If you don\'t need to take shell version: please moveitem.The price is more affordable

Product features:

1.5 way electrical isolation CAN, can be configured freely for a variety of modes, such as 1 into 4 out, 2 into 3 out, 3 into 2 out, 4 into 1 out.

2. wide voltage input (DC:6-36V)

CANHub function:

Increase the number of nodes in the CAN network
Changing the topology of CAN network cabling
Exponentially extend the communication distance of CAN networks
CAN network connecting different baud rates

Device parameter:

1.5 way independent isolation CAN (isolation voltage 2500V)

2., the device can be configured freely, select each route to other forwarding rules.

The baud rate of the 2.5 way CAN can be adaptive.

3., each road has 50 CAN data cache, instant high-speed, data is not lost!

4. forwarding delay, in the worst case, is 200us.

Configuration software screenshot:

As shown above, the data received on the CAN0 network is forwarded to the CAN4 network, and the data received on the CAN1 network is forwarded to the CAN4 network,

The data received on the CAN2 network is forwarded to the CAN4 network, and the data received on the CAN3 network is forwarded to the CAN4 network, and the data received on the CAN4 network is forwarded to the CAN0, CAN1, CAN2 and CAN3 networks.

 

Figure CAN0: forward received the data on the network to the CAN1, CAN2, CAN3, CAN4 on the network, forwarding received CAN1 data on the network to the CAN4 network, CAN2 network data forwarding received to the CAN4 network, CAN3 network data forwarding received to the CAN4 network, CAN4 network data forwarding received to CAN0, CAN1, CAN2, CAN3 network.

A lot of friends in the industrial field has to deal with CAN bus is not very stable, such as original 40 node in the network, but there are always a few nodes from time to time drop, etc., so how about wiring, design to circumvent the CAN bus is not stable, distance from the problem of short? The best CAN network wiring method is of course the total line, the overall linear network structure is clear, easy to maintain, at both ends, plus 120 ohmic resistance, the measured access node CAN reach up to 70, as follows:


However in the practical engineering, the scene is always more complex and changeable, makes the CAN network cabling as main line, CAN not be the actual situation is the main line, the combination of star, as follows

 

 

 

This connection will generally lead to the following questions:

 

1. The number of nodes in the access to the poor, even more than a dozen nodes can\'t normal communication;

 

2. Strong interference region and weak interference region together, makes the unstable expanded to the whole of CAN bus network;

 

3. The CAN bus communication distance sharply shorten, originally CAN run 500 meters in theory, but less than 100 meters;

 

4. CAN the choice of terminal resistance is complicated, CAN bus waveform distortion seriously;

 

5. From time to time with the node drops to communication;

 

6. All nodes of the baud rate must be consistent, otherwise can\'t normal communication

 

 

Solution is as follows:

 

 

Assume that the whole network is divided into three regions (A/B/C)

 

A/B/C is not directly connected to the wires, but CAN be connected using A CAN repeater (CANRelay) or CAN hub (CANHub), as shown in the figure:

Such A/B/C3 A network all separate into three separate networks, and can communicate between them, more importantly, they can use completely different between the three network baud rate, the number of nodes in the network can access also greatly improve (more than 3 times), three networks are also became the main line structure, communication distance has also been extended. Similarly, CANHub CAN be used to solve this problem, as shown (the fast thinking technology\'s CANHub - S5 CAN access up to five CAN networks) :

The two options can be selected as needed. CAN bus communication distance table (theoretical distance) :
