Different channel types contain additional configurable settings. These settings are grouped together

For DAC channels, the mode indicates the output of the channel (function and range). The output is
switched off before any mode change is made, and remains off after the mode has changed. The
following modes are supported:
• channel.MODE_VOLTAGE_1 or 17
