Step 1: To power on and connect your gateway into your network switch via LAN cable.
- The network switch MUST be able to access Internet.
Step 2: To download Advanced IP Scanner and Putty to your laptop/PC.
- Download links are in this guide.
Step 3: To obtain the IP of your gateway from Advanced IP Scanner.
- Your laptop with Advanced IP Scanner MUST be in the same network with the gateway.
- If the IP of your gateway is not found, then you may need to reset your gateway to factory defaults.
Step 4: To access the Web interface of your gateway
- URL: http://
- Username: admin
- Default password: pwd4admin
Step 5: [Important] In the Web Interface, to make sure the gateway use the required frequency plan (EU868, US915, AS923…)
- By default, your gateway should be already set to the correct frequency plan (US915, EU868, AS923…) by the manufacturer.
- Else, you may need to verify and configure the frequency plan to the desired plan here.
Step 6: To use Putty to SSH into your gateway
- SSH to your gateway’s IP
- Username: root
- Default password: pdmk-$serialno (Last 6 digits of board ID). For example: pdmk-010001

Step 7: In Putty, to get your gateway EUI
- grep EUI /tmp/board_info.json
- Example output: “EUI64”: “7076FFxxxx03028B”. Then you keep 7076FFxxxx03028B as Gateway EUI for later use.
Step 8: In Putty, to enable Kerlink CPF
- klk_apps_config –activate-cpf
Step 9: In Putty, to configure Kerlink CPF
- vim /etc/lorafwd.toml
under the [ gwmp ] section:
node = “lorawanserver.easylorawan.com”
service.uplink =
service.downlink = - The uplink and downlink port are 5700 for EU868. For other frequency plans, you can check the ports here.
Step 10: In Putty, to restart your gateway
- monit restart lorafwd
- Or you can unplug and plug back the gateway.

- You can continue with the Quickstart guides here
Done.

- For newwer KerOS, you may check here
Step 1: Check the frequency setting in /etc/lorad/lorad.json
- SSH to the Kerlink
- cat /etc/lorad/lorad.json
This is a sample lorad.json for EU868.

Step 2:Â To backup the lorad.json
- cp /etc/lorad/lorad.json /etc/lorad/lorad.json.backup
Step 3: To edit /etc/lorad/lorad.json to fit your region
