Hi,
I've a couple of questions regarding wiring of the E888 expander unit.
The manual states that the digital inputs should be pulled to ground. Is that the 0V signal ground or the chassis ground ( Battery -)?
Pin B14 has the function 0V Comms. What is the intention of this pin and in which application can it be used?
Is it internally connected to pin B21 (0V) so I can use it as an additional sensor 0V?
Thanks,
Rolf
