RS-485 TO USB CONVERTER

brand : ACREL COMPANY

U-485 is USB to RS485 converter to realize communication conversion from USB to RS485. The power supply of the product is from the USB port, and no external Power. Use the unique zero-delay automatic sending and receiving conversion technique and baud rate adaptive technique. Plug-and-play, suit for all software, and a Transceiver enable control. And 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 a built-in anti-static antilightning circuit in the product. This product for micro-design, size is as the same with the flash, antistatic and anti-lightning circuit was built-in, uniquely with sending/receiving indicator lights.
