Seeed-Studio-MR60BHA1-Sensor gp1 and gp2 pins

I have two of the mmwave 60 gig heartbeat detectors. To start I want to just use the two gp1 and gp2 pins that are supposed to be for motion and occupancy. Do these work? Do I need a pull down or a pull up resistor on these? Can I power up the unit and just use these two output pins or am I forced to use the serial communications?

HI, we recommend you use a serial connection
