9.1.4 Testing AI in “Voltage” Mode
Connect an AA battery (1.5 VDC) on the AI-1 on System-1 (see Figure 48) and a voltmeter on the corresponding AO-1 on
System-2. Make sure the polarity is correct while connecting the battery. Measure the voltage on the Analog Output on
System-2. It has to indicate 1.5 VDC.

9.1.5 Testing AO in “Voltage” Mode
To test an Analog Output in “voltage” mode the following can be performed. Refer to “Appendix E: Zlinx Wireless I/O Models
and Features” for the list of Analog Output modules. On the corresponding Zlinx Wireless I/O device on System-1 connect an
AO to a voltmeter as shown in the figure below (Figure 49). Supply a voltage signal on the AI side of System-2. Confirm on
System-1 with a voltmeter that the voltage on the corresponding output matches the voltage input.
