CAN (Controller Area Network) is a serial bus system especially suited to structure intelligent industry devices networks and build smart automatic control systems. The following figure shows the application architecture for I-7530A modules. The PC can be the CAN host, monitor or HMI to access/control the CAN device through the CAN network by the I-7530A Converter.

The programmable RS-232/485/422 device (For example: I-8411/I-8431/I-8811/I-8831/W-8031/W-8331/W-8731 embedded controller) can use the serial port to connect to the CAN network via the I-7530A module. In order to use the CAN network with traditional RS-232/485/422 devices, we provide a way to achieve this purpose. The I-7530A is designed to unleash the power of CAN bus via RS-232/485/422 communication method. It accurately converts messages between CAN and RS-232/485/422 networks. This module let you to communicate with CAN devices easily from any PC or devices with RS-232/485/422 interface.

Moreover, we expand the functionalities of I-7530A for some special application. In pair connection mode, I-7530A can be used to connect PC with other RS-232/485/422 devices at the same time. The application architecture may be as follows.

3000V isolation on CAN side
The CAN port of I-7530A is an isolated with 3000V isolation. This isolation can protect the local RS-232/485/422 devices from the damage signal coming from CAN network.

Watchdog inside
The I-7530A Watchdog is a hardware reset circuit to monitor the I-7530A’s operation status. When working in harsh or noisy environment, the I-7530A may be down by the external signal. The circuit may let the I-7530A to work continuously and never halt.

Power and Error indicator display
There are two indicators on the I-7530A.The power indicator can help user to check whether the I-7530A is standby or transmitting/receiving messages. The Error indicator will be turned on when some errors occur on the I-7530A.
