0-5V Data Source Char Enum 212 468
NEOFOX_AOUT_VOLTAGE_SOURCE DeviceSetParameter DeviceGetParameter
The 0-5V Data Source parameter is one of the 0-5V analog output settings. The value of this particular parameter sets the
source value for the following formula, which determines the 0-5V analog output voltage. In the formula, the source value
and bound parameters are considered dimensionless scalars – that is, only the actual values matter. The units are irrelevant.
More information about this parameter and how to set up the analog outputs is available in the user manual.
Output (Volts) = ( Source Value – Lower Bound Value ) / (Upper Bound Value – Lower Bound Value) * 5 Volts

4-20mA Data Source Char Enum 213 469
NEOFOX_AOUT_CURRENT_SOURCE DeviceSetParameter DeviceGetParameter
The 4-20mA Data Source parameter is one of the 4-20mA analog output settings. The value of this particular parameter sets
the source value for the following formula, which determines the 4-20mA analog output current. In the formula, the source
value and bound parameters are considered dimensionless scalars – that is, only the actual values matter. The units are
irrelevant. More information about this parameter and how to set up the analog outputs is available in the user manual.
