Review: Great product and price - On initially receiving the unit the output on both serial and USB was corrupted as though baudrate clock not quite set as needed. Seller immediately replaced the device without any quibbles. New part worked fine. Device provides required grounding and possibility to set termination resistance, great in such a device at this price. Great quality in construction as well. Have now tried it in 2-wire 485 and 4-wire 422/485 and found all OK. For the driver on Win10, don't make my mistake - I initially forgot to run install as Administrator and device was not detected. Run install on extracted exe by right click and select "Run as Administrator ..." and all should be good. Review: Works Well with MacBook Pro - The advantage of this unit is that it uses a USB2 B port so if your computer has USB C ports you're not limited to the USB A cable supplied. For a MacBook Pro with USB C ports just dug out the USB C to 2B printer lead and adapter sprang into life enabling configuration and monitoring of the ModBus slaves. ## Features - INDUSTRIAL GRADE - Built-in insulated power supply and ADI signal isolation chip can effectively protect computer damage caused by accidental short circuit, electric shock and other damage. - USB to RS485/RS422: Supports RS-422 (RxD+, RxD-, TxD+, TxD-, GND) and RS-485 (A +, B-, GND) interfaces. - High stability: built-in original FTDI FT232RL chip, maximum speed up to 3 Mbps - Compatibility: Works with Windows 10, 7 (32/64bit), XP, 2003, Liunx, Mac OS Etc. - Warranty: We offer one year warranty and lifetime technical support for this isolated USB to RS485 RS422 converter.
