4.2.2 Serial communication connections
The relay is interfaced with a fibre-optic SPA bus by means of bus connection module
RER 103 via a 9-pole, D-type subminiature connector X2 located on the rear panel of
the device. The terminals of the fibre-optic cables are connected to the counter
terminals Rx (Receiver) and Tx (Transmitter) of the bus connection module. The
fibre-optic cables are linked from one relay to another and to the substation level
communication unit, for instance type SRIO 1000M.
The optical PC-connection on the relay front panel is used to connect the relay to a
fibre-optic SPA bus via an opto-cable 1MKC950001-1.
