Issue:
Configuring MP503 Universal Inputs
Resolution:
The Rover service tool with MP503 plug-in or a Tracker are the only tools available to configure the universal inputs on an MP503. MP503s ship from the factory with universal inputs configured as 'not used'. Additionally if using an older Tracker, the inputs and output can be configured from the Tracker front panel or the Tracker software.
To calibrate the thermistor input on the MP503, you have to use the front end controller. On the Tracer SC+ this can be accomplished by modifying the offset value of the input.
