It plugs straight into the serial port. The innovate products have two mini phono jacks for serial ports. They are meant to be able to be chained so that you can have a whole string of them communicating to a display (or computer). So, it comes with mini phono to db9 cable that I just plugged into the back of the empeg.
I'm having a small problem where it seems that some garbage is getting sent out over the serial port when it gets set up, causing to wideband to do a free air calibration which, if it happened in the tailpipe wouldn't be a good thing (especially if the engine was running).
I'm not super experience with serial port programming so I might be doing something wrong....



I've attached some screenshots (the sensor isn't in a car at the moment so the data isn't interesting)
