I-2533CS series
|
The I-2533CS series (I-2533CS, I-2533CS-60, I-2533CS-A and I-2533CS-B) is a local CAN bridge used to establish a connection between two CAN bus system via single mode fiber optic transmission medium. In order to solve the problem between CAN and fiber transmission medium, the I-2533CS series is specially designed for converting the electrical CAN bus signal to fiber optic cables. Besides, the I-2533CS-A/B supports Wavelength Division Multiplexing (WDM) technology so that only a single fiber cable is needed for transmitting bi-directional CAN data. As the I-2533CS-A and I-2533CS-B must be paired because of hardware limitations, this means that the cost of deploying fiber cable can be effectively reduced.
I-2533CS series has three more important features. First, the transmission distance limitation of the CAN bus system will not affected due to the different CAN baud rate. It means that the total CAN bus working distance can be extended. Second, the bus error on one CAN network will not affect the operation of another CAN network. Finally, the two CAN network can communication with each other by using different CAN baud rate for highly flexibility.

Description
Applications
The mainly difference between I-2533 and I-2533CS series are fiber connectors and transmission distance. The I-2533CS series is designed for single mode fiber, and allow to extern CAN bus to maximum 30 km. Besides, I-2533CS provides the group function, which is the basic message router. Users can decide the CAN message flows between several CAN bus systems. I-2533CS series also provides the utility tool for user-defined baud rate and filter configuration. By using this tool, it is allowed to have user-defined baud rate and CAN message filter. When users use the I-2533CS series on two CAN network with different CAN baud rate, it may be useful to reduce the bus loading of the network which has low baud rate.

Note1:
The I-2533CS-A and I-2533CS-B is a couple. Users must use pair in the applications. Due to this characteristic, the Group ID of the I-2533CS-A and I-2533CS-B is not used..
Note2:
The propagation delay depends on the CAN Bus baud rate and the CAN message format. This value has been tested using a CAN baud rate of 1 Mbps, the CAN ID 0x12345678 and 8 bytes of data with a value of 0xFF.
