For the voltage of the LEDs apply a factor of 18,46. | ## Example | Query | Response | Action | | --- | --- | --- | | VT | vt 24758,0,1347,1343,1350,1350 | Displays the current values: Supply voltage: 24,758 mV Analog input voltage: 0 mV LED voltage at channel 1: 1,347 mV × 18.46 = 24,866 mV LED voltage at channel 2: 1,343 mV × 18.46 = 24,792 mV LED voltage at channel 3: 1,350 mV × 18.46 = 24,921 mV LED voltage at channel 4: 1,350 mV × 18.46 = 24,921 mV | | SV 22000,25500 | sv 22000,25500 | The new values are set: - 22000 mV mimimum level - 25500 mV maximum level |
