Bridges, Gateways and Routers

Easy coupling of networks and devices using
filters and simple translation rules.


Ixxat bridges, gateways and routers enable interconnection of CAN and CAN FD networks using either CAN technology, Ethernet, WiFi or Bluetooth. Filter and mapping rules or C user code allows smart decoupling of segments. Using bridges and gateways the maximum expansion of a CAN (FD) network can be increased, tree and star topologies can be implemented and networks can be linked over large distances.

CANbridge NT 200/420

Configurable CAN-to-CAN Bridge/Router with CAN FD Support

The CANbridge NT is offered in two versions, as CANbridge NT 200 with 2 classic CAN channels and as CANbridge NT 420 with 4 CAN channels, where 2 channels can be switched between CAN and CAN FD. 
Both devices allow the easy coupling of CAN (CAN FD) networks, including networks with different bit rates or frame formats (11/29 bit identifier). The bridges/routers have a powerful microcontroller that can perform message filtering, ID translation and data multiplexing (e.g. required for CAN FD to CAN message conversion), at this even bursts at higher data rates can be processed without message loss.

How it works

Unlike a CAN Repeater, which only translates the electric signals, the CAN messages are received completely by the CANbridge NT and then sent to the other CAN or CAN FD network in line with existing filter, conversion, port mapping or multiplex rules (Store-Forward principle). With two CANbridge NT 420 it is possible to transmit messages between two Classic CAN networks via a CAN FD network (CAN tunnel).

Filtering and multiplexing
By using mapping tables the message reception/transmission is possible between all 4 channels. With the aid of filter and conversion rules, CAN or CAN FD messages can be filtered or modified. With these mechanism, the bus load can be reduced in the individual networks by only sending messages which are of interest to the other network. For SAE J1939 applications a special mapping table is provided, adapted to the specific parameters. The data multiplexing/demultiplexing functionality enables the mapping of e.g. CAN-FD data to several standard CAN messages and vice versa. 

Action Rules
In response to received messages, device or CAN bus status events, a variety of actions can be performed automatically, e.g. sending messages (CAN, CAN FD), changing device settings or switching device LEDs. Action rules are created through intuitive drop-down menus for events and actions within the Windows-based device configuration tool or by using LUA scripts.

Cyclic transmission
The cyclic transmission feature enables cyclic forwarding of messages. Both, messages and cycle times are defined within a central cyclic transmission table. 

Configuration

The configuration of the CANbridge NT and the firmware upload is done with an intuitive to operate Windows configuration tool via USB. With the tool, the configuration of filter, mapping, multiplexer or translation rules can be carried out very easily, without programming skills.
