3. Installation
3.1 Installing the Splitter
• Before installation, power off all devices that will be connected
to this system.
• Make sure that all devices you will connect are properly grounded.
• Place cables away from fluorescent lights, air conditioners, and
machines that are likely to generate electrical noise.
You will need one HDMI male-to-male cable to connect a video
source to the video splitter’s input port. Connect multiple monitors
or TVs to the video splitter’s output ports.
Turn on your video source only after you’ve made all the
connections.
NOTES:
1. The splitter unit is HDCP compliant and required to use
an HDCP compliant display when it is connecting to the HDCP
video source.
2. Each output port on the splitter must apply the same connection
pattern when a DVI-to-HDMI (or HDMI-to-DVI) adapter is used
for HDMI (or DVI) signal conversion between the splitter and the
HDMI (or DVI) display. Mixed (HDMI and DVI) output
connections may cause signal degradation.
3.2 EDID Configuration
Incorrect EDID communication between the display monitor and
the PC graphics card or insufficient EDID data programmed by
display manufacturers may cause problems. The splitter provides
many ways to read EDID information from the attached video
display and then provides it at all times to the attached video
source. If no new EDID information is available from a display,
the splitter automatically uses a default profile.
To efficiently achieve EDID communication when the video source
is booting up, configure the EDID on the splitter before operation.
3.2.1 EDID Copy
Step 1
. Connect the monitor (EDID compliant) to the video output
Port 1 on the splitter and power on the monitor.
Step 2
. Press the “EDID COPY” button, then release it RIGHT
AFTER the LED flashes GREEN (about 3 seconds).
Step 3
. The LED returns to normal status indicating that EDID copy
is completed.
Otherwise, if the Status LED flashes RED, it means that:
a. The monitor is not properly connected.
b. The monitor is not powered on.
c. EDID data of the monitor is not applicable.
3.2.2 EDID Factory Default Setting
T
o set the EDID copy to factory default:
Step 1
