7.3 Connection and first use
First, switch off all devices (signal sources and display devices) that you want to connect
to the HDMI switch.
Connect the output plug on the power adapter to the „DC 12V" input (7) on the HDMI switch
and tighten the lock nut.
Use an HDMI cable to connect the desired HDMI sources (e.g. PC, games console, Blu-
ray/DVD player, etc.) to the „IN 1" to „IN 4" HDMI inputs (5).
Now connect the desired HDMI display devices (e.g. monitor, HD TV, UHD TV, projector,
etc.) to the „OUT 1" to „OUT 4" HDMI outputs (6) with an HDMI cable.
If the HDMI display device does not have any speakers, you can also extract the audio
signal separately and transfer it to another audio device via the two audio outputs („ OUT
1" to „ OUT 4"). Alternatively, you can simply loop through the signal.
If you want to use active loudspeakers, you can connect them directly to the respective
audio output „ L/R" (12) of the corresponding channel („ OUT 1" to „ OUT 4").
If you want to connect an audio device (e.g. an amplifier) with a coaxial digital input, con-
nect it to the „COAX" output (11) of the desired output („OUT 1" to „OUT 4").
To loop through the audio signal, connect your audio device (e.g. your surround receiver
with HDMI input and output), depending on the required application, either between an
output from the HDMI switch and the display device or an input from the HDMI switch and
the signal source.
If you want to hide the HDMI switch, connect the additional IR cable to the „IR EXT" socket
(10) on the switch. Position the sensor in such a way that you have a line of sight with the
remote control.
Finally, check all cables again to make sure they are connected properly.
Plug the power adapter into a mains socket. The HDMI switch will start automatically and
switch on when it is supplied with power.
Take the remote control and pull out the plastic strip.

8 Operation via the device and the remote control
When the HDMI switch is on, you can switch through the „IN 1" to „IN 4" HDMI inputs for the
respective HDMI output via the corresponding button on the front of the device (4).
The corresponding green status LED indicates which HDMI input is currently active.
You can also use the same function on the remote control via the two arrow keys for the
respective channel.

Alternatively, you can directly select the corresponding HDMI input on the remote control
4
via the 1/2/3/4 buttons for the respective channel.

9.1 Connection
The switch and the compatible devices con-

Connect the 9-pin plug directly to your comput-
er or use an RS232 USB adapter.

9.2 Control commands (ASCII)
The list of control commands for the serial interface can be found in a separate document
in the download section of our website.
10 Configuration and operation via the web interface
The HDMI switch can be configured and also operated via the web interface. Some functions
are only available via the web interface.
You can integrate the switch in your existing network or connect a computer directly via a
network to the HDMI switch. In the second case, a fixed IP address must be assigned to the
LAN connection on the PC.
10.1 Integrating into an existing network
DC 12V
Use a 1-to-1 network cable to connect the „TCP/IP" connection (8) on the HDMI switch to
a LAN port on your router or network switch.
Switch on the HDMI switch and wait until the operating system has finished loading. If the
switch is already switched on, disconnect it briefly from the power supply.
Open the configuration page for your router and check in the network or DHCP overview
which IP address has been assigned to the HDMI switch.
10.2 Direct connection between PC and HDMI switch
Use a 1-to-1 network cable to connect the „TCP/IP" connection (8) on the HDMI switch to
a LAN port on your computer.
Switch on the HDMI switch and your computer and wait until the operating system has
finished loading.
To assign a fixed IP address to the LAN connection, you must edit the properties of the
respective interface. There are various ways to do this.
The easiest way is to press the „Windows key + R key" combination to run a command.
Alternatively, right-click the Windows icon and select „Run".
Enter the command „ncpa.cpl" and click OK.
A window will open showing all the network connections of your PC. Right click on the
corresponding connection and select „Properties".
Click „...(TCP/IPv4)" and then on „Prop-
erties".
