CAUTION:
To avoid damage to the pins of the plug, do not use excessive force
when seating the keypad into the keypad mounting assembly. When properly
aligned, the 18-pin plug inserts easily into the socket
8.
As shown below, insert the keypad upper-tab into the keypad mounting
assembly upper-slot. Align the keypad 18-pin plug with the assembly
18-pin socket and
gently
push the keypad
inward
until it is fully
seated.

If applicable, re-install the designer or decorator wall-plate onto the
CN-WP12F.
Network Wiring
NOTE:
When making category 5 wire connections, refer to the latest revision of the
Cresnet Mini Network Cat 5 Interconnect Data Sheet (Doc. 5819).
When calculating the wire gauge for a particular network run, the length of the run
and the load factor of each network unit to be connected must be taken into
consideration. If network units are to be daisy-chained on the run, the load factor of
each network unit to be daisy-chained must be added together to determine the load
factor of the entire chain. If the network unit is a home-run from a Crestron system
power supply network port, the load factor of that network 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.
Resistance Equation
R = Resistance (refer to next table).
L = Length of run (or chain) in feet.
LF = Load factor of entire run (or chain).
R <
L x L F
4 0 ,000
W h e r e :
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 on the next page:
