3.6.6 Configuration via push button on front panel of analog extension
The values or configurations of the inputs/outputs can be displayed or altered by pressing the
push button on the front side of the product.
When you first press the push button, the display shows the number and value of the channel
currently selected.
When you press the button again, the configuration of that channel is displayed.
Press again, this time holding the button down for longer than 10 seconds. The display of the
channel configuration will begin to blink. After that, further pushes on the button will alter the
configuration. At this stage, whenever the button is not touched for 10 seconds the
configuration last reached will be saved to EEPROM. The display then automatically changes
to the next channel.
