Application
and functions of digital modules:
- measuring units [g], [kg], [t];
- tarring in all measuring range;
- changeable speed of transmission between 9600-57600bit/s;
- possibility of addressing;
- restoring default setting by putting on the jumper;
extended communicational protocol;
- protection against access to factory parameters (jumper).
Digital modules are applicable in extended weighing systems
connected in network by RS485 and controlled by a supervising
computer (system):

| P1,
P2,... Pn |
-
weighing platforms with 1 or 4 load cells
(minimal resistance of load cells 90  ). |
| MC1,
MC2,... MCn |
