I 7532 spec eng
Two-channel CAN Bus Isolated Bridge
I-7532
The 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 I-7531, I-7532 have three more important features. First one,
the transmission distance limitation of the CAN bus system on each side of I-7532 are independent,
which means the total network distance can be extended. Second one, when the CAN bus system on
one side of I-7532 happens some error (e.g. bit error), the system on other side can still work on
correctly. Last one, the baud of two channels on I-7532 can be different for highly flexibility.
