When selected the RS485 connection, more DPA880 can be connected all together.
In order this to happen, need the all units (connected in net and up to 32) to be identified by
DIFFERENT ID number.
In order the units to have a different ID, need to pre-assign to the all units used in net a specific
ID number.
When selected the RS485 mode, this can be done connecting one by one the units to be used in
net and assigning to anyone of them an ID through the “Configure ID Device” button.
When a Unit is connected, pressing the “Configure ID Device” it is possible to enter a window
allowing to assign to the unit the ID number.
NOTE
: for avoiding problems is highly suggested to work with COM ports number within the 10.
If the Pc will assign to the USB connection a COM port exceeding the number 10, please force to
assign a port from 1 to 9.

the Pc Sw will open:
