OME-DB-889D Multiplexer Board  
1. Function Description  
The OME-DB-889D is an expansion multiplexer / amplifier board for use with  
OME-A-82X, OME-PCI-1800 series. Each OME-DB-889D multiplexes 16  
differential analog input channels into one analog input of the DAS board. The high  
grade instrumentation provides software programmable gains of 0.5, 1, 5, 10, 50, 100,  
500 and 1000.  
Thermocouple measurements are handled easily with OME-DB-889D. The  
board includes cold junction sensing and compensation circuitry that provides a  
scaling of 24.4mV/°C. Biasing restores are includes for open thermocouples  
detentions of voltage measurements or 112 channels of thermocouple measurement.

3.3. The Thermocouple Input  
The OME-DB-889D can accept thermocouple sensor to measure temperature.  
The OME-DB-889D should be set to different gain value if use different  
thermocouple type.  
If you are usingOME-A-82XPGL series multi-function bard to linked  
OME-DB-889D you have got the gain as:  
Gain = OME-A-82X Gain X OME-DB-889D Gain  
OME-A821PGL Gain = 1 , 2 , 4 , 8  
50 , 100 , 1000  
OME-DB-889D Gain = 0.5 , 1 , 5 , 10 ,

3.3.1 Voltage - TO - Temperature Conversion  
The temperature-versus-voltage relationship of a the thermocouple is not linear.  
You can reference the thermocouple reference tables to get V to T values. Or  
use temperature conversion equation to get V to T values.  
Temperature Conversion Equation:  
T = a0 + a1 x + a2 x^2 + a3 x^3 + a4 x^4 + …….. + an x^n  
where  
T = Temperature  
x = Thermocouple Voltage  
a = Polynomial coefficients unique to each thermocouple

3.3 CJC Output  
The OME-DB-889D provides Cold-Junction Compensation (CJC) for the  
thermocouple applications. If the CJC is required, place the JP17 in the position of the  
channel to be used as a CJC reference. If the CJC is not required, Place the JP17 in  
the position “X”.  
CJC has output on connector CN7. Using a voltage meter measures CN7 which exists  
a voltage related to the OME-DB-889D board temperature. The CJC voltage transfers  
to temperature with formula:  
T(°C) = V*1000/24.4

4.4 Open Thermocouple Detection  
The OME-DB-889D provides open thermocouple detection through a resistor  
circuitry. These resisters are normally not connected. The user can find on the back of  
the board has two solder gaps for each input channel. If you short the solder gaps, the  
open thermocouple detection is enabled.

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  
and CN3 of OME-DB-889D.  
3. Setup OME-DB-889D (Ref. Jumper setting section of OME-DB-889D. The  
example program uses default setup )  
4. Connect your signal wiring.  
5. Turn on your computer power.  
6. Installing OME-A-822PGL C library.  
7. Now you are ready to programming.  
Step 2: Software programming (C Language)  
1. Using OME-A-822 library function to initial OME-A-822PGL  
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  
Note:  
The OME-A-82X series programming steps are same as those for the  
OME-A-822PGL

6. Calibration  
The OME-DB-889D is calibrated to its best of operation. For environment subjected  
to large vibrations, recalibration is recommended. Before calibrating the  
OME-DB-889D, user should consider having the following available:  
z One 6 digital voltage meter  
z One temperature meter  
z One OME-A-82x series multifunction card  
6.1 Calibration VR Description  
There are two VRs on the OME-DB-889D.  
VR Num.  
VR1  
Description  
Amplifier Offset adjustment  
CJC Gain adjustment  
VR2  
6.2 Calibration Steps  
1. Turn off computer power.  
2. Connect OME-A-822PGL (Or any OME-A-82x series multi-function card) to  
OME-DB-889D.  
3. Setup OME-DB-889D to default setting  
4. Short CH0HI to CH0LO to A.GND of DB889D.  
5. Connect probe of voltage meter to CN7 (CJC output: + , A.GND : - ).  
6. Turn on computer power  
7. Wait about 5 minute (warn up).  
8. Run Calibration program of OME-DB-889D.  
9. Close the probe of temperature meter to OME-DB-889D them reading  
temperature value.  
10. Adjust VR1 until the screen value = 0;  
11. Adjust VR2 until voltage meter reading value = temperature value X 2.44mV
