1. Introduction I-7532RM-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.
2.2. Pin Assignment The pin assignments of CAN port and power connector of I-7532RM-FD is shown in the following tables. Table 2-2-1 Pin Assignment Port Schematic diagram Description 1. CAN_GND CAN ground of CAN port 2. CAN_H CAN_High bus line of CAN port.
2.3. LED Indicator There are 4 LEDs on the I-7532RM-FD. One for power indication, one for USB indication and two for CAN bus indication. The LED assignment and description are shown as follows. Table 2-3-1 LED Description LED Name Status...
2.4. Rotary Switch There are 4 rotary switches on the I-7532RM-FD for configuring CAN1/2 arbitration and data phase baud rate. The descriptions are as follows. CAN1 A_BR/D_BR CAN1 Arbitration/Data phase baud rate CAN2 A_BR/D_BR CAN2 Arbitration/Data phase baud rate...
108Ω~132Ω). The bus topology and the positions of these terminal resistors are shown as following figure. Figure 2-5-1 CAN bus network topology Each I-7532RM-FD includes two build-in 120Ω terminal resistor, users can decide to enable it or not. The DIP switch for terminal resistor is on the upper of the CAN connector.
2.7. CAN Bus Driving Capability Before introducing the driving capability of the I-7532RM-FD, some characteristics of copper cable must be assumed. The recommended AC parameters are 120Ω impedance and 5ns/m line delay, and the DC parameters are shown in the table below.
3. Software Utility When users want to use user-defined CAN/CAN FD baud rate, CAN/CAN FD message filter and CAN mapping, merging, splitting rule function on the I-7532RM-FD, the I-7532-FD Utility tool may be needed. NOTE: I-7532M-FD & I-7532RM-FD use the same “I-7532-FD Utility” tool.
Utility and the I-7532RM-FD. Here is the example for the I-7532RM-FD configuration. Step 1: Connect the PC available USB port with the USB port of the I-7532RM-FD by using a Type C USB cable. Step 2: Power On the module and execute the I-7532-FD Utility tool.
CAN ID and set acceptance standard/extended CAN ID. It uses a whitelist filtering method and supports 128 groups of standard IDs and 64 groups of extended IDs per port. I-7532RM-FD ( 2-port CAN/CAN FD Bridge ) User Manual (version 1.0.0) Page: 20...
