ProXR controllers use eight 10K resistors to “pull” the inputs high (+5V) or low (Ground). The integrated resistor network will ensure all inputs are always connected to ground or 5V using the “Pull Up/Down” jumper (as labeled on the circuit board). Installing the jumper in the “Up” position will pull the analog inputs to 5V through the 10K resistor. Likewise, installing this jumper in the “Down” position will pull the inputs to ground. The default jumper setting is in the “Up” position. This will allow the analog inputs to directly connect to switches, which is very useful if you need to manually control a relay from an analog input (See “AD8 Relay Activator / Event Generator” later in this guide).
