SAMPLE CONNECTION DIAGRAM
IR PASS-THROUGH
The system supports bi-directional IR pass-through, allowing you to control devices on
both the source and destination ends. This section provides several connection and
switching examples to illustrate possible configurations. The kit comes with four IR
receivers and four IR transmitters. Some connections require additional receivers and/or
transmitters, which will need to be obtained separately.
Control Local Input Device From Local
By default, there is a one-to-one relationship between the IR OUT port on the matrix and
the HDMI® input. When you switch an HDMI input, the corresponding IR OUT will be
switched at the same time.

13
For example, if HDMI® input 3 is connected to the HDBaseT™ output 4, plug an IR receiver
into the IR IN 4 jack and an IR transmitter into IR OUT 3, as shown in the diagram below.
The same standard applies when you have one HDMI® input connected to multiple
HDBaseT™ outputs. For example, if you have HDMI input 3 connected to HDBaseT output 2,
3, and 4, plug an IR receiver into IR IN 2, IR IN 3, and IR IN 4, then plug an IR transmitter into
IR OUT 3, as shown in the diagram below.

14
Control Local Input Device From Remote
The same basic principle applies when controlling the local input device from the remote
location. For example, if you have HDMI® input 3 connected to HDBaseT™ output 4, plug an
IR receiver into the IR IN jack on the receiver, then plug an IR transmitter into IR OUT 3 on
the matrix, as shown in the diagram below.
Similarly, you can control all local input devices by plugging an IR transmitter into the IR
OUT ALL OUT jack on the matrix. In this case, you must have an IR receiver plugged into the
IR IN jack on each of the connected HDBaseT™ receivers, as shown in the diagram below.

15
Control Remote Device From Local
You can also control the remote display from the local end. For example, if you have HDMI®
input 3 connected to HDBaseT™ output 3, plug an IR receiver into the IR IN 3 jack on the
matrix, then plug an IR transmitter into the IR OUT jack on the receiver, as shown in the
diagram below.
Similarly, you can control all remote displays by plugging an IR receiver into the IR IN ALL
IN jack on the matrix. In this case, you must have an IR transmitter plugged into the IR OUT
jack on each connected HDBaseT™ receiver, as shown in the diagram below.

16
BUTTON CONTROL
The matrix can be controlled using the buttons on the front panel. Whenever a command is
accepted by the matrix, all the buttons pressed will blink 3 times, then will turn off. If the
command fails, the indicators in the buttons will turn off immediately without blinking.
Switching
To make a single, one-on-one connection, press an INPUT button, then press an OUTPUT
button, and finally press the ENTER button. For example, to connect HDMI® input 1 to
HDBaseT™ output 2, press the INPUT 1 button, then press the OUTPUT 2 button, and finally
press the ENTER button. The indicators in the INPUT 1, OUTPUT 2, and ENTER buttons will
blink 3 times.
To make a connection between an HDMI input and multiple HDBaseT outputs, press an
INPUT button, then press multiple OUTPUT buttons, and finally press the ENTER button. For
example, to connect HDMI input 1 to HDBaseT outputs 2, 3, and 4, press the INPUT 1
button, then press the OUTPUT 2, OUTPUT 3, and OUTPUT 4 buttons, and finally press the
ENTER button. The indicators in the INPUT 1, OUTPUT 2, OUTPUT 3, OUTPUT 4, and ENTER
buttons will blink 3 times.
To make a connection between an HDMI input and all HDBaseT outputs, press an INPUT
button, then press the ALL button, and finally press the ENTER button. For example, to
connect HDMI input 1 to all HDBaseT outputs, press the INPUT 1 button, then press the ALL
button, and finally press the ENTER button. The indicators in the INPUT 1, ALL, and ENTER
buttons will blink 3 times.
EDID Management
Extended Display Identification Data (EDID) is the method by which the display
communicates its maximum resolution and audio capabilities to the source device. With
the matrix, however, there is no regular connection between a source and a display.
Additionally, a single source device can be connected to multiple displays, each of which
may have different capabilities.

17
By default, the matrix will use the EDID information from the display connected to output
1, but it may have a higher maximum resolution than another connected display, which
would prevent the other display from displaying video. To overcome this problem, this
matrix includes advanced EDID management. There are two methods for setting the EDID
information for the connected source devices. The first method is to copy the EDID
information from one of the connected displays to one or more of the source devices. The
second method is to assign a predefined EDID setting for one or more sources.
Note that by default, when copying the EDID information from one of the outputs, the
matrix will copy the EDID information from the display connected to the HDBaseT™
receiver, not from the local display connected with an HDMI® cable. If you want to copy
the EDID information from the local display instead of the display connected to the
HDBaseT receiver, disconnect the Ethernet cable from the HDBaseT output.
To copy the EDID information from one display to one source, first press the EDID button,
then press an INPUT button followed by an OUTPUT button, and finally press the ENTER
button to confirm. For example, to copy the EDID information from output 4 to source 2,
press the EDID button, then press the INPUT 2 button followed by the OUTPUT 4 button,
and finally press the ENTER button. The EDID, INPUT 2, OUTPUT 4, and ENTER buttons will
blink 3 times.
To copy the EDID information from one display to all sources, first press the EDID button,
then press the ALL button followed by an OUTPUT button, and finally press the ENTER
button. For example, to copy the EDID information from output 4 to all sources, first press
the EDID button, then press the ALL button followed by the OUTPUT 4 button, and finally
press the ENTER button. The EDID, ALL, OUTPUT 4, and ENTER buttons will blink 3 times.
The following table shows the seven predefined EDID settings.

To assign one of the predefined EDID settings to one source device, first press and hold the
EDID button for 3 seconds, then press an INPUT button, then use the LEFT (OUTPUT 2) and
RIGHT (OUTPUT 4) buttons to select one of the presets, and finally press the ENTER button
to confirm. For example, to assign one of the presets to HDMI® source 4, first press and
hold the EDID button for 3 seconds, then press INPUT 4, then use the LEFT (OUTPUT 2) and
RIGHT (OUTPUT 4) buttons to select a preset, and finally press the ENTER button. The EDID,
INPUT 4, LEFT, RIGHT, and ENTER buttons will blink 3 times.
To assign one of the predefined EDID settings to all source devices, first press and hold the
EDID button for 3 seconds, then press the ALL button, then use the LEFT (OUTPUT 2) and
RIGHT (OUTPUT 4) buttons to select a preset, and finally press the ENTER button to
confirm. The EDID, ALL, LEFT, RIGHT, and ENTER buttons will blink 3 times.
Inquiry Mode
Inquiry Mode allows you to check the connection status of the matrix as a whole or of a
single output. To enter Inquiry Mode, press and hold the ENTER button for 3 seconds.
To check the connection status, press and hold the ENTER button for 3 seconds, then use
the LEFT (OUTPUT 2) and RIGHT (OUTPUT 4) buttons to cycle through the five reports. The
following table shows examples of each of the five available reports.

GUI CONTROL
You can control the matrix using a web-based Graphical User Interface (GUI) by plugging
an Ethernet cable into the TCP/IP jack on the matrix, then plugging the other end directly
into your computer or into a switch or router on an existing Ethernet network. The matrix
has the following default IP settings:
IP Address: 192.168.0.178
Subnet Mask: 255.255.255.0
To display the GUI, open an internet browser, then type 192.168.0.178 into the address field
and press the ENTER key. You will see the following screen in your browser.
Type the User Name and Password into the appropriate fields, then click the Login button
to log into the GUI. The default User Name is admin and the default Password is also admin.
