I-7530 RS-232/CAN Converter User’s Manual (Version 2.0, Sep/2007) ------------- 3
1. Introduction
CAN (Controller Area Network) is a serial bus control protocol
especially suited to structure intelligent industry devices networks and
build smart automatic control systems. By using I-7530, some
programmable RS-232 devices such as PC, I-8411/I-8431/I-8811/I-8831
embedded controllers, can be the master of a CAN network. Therefore,
they can control or monitor the CAN devices via the I-7530 module.
Moreover, we expand the functionalities of I-7530 for some special
application. In pair connection mode, I-7530 can be used to connect PC
with other RS-232 devices at the same time. The application architecture
may be as follows.
