Safety instructions:
⦁ The installation of the device and repair work on the device must be carried
out only by a professional in accordance with the applicable VDE directives.
In case of incorrect installation, no liability is assumed.
⦁ Never open the device. There are no parts to be maintained by the user
inside the device, however, lethal voltages are present. This also applies to
cleaning the device or working on the connections.
⦁ Use only the mains cable connected to the device or the enclosed power
supply unit. Never replace any parts or make any modifications to the mains
cable and the power supply unit. Otherwise, there is a risk of death.
⦁ If a replaceable fuse is available, pull out the mains plug before replacing the
fuse. Replace defective fuses only by standardized fuses with the same
nominal value.
⦁ If you intend not to use the device for a longer period of time, we recommend
you to completely disconnect the device from the mains for safety reasons
and for saving energy by pulling out the mains plug.
⦁ Let the device adjust to the room temperature before commissioning, in
particular if condensation is present on the device, or if it was exposed to
large temperature fluctuations.
⦁ The device must be operated only in moderate climate.
⦁ The device must be operated only in dry rooms. In damp rooms or outdoors,
there is a risk of short-circuits (attention: risk of fire) or electrical shocks
(attention: risk of death).
⦁ Plan the mounting or installation location such that you can easily reach the
mains plug and interrupt the electric circuit in dangerous situations. Select the
mounting or installation location such that children cannot play near the
device and its connections without supervision. The mounting or installation
location must allow a safe installation of all connected cables. Power supply
cables and supply cables must not be damaged or squeezed by any objects.
⦁ Select a mounting or installation location which meets the requirements of the
IP 54 protection class. Operate the device only on a flat, firm surface and
protect it against unintentional movements.
⦁ Never expose the device to direct solar irradiation and avoid direct vicinity of
heat sources (e.g. heaters, other electrical appliances, fireplace, etc.). It must
be always ensured that devices with cooling elements or ventilation slots are
not covered or obstructed. In addition, ensure generous air circulation around
the device. This will prevent possible damage to device and risk of fire due to
2
overheating. It must be always ensured that cables are not located near heat
sources (e.g. heaters, other electrical appliances, fireplace, etc.).
⦁ The device is intended for transmission of audio and video signals via LAN
cable. Misuse of the device is expressly prohibited.
⦁ In particular, the warranty and liability shall be excluded for the consequences
of incorrect use, in case of incorrect modifications or repair work carried out
by the customer. Use the device only as described in the operating
instructions and in particular according to the state-of-the-art.
⦁ The antenna system must be installed and grounded according to the current
DIN EN 60728-11 standard.
⦁ The product complies with the directives and standards for CE labeling.

⦁ HDMI installation
The HKM-4002 has four HDMI inputs. Connect them to four HDMI sources.
⦁ RF Output
Connect the output of the HKM-4002 to the existing DVB-C / DVB-T distribution. Use
shielded coaxial cables with F connectors. You can find suitable cables and
connectors in the current AXING catalog or at www.axing.com.
If you are using more than one HKM-4002, the outputs must be connected with
suitable combiner.

The HKM-4002 have a built-in power supply (100 ... 240 VAC / 50 ... 60 Hz).
⦁ Do not connect the device unit until all assembly and installation work has been
completed.
⦁ Use the supplied power cord.
7
⦁ Connect the power cord to an appropriate wall outlet.
⦁ Configuration
The device is configured via the graphical user interface of the integrated web
interface.
To access the user interface, you need a standard PC/laptop with a network
interface and the actual version of the installed web browser. To connect the network
interface of the device to the computer, you need a commercially available network
cable.
The HTTP protocol is used for communication allowing a worldwide remote
maintenance of the systems at various locations via the Internet. Access protection
is implemented by means of the password prompt.
The following values are preset ex factory:
⦁ IP address: 192.168.0.168
⦁ Subnet mask: 255.255.255.0.
The computer and the headend must be in the same subnetwork. The network part
of the IP address of the computer must be set to 192.168.0. and the subnet mask
must be set to 255.255.255.0.
The host part of the network address is required for the identification of the devices
and can be assigned in the subnetwork only once. You can allocate to the computer
any not allocated host address between 0 and 255.
Hint:
Change the IP address and the subnet mask of your computer accordingly. (e.g.: IP
address:192.168.0.11 and subnet mask: 255.255.255.0)
Control panel > Network connections > LAN connection >Properties > Internet
protocol version 4 TCP/IPv4 > Properties > Use the following IP address:
⦁ Click OK to save.

⦁ Login
⦁ Start your web browser and enter the IP address of the device: 192.168.0.168.
The web-based user interface is protected against unauthorized access. When
accessing the user interface, the first thing is the password request.
⦁ Enter the default password: Ramsen8262.
Changing the password:
⦁ Please change the password immediately after the first commissioning and
choose a sufficiently safe password. Keep this password at a safe place.
⦁ Menu item: System > Set password (see 3.6.6 on page 20).
Notes:
⦁ If the browser is closed while you are still logged in, an automatic logout occurs
2.5 minutes later.
⦁ If the browser window stays open, there is no automatic logout. It allows
monitoring the installation via the web browser.
⦁ RF settings
⦁ Click RF on the main menu.
Depending on the modulator selected, the RF PARAMETERS for DVB-C or DVC-
T are displayed.
⦁ How to select the modulator type is described under 3.6.7 Modulator Type on

Depending on the selection made, the country-specific channels are displayed in
9
the Frequency field.
⦁ Select an output level of 85 ... 105 dBμV in the Output level selection field.
⦁ The symbol rate between 1000 and 7500 can be freely set in the Symbol Rate
field. The default value is 6900. Some networks also work with 6875. If working
with only 7MHz bandwidth, a symbol rate of 6111 is in use.
⦁ In the Constellation selection field, select the desired output modulation (QAM
16/32/64/128/256).
QAM256 provides the highest data transfer rate, but also requires the best
network quality.
