software command (MT-SICS).
For Category 2, either an RS232 or RS422/RS485 interface is available, based on the ordered option. For
Category 2 it is not possible to operate both interfaces in parallel.
The communication protocol of the load cell is MT-SICS. MT-SICS is a proprietary protocol defined by
