National Instruments SCXI -1125 用户手册

© National Instruments Corporation

After parallel mode has been configured in software, you can scan the 
SCXI-1125 channels by entering the corresponding E Series DAQ device 
channels or a sequential SCXI channel string in the channel parameter in 
the analog input application. You can also enter virtual channels; however, 
in parallel mode, virtual channels containing CJC are disabled in MAX.

When using a C-based ADE, you need no special steps for configuring the 
chassis, the SCXI-1125, or the E Series DAQ device for parallel scanning. 
You still have to configure the gain and filter settings by using 

SCXI_Set_Gain

 and 

SCXI_Configure_Filter

. You can use any of the 

E Series DAQ device analog input functions to get the data from the eight 
channels of the SCXI module. After scanning, convert the binary data to 
voltage data by using 

SCXI_Scale.

 Refer to the NI-DAQ User Manual for 

additional information on parallel scanning of SCXI modules.

Refer to the ADE manual and the DAQ analog input examples that 
come with your application software for more detailed information on 
programming the SCXI modules for scanning in multiplexed mode.

Many example programs ship with NI-DAQ. For more example 
information on how to create tasks and channels, refer to the example 
programs. By default, the example programs are installed in
