The following diagram applies only when the optional Resisitve Resistive Sensor mezzanine board is in place.
Using the screw (SW1) on the mezzanine board, the OP7818 can be set to operate with a thermistor or resistive sensor. Note that with the mezzanine board in place, there can be no jumpers on pins for jumper array (J4) and SW2 and SW3 screws must be in the off position and switch SW4 is in Current mode (position I).
In Resisitive Resistive sensor mode, the screw must be turned to the left, to RTD.

The faceplate provides a DB37F connector (see “Connector “Connector Pin Assignments” for details) and a series of status LEDs.
