Data points must be comma delimited. The last character in a sequence indicates how the data is to
be output. If the last value is
the character ‘S’, the output scan will stop. If the last value is the
character ‘R’, the output scan will loop back to the starting point and continue to run until stopped by
the user.
Output data format:
Value 1, Value 2, Value 3,…,Value n, S
 Output the data sequence once, then stop.
Value 1, Value 2, Value 3,…,Value n, R  Output the data sequence continuously.
Example 1:
Analog output range set to 0 to +5V
Data = [0,1,2,3,4,5,R]
A stair step-up waveform will be output continuously.
Example 2:
Analog output range set to 0 to +5V
Data = [5,4,3,2,1,0,S]
A stair step-down, one shot waveform will be output.
To save or retrieve the programmed output data from the host computer, click on the [Save Buffer
Data To File] or [Open Buffer Data From File] button.

20 analog output data values have 12-bit resolution, which equates to a full scale range
input of 0 to 4095 counts. This count range can be scaled to any engineering units on a per-channel
basis. The default output range for the voltage output module is -10V to 10V and the default scale
factor is 1 which yields an output range of -10V to +10V. This mapping can be changed using the
scale factor.
