Intelligent RS-232 to CAN converter. I-7530T is phased out and replaced by I-7530.


Intelligent RS-232 to CAN converter. I-7530T is phased out and replaced by I-7530.

    Item Not Available  


The I-7530T has officially been phased out and will no longer be available. It has now been replaced by I-7530.

CAN (Controller Area Network) is a serial bus system especially suited to structure intelligent industry devices networks and build smart automatic control systems. The PC can be the CAN host, monitor or HMI to access/control the CAN device through the CAN network by the I-7530T Converter. The programmable RS-232 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-7530/I-7530T/I-7530FT modules. In order to use the CAN network with traditional RS-232 devices, we provide a way to achieve this purpose. The I-7530T is designed to unleash the power of CAN bus via RS-232 communication method. It accurately converts messages between CAN and RS-232 networks. This module let you to communicate with CAN devices easily from any PC or devices with RS-232 interface.

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