1 Introduction
I-2533 is a local CAN bridge used to establish a connection between two
CAN bus system via fiber optic transmission medium. In order to solve the
problem between CAN and fiber transmission medium, I-2533 is specially
designed for converting the electrical CAN bus signal to fiber optic cables. Not
just like I-2533, I-2533 has three more important features.
First, the transmission distance limitation of the CAN bus system will not
reduced because of CAN baud rate. It means that the total network 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. Besides, I-2533 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 message filter. When users use the I-2533 on two CAN network
with different CAN baud rate, it may be useful to reduce the bus loading on the
network which has low baud rate.

F.G.
Frame Ground.
Sometimes, the CAN_GND voltage level of different CAN devices on a
CAN bus system are not equal. In this case, it could cause some problems and
derogate the system stability. There is one way to relieve this situation; users
can connect the CAN_GND of different CAN devices with each other to
balance the voltage level of CAN_GND.
Electronic circuits are always influenced by different levels of
Electro-Static Discharge (ESD), which become worse in a continental climate
area. F.G. provides a path for conducting the ESD to the earth ground.
Therefore, connecting the F.G correctly can enhance the capability of the ESD
protection and improve the module‟s reliability.
Wiring of CAN_GND and F.G. is not necessary; users can modify the
configuration of wiring according to real applications.
