Ports

Input

# dac — Receiving an array of values that are interpreted as voltage values in volts or current values in milliamperes
``

Details

Each array element corresponds to an output channel with a sequence number: the first array element corresponds to the first output channel, the second channel corresponds to the second output channel, etc.

Data types	`Float64`.
Complex numbers support	No

Parameters

Параметры

# Номер модуля: — unique module identification
