Hi,
i received my PLIN-USB today. I created a small adapter from our PCB-Edge-Connector to an female D-Sub Connector. Everything seems fine, but the PLIN View Software says "Bus-Line: Shorted Ground". But there is no obvious short-cut on my adapter? Do i miss somethgin? Our Vbat is about 12 Volt.

Thanks!

Hi,

on which pins of your D-Sub did you connect Vbat and GND?

Hi,
like described here: https://www.peak-system.com/PLIN-USB.485.0.html

4 LIN
5 GND
9 Vbat

I don't see the problem ...

Thanks!

Hi,

that is ok. Please measure the LIN voltage on the PLIN-USB against GND

best regards

Hi,

we have a 5V LIN Voltage and this is what i measure between LIN and GND...

Hi,

that is not correct. LIN will only work above 6 Volts (typically 8-18V), please see technical spec in the manual for more details. In your post above you say you use 12Volts?

Hi,
thanks for the answer!
Yes, we have an adopted "LIN" since we are not part of the automotive industry. We have a 4-pin connector with GND, LIN, 5V, 12V, whereas the LIN is also 5V.

So it seems, that i need to make an adapter board (5V<->12V)...
Thank you very much for your help!

Hi,
