data cable for digital indicator gauge?
« on: December 21, 2024, 11:30:22 pm »
I recently got a 1" (25.4 mm) travel digital dial indicator that reads out in mm or inches. It has one little door holding a button battery, and it seems to have an un-advertised feature hiding behind door #2, which looks like 4 PCB edge contacts, likely for a data transfer cable. I assume this is something that someone uses in some factory tooling somewhere. Possibly logic-level RS232 data, but the company isn't interested in supporting it for all customers so they don't sell the cable for it. Anyone hacked into this?  The brand is "Qnkaa".
I got it as Amazon item# B0CC5JVM3V Electronic Digital Dial Indicator with Magnetic Base Holder Fine Adjustable Long Arm 0-1" / 25.4mm Inch/Metric Conversion Professional Gauge 0.01mm/0.001"

Yes, that one is the closest thing I found, but in the photos you can see the indicator end of that cable assembly uses a micro-USB connector, while my meter has only 4 flat pads on the PCB. I agree it is plausible they could actually be electrically, if not physically compatible.

Hi,

if you don't mind attaching a connector this might help:

Excellent, thank you! I see this meter has indeed been analyzed and the data port can work, that is exactly the information I was hoping to find.

regards,
John
