Crestron SystemBuilder is the easiest method of programming, but does
not offer as much flexibility as SIMPL Windows. For additional details,
download SystemBuilder from the Crestron website and examine the
extensive help file.
Programming with SIMPL Windows
NOTE: While SIMPL Windows can be used to program the
C2N-DBF/N12, it is recommended to use SystemBuilder for configuring
a system.
SIMPL Windows is Crestron’s premier software for programming
Crestron control systems. It is organized into two separate, but equally
important “Managers”.
Configuration Manager is the view where programmers “build” a
Crestron control system by selecting hardware from the Device Library.
• To incorporate the C2N-DBF/N12 into the system, drag the
C2N-DBF/N12 from the Wired Keypad folder of the Device Library and drop it in the System Views.

• Additional C2N-DBF12 & C2N-DBN12 devices are assigned
different Net ID numbers as they are added.
• If necessary, double click a device to open the “Device Settings”
window and change the Net ID, as shown in the following figure.
• The ID code specified in the SIMPL Windows program must
match the Net ID of each unit.
Programming
Manager
Programming Manager is the view where programmers “program” a
Crestron control system by assigning signals to symbols. The symbol can
be viewed by double clicking on the icon or dragging it into Detail View.
Each signal in the symbol is described in the SIMPL Windows help file
(F1).
Crestron recommends using the latest programming software and that
each device contains the latest firmware to take advantage of the most
recently released features. However, before attempting to upload or
upgrade, it is necessary to establish communication.
Establishing Communication
Use Crestron Toolbox for communicating with the C2N-DBF/N12; refer
to the Crestron Toolbox help file for details. There is a single method of
communication: indirect serial communication.

The C2N-DBN12 can be used to expand the capabilities of the source
keypad and is ideal for audio device functions such as selecting a
particular CD track number or a certain CD from a CD changer.
All buttons on the keypad are functionally identical and have light
emitting diodes (LEDs) that serve as user feedback indicators. Each
LED’s illumination (on/off) is independently addressable and is
programmable using SIMPL Windows.
In the program, the intensity level for all of the button LEDs can be set
from 0 to 100%.
The table below provides corrective action for possible trouble situations.

In order to ensure optimum performance over the full range of your
installation topology, Crestron Certified Wire, and only Crestron
Certified Wire, may be used. Failure to do so may incur additional
charges if support is required to identify performance deficiencies
because of using improper wire.
CAUTION: Use only Crestron power supplies for Crestron equipment.
Failure to do so could cause equipment damage or void the Crestron
warranty.
CAUTION: Provide sufficient power to the system. Insufficient power
can lead to unpredictable results or damage to the equipment. Please use
the Crestron Power Calculator to help calculate how much power is
needed for the system (http://www.crestron.com/calculators
When calculating the length of wire for a particular Cresnet run, the wire
gauge and the Cresnet power usage of each network unit to be connected
must be taken into consideration. Use Crestron Certified Wire only. If
Cresnet units are to be daisy-chained on the run, the Cresnet power usage
of each network unit to be daisy-chained must be added together to
determine the Cresnet power usage of the entire chain. If the unit is
home-run from a Crestron system power supply network port, the
Cresnet power usage of that unit is the Cresnet power usage of the entire
run. The wire gauge and the Cresnet power usage of the run should be
used in the following equation to calculate the cable length value on the
equation’s left side.
Cable Length Equation
Strip and Tin
Wire
L = Length of run (or chain) in feet
R = 6 Ohms (Crestron Certified Wire: 18 AWG (0.75 MM ))
or 1.6 Ohms (Cresnet HP: 12 AWG (4 MM ))
P = Cresnet power usage of entire run (or chain)
2
2
L <
40,000
Where:
R x P
Make sure the cable length value is less than the value calculated on the
right side of the equation. For example, a Cresnet run using 18 AWG
Crestron Certified Wire and drawing 20 watts should not have a length of
run more than 333 feet. If Cresnet HP is used for the same run, its length
could extend to 1250 feet.
NOTE: All Crestron certified Cresnet wiring must consist of two
twisted pairs. One twisted pair is the +24V conductor and the GND
conductor, and the other twisted pair is the Y conductor and the Z
conductor.
When daisy-chaining Cresnet units, strip the ends of the wires carefully
to avoid nicking the conductors. Twist together the ends of the wires that
share a pin on the network connector, and tin the twisted connection.
Apply solder only to the ends of the twisted wires. Avoid tinning too far
up the wires or the end becomes brittle. Insert the tinned connection into
the Cresnet connector and tighten the retaining screw. Repeat the
procedure for the other three conductors.
Add Hubs
For larger networks (i.e., greater than 28 network devices), it may
become necessary to add a Cresnet Hub/Repeater (CNXHUB) to
maintain signal quality throughout the network. Also, for networks with
lengthy cable runs, it may be necessary to add a Hub/Repeater after only
20 devices.
