Hardware Installation
1. Power off all devices including your HDMI source
and HDMI display(s).
2. Connect your HDMI source device to the
Transmitter's HDMI In connector with an HDMI
cable (HDMI cable is not included).
3. Connect your CAT cables between the Transmitter
and CAT6/7 Receivers.
4. Optional: Connect an HDMI display to the HDMI
Out connector of the Transmitter using an HDMI
cable (HDMI cable not included). This connection
is needed only if you require local monitoring of
the HDMI signal.
5. Connect an HDMI display to each CAT6/7
Receiver's HDMI Out connector with an HDMI
cable (HDMI cables not included).
6. Optional: Connect the IR Receiver cables and the IR
Emitter cables to the IR interface ports. The IR
feature is bi-directional so either the source device
or the display device(s) can be remotely controlled.
See IR Control, on page 9, for proper IR connection.
7. Plug the included 12V/2A power adapter into the
Transmitter's Power Jack, then plug the power
adapter into a reliable power outlet. Note: Only 1
power adapter, connected to the Transmitter, is
needed to power all Receivers over CAT cables.

IR Control
Provides IR control of the connected devices. The IR
feature is bi-directional so either the source device or the
display device(s) can be remotely controlled.
Controlling the Source Device
1. Connect an IR Emitter Cable to the IR Out port of the
Transmitter.
2. Point the IR Emitter Cable's IR eye in line with the
source device's IR window.
3. Connect an IR Receiver Cable to the IR In port on
each CAT6/7 Receiver.
Controlling the Display Device(s) using IR In
Allowsyou to remotelycontrol each displayindividually.
1. Connect an IR Receiver Cable to the IR In port of the
Transmitter.
2. Connect an IR Emitter Cable to the IR Out port on
each CAT6/7 Receiver.
3. Point the IR Emitter Cable's IR eye in line with the
display's IR window.
Note:
The Transmitter's IR Out connector will output the IR
signals received from any of the CAT 6/7 Receivers, so
as to allow control of a source from any of the remote
CAT 6/7 Receivers.

EDID Management
EDID is used by the source device to match the video
resolution to the connected display(s). However, since
displays with different capabilities are often connected,
the EDID DIP switch can be used to set the EDID to a fixed
value to offer the best compatiblity accross all connected
displays.
DIP Switch
The splitter supports EDID management through a 3-pin
DIP switch.
Switch Up for "0"
Switch Down for "1"

• With a computer as a source device, restart the
computer after making changes to the EDID setting
• Copy EDID option can only be used with displays
maxing out at 4K@60Hz. EDID copy of displays
with higher resolution than 4K@60Hz, such as 8K or
