Recently joined in the retro calculator scene and I'm having issue getting the DM16L to power on.
Takes forever to get the thing turned on as the ON button isn't responding consistently.
Sometimes it'll power on and be fine, other times it'll power on and after 1 key press the screen blanks out. (This is all with a new battery)
Additional issue is that, at times, the screen goes all snowy / static. While this effect is variable, it seems to happen mostly when trying to turn the device off. (Screenshot of the display attached showing the snow/static)

Re: DM16L new arrival wont turn on / display spotty
Try a new battery (good brand not a Chinese cheap one).
The included battery should be ok but you never know.

There are only 10 kinds of people in the world: those who understand binary and those who do not.

Thanks - I've already reached out to Michael.
All tests were done with a new battery from the store today as that was my thought too.
I can't even get the display to turn on anymore. I checked if the serial connection works with Putty and that seems fine responding with DM16 ready. However the 't' (display time) command fails with 'fail' and half of the next prompt showing only 'VOY;. I press enter and then I get the full VOYAGER.
Having said that, I'm not sure if it would work for a DM16L. Is there any serial commands people know should work that I can test?

Re: DM16L new arrival wont turn on / display spotty
The 't' should work. Otherwise the '?' command lists out all the commands that it can process. The command set recognized by all of the "Voyager" format units is identical across the range.

Re: DM16L new arrival wont turn on / display spotty
hmmm, 'should work' is never a good sign while troubleshooting.
So I figured I'd try some more troubleshooting. I've reflashed the firstware (DM16_29.hex)
Now the 't' command works, but it only prints the 2020 part of the date. (sometimes only prints '202'
I've also tried the '?' command and just get a 'Firmware' response.

Re: DM16L new arrival wont turn on / display spotty
That doesn't sound good.
Just to make sure, your serial comms are indeed set to 38400 bps, 8 bit, no parity, 1 stop bit, right?

Re: DM16L new arrival wont turn on / display spotty
Yes to all of the above for the putty settings. 38400, 8, 1, none.
I tried different setting for flow control (none & XON/XOFF), but neither made a difference.
I should add that I got the display back, but it's still flaky. Goes back to dotty when trying to turn it off.
The Date display works again. Somethings really amiss with this unit me thinks.
I'll leave it there. No point going further until I hear back from the man himself

Obviously the calculator has contracted the cyber mutation of COVID-19.
