Interface Specifications

OpenScale communicates at TTL level 9600bps 8-N-1 by default. The baud rate is configurable from from 1200bps to 1,000,000bps. Most users will use the USB mini-B connection to connect to a computer. See How to Install FTDI Drivers tutorial for more information. Users may also communicate via the 6-pin serial interface:
