NOTE:  If making network connections to the Cresnet peripherals, refer to the latest 
revision of the Crestron Network Modular Cable Requirements (Doc. 5682). This 
document can be obtained from the Downloads page (CABLES and MANUAL 
Libraries) of Crestron’s website (www.crestron.com). Search for MODULAR.PDF. 

When calculating the wire gauge for a particular Cresnet run, the length of the run 
and the load factor of each network unit to be connected must be taken into 
consideration. If Cresnet units are to be daisy-chained on the run, the load factor of 
each unit to be daisy-chained must be added together to determine the load factor of 
the entire chain. If the unit is a home-run from a Crestron system power supply 
network port, the load factor of that unit is the load factor of the entire run. The 
length of the run in feet and the load factor of the run should be used in the following 
resistance equation to calculate the value on the right side of the equation. 

R   =  R esistance (refer to next table).

L   =  Length of run (or chain) in feet.

LF =  Load factor of entire run (or chain).

R     <

L x LF

The required wire gauge should be chosen such that the resistance value is less than 
the value calculated in the resistance equation. Refer to the table below.

The CEN-TVAV may be programmed through the host control system or directly via 
the local RS-232 port. To program the CN-TVAV at the RS-232 port, a modular 
cable, an RJ11 to DB9F adapter and 6-conductor modular cable are required. These 
components are not supplied but are part of the SmarTouch Programming Kit 
(ST-PK). If available, use these components. 

When programming, refer to the figure on the next page for a typical connection 
diagram. Complete the following steps in the order provided to ensure proper 
connection.  

WARNING:  When the POWER IN cord is plugged into an energized outlet, 
POWER OUT becomes energized. Crestron recommends connecting the TV or AV 
device before plugging the POWER IN cord into an outlet. 

NOTE:  The following procedure assumes that a touchpanel is being used as the 
user interface. If a wireless hand-held transmitter is utilized, no connections to a user 
interface need to be made.
