b.  Connect the IR/RS-232 projector 

communication cable as shown for either 

RS-232 or IR projector control

NOTE:  Some projectors require NULL 

connection wiring, which inverts the Tx 
and Rx connections. See the projector 
guide for details.

IR control for a connected input device such as 
a Blu-ray player can be made through the PVT 
wallplate (see the figure at step 4d).

c.  Connect a network cable (CAT 5, 5e, or 6 

straight through) from the PVS 405D to the 
 RJ-45 LAN jack on the MLC.  
 
The switcher acts as a 3-port Ethernet switch, 
when connected to the LAN. 

á

  Connect the MLC to the projector with an 

RS-232 cable or IR emitter cable, as appropriate.

ó

 Connect to the LAN using a CATx cable.
