Installation guide

Typical use

With routers of the TK500 series you can connect devices with Ethernet, WLAN or RS-232/485 via GPRS/HSUPA/ UMTS/LTE to the Internet. To ensure security and uninterrupted access, the TK500 series supports VPN connections, enabling remote access and secure data transmission over the Internet.

Antenna installation

After installing the TK500, connect the antenna and screw the antenna tight. Place the antenna where a good signal strength is achieved.

note

Note

Position and angle can affect signal strength.

Power supply

Connect the power supply included in the scope of delivery to the device and check whether the LED display for “Power” lights up. Contact Welotec technical support if no indicator lights up. You can configure the TK500 when the power indicator is flashing.

Connecting

Connect the TK500 to the PC:

  1. Connect the Ethernet cable of the TK500 to the PC.

  2. Then one LED indicator of the RJ45 interface lights up green and the other indicators flash.

Connecting the TK router device to the PC for the first time

The TK500 router can assign IP addresses for the PC automatically. Set up the PC so that IP addresses are retrieved automatically via DHCP. (Basis is the Windows operating system):

  1. Open the Control Panel, double-click the “Network and Sharing Center” icon to open the “Network and Sharing Center” screen.

  2. Click “LAN Connection” and open the screen with the “Status of LAN Connection”:

status_LAN

  1. Click “Properties” and open the LAN connection properties screen:

config_LAN

  1. Select “Internet Protocol Version 4 (TCP/IPv4)”, click the “Properties” button, and check if your PC can obtain IP and DNS address automatically. (You can also set up the PC in the subnet: 192.168.2.0/24, e.g. IP: 192.168.2.10, netmask: 255.255.255.0 Default gateway: 192.168.2.1)

By clicking “OK”, the TK router assigns an IP address to the PC: 192.168.2.X, as well as the gateway: 192.168.2.1 (the default address of the TK500).

properties_LAN

After configuring the TCP/IP protocols, you can use the ping command to check whether the connection between the PC and the router is established without errors. The following is an example of running the ping command under Windows 7:

Windows key+R -> Enter “cmd” -> press Enter -> Enter “Ping 192.168.2.1” -> press Enter With this display:

bildneun

The connection between the PC and the router has been established correctly.

The following example contains errors:

image11

The connection is not working properly and you should go through the instructions again and check your settings.

Configuring the TK500 (Optional)

After you have performed the steps described in the previous chapter, you can configure the router:

  1. Open any Internet browser (e.g. Google Chrome) and enter the default IP address of the router: http://192.168.2.1. The following login page pops up:

image12

Enter the user name (default: adm) and password (default: 123456), and then click “Login” to open the configuration screen.

  1. Change the IP configuration:

If you want to set your own IP, follow the instructions below:

image13

  1. Click Network >VLAN.

  2. To add a VLAN ID, click “Add”.

changeIP1

For example, change the IP address to 192.168.1.254 and select the LAN ports to be assigned to this IP address.

changeIP2

  1. Click “Apply” and the following screen will be displayed:

image15

The IP address of the TK500 has been changed. In order for you to access the configuration page again the PC must be set up in the same subnet, for example: 192.168.1.10/24 - Then enter the changed IP address (192.168.1.254) in your browser.

Connecting the TK router to the Internet

Perform the following configuration steps to establish a connection between the TK500 and the Internet.

Click Network > Cellular, and enable the function by Enable:

image16

Check the entries and select a preset network provider under SIM1 Network Provider, or add a self-created profile of a provider:

You can obtain the APN, dial-in number, user name and password from your local network provider. Check with them for the details.

Via Show Advanced Options you can make further settings, such as the PIN code if it is set on the SIM card.

image17

If you have set the correct configuration, the TK500 can now connect to the Internet. Open an Internet browser, type “www.welotec.com” and the Welotec website will open.

Reset to factory settings

Hardware method
