8.8 Configure by Remote PC (Configuration Port Interface or CPI)
The instrument provides an optional method to communicate with a PC host system to
access each single operative and configuration parameter or to upload/download the
complete instrument parameter set.
The optional system consists of:
•
Dedicated adapter that interfaces the instrument to a RS-232 line.
•
External wall power supply, to avoid powering the instrument through the main line.
•
Receptacle for the five pins clip, located on the side of the instrument package; a
mechanical polarization prevents incorrect insertion.
•
PC configuration software.
When the Configuration Port Interface (CPI) is connected, all instrument functions are
disabled. While connected, the device is in ‘remote’ mode for all parameter configuration,
no matter the local security code settings.
The CPI connection is performed using a Modbus RTU protocol with fixed communication
parameters (device address 255, data format 8 bit without parity and 9600 baud). The
wall power supply for the CPI adapter has three different interchangeable plugs to
accommodate US/Japanese, European and UK sockets. The CPI can also be used also
for field upgrades of the instrument firmware. A USB/RS232 converter is compatible with
the CPI.
