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.

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.

3.3.5. CAN Merging Rule Configuration

This field is used to configure merging rules of the device. Merging rule is used to combine multiple CAN frames (Max. 8) to one CAN FD frame. It is useful for user to combine multiple CAN frames datas into one CAN FD frame. Each device maximum supports 32 merging rules.

The merging rule field is similar to mapping rule field. After setting the rules on “Merging Rule Configuration” frame, rules will be display ed on the fr ame list. The smaller the “No” number, the higher the process priority level.User can press the “Add” but ton to add a new rule or press the “Modify” button to modify the selected rule.

I-7532M-FD ( 2-port CAN/CAN FD Bridge ) User Manual (version 1.2.0) Page: 35

 The CAN F D frame will be sent out when receiving the latest “No” of CAN frame. All

the received CAN frames datas in the CAN list will be combined to the data field of the CAN FD frame.

 Each merging rule maximum support merging 8 CAN frames to to one CAN FD

frame, and the total data l ength of these CA N frames can not large than the CAN FD frame “DL” value.

 In the same merging rule, each CAN frames IDs are different to each other.  The “Stuff Byte” value will be stuffed into CAN FD frame data field when the sum of

all CAN frames data length is less than t h e CAN FD fra me “DL” value.

3.3.6. CAN Splitting Rule Configuration

This field is used to configure splitting rules of the device. Splitting rule is used to split one CAN FD frame to multipl e CAN f r a mes ( Ma x. 8 ). It is useful for user to split datas in one CAN FD frame to multiple CAN frames. Each device maximum supports 32 splitting rules.

The splitting rule field is similar to merging rule field. After setting the rules on “Splitting Rule Configuration” frame, rules will be display ed on the fr ame list. The smaller the “No” number , the higher the process priority level. User can press the “Add” button to add a new rule or press the “Modify” button to modify the selected rule.

3.3.6.1. Splitting Rule Examples

1. Split one CAN FD frame to four CAN frames.

When receiving the CAN FD frame (standard ID: 0x123, DL: 32, BRS enable) on port 1, t his frame will be splitted into four CAN frames (standard ID: 0x001, 0x002, 0x003, 0x004) with 8 bytes datas and sent out to port 2.
