Installation Guide¶

Preparations¶

Prepare the power supply (12 - 48 V DC). Make sure that the device can operate under the specified environmental conditions (working temperature range -25 – +70 °C, humidity: 5 – 95 % relative humidity). The device should not be exposed to direct sunlight and should be installed away from heat sources and environments with strong electromagnetic interference. The router can be mounted on a DIN rail (top-hat rail) or used at a workstation.

Mounting the Device¶

DIN rail:

Select a position with sufficient space on the DIN rail. Then place the upper part of the DIN rail mount on the DIN rail. Subsequently, press the lower side of the DIN rail mount down until the device is locked in place. This picture serves as an illustration:

For demounting press the device from top to bottom and then pull the lower side of the device from the DIN rail (see figure).

Installing the SIM Card¶

The TK800 supports dual SIM. To insert the cards, press the yellow “Eject” button with a small screwdriver on the top of the device, for example. The respective SIM card slot is pushed out. If the TK800 is not operated in dual SIM mode, use the SIM card slot “SIM1”.

Then insert the SIM card. The SIM card slot is not hot-pluggable. The router must be restarted after inserting the SIM card.

Antennas Installation¶

Plug the antennas onto the SMA connectors and turn the external attachment on the antenna cable until the connection is tight.

For optimal performance, place the antennas at least 20 cm apart.

Installation of the Power Supply¶

Remove the terminal block from the top of the router. Loosen the corresponding screws on the terminal block and route the wires to the corresponding terminals. The terminals are marked accordingly on the top of the router. Tighten the screws and then reinsert the connector block into the router.

To ground the device, use the grounding screw on the device.

To prevent interference due to electromagnetic influence, the housing of the router must be grounded via the grounding screw.

Cable Connections¶

Connect the router to your PC via a network cable (RJ45). We recommend port FE 0/2 for all TK8x2 models and port FE 1/4 for all TK8x5 models.

Connection of the Serial Interfaces and I/O’s¶

For the connection of the serial interfaces and the I/O’s you will find a terminal block on the front of the device. The individual contacts for this are labeled on the front of the device. Connect the lines according to these labels. The “IN” contact here represents the digital input, while the output is labeled “Relay”. “COM” represents the ground. This is a potential-free contact, i.e. what you put in at the IN contact comes out again at the relay contact, provided the contact is closed. Switching can be done via SMS and via the web interface. At 230 VAC the contact can be loaded with 2 Ampere. During installation, please remove the connection block from the device and connect the individual wires to the corresponding terminals. Then plug the connection block back onto the device.

This chapter describes only routers in the versions with serial interfaces and I/Os TK8XXX-EX.

Startup of the Router¶

Automatic Configuration (DHCP)¶

Configure the PC so that it works as a DHCP client (obtain IP address automatically). Connect the PC with a network cable to the interface FE0/2 or FE1/1 - FE1/4 (TK8X5 variants only). The PC is then assigned an IP address, standard gateway and DNS server by the router. The following figure shows the configuration process via DHCP on a PC with the Windows 10 operating system. The settings can be accessed via the Network and Sharing Center in Windows 10.

DHCP DHCP

After configuring the IP address of the PC and connecting to the router, open a web browser.

Then enter “http://192.168.2.1” in the address line of your browser (e.g. Google Chrome). After confirming with the “Enter” key, a pop-up appears as the login page of the router. Enter the username (default: “adm”) and password (default: “123456”) here and confirm with “Enter”. Now you will be redirected to the configuration web page. Now configure the router according to your requirements.

To check if you are connected to the Internet, select Network > Cellular > Status from the navigation panel. Here you can see the data of the cellular unit in the router. Alternatively, simply open a web page in your browser.

Click Restore Default Configuration to reset the TK800 to its default settings.
After a few seconds you will receive the following message. The router has now been successfully reset.
After clicking reboot the router reboots to factory defaults.

Watchdog¶

Self Monitoring of the Router¶

The watchdog monitors the router with regard to the Internet connection. The router itself checks whether there is an Internet connection as required. For this purpose, it sends ICMP packets to an individually defined server (ICMP detection server). If this query fails, the router first automatically restarts the dial-up, then the modem, and if necessary the entire system. The watchdog ensures a reliable Internet connection in the mobile network. This ensures that the router is almost always available.

Go via the menu item Network to the submenu item Cellular.

Cellular

Select the Cellular tab

Cellular

Now enter a suitable ICMP Detection Server in the corresponding field and change the ICMP Detection Interval.

ICMP

Note: The registered ICMP detection server should have a very high accessibility. A server from Google is no longer suitable for this, since the ICMP requests are blocked there.

Port Mapping / Port Forwarding¶

Access to Connected Devices via the Internet¶

To access devices connected to the Welotec router via the Internet, port mapping or port forwarding can be used. This is configured in the TK800 router via NAT rules.

Port mapping requires a public IP address in the mobile network (Public IP). If necessary, ask your mobile network provider or service provider about this!

The instructions refer to all TK800 routers with firmware 1.0.0.r10406 or higher.

The following image illustrates the application example (http uses TCP port 80 by default):

Private network (LAN)		Public network (WAN)

Port Mapping

Package source: 1.2.3.4.8080 Destination: 192.168.2.2.80		Package source: 1.2.3.5.8080 Destination: 1.2.3.4.8080

Explanation:

Welotec Router
LAN IP address:	192.168.2.1
Subnet mask:	255.255.255.0

IP camera
LAN IP-Adresse:	192.168.2.2
Subnet mask:	255.255.255.0
Standard Gateway	192.168.1.1

The IP camera has an interface that can be reached with a browser via http://192.168.2.2 (note: http protocol has TCP port 80).

Port Mapping Guide¶

1) Go to the submenu item NAT via the menu item Firewall

Port Mapping

2) Now add a new NAT rule with Add

Port Mapping

3) Enter the data as in the example

Port Mapping

4) Afterwards the NAT rule appears in the Network Address Translation (NAT) Rules table as shown below

Port Mapping

The rule is now active. The corresponding services restart and the port mapping is fully set up.

For a working port mapping it is helpful to check the settings of the connected devices in advance. The following checklist is helpful (according to the example above):

Does the camera have the IP address 192.168.2.12?
Does it respond at “ping 192.168.2.12”?
Is the web interface of the camera accessible via http://192.168.2.12?
Is the Welotec router entered as the default gateway for the camera (192.168.2.1)?

SMS Functions¶

The TK800 can be reached by SMS from the outside and reacts to various commands sent by SMS. One has the possibility to query the status of the device, to start / stop the dial-up or to restart the device.

Status Request / Restart¶

1) Go via the menu item Network to the submenu item SMS

Status Request

2) Click the Enable checkbox to turn on the function

Status Request

3) Enter in the table SMS Access Control the phone numbers (Phone Number) (format 4917123456789, no 0049 or +49!), which are allowed to send SMS to the router. Enter “permit” as action.

If now an SMS with the content show is sent to the mobile phone number of the router, the router sends its current status as response

Status Request

If an SMS with the content reboot is sent to the router, it will reboot. You can also monitor this process in the log of the router

Status Request

Connecting or Disconnecting from the Internet¶

After successful configuration, you can also control the router’s Internet connection via SMS. However, this requires the router to be set to “Connect On Demand”!

1) Go to the submenu item cellular via the menu item network.

2) Now select the cellular tab
