Operation
4.6.3 Multiple Sensor Installation
You may connect up to 32 units as shown below. Before units are in a loop the multidrop address needs
to be defined. Use only one power supply for all boxes in the network to avoid ground loops!
Multidrop Address
Press <Mode> button until <M> appears. Use
<Up> and <Down> to select address number.
Press <Mode> again to confirm.
Alternatively you may also use the DataTemp Multidrop Software, see section 6.3.1
44.
Make sure to deactivate the preset shunt resistor for all units except for the last one. To
deactivate the shunt resistor the S3 must be at position <open>.
