Working mode

Two different working
modes can be selected:
- management of a local
RS485 network;
- management of
communication from a single
instrument to PC (RS232);

Data access

By means of RS232 serial
port, RS485 serial port or
RS232 configuration port.

CptBSoft

Multi language software to
program the working
parameters of the transducer
and to read the energies and
the instantaneous variables.
