FRONT SERIAL PORT (SK1)

The front serial port is a 9-pin female D-type connector, providing RS232 serial data communication. It is situated
under the bottom hinged cover, and is used to communicate with a locally connected PC. It is used to transfer
settings data between the PC and the IED.
The port is intended for temporary connection during testing, installation and commissioning. It is not intended to
be used for permanent SCADA communications. This port supports the Courier communication protocol only.
Courier is a proprietary communication protocol to allow communication with a range of protection equipment,
and between the device and the Windows-based support software package.
This port can be considered as a DCE (Data Communication Equipment) port, so you can connect this port device
to a PC with an EIA(RS)232 serial cable up to 15 m in length.
