Hint
If you select a diamond grinding disc, the dresser remains at the side of the grinding
chamber because it is not used.
Hint
Struers recommends that you dress a new stone a couple of times before using it for
grinding. This will ensure that it is plane and ready for use.
4.14 Network connection
Xmatic cannot use wireless networks (Wi-Fi/Bluetooth).
The machine is equipped with an RJ45 connector which should only be used for remote service.
Inside the machine, the RJ45 connector is connected to a Teltonika RUTX08 router (Linux operating
system) which manages the firewall and a VPN client.
All ingoing connections through LAN on any ports will be rejected by the firewall.
The following ports are recommended to keep open for outgoing connections:
Port Type Description
53 TCP/UDP DNS lookup
123 TCP/UDP NTP (time server)
15009 TCP Teltonika RMS
15010 TCP Teltonika RMS
20022 TCP Remote SSH through RMS
20100 TCP Remote SFTP through RMS
30000 - 39999 UDP Teltonika VPN server (single
random port is used)
Remote service through VPN
To get remote service through a VPN server, the machine must have access to the Internet.
The router is pre-configured, and a certificate is pre-installed by Struers. With an Internet connection,
the machine has access to the Teltonika VPN server (OpenVPN-based).
Remote service should be used for software updates and troubleshooting.
Struers can provide you with a MAC address for the specific router installed in the machine.
The encrypted VPN connection can give the technician from Struers Service remote access to the
user interface and the database on the machine.
