Re: Tektronix 485 - no power up
My quick guess is that there is something that draws too much current and triggers the protection circuit. Page 3-11 of the manual shows a sampling/off period of 6+20/450ms so that would cause to click roughly 2 times/sec. If that's how fast the click is heard then it's the protection kicking in. Why... that's another story but should give you a place to start.
You don't happen to have an oscilloscope to test, right? A DMM will not do...
