Connect NEP-5000 to SDI-12 logger: 

 

 

Figure 9.8.1.A: SDI-12 Glanded Logger Configuration 

 

1)  Description 

 

When the NEP-5000 sensor is configured as SDI-12 communication, it can offer a full range of 
sensor operations via the SDI-12 bus. Some of these options are initiating and reading turbidity 
measurements,  statistical  measurements,  changing  measurement ranges  and  operating  the 
optical wiper. The user must select appropriate SDI-12 addresses from the PC-Configuration 
software.  

 

 

2)  SDI-12 Selection 

 
 
 
 
 
 
 
 

Figure 9.8.1.B: SDI12 Selection 

 

When  SDI-12  selection  is  being  used,  the  user  must  tick 

(9.8.1.B2)

.  Then  press,  selection 

(9.8.1.B3)

 and 

(9.8.1.B4)

 to save settings permanently to the sensor memory. 

 

For further information regarding SDI-12, please refer to section 

8.2.4 “SDI-12 mode”

 of this 

manual.
