CAN-Gateway Configurator V6 for CAN@net NT and CANbridge NT

2.2. Operational Modes CAN@net NT

2.2.1. ASCII Gateway Mode

In the Gateway mode, the CAN@net NT is directly hooked to the local intranet or internet (firewall needed).
This allows a TCP/UDP 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 network can exchange commands and CAN messages using the ASCII
protocol. The CAN@net NT relays the commands and messages to the CAN bus and vice versa..
Figure 1. Gateway Mode
For information about the communication in Gateway mode and commands that are used to exchange CAN
messages see Software Design Guide CAN@net NT 100/200/420 Generic Protocol for Gateway Mode on
CAN@net NT support pages on www.ixxat.com/support-bridges-gateways.

2.2.2. Local CAN Bridge Mode

A single device can be used as Local CAN Bridge, which allows to map individual messages from and to each CAN
port of the device. NT 420 devices additionally are capable of CAN FD.
The following settings and features are possible:
• Use of Lua ADK
• Syslog
• MQTT
• Remote access
• Expert mode
• Communication Error Severity
• Action Rules
• Mapping table
• J1939 Mapping
• CAN FD/CAN Demultiplexing (only CAN@net NT 420)
• CAN/CAN FD Multiplexing (only CAN@net NT 420)
• Cyclic transmission

2.2.3. CAN-Ethernet-CAN Bridge Mode

IMPORTANT
Exclusively one master device is allowed in the Bridge mode.
The CAN-Ethernet-CAN Bridge mode allows to connect CAN systems over an Ethernet TCP/IP network, for
example the local intranet or the internet (firewall needed). Minimum two devices are required for a CAN-
Ethernet-CAN Bridge. One has to be configured as master and one as slave. With the NT 100 and NT 200 two
devices can be combined to a CAN-Ethernet-CAN bridge. With the NT 420 up to four devices can be combined.
The CAN@net NT 420 additionally is capable of CAN FD.
