Parameter Type Description
Sn Unsigned
long
Board’s serial number.
Freq Pointer to
an unsigned
long
Sampling frequency. The actual sampling frequency will be returned with this
parameter.
ClkSrc Unsigned
long
0: Internal and to External Gate
1: Internal
2: External Clock
3: External Clock and Gate
Burst Unsigned
long
0: Normal Mode
1: Burst Mode
Range Unsigned
long
0: -5V to +5V, Single Ended
1: 0 to +10V, Single Ended
2: -10V to +10V, Single Ended
3: -5V to +5V, Differential
4: 0 to +10V, Differential
5: -10V to +10V, Differential
ChanList Pointer to
an unsigned
long
This is an array of unsigned longs that contains the gains of channels to be
sampled when scanning the ADC sub-system. The max size of the channel list is
64.
GainList Pointer to
an unsigned
long
This is an array of unsigned longs that contains the channels to be sampled when
scanning the ADC sub-system. The max size of the channel list is half the FIFO
depth.
ListSize Unsigned
long
This parameter determines the length the two previous arrays. This is also the
depth of the channel list that is programmed to the board.
ACTIVEX CALL
Long EDREADX.Configure (plong Channels, plong Gains, long ListSize)
Parameter Type Description
Channels Pointer to
an unsigned
long
This is an array of unsigned longs that contains the gains of channels to be
sampled when scanning the ADC sub-system. The max size of the channel list is
half the FIFO depth.
Gains Pointer to
an unsigned
long
This is an array of unsigned longs that contains the channels to be sampled when
scanning the ADC sub-system. The max size of the channel list is half the FIFO
depth.
ListSize Unsigned
long
This parameter determines the length the two previous arrays. This is also the
depth of the channel list that is programmed to the board.
The range code does not apply to the S models, for the are always differential
and bipolar.
The Frequency and ClockSource ADC ActiveX control must be setup before
calling the configure function.
EDREADX.Frequency
Frequency The ADC sampling frequency
