Description

U-485 is the USB to RS485 converter. The power supply of the product is from the USB port, and no need external power. Use the unique zero-delay automatic sending and receiving conversion technology and baud rate adaptive technology. Plug-and-play, suit for all software, and have the transceiver control. And it's in the high resistance state when not sending data.,support multi-point communication, which is different from other similar cheap products in market. There is  built-in anti-static anti-lightning circuit in the product. This product with sending/receiving indicator is only flash size.
