Description
YN4561I CP2102 Converter USB/485/422/232/TTL Serial Port Module USB to RS485 Isolated Converter USB to Uart Adapter
Product Description
In embedded applications, the serial port is a widely used communication peripheral, but embedded engineers are inevitably troubled by the various standards and voltages of the serial port. Due to historical reasons, TTL level interfaces, RS232 level interfaces, and RS485 level interfaces have been formed. Different interfaces have their own characteristics, and the interface preferred by the device is also different.
Feature
· It can switch between USB, RS-232, RS-485 / 422, and TLL levels without the need for jumper dial switch settings. · Provide 1KV isolation between the four terminals to achieve safe isolation conversion. · Plug and play This product is compatible with USB2.0 standard and supports almost all operating systems. Just connect to your computer, install the driver and use it immediately. Data indicator for each data input · Automatic RS-485 data flow control · No external power required, fully powered by USB port
