For Immersion EZUHF digital to analog converter ( 0v - 3.3v ) or ( 0v - 5v )
12 bit digital to analog converter (DAC) used to convert pwm signal that come from Immersion EZUHF receiver to ( 0v - 3.3v ) or ( 0v - 5v ) analog output so it can be used on any OSD as analog RSSI (Receiver Signal Strength Indicator). You just plug it in EZUHF receiver where you configure RSSI out channel (usually it is CH8), on other side you plug it in your OSD. Configure your osd that 0v is minimum or 0% RSSI and 3.3V or 5V is full or 100% RSSI. If OSD doesn't have that option, you can plug it in second battery voltage input so RSSI is shown as volatege. 0v to 3.3v or 5v (0v = 0%, 3.3v or 5v = 100%).
