2.3 Block Diagram
The I-7530/I-7530T and tM-7530 provide CAN and RS-232
communication interfaces. The isolator is on the CAN side. The connector
of the CAN port to the I-7530/I-7530T and tM-7530 are the D-Sub 9-pin
male connector and the spring type connector respectively.

The hardware profile of the I-7530-FT is the same as the I-7530/I-
7530T. The main difference between I-7530-FT and I-7530/I-7530T is
followed CAN specification. The I-7530-FT is ISO 11898-3 device, which
is also called low speed fault tolerance (LSFT) CAN device. There is no
isolator on the I-7530-FT.

The I-7530A provides four communication interfaces in one module.
They are CAN, RS-232, RS-485 and RS-422 interfaces. Because the RS-
232, RS-485 and RS-422 are the same UART port, users can
’t use them
at the same time. The I-7530A also has isolator on the CAN side.
