4 Product Description
The CAN@net NT hardware provides connectivity to Ethernet and CAN networks with various
operational modes. The CAN@net NT 420 additionally is capable of CAN FD. The application
firmware provides functions to access a CAN bus from virtually every Ethernet TCP/IP host. The
CAN@net NT provides message filtering, based on CAN identifiers, for Bridge and Gateway mode
in the direction from CAN system to TCP/IP network. In the Gateway mode the filter can be
configured by ASCII commands. In the Bridge mode the configuration tool is used to configure
the filter. With the VCI driver the CAN@net NT can be used as a PC interface.
4.1 Features
• CAN@net NT 200: 2 x CAN connections, ISO 11898-2 (terminal adapters)
• CAN@net NT 420: 4 x CAN connections, ISO 11898-2 (terminal adapters),
via the CAN-Gateway Configurator two connections can be switched between Classic CAN
and CAN FD
• 1 x RJ45 Ethernet port, 10/100 Mbit/s
• 1 x mini USB 2.0 port, high-speed
• configuration via USB or Ethernet
• With the CAN-Gateway Configurator a configuration can be created, modified, written to
and read from the target device via USB or Ethernet connection.
• platform independent due to ASCII protocol
• Classic CAN/ CAN FD ID filtering
• Classic CAN to CAN FD mapping and CAN FD to Classic CAN mapping (with NT 420)
• cyclic transmission of CAN messages
• MQTT and syslog functionality
• command line program CANGWfile (available for Windows and Linux)
• action rules via if-this-action-then-that-event functionality
4.2 Operational Modes
4.2.1 ASCII Gateway Mode
In the Gateway mode, the CAN@net NT is hooked to the local intranet or internet (firewall
needed). This allows a TCP/IP host within the reach of this intranet or internet to connect to the
CAN@net NT and gain control of the CAN system. The Ethernet TCP/IP host can exchange
commands and CAN messages using the ASCII protocol. The server relays the commands and
messages to the CAN bus and vice versa.
