Network Communications
18.1
Introduction
The RS-232, RS-485, Ethernet and the optical communications can be used for networking.
Warning: The calibration counter is incremented when the calibration related settings are changed. This means
that calibration via a serial port cannot be carried out without affecting the certification of a trade installation.
Serial communications parameters like BAUD, PARITY, etc for the RS232 or RS485 serial ports are setup in
the HDWARE menu. The optical communications port is fixed to operate at 9600 baud, no parity, 8 data bits
and 1 stop bit. The optical communications cable must be used.
