CAN Isolation Gateway Bridge Switch Series
The CAN isolation bridge switch series is equipped with 2 or 4 electrical isolated CAN bus interfaces. It can achieve the relay function in the CAN-bus network, and save to forward data among the CAN networks with different speed. Main applications include:
(1)Increase nodes and lengthen communication distance.
(2) Realize the inter-connection of various CAN networks with different Baud rate.
(3)This series product has powerful ID filtering conversion and data conversion functions.
(4) This series product has powerful anti-interference capability.

CANBridge strongly recommended by SIEMENS Security System
Configuration Software
1.When configuring the CANBridge, users only need to correctly set Baud rate for two channels. The filtering setting should only be used as required. The following figure shows that a certain 100kbps bus is lengthened to 100m from 50m and only the messages with0x001-0x005 ID are allowed to pass.
2.CANBridge+ has frame mapping function, and maximum 64 frames can be provided for a single channel. In some special occasions, the received IDs should be converted into other IDs, or the data part of frame needs to be converted. The frame ID and data can be conveniently changed by using the frame mapping function.
3.When configuring CANHub-AS4, users only need to correctly set the Baud rate and routing for four channels. The filtering setting should only be used as required. The following figure shows the example that the host is connected to CAN1 and the messages are forwarded to CAN2, CAN3 and CAN4 from CAN1. Users can observed that messages of CAN2, CAN3 and CAN4 can only be forwarded to CAN1 instead of other channels. In this way, the invalid data forwarded can be greatly reduced, thus improving the bus utilization rate.
4.The configuration software can monitor CAN operation status, and obtain bus errors in real time to help the field operators to determine fault causes.
