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-2MC2 using the Crestron programming tools Crestron
SystemBuilder™, D3 Pro
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

®

or SIMPL Windows. Customers whose focus

).

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.

14 • DIN Rail Motor Control: DIN-2MC2 Operations & Installation Guide – DOC. 6665B

Crestron DIN-2MC2 DIN Rail Motor Control

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-2MC2, 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.

1. To incorporate the DIN-2MC2 into the system, drag the

DIN-2MC2 from the Lighting | Lighting (DIN-Rail Series) folder

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-2MC2; refer to
the Crestron Toolbox help file for details. There is a single method of
communication: indirect communication.

Operation

NET ID

Manual
Control

Use the NET ID buttons to change the Net ID of the DIN-2MC2. For
more information on setting the Net ID, refer to “Identity Code” on
page 9.

Each of the DIN-2MC2 outputs can be in one of three states: OPEN,
CLOSE, or STOP. When an output is in the OPEN state, the OPEN LED
illuminates. When an output is in the CLOSE state, the CLOSE LED
illuminates. When an output is in the STOP state, neither of the output
LEDs illuminate.

The state of each output can be manually controlled from the buttons on
the front panel.

If an output is in the STOP state, press and release the OPEN or CLOSE
button to activate the OPEN or CLOSE state. The corresponding LED
illuminates to indicate the state of the output. The LED stays lit until the
programmable “max time” parameter is reached. Additionally, the NET
ID display briefly indicates the state of the output (“OP” for open, “CL”
for close).

If an output is in the OPEN or CLOSE state, pressing the OPEN or
CLOSE button places the output in the STOP state. Neither of the LEDs
illuminate. However, the NET ID display briefly indicates the state of
the output (“St” for stop).

An output left in the OPEN or CLOSE state reverts to the STOP state
after a programmable timeout.

NOTE: The control system program may change the state of the output
if the Override mode is not enabled.

Override
Mode

20 • DIN Rail Motor Control: DIN-2MC2 Operations & Installation Guide – DOC. 6665B

The Override mode overrides the control system program and sets the
motor outputs to the saved override settings. For instructions on saving
override settings, refer to “Save Override Settings” on page 21.

To enable the Override mode, press and release the OVR button. The

OVR LED flashes slowly.

NOTE: If the Override mode was enabled from an external device (i.e.,

a contact closure is present on the OVERRIDE terminals), the OVR
LED flashes quickly. Pressing the OVR button has no effect.

Crestron DIN-2MC2 DIN Rail Motor Control

To disable the Override mode, press the OVR button again. The OVR
LED extinguishes and the motor outputs go to their STOP states.

NOTE: If override settings have not been saved, the factory default
setting is for the motor outputs to remain unaffected when the Override
mode is enabled.

Save
Override
Settings

The state of each output can be saved as an override setting which can be
automatically recalled when the Override mode is enabled.

NOTE: The control system program has a setting that can prevent
locally saving the override settings. If this setting is enabled, the display
shows “Er” when trying to save the override settings. For more
information, refer to the SIMPL Windows help file.

To save the state of an output as an override setting:

1. Press the OPEN or CLOSE control button to activate the desired

function on one or both motor outputs. To leave an output
unaffected by the Override mode, leave the output in the STOP
state.

2. Press and hold the OVR button for three seconds. The OVR LED

blinks to indicate new override settings have been stored. Motor
outputs that were “closing” are set to go to the “Full Close”
position when the Override mode is enabled. Motor outputs that
were “opening” are set to go to the “Full Open” position when the
Override mode is enabled. Motor outputs that were “stopped” are
unaffected when the Override mode is enabled.

Reset

To reboot the DIN-2MC2, press the RESET button. The motor outputs
are set to the state currently specified by the control system program. If
the control system does not provide a setting, the outputs are set to the
last-known state.

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

Strip and Tin
Wire

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 wire 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.

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

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).
