I-7532 is a CAN bridge used to establish a connection between two CAN bus systems in a CAN network and more functions are equipped than I-7531 (CAN Repeater). Three powerful features are provided by I-7532. First, the transmission distance limitation of the CAN bus system on each side of I-7532 are independent, which means the total CAN network distance can be extended. Second, when some errors (e.g. bit error) happened on one side of I-7532 of the CAN bus system; the other side can still work correctly. Last one, the baud rate and filter setting of these two CAN channels on I-7532 can be different for highly flexibility and efficiency.
