Hi to all !! Got my OpenLogger and installed Digilent Agent on my Windows 10 notebook. No errors. 1. Then followed line by line the Getting Started instructions. Have come stuck at the Device Identification via Agent. I just get a message " Error connecting to device " . What could be wrong ?? 2. Am I supposed to power up the board or only the USB cable is enough ? When exactly one use the DC power socket for power up? The manual is sadly silent on this ... 3. Instead of the Web based Waveforms Live how to host it locally on my PC ? When I try to enter http://localhost:42315 into Chrome browser I get a 404 response. I even tried to run the Agent in WIN8 compatibility mode. No use... SO what else do I need to check
I am using the network analyzer on the Analog Discovery 2, and have had two separate device failures occur. They have both happened at low frequencies (the start of the bode sweep). The maximum output voltage is in the range of 2-3V from the source device but a bad connection at the input can cause a transient spike that I presume reaches above the maximum allowed input causing the problem which essentially locks one of the traces at 25Vdc. There is no DC voltage present and the scope probes are AC coupled. I am reasonably sure that some sort of transient spike is causing this and I occasionally get the “out of range” warning on the first couple of sample of the bode plots. I have installed a pair of 1W 15V zener diodes back to back across both inputs of the BNC connector to prevent any type of transient overload which should prevent any possibility of exceeding the maximum input voltage on a transient basis. Can you offer any additional insight or confirm that the diodes are the best method of additional overvoltage protection? Any help is greatly appreciated! Regards, Jared
