SDI-12/ MODBUS RTU Channel (D2) 

A single connection for both SDI-12 and MODBUS is available in this connector. 

Figure 32: 6-pin Serial Inputs Connector 

For SDI-12 input, users may refer to the following figure for wiring configuration. They may connect up to 2 sensors to the 
logger using the same wire (pin out). The logger support up to 8 addresses for SDI-12 (

– 7

), three additional 

measurements (

M1!

 

– 

M3!

). 

 Twenty parameters are supported on the main measurement (

M!

) and nine parameters for the additional 

measurements. In total the logger may provide reading for 32 parameters per sensor. 

Figure 33: SDI-12 Channels 

– Wiring Configuration 

The logger supports RS485 connection on MODBUS RTU protocol, please use the following figure for wiring 
configuration. Users may connect one MODBUS sensor with a maximum 16 parameters. The logger support four 
MODBUS functions (coils, discrete inputs, holding registers, input registers), however there is only a single setting 
because the reading is based on block read. 

Each register may be set into specific number and bit number: 

-

16 bit (integer, unsigned integer)

-

32 bit (long integer, long unsigned integer, floating point)
