How does the KSGER T12 station know which tip is inserted

[Alex Eisenhut]

I was surprised to see ERROR flashing on my screen and I realized the thing needs to have tips enabled by model.
I find this fascinating. How does it know which is which? Is there a heat resistant single wire EEPROM in there somewhere? Does it sense temperature digitally as well to get the most out of that single contact?

No eeprom inside the tip, Probably a table on firmware, with some parameters

It doesn't. You have to select tip manually (press the knob and turn it right).
The reson you got ERROR message is most likely that every T12 tip i had required some "burn-in" time to start working.
There is also no any reliable value you could measure to implement tip type recognition, I'm affraid.

Yeah you're right I must have fooled myself. I just tried enabling and disabling tips and now it makes no difference.
Very odd that such a menu exists, maybe it's for a more advanced tip type.
I also noticed what you say now, every new tip either shows error or has erratic temperature readings while it warms up the first time.
 

Oh well, still a good station IMO.

This menu allows you to define list of tips available for manual selection later.
Just take a look:
And of course every enabled tip can be calibrated individually;)
