Serial communication connections

The optical front connection of the relay is used to connect the relay to a SPA bus
via the front communication cable 1MRS050698. If a PC compatible to the IrDA
Standard specifications is used, wireless communication is possible as well. The
maximum wireless operating distance depends on the transceiver of the PC.
Rear communication of REM 610 is optional and the physical connection varies
with the communication option.
Plastic fibre-optic connection
If REM 610 is provided with the optional fibre-optic communication module for
plastic fibre, the fibre-optic cables are connected to terminals X5.3-RX (Receiver)
and X5.3-TX (Transmitter).

RS-485 connection
If REM 610 is provided with the optional RS-485 communication module, the cable
is connected to terminals X5.5/1-2 and X5.5/4-6. The connection socket is a 6-pin
header-type socket and the terminals are of screw compression type.
