Prolon VC2000 Series - Input Jumper Configuration; Term; Bias Resistors (Jumpers)

M2000 C1050
The VC2000, C1050 and M2000 Prolon controllers come equipped with analog input conguration jumpers that allow
the user to select the signal mode of the associated analog input. These come factory-set for their given application
but can be modied in the eld to accommodate the signal provided by an active transmitter, or when the controller is
reprogrammed into another application with dierent input signal mapping.
