1. Introduction
The I-2533T-FD is a local CAN/CAN FD (CAN with Flexible Data-Rate) bridge used
to establish a connection between two CAN bus system via multi-mode fiber optic
transmission medium. In order to solve the problem between CAN/CAN FD and fiber
transmission medium, the I-2533T-FD is specially designed for converting the electrical
CAN/CAN FD bus signal to fiber optic cables. Besides, I-2533T-FD has three more
important features.
First, the transmission distance limitation of the CAN bus system will not affected
due to the different CAN/CAN FD baud rate. It means that the total CAN/CAN FD bus
working distance can be extended. Second, the bus error on one CAN/CAN FD network
will not affect the operation of another CAN/CAN FD network. Finally, the two CAN/CAN
FD network can communication with each other by using different CAN/CAN FD baud
rate for highly flexibility.
The I-2533T-FD is designed for multi-mode fiber, and allow to extern CAN/CAN FD
bus to maximum 2 km. Besides, I-2533T-FD provides the group function, which is the
basic message router. Users can decide the CAN/CAN FD message flows between
several CAN/CAN FD bus systems. I-2533T-FD 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/CAN FD message filter. When users use the
I-2533T-FD on two CAN/CAN FD network with different CAN baud rate, it may be useful
to reduce the bus loading of the network which has low baud rate.

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.

2.6. Terminal Resistor Setup
In order to minimize the reflection effects on the CAN bus line, the CAN bus line has
to be terminated at both ends by two terminal resistors as in the following figure.
According to the ISO 11898-2 spec, each terminal resistor is 120Ω (or between
108Ω~132Ω). The bus topology and the positions of these terminal resistors are shown
as following figure.
Figure 2-6-1 CAN bus network topology
Each I-2533T-FD includes one build-in 120Ω terminal resistor, users can decider to
enabl it or not. The DIP switch for terminal resistor is on the upper of the CAN
connector.

The following DIP switch statuses present the condition if the terminal resistor is
active (default) or inactive.

Generally, if your application is as follows, we recommend you to enable the
terminal resistor.

2.7. Module Group ID
The CAN port with the same “Group ID” setting can communicate with each other
via fiber optics. This setting is used for I-2533T-FD to communicate with the others
modules on star topology application.
Users can decide the value from 0 to 3 via pin 8 ~ 9 on 10-pin dip switch. The dip
switch for “Group ID” is over the power connector.

For example, there are three CAN networks, NetworkA, Network B and Network C, and
each of them uses one I-2533T-FD. The Group IDs of the I-2533T-FDs are 1, 2, and 3
respectively. The Network A can exchange the data with Network C because the Group
IDs of the I-2533T-FDs are in the same group (the second rule in the above table). The
Network B can exchange the data with Network C, which follows the third rule in the
above table. The Network A can’t connect with the Network B because these two
I-2533T-FDs are not in the same group.
