Hello,
I have a question on the additional pins placed on the board of the liquid controler K2639 .
i.e.: pin A, B, C , D and VR1 what are they used for?
Best regards
Jack
These were used to connect the unit to a computer interface.
hello thanks for the tip but …
can you give me more details about these.
What type of connection to what unit etc
type of output?
best regards
Jack
Apparantly these outputs were used in the past with the Velleman K2611 interface.
This device has been obsoleted 14 years ago, so I’m afraid there is no further info available.
