This Ethernet / RJ45 socket is a 10/100-Mbaud Ethernet
interface permitting communication with a SUSI client like
ARENA AX , ARENA NX , COACH
(as per IEEEC 802.3)

RS485 Interface
General
The CLIF-CBUSLC has one C-Bus interface:

RS485-1 (consisting of push-in terminals 24 [GND-1], 25,
and 26) is isolated.
RS485-1 Bias and Termination Resistors
RS485-1 is equipped with a three-position slide switch which
can be used to switch its bias resistors OFF (position "MID" –
this is the default and the only allowed setting), ON (position
"BIAS"), and ON with an additional 150Ω termination resistor
(position "END").
3-POSITION SLIDE SWITCH
