100Base-FX module (SC plug)
2.
A fiber optic cable is required for the connection. 100Base-FX module is used for the LAN
communication. Dual slots space (i.e., labeled with "C11" and "C12") is occupied when a single
(Port A) module is mounted (see Figure 5.3-5; i.e., space "C12" is not blank). Therefore, the
total number for communication ports needs to be cared.

1000Base-LX module (LC plug)
3.
A pair of optic fiber cables is required. The 1000Base-LX module can be used for the GR-TIEMS
operation or the LAN communication. Use SM mode fiber when long distance is required.

RS485 module
4.
RS485 module has a PCB connector. The module should be connected with a shielded-twisted-
pair cable; it is used for the communication of the IEC60870-5-103. The terminal arrangement
and references are shown below. The cable sheath should be connected with the frame ground
(FG) in the IED case. For the use of the a shielded-twisted-pair cable, the user should note that
the total length should be less than 1200 meter (0.75 miles); the terminal resistor (150 ohms)
should be connected when any connector is not connected. For setting the parameters, see
