Integrating the Yieldpoint d-Exto MPBX

 

Subsequent channels would be configured with each d-Exto position. An example for channel 2 is shown in 
Figure 9. 

 

(Figure 9) 

 

Multiplexer Configuration

 

If more channels are required than can be supported using Direct Connect configuration then a multiplexer may 
be configured. The multiplexer configuration simply acts as a placeholder for the measurements. 

Use the 

Multiplexers button

 on the Program tab to display the Configure Multiplexers form.  

Select 

Virtual

 as the Model and 

Digital

 as the Gage Type, as shown in Figure 10.  

The Channels configuration will determine how many channel placeholders will be available. If the temperature 
(Upper Channel configuration) of the d-Exto will be read then the maximum Channels will be 16 x 4 Wires. If no 
temperatures are to be read the maximum Channels will be 48 x 2 Wires.
