Bộ chuyển đổi (Bridge) 2 cổng CAN Bus cách ly ICP DAS I-7532-G CR
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.

Utility
-
Provide CAN bus User-Defined Baud Rate / CAN-ID Acceptance Filter / CAN-ID Mapping configuration
-
Provide saving the CAN acceptance filter data to file. The “*.dat” file format is compatible with configuration file of I-7565-H1/H2. The “*.xls” file is useful for CAN hardware interface of other companies to configure CAN-ID filter function of I-7532
-
Support ICP DAS CAN hardware interface including “RS232 to CAN”, “Ethernet to CAN”, “USB to CAN”, “CAN Card” series products for configuration
