C.2 Standard Interface Command Set (SICS) Protocol
The T72XW indicator supports the OHAUS CORPORATION Standard Interface Command Set (MT-SICS), which
is divided into four levels (0, 1, 2, 3), depending on the functionality of the device. This indicator supports parts of
levels 0 and 1:

MT-SICS level 0
– Command set for the simplest device.

MT-SICS level 1
– Extension of the command set for standard devices.
A feature of this interface is that the commands combined in MT-SICS level 0 and 1 are identical for all devices.
Both the simplest weighing device and a fully expanded weighing workstation can recognize the commands of MT-
SICS levels 0 and 1.
