[Italian LX]

It basically takes up to 4 channels of analog signals (-5v to +5v) and puts them into digital form on a serial data line to be used on your computer. The one I have plugs into a computer's COM port (DB9 connector). They also make one for a USB port; however, I don't think it can work with the TwEECer as of yet.

When you have a DataQ, The TwEECer software is setup to log two additional parameters via the DataQ input. You can wire your wideband to one of the DataQ channels and a boost sensor to another channel.
