Communications Technology Option
The plug-in COMMS Option Technology Box provides a serial data port, allowing Converters
to be linked together to form a network. Using a PLC/SCADA or other intelligent device, this
network can be continuously controlled to provide supervision and monitoring for each
Converter in the system. Refer to the Communications Interface Technical Manual for further
details.

UDP Support
The P3 port can be used to transfer an ASCII representation of the converter's settings between
the Converter and a host computer.
The transfer uses a simple ASCII file structure and XON / XOFF protocol. This is provided by
most communications packages. Host computers tested include IBM PCs XT/AT, running both
Windows and MSDOS, Psion Organiser 3 and many more.
Transferring data from the Converter to a host computer is defined as “Downloading” ,whereas
transferring data from a host computer to the Converter is defined as “Uploading”.
Refer to Chapter 6: “Programming Your Application” - SYSTEM PORT P3 for parameter
details.
