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 4.3-7; 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 and Modbus. 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 Chapter
