1. Introduction
The I-7532 is a CAN bus bridge that can be used to integrate two CAN networks even
they implement different CAN baud rate. Compared with the I-7531, the I-7532 offers
more than 3 useful features. First, the transmission distance limitation of the CAN bus
system on each side of the I-7532 is independent, which means the total CAN network
distance can be extended. Second, when some errors (e.g. bit error) happened on one
CAN port of the I-7532, the other CAN port of the I-7532 will not be affected and can still
work correctly. Last, the baud rate and CAN message filter configuration of these two
CAN ports on the I-7532 is able to be tuned following users' applications. These
features mean that users can design their applications more flexible and efficient.

4. CANBaud Rotary Switch
Users can use the “CANBaud Rotary Switch” to change the CAN1 and CAN2 baud of I-
7532 and it supports 15 kinds of baud shown on Table 2-3. After changing the rotary
switch value, users need to reset I-7532 to take the setting effect. If the “CANBaud
Rotary Switch” is set to be „0‟, then I-7532 will go into module configuration mode and
others of “CANBaud Rotary Switch” will go into communication mode.
