Operating instructions

Local/Remote selector switch

This is a 2 inputs to 1 output selector. It has two
RJ-45 connectors for connection to the local room
central unit and the remote room central unit and
one RJ-45 connector for connection to the local
room system units.
DC power (nominal +48V) on either of the two
input connectors "From Local CU" and "From
Remote CU" will power the whole SZ 6104 plus all
units connected to the SZ 6104 "To Local System".
Both serial data signals and DC-power will be
switched. Selection of Local or Remote can be
made with DIP switch 1 (On: Local selected) and
switch 2 (On: Remote selected).

Note: All the DIP switches on the front panel are
in parallel with the D-Sub control connector. Also
note the truth table for these two control
inputs/switches. Note that in case both are ON
only the Local will be selected.
Normally an EX 6010 Extension power supply is
used as the first unit after the Local/Remote
switch. The DC power supplied to the SZ 6104
from the local or remote central unit shall supply
all units connected to the two switched outputs. If
there is a long distance to e.g. the remote central
unit there might be a significant voltage loss in the
cable if many units are connected to the switcher.
