4 STANDARD ETHERNET COMMUNICATION
The type of Ethernet board depends on the chosen model. The available boards and their features are
described in the Hardware Design chapter of this manual.
The Ethernet interface is required for either IEC 61850 or DNP3 over Ethernet (protocol must be selected at
time of order). With either of these protocols, the Ethernet interface also offers communication with MiCOM
S1 Studio for remote configuration and record extraction.
Fibre optic connection is recommended for use in permanent connections in a substation environment, as it
offers advantages in terms of noise rejection. The fibre optic port provides 100 Mbps communication and
uses type BFOC 2.5 (ST) connectors. Fibres should be suitable for 1300 nm transmission and be multimode
50/125
µm or 62.5/125 µm.
The unit can also be connected to either a 10Base-T or a 100Base-TX Ethernet hub or switch using the
RJ45 port. The port automatically senses which type of hub is connected. Due to noise and interference
reasons, this connection type is only recommended for short-term connections over a short distance.
The pins on the RJ45connector are as follows:
Pin Signal name Signal definition
1 TXP Transmit (positive)
2 TXN Transmit (negative)
3 RXP Receive (positive)
4 - Not used
5 - Not used
6 RXN Receive (negative)
7 - Not used
8 - Not used
