*1: Model and Su󰀩x Code specied for 1st/2nd sensor module denes what is printed on the
shield cover, next to the sensor module. Figure 1.3 shows an example of selecting -P1 for
both modules. The following list shows what is printed according to MS code.
-P1: PH
-C1: SC
-C5: ISC
-D1: DO
-D5: DIGITAL SENSOR (cannot select for 2nd sensor module)
-S5: SENCOM SA
-NN: (selectable for only 2nd input. No 2nd sensor module. )
*2: An example when -R (Modbus RTU) is specied.
The next gure shows an example when -E (Modbus TCP/IP) is specied.
