Introduction
ICP DAS has provided a lot of UART/CAN product solutions which are widely recommended in the market. These UART/CAN converters can help users to implement the communication between RS-232 and CAN network. In order to cater for costing requirement, we provide a new solution of RS-232/CAN converter-tM-7530. The tM-7530 is a tiny RS-232/CAN to fit narrower environment as a result of its small size. It has isolation on power side and on CAN bus side and its performance is faster than other RS-232/CAN module. The function of tM-7530 can full compatibly with I-7530 and I-7530T. Besides, it provides new function such as listen only. User can use this function to listen CAN bus messages and error detection. According to above features, tM-7530 is an economical and practical RS-232/CAN converter solution.
Moreover, we expand the functionalities of tM-7530 for some special application. In pair connection mode, tM-7530 can be used to connect PC with other RS-232 devices at the same time. The application architecture may be as follows.
Applications
- Control System
- Building Automation
- Factory Automation
- Distributed data acquisition

The tM-7530 uses VxCAN Utility to configure and test. VxCAN is a technique of ICP DAS and we call it "Virtual CAN". It is used to integrate all of ICP DAS CAN converter modules. Via this technique and its Windows platform API, users can develop utility tool by themselves to fit their application. The VxCAN Utility is also developed by using this method. Thus, we will integrate all CAN converter utility via VxCAN Utility in the future. About more VxCAN information, please refer to VxCAN Utility website.
