I-7530A ~ NEW ~
RS-232/422/485 to CAN Converter |

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.

There are various communication interfaces among the CAN devices like PCI CAN board, Ethernet series and RS-232 series CAN module. According to different purpose of users¡¦ projects, the users maybe need to choice different CAN products. Because of this situation, the programmer should develop different communication program to handle different CAN device. For example, the user should develop ¡§Socket Client¡¨ to communicate with I-7540. When using I-7530, the users need ¡§UART¡¨ technique to communicate with it. Nowadays, ICP DAS develop the Virtual CAN technique. The Virtual CAN driver is the excellent tool for users. It transforms whole CAN devices into Virtual CAN port. And then it generates Virtual CAN port like ¡§VxCAN 1¡¨ or ¡§VxCAN 2¡¨. The users could send and receive CAN message by appointing the Virtual CAN port number. The users don't need to care about what kind of CAN device which is used.
