Hi, I am trying to connect an HTI-96min hydrophone to the audiomoth PCB. I also wanted to power the unit with a battery pack. I was successful in soldering everything but ran into a problem. After configuring the device with the app and switching to Custom mode the green LED was flashing as it should but when it was supposed to record the red led blink twice and then both lights were flashing as if it had not been able to read the configuration. It recorded an electric signal but no sound. I have attached pictures of the Configuration file and the work I did. I think I may have soldered the mic in the wrong configuration or maybe the hydrophone needs a separate power source. I have attached a word document showing my work as well as the sounds recorded. I believed cable 1 was positive, Cable 2 negative, and Cable 3 signal.
Please advice. Thank you
These are all very helpful comments. I ran a bench test and everything was working fine. When I came back from the field I was tired and clumsily pushed the switch from custom to default by accident and then to USB/off again. That may have erased all the previously collected data.
I also tried to look at the comments in the files like the picture you sent but cannot see it. I am using windows and I thought I could reach that windows through the Properties menu. Thank you for your response. I will do another attempt at the field test and keep you posted.
Hi, One of the files here was recorded before you set the time. It was recorded in DEFAULT mode and then stopped recording when the switch was immediately moved back to USB/OFF.
