I purchased one of these used and seem to be having some trouble. Just curious if anyone has experienced the following:
1) In testing with LEDs for the eject charges, the altimeters starts up, then beeps out the expected beeps for battery charge and last flight altitude then it delivers a low set of long beeps continuously. When I boot it up and hook up the LEDs after it is booted up, it beeps the correct sequence reporting continuity on the main and drogue outputs.
2) When I hook up the computer interface, it just delivers a long beep and seems to be locked up.
Just curious if anyone has had anything similar.
