For information about the communication in Gateway mode and commands that are used to
exchange CAN messages see Software Design Guide CAN@net NT 200/420 Generic Protocol for
Gateway Mode on www.ixxat.com.
4.2.2 Bridge Modes
With the CAN@net NT the 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 must be configured as master and one as slave.
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.
Possible Bridge Modes with CAN@net NT 200:
• Local CAN Bridge
• CAN-Ethernet-CAN Bridge with 2 devices
Possible Bridge Modes with CAN@net NT 420:
• Local CAN Bridge
• CAN-Ethernet-CAN Bridge with 2 devices
• CAN-Ethernet-CAN Bridge with 3 devices
• CAN-Ethernet-CAN Bridge with 4 devices
