f.  Hook the combined plate and switcher into 
the PMK 560 base plate (see figure on page 
40, 
°
). Secure it to the base plate with two 
screws.
ATTENTION:  Use only supplied screws to 
avoid damaging the switcher.
A2. Pull the Cables (at the switcher location).
a.  Gather all the cables from the speakers, AV wall 
plates, MLC 104 IP Plus controller, network, 
and any installed optional devices that have 
been run to the switcher location. Pull them 
down through the ceiling hole and the pipe. 
These cables are:
•  MLC power/RS-232 cable
•  STP AV input cables from the wall plates
•  Speaker cables
•  MLC to projector (IR/RS-232 projector 
control) cable
•  LAN cables
•  Any optional device cables (Aux audio 
input Priority Page Sensor Kit, VoiceLift)
b.  Pull the cables out of the pipe slot towards the 
switcher, ready for connection. Leave the 
IR/RS-232 projector control cable to hang out 
of the bottom of the pipe.
c.  Connect the HDMI output video signal cables 
to the switcher and pull the loose ends down 
the pipe so that they hang out the pipe with 
the IR/RS-232 projector control cable, to be 
connected to the projector later.
NOTE: Do not thread any high voltage 
power cabling, such as power supply 
or projector power cords, through the 
projector pipe. This violates National 
Electrical Code.
