int32 DAQmxSetAnalogPowerUpStates (const char deviceName[], const char channelNames[], float64 state, int32 channelType, ...);
Updates the states that analog physical channels on a device are set to when the device powers up or when the device is reset. Power-up states are stored in EEPROMs that you can write to only a limited number of times. Therefore, you should use this function as infrequently as possible. This function writes to the EEPROM only if a setting you request is different from the one currently stored on the EEPROM. This function writes power-up states in sequential order. Therefore, if a physical channel has multiple entries, the last entry is used.
