Yes, I check with the scope.To open is same as the 390B. Dont' forget to remove stickers to view all screews...Wire directly sold and comes by the holes.SO I think that :- White is power (apply voltage (by a resistor) switch on the unit- gray is ground (directly connect to battery)- I think magenta is an output. stay to ON level ( 2.8V) even is pulldown resistor, and make "reset" display if connected to ground :o(- blue and green are input. Blue is 0v and become 1 with pullup resistor. Green same but reverse (2.8V and become 0 with pulldown resistor)I will compare with 390B when I will have it...
I found 390B ! (more expensive I confirm (double than 390B+), but finaly less than a 390b+ can not use ;-))Have a look herehttp://fr.aliexpress.com/item/UNI-T-UT390B-Laser-Range-Finder-Distance-Meter-Area-Volume-LCD-Meter-0-05m-45m-Laser/1823766667.html?spm=2114.06010108.3.19.dGQsJn&ws_ab_test=searchweb201556_1,searchweb201644_4_505_506_503_504_301_502_10001_10002_10017_10010_10005_10011_10006_10003_10004_10009_401_10008,searchweb201560_2,searchweb1451318400_-1,searchweb1451318411_6452&btsid=261d0cd5-81ac-41f4-9d7d-8b31187e7903
Hello AllCorrection : I have an UT390B+ (not 380). So I disassemble it.GND, and power are identified.It seams to have 1 output, and 2 inputs.But even trying all RS232 speed, set one input to 1 or 0 during sending command, nothing never append :o(So at this time, no success.I order one UT390B (hop to receive it). I will try to compare with ...So as soon as I found something I'll tell you !....
Thanks for your comment of my first projet exposed here. I have a look about yours. Very nice and original !

Hello dir all.I just buy an UT380B+ (because UT390B not available). So I try to identify the debug pin assignement but except GND and POWER (not the most difficult ;o)), I didn't identify the other... I check all pins at power on but nothing send at the startup. So not possible to simply identify the tx pin :o(Some one try to use it or knows if it's possible to dial by rs232 (ttl) port ?Thanks a lot if yes...
