This section will use OME-A-822PGL to link OME-DB-889D.
The major steps are listed below:
Step 1: Hardware installing.
1. Turn off power of computer.
2. Plug in OME-A-822PGL then connect 37 pin cable & 20 pin flat cables to CN1

2. Setup OME-A-822PGL: Bipolar mode , Gain = 1 , Analog input channel = 0 ,
Trigger mode = Polling mode.
3. Send digital output of OME-A-822PGL data to control OME-DB-889D
D0~D3: OME-DB-889D channel selection, D4~D6: OME-DB-889D Gain setting
4. Reading OME-A-822PGL analog input data
5. Conversion data to voltage or temperature
