It has a Terminal Block connector for LIN communication, LIN bus power supply Vs, LIN bus input / output data line and LIN bus ground GND.
Do I need to supply voltage (12v) on Vs in both use cases: master and slave or it is required for master only?
Could you provide the link to the item in documenttaion for that?

Hi,

You should supply external voltage to Master only, please have a look at the following document :

Hi Filip, thanks.
With Vs pin is clear now.
What about WK and EN pins?
Am i right, to start send LIN frames - I need to set high on EN pin before?
To move it from Stand-By mode to Normal Operation mode.
And what about WK?

I'm asking, since there is no any description of initiaization step for LIN click.

Hi Filip,
looks like Vs=12v should be supplied to slave as well as master - according to scheme https://download.mikroe.com/documents/a ... c-v100.pdf
I did that - and now i see the data on slave from master.

Hi,

Are you supplying the LIN clicks with 12V?
