Communications Technology Option
The plug-in COMMS Technology Option provides a serial data port, allowing Inverters to be
linked 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 Inverter in the system.
Refer to the Communications Interface Technical Manual for further details.
ConfigEd Lite
This is Parker SSD Drives’ Windows-based block programming software. It has a graphical
user-interface and drawing tools to allow you to create block programming diagrams quickly

Connection to the P3 Port
The port is an un-isolated RS232, 19200 Baud, supporting the standard EI bisynch ASCII
communications protocol. Contact Parker SSD Drives for further information.
• Frame B : The P3 port is on the front of the unit and is used by the Operator Station.
• Frame C, D & E : There are two ports - one is used by the Operator Station, and the second

Using any P3 port on the drive, parameters can be monitored and updated by a suitable PC
programming tool, e.g. ConfigEd Lite.
