YourCee USB-TTL/RS232/RS485/CAN Serial Communication Module
Data transfer is the process of converting data from one representation to another. A comprehensive software upgrade inevitably leads to a complete database upgrade. Each software has its own structure and data storage format for the underlying database, which can differ from one another. As a result, data conversion becomes necessary.
The device offers a diverse array of functionalities, including data caching, pass-through mode, and analog CAN capability. It supports data transfer rates ranging from 3 Kbps to 1 Mbps, allowing configuration within a specified range. Additionally, it is equipped with 14 sets of shielding filters to minimize signal interference. The device provides five distinct modes for user selection concerning frame filtering. In terms of connectivity, it can be linked via rows of pins. Furthermore, it offers a serial baud rate range extending from 1200 to 921600 bps, with a default setting of 9600 bps. This converter is specifically designed to facilitate the connection of USB devices to standard CAN bus systems.
