Configuring the DAQCard-1200
Because of the NI standard architecture for data acquisition, the
DAQCard-1200 is completely software configurable.
Data acquisition-related configuration, which you must perform, includes
such settings as analog input coupling and range, and others. You can
modify these settings using NI-DAQ or application-level software, such as
LabVIEW and Measurement Studio.
To configure the device in Measurement & Automation Explorer (MAX),
refer to either the
DAQ Quick Start Guide or to the NI-DAQ User Manual
for PC Compatibles .
Configuring Analog Input
At startup, the DAQCard-1200 defaults to the following configuration:
• Referenced single-ended input mode
• ±5 V AI range
Table 2-1 lists the available AI configurations for the DAQCard-1200 and
shows the default settings.
The analog input circuitry is software configurable.
Caution Connections, including power signals to ground and vice versa, that exceed any
of the maximum signal ratings on the DAQCard-1200 can damage the card and computer.
NI is
not liable for any injuries or damage resulting from incorrect signal connections.
