8.1 PUSH BUTTONS
The two push buttons located just above the LEDs can be used to adjust the output voltage
when the output is enabled. These buttons are labelled V▲ and V▼. Short presses for a
fraction of a second adjust the output voltage at the output voltage setting resolution. If the
button is held down, the rate of change increases to around 1V/s after 10s. If both buttons
are pressed together, the button adjust is cleared to zero. The PMBus can read the button
adjust value and also clear the value. The PMBus can also be used to enable or disable the
buttons. Note that it may be necessary to adjust the settings of DCOK and OVP using the
PMBus in order not to encounter these when adjusting with the push buttons over a wide
voltage range.
8.2 FRONT PANEL INDICATORS
The two front panel indicators together indicate the status of the power module.
