5.1.13.1. SPA/IEC_103 communication on the rear connector X3.2
The 9-pin D-type subminiature male connector (RS-232 connection) on the rear
panel connects the feeder terminal to the distribution automation system via the SPA
bus or the IEC_103. The fibre-optic interface module type RER 123 is used for
connecting the feeder terminal to the fibre-optic communication bus for SPA and
IEC_103 protocol.
5.1.13.2. DNP 3.0/Modbus communication on the rear connector X3.2
1
The 9-pin D-type subminiature male connector (RS-232 connection) on the rear
panel connects the feeder terminal to the distribution automation system via the
DNP 3.0 or the Modbus protocol. The interface between the feeder terminal and a
RS-485 communication bus can be made through the RER 133 Bus Connection
Module. The interface between the feeder terminal and an optical bus can be made
through the RER 123 Bus Connection Module.

Equipment connected to the rear communication ports X3.2 and
X3.3 should be galvanically isolated from the terminal.
1. DNP 3.0 and Modbus communication is supported in the feeder terminal revisions
of Release 3.0 or later (using RER 133) and Release 3.5 or later (using RER 123).
