Protocol

The device has a mini-USB connector for PC connectivity. It ships with a Prolific USB-to-serial cable (i.e. the Prolific chip is inside the cable) which can be attached to that connector.

The device accepts a simple command-based protocol over the (virtual) serial port, using a baudrate of 9600 baud, with 8e1 settings (8 data bits, even parity, one stop bit).
