We suspected that there's no internal clock on the adapter and the adapter uses a clock from the laptop, but FTDI support confirmed that the adapter has its own internal clock. Apparently they don't activate unless you drop DTR. Specifications: Standard USB 1.1/2.0, EIA RS-485, RS-422 standard USB signals: VCC, DATA+, DATA-, GND, FG RS-485 signals D+, D, GND RS-422 signals R+, R-, T+, T-, GND Working format: Asynchronous, point The communication is fairly simple, the computer sends periodic requests, the device answers them. http://www.ftdichip.com/Products/Cables/USBRS485.htm
I can also attest to its bi-directional communications abilities.

That's the USB to RS485 from FTDI.Pictures of both:They are using an SP481 or ZT485 as the RS485 driver which are really a bad choice, since their data outputs are low

Windows' default serial behavior is different, and it worked out of the box. Ideal for legacy applications which feature UART DB9 based connectors, these modules provide a method of extending the life-cycle of these products by converting them to USB2.0 connectivity, with minimal redesign.The Increasing the delay before deactivating the driver (or even waiting until you have received it) might be a fix, if you can tolerate a long bus turn around time. http://www.nordfield.com/driver-downloads Add To Favorites This feature is only available for registered users.
