC Output Cable from the Power Adapter to the unit and then plug the
Power Adapter into an AC receptacle. There is no power switch. The unit begins to
function as soon as it is plugged into AC.
5.0 OPERATING THE HDMI DISTRIBUTION AMPLIFIERS
Once the input, output and power cables are connected, plug the AC adaptor into the
wall and the Distribution Amplifier will begin to function. A power LED on the unit will
confirm power is present.
On the rear of the units, you’ll find a Mini USB port used for
factory service. Other than connecting cables and applying power, there are no other
routine operator interventions required.
SERVICE Port:
2
This Mini-USB port is reserved for factory service only.
EDID Operation:
When first powered on, the distribution amplifier will detect and store the EDID from
HDMI output port 1 and it will send
that output’s display format information to the
connected source. The distribution amplifier retains in memory the last EDID decision it
made, therefore the device will use the last EDID it stored if output port 1 is not
connected to a display after being power cycled.
* The Extended Display Identification Data (EDID) is a data structure provided by a
computer display to describe its capabilities. It
’s what enables the HDMI DA to know
what kind of monitor is connected to the unit. EDID is defined by a standard published
by the Video Electronics Standards Association (VESA). The EDID includes
manufacturer name, product type, phosphor or filter type, timings supported by the
display, display size, luminance data and (for digital displays only) pixel mapping data.
