Appendix B: Connection of the Data Logger to Internet

Danger

It is strongly recommended that connection of the data logger to Internet is carried out under supervision of the system administrator of the local network or a representative of the internet provider.

Requirements for Internet Connection

For connection of the data logger to Internet, use the following recommendations:

1. Obtain a dedicated line with a static IP-address from internet provider (further referred to as “provider”)
2. Inform the provider about the MAC-address of the data logger

Caution

The direct connection of the data logger to the provider’s cable is not recommended.

Router Configuration

At connection of the data logger via a router (routing gateway):

1. Connect the provider’s cable to the router’s WAN slot (usually with a color indication without number, depending on the router manufacturer the indication can differ – see the router documentation)

2. Use the Ethernet cable supplied with the data logger for connection of the data logger to the router

3. Guided by the router manual, adjust the router for connection to Internet network according to the provider’s recommendations

4. In the router settings, switch on the port forwarding of incoming packages to the IP-Address of the data logger (factory setting – 192.168.0.2)

Accessing the Data Logger Remotely

At addressing the data logger in Internet network, you should use the IP-Address obtained from the provider (your static public IP address).

Common ports used by RPM-416:

• HTTP (Web-interface): Port 80 (default)
• Modbus TCP: Port 502 (default)
• FTP: Port 21 (default)

Configure your router to forward these ports to the data logger’s internal IP address (192.168.0.2).

Security Considerations

Danger

The integrated in RPM-416 security access features are not intended against malicious network attacks (especially the attacks whose purpose is blocking the access to the device).

You should secure the connection of the data logger to Internet network by standard means of protection (for example, Firewall).

Security Recommendations

1. Change default passwords – Update the default “admin” password to a strong, unique password
2. Use a firewall – Configure your router’s firewall to only allow connections from known IP addresses
3. VPN connection – Consider using a VPN for remote access instead of direct internet exposure
4. Regular monitoring – Monitor access logs for suspicious activity
5. Keep firmware updated – Install firmware updates when available
