An arbitrary potentiometer with linear characteristics and resistance 1 to 10 k
Ω
can be
connected. It must be connected with 3 poles. The device measures the total resistance
when powered up and then converts it to the required brightness range.
RS485–/+ and CAN L/H must be carried out as twisted pairs!
The CAN bus and the RS485 bus must be terminated each by resistors 120
Ω
on the
first and the last bus participant!
