The I-7532 CAN Bridge Quick Start User Guide This user guide describes how to implement the I-7532 module into users’ applications in a quick and easy way. Therefore, it only provides the basic concepts. If users want to know more detail information about the I-7532, please refer to the user manual in the product CD or visit our website as follow: http://www.icpdas.com/products/Remote_IO/can_bus/i-7532.htm 1.

Introduction I-7532 is a local CAN bridge used to establish a connection between two CAN bus system in a CAN network. The I-7532 stands by itself connecting adjacent wiring segments together as in the case of a CAN repeater (I-7531). Not just like a CAN repeater, I-7532 has more powerful features (Extend Network Distance and Connect two networks with different baud rate).

Terminator Resistor Setting The I-7532 module includes two build-in 120Ω terminal resistors, users can decide to enable those two terminator resistors or not. The JP4 of I-7532 is used to adjust terminal resistor on CAN Channel 1, and the JP3 of I-7532 is used to adjust terminal resistor on CAN Channel 2. Before adjusting JP3 or JP4 of I-7532, users need to open the cover of I-7532 first. Those locations of JP3 and JP4 are shown as follows: JP4 JP3 The following connection statuses present the condition if the terminal resistor is enabled (default) or disabled.
