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 al so supports frame m apping 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 m odule.

 Compatible with the ISO 11898-2 standard.  Compatible with CAN specification 2.0 A/B and FD.  CAN FD support for ISO and Non-ISO (Bosch) standards switchable.  CAN FD bit rates for data field from 100 kbps to 10000 kbps  CAN bit rates from 10 kbps to 1000 kbps.  Support CAN Bus message filter configuration. White-list filtering method and

each port supports 128 groups of standard IDs and 64 groups of extended IDs.

 Support CAN/CAN FD frame forwarding rules, including basic forwarding rule,

mapping rule, merging rule and splitting rule. W hen receiving a frame on one CAN port, this frame is processed via these rules and then send out to another port. The process priority level of these rules are “merging rule” = “splitting rule” > “mapping rule” > “basic forwarding rule”.

 Support CAN network status analysis via Utility tool.  Messaging traffic of each port up to 10,000 fps.

 The baud rate of each port can be different for highly flexibility.  Built-in switchable 120 ohm terminal resistor for CAN network.

2.2. Pin Assignment

The pin assignments of CAN port and power connector of I-7532M-FD is shown in

the following tables.

2. GND Power Ground.

3. F.G. Frame Ground.

DC ~ +30VDC.

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 bu s line, the CAN bus lin e 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.
