% SETDAQ Sets the data acquisition hardware.
%   MpSys = SETDAQ() sets the hardware to record a signal from Channel 1 at
%   10000 Hz, using the MP160 System and the UDP.
%
%   MpSys = SETDAQ(3, 500, 101) sets the hardware to record a signal from
%   Channel 3 at 500 Hz, using the MP150 System and the UDP.
%
%   See also SETAPI.

%
% === DESCRIPTION =========================================================
% This function sets the data acquisition (DAQ) hardware before the
% recording. This function is used along with setApi().
%
% INPUT
% - acqCh       Acquisition channel. The default is Channel 1.
% - fs          Sampling frequency in hertz. The default is 10000 Hz.
% - mpType      Type of DAQ hardware. The default is 103, which refers to
%               the BIOPAC MP160 System - see the BHAPI Manual for more
%               information.
% - commMethod  Type of communication between the DAQ hardware and the
%               computer used for the recording. The default is 11, which
%               refers to the UDP (Ethernet cable) - see the BHAPI Manual
%               for more information.
% OUTPUT
% - MpSys       Structure array with all the settings for the DAQ hardware.
