Earliest Version Software Requirements for the PC
NOTE: Crestron recommends that you use the latest software to take
advantage of the most recently released features. The latest software is
available from the Crestron website.
Crestron has developed an assortment of Windows®-based software tools
to develop a Cresnet system. You can create a program to control the
DIN-8SW8 using the Crestron programming tools Crestron
SystemBuilder, D3 Pro™ or SIMPL Windows. Customers whose focus is
on lighting systems may prefer to use the D3 Pro software since it is
designed especially for creating lighting and environmental system
control applications. Customers already familiar with SIMPL Windows
who are including a lighting system as part of an overall control system
project may prefer to continue using SIMPL Windows. For the minimum
recommended software versions, visit the Version Tracker page of the
Crestron website (
www.crestron.com/versiontracker).
Programming with Crestron SystemBuilder
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.
Operations & Installation Guide – DOC. 6666A DIN Rail High-Voltage Switch: DIN-8SW8 • 15
Page 20
DIN Rail High-Voltage Switch Crestron DIN-8SW8
Programming with D3 Pro
Crestron’s D3 Pro lighting software provides all the tools necessary to
create a complete Crestron lighting system for residential applications.
The lighting system includes the control system logic program,
touchpanel projects and keypad programming, documentation and realtime lighting adjustment capabilities.
As with all Crestron software, D3 Pro provides extensive right-click and
drag-and-drop functionality in addition to convenient keyboard shortcuts
for frequently used functions and commands.
Programming is organized into six system Views of the lighting system,
each providing a moveable toolbox of devices such as interfaces, fixtures
and control modules. You can add a device to your system simply by
selecting it from one of the toolboxes and dragging it to a room. The
available toolboxes differ depending on the View but all Views include a
"General" toolbox that allows you to add areas and rooms at any time.
Configuration
Manager
Programming with SIMPL Windows
NOTE: While SIMPL Windows can be used to program the
DIN-8SW8, 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 DIM-8SW8into the system, drag the
DIN-8SW8 from the Lighting | Lighting (Din-Rail Series) folder of
the Device Library and drop it in the System Views.

Uploading and Upgrading
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. Once communication
has been established, files (for example, programs or firmware) can be
transferred to the control system (and/or device). Finally, program checks
can be performed (such as changing the device ID or creating an IP table)
to ensure proper functioning.
Establishing Communication
Use Crestron Toolbox for communicating with the DIN-8SW8; refer to
the Crestron Toolbox help file for details. There is a single method of

Check Network Wiring
Use the Right
Wire
Calculate
Power
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 (
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
L <
Where:
40,000
R x P
L = Length of run (or chain) in feet
R = 6 Ohms (Crestron Certif ied Wire: 0.75 MM (18 AWG))
P = Cresnet power usage of entire run (or chain)
2
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 0.75 mm
2
(18 AWG) Crestron Certified Wire and drawing 20 watts should not have
a length of run more than 101 meters (333 feet). Cresnet HP cannot be
used.

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.
Strip and Tin
Wire
Add Hubs
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.
Use of a Cresnet hub/repeater (DIN-HUB) is advised whenever the
number of Cresnet devices on a network exceeds 20 or when the
combined total length of Cresnet cable exceeds 914 meters (3000 feet).
