5. Setup

5.1. Power Input Selection

The receiver supports two voltage ranges: AC/DC 9V-30V and AC 85-250V. It is crucial to set the Power Input Selector (PIS) correctly based on your power supply. Refer to the markings on the device. If the input voltage is greater than 24V, shorten pins 2 & 3. If the input voltage is less than 24V, shorten pins 1 & 2. This selection is typically done via a jumper or switch on the board.
