AOGND是模拟输出通道的接地参考信号。
DAC<0。。7> OUT和EXTREF都引用到AOGND。
外部参考信号可以是直流或交流信号。这个
设备将此参考信号乘以DAC代码，再除以
满标度DAC代码，用于生成输出电压。
图4-2显示了如何将模拟输出连接到
装置

数字输入/输出信号连接
数字输入/输出信号为DIO<0。。7> 和DGND。DIO<0。。7> 是
构成DIO端口的信号，DGND是地面参考信号
对于DIO端口。您可以将所有行单独编程为输入或

此类信号连接导致的任何损坏。

AOGND is the ground reference signal for the analog output channels. DACOUT as well as EXTREF is referenced to AOGND. The external reference signal can be either a DC or an AC signal. The device multiplies this reference signal by the DAC code, divided by the full-scale DAC code, to generate the output voltage. Figure 4-2 shows how to make analog output connections to the device. Figure 4-2. Analog Output Connections Digital I/O Signal Connections The digital I/O signals are DIO and DGND. DIO are the signals making up the DIO port, and DGND is the ground reference signal for the DIO port. You can program all lines individually to be inputs or outputs. Caution Exceeding the maximum input voltage ratings, which are listed in Table 4-2, can damage the device and the computer. National Instruments is NOT liable for any damages resulting from such signal connections.
