6 Installation of FLUXUS G704
6.9 Connection of the Serial Interface
The RS232 interface is located on the front plate of the flowmeter (see Fig. 6.15).
The flowmeter can be equipped with an RS485 interface (option). Connect the RS485
cable to the terminals A+ and B- and terminal 101 of terminal strip KL4 (see Fig. 6.15).
For further information on the data transmission see chapter 13.

6.10 Connection of the Sensor Module (SENSPROM)
The sensor module contains important transducer data for the operation of the flowmeter
with the transducers. It is connected with the corresponding terminals of the flowmeter.
If transducers are replaced or added, the sensor module has to be replaced or added,
too.
