4691	2020-08-24	Factory none	Disposed	Disposed none	Apogee found manufacturing defects and will send us a replacement NDVI sensor.
4557	2020-07-13	Lab none	Tested	Lab none	I tried to talk to the sensor with the new Apogee SDI-12 to USB dongle and Apogee software - no luck. The same method worked just fine foe the new NDVI sensors. Next will be to return them to Apogee for evaluation.
4524	2020-06-11	Lab none	Tested	Lab none	The two red/far red sensors stopped working on the BA tower. I tested them on the CR1000 in the lab running the BA program and still got no response. I tried the CR1000 terminal to talk to them over SDI-12 and got nothing trying both C1 and C3 ports. I will get a USB to SDI-12 from Apogee soon and will try again with that.
