Repeaters

for CAN, CAN FD and
CAN-based higher layer protocols



Ixxat repeaters are used to establish a physical coupling of two or more segments of a CAN or CAN FD bus system. They can be used to implement tree or star topologies as well as for long drop lines. In addition, network segments can be electrically decoupled using a galvanically isolated repeater. 


CAN Repeaters
HMS_web-icon_High performance

Increase reliability

CAN and CAN FD repeaters increase your system reliability with almost no influence on the real-time behavior.

HMS_web-icon_diagnostic

For harsh environments

Ixxat repeaters decouple CAN or CAN FD segments galvanically up to 4 kV and are also available as variants with fiber optics.

Save costs

Easier wiring and reduction of cables reduces the cost of your system.

CAN-CR200

Modular ISO 11898-2 CAN repeater
with backbone bus

The CAN-CR200 is used for the galvanic isolation of two segments of a CAN network and for creating star or tree topologies. Several CAN-CR200 can be connected to a CAN-hub via the integrated backbone bus. One special feature of the Repeater is the automatic recognition and separation of a defective segment from the rest of the network so that the remaining network can continue working. After elimination of the defect, the segment is switched into the network again.

The galvanic isolation isolates the CAN segments from each other as well as from the power supply.

The lines coupled by the repeater are independent electric segments that can be optimally terminated in terms of signals. In this way topologies can be implemented that are not possible with a pure line of the bus due to electrical reflections. According to the transceiver output capacities, the division of a CAN / CAN FD system into several subsystems, connected via CAN / CAN FD repeaters, increases the maximum number of bus nodes. Using repeaters does not influence the real-time behavior of a system because in terms of transmission behavior it corresponds to a network that consists only of lines. In terms of signals, the repeater corresponds to a line with relevant delay time. Therefore, it cannot be used to extend a CAN / CAN FD system. However, using repeaters allows to increase the system dimensions indirectly, as shown in the sample.
