3. Installation guide
3.1 Preparation
Set up the power supply (12 - 48 V DC). Ensure that the device can work under the specified environmental condi-
tions (operating temperature: -25 – +70 °C, humidity: 5 – 95 % relative humidity). The device should not be exposed
to direct sunlight and it should be installed away from heat sources and environments with strong electromagnetic
interference. The router is mounted on a DIN rail (mounting rail).
3.2 Mounting the device
Mounting rail:
Select a position on the rail with enough space. Then, position the upper part of the DIN rail mount on the mounting
rail. Following this, press the lower side of the DIN rail mount down until the device is locked.
This is shown in this image:
In order to remove it, press the device from top to bottom and then pull the underside of the device from the DIN
rail (see illustration).

4. SIM card installation

The TK800 supports dual SIM. For insertion of the card, press the yellow “Eject” button on the top of the device, e.g.
with a small screwdriver. The respective SIM card slot will be pushed out. Then, insert the SIM card as shown in the
illustration.
5. Antenna installation
Connect the antennas to the SMA connectors and tighten the outer fixing on the antenna cable until the connection
is tight.
The TK800 has two antenna connectors, which are labeled ANT and AUX. The ANT port is used for data transmission, while the AUX port is only used to
! stabilize the signal. Therefore, AUX cannot transmit data and it cannot be used separately. Please use the ANT port and, should you have poor signal strength,
connect a second antenna to the AUX port.

6. Power supply installation

Remove the port block from the top of the router. Unscrew the relevant screws on the port block and thread wires to
the relevant ports. The ports are marked accordingly on the top of the router. Then, retighten the screws and plug
the port block back into the router.
In order to ground the device, use the grounding screw on the device.
! In order to eliminate interference with electromagnetic effects, the casing of the router must be grounded using the grounding screw.
7. Cable connection
Connect the router to the PC via network cables.
8. Connection of the serial interfaces and I/Os

In order to connect the serial interfaces and I/Os, a terminal block can be found on the front panel of the device. In-
dividual contacts for this are labeled on the front panel of the device. Connect the lines to their corresponding labels.
Here, the “IN” contact represents the digital input, and the output contact is labeled “Relay”. “COM” represents the
ground. During installation, please unplug the terminal block from the device and connect the individual wires to the
corresponding ports. Then, plug the terminal block back into the device.

9. Starting up the router

9.1 Automatic configuration (DHCP)
Configure the PC to act as a DHCP client (automatically obtain IP address). Connect the PC to the FE0/1 or FE0/2 port
with a network cable. In this way, the IP address, default gateway, and DNS server are assigned by the router to the
PC. The following image shows the configuration sequence through DHCP on a PC running a Windows 7 operating
system and using the FE0/1 or FE0/2 port.
After configuring the PC IP address and the router connection, open a web browser and type “http://192.168.2.1”
into the address bar field. After pressing the “Enter” key, a pop-up appears as the router login page. Enter the
username (default: “adm”) and the password (default: “123456”) and confirm by pressing “Enter”. You will now be
redirected to the configuration page. You can now configure the router to your requirements.
In order to check that you are connected to the Internet, select “Network”  „Cellular“  „Status“ in the naviga-
tion panel. From here, you can see the cellular radio unit of the router. As an alternative, you can simply open a web
page in your browser.
IP: 192.168.2.1
Username: adm
Password: 123456

9.2 Manual configuration
Configure your PC so that it is in the same subnet as the router (192.168.2.1). The default subnet mask is 255.255.255.0.
The following image shows the process for configuring the IP address on a PC running a Windows 7 operating sys-
tem.
After configuring the PC IP address and the router connection, open a web browser and type “http://192.168.2.1”
into the address bar field. After pressing the “Enter” key, a pop-up appears as the router login page. Enter the
username (default: “adm”) and the password (default: “123456”) and confirm by pressing “Enter”. You will now be
redirected to the configuration page. You can now configure the router to your requirements.

Watchdog picks up
Watchdog monitors the router in regards to its Internet connection. The router even checks if the Internet connection
is established. For this reason, it sends ICMP packets to an individually defined server (ICMP detection server). If this
query fails, the router will firstly start up a new dial-up automatically, then restart the modem, and if necessary, reboot
the entire system.
Watchdog provides a reliable Internet connection in the mobile network. This ensures that the router is almost always
available.

The new rule is now active. The corresponding services restart and the port mapping is completely set up.
In order to achieve an efficient port mapping, it is helpful to check the settings of the connected devices in advance.
The following checklist is helpful (following the example above):
• Does the camera have the IP address 192.168.2.2?

• Does this respond to “ping 192.168.2.2”?
• Is the camera web interface reachable via http://192.168.2.2?
• Is the camera configured with the Welotec router as its standard gateway (192.168.2.1)?
