1. Introduction
I-7532M-FD is a local CAN/CAN FD (CAN with Flexible Data-Rate) bridge used to
establish a connection between two CAN/CAN FD networks. It can increase the bus
loading capacity, extend communication distance, connect CAN/CAN FD networks with
different baud rate and support messages transform between CAN and CAN FD
networks.
I-7532M-FD supports messages transform from CAN to CAN, CAN to CAN FD,
CAN FD to CAN and CAN FD to CAN FD. Besides, It also supports frame mapping rule,
merging rule(combine multiple CAN messages to one CAN FD message) and splitting
rule (split one CAN FD message to multiple CAN messages) for some specific
messages transformation. Users can freedom to use these rules for their application.
After connecting USB port with PC, user can use I-7532-FD Utility tool to configure
module’s baud rate and rules. Then user can simple and easy to use the module.

2.2. Pin Assignment
The pin assignments of CAN port and power connector of I-7532M-FD is shown in
the following tables.
Table 2-2-1 Pin Assignment
Port Schematic diagram Pin Description
CAN
1. CAN_GND CAN ground of CAN port
2. CAN_H CAN_High bus line of CAN port.
3. CAN_L CAN_Low bus line of CAN port.
Power
1. +Vs Voltage Source Input.
+10VDC ~ +30VDC.
2. GND Power Ground.
3. 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.

2.4. 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 2-4-1 CAN bus network topology
Each I-7532M-FD includes two 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.
Figure 2-4-2 Location of Terminal resistor DIP Switch
The following DIP switch statuses present the condition if the terminal resistor is
active (default) or inactive.
