Crestron C2N-MMS Professional Multimedia Switch
Professional Multimedia Switch:
C2N-MMS
Introduction
Features and Functions
The Crestron®Professional Multimedia Switch C2N-MMS is a high performance
multimedia switch that can switch four RGB sources to two RGB devices and three
video sources to two video devices. With the optional C2N-MMS-SC scan converter
card, the RGB sources can also be switched to the video devices. The C2N-MMS
features three Y/C (S-video)/composite inputs, four RGB inputs, two Y/C
(S-video)/composite outputs, and two RGB outputs.
C2N-MMS Functional Summary
• Four RGB input channels with selectable sync impedance* and Auto-
Detect
• Two RGB output channels with user-selectable frequency and level
compensation for longer cable runs
• Three video input channels with Auto-Detect supporting composite and
Y/C (S-video) formats
• Two video output channels supporting composite and Y/C (S-video)
formats
• Supports NTSC and PAL signal types
• Transient blanking on RGB input signals to avoid visible transients
when switching between RGB sources
• 400 MHz bandwidth for RGB signals, 100 MHz bandwidth for video
signals
• Optional scan converter card C2N-MMS-SC allows RGB signals to be
switched to video output devices
* Selectable sync impedance is only available on C2N-MMS devices with the part number 6003312 on
the manufacturing label located on the bottom of the unit. Units labeled with 6001581 do not have
this feature.
The C2N-MMS can drive RGB cable runs over 100 feet with user-selectable

coax cables of longer lengths (50 to 100 feet). The C2N-MMS automatically detects
the presence of video and RGB signals by monitoring activity on the luminance
(COMP/Y) connection of each video input and the horizontal sync line of each RGB
input. For laptops that require the presence of a monitor to enable its video output,
the C2N-MMS has a selectable feature (DDC) that simulates the presence of a
generic high-resolution monitor so RGB sources (such as a laptop computer) will
transmit a signal even when a RGB device is not connected to the C2N-MMS output.
NOTE: Selectable sync impedance and the DDC feature are only available on
C2N-MMS devices with the part number 6003312 on the manufacturing label
located on the bottom of the unit. Units labeled with part number 6001581 do not
have this feature.
RGB signal switching features transient blanking to avoid visible transients when
switching between RGB sources operating at different sync frequencies. Transient
blanking disables the output signal before the sync is switched to another source.
Transient-free switching between RGB sources is completed in less than 1/10 of a
second.

 Consult the dealer or an experienced radio/TV technician for help.
Setup
Network Wiring
CAUTION: 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 as a result 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 a 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
40,000 Where:
R x P
L <
L = Length of run (or chain) in feet.
R = 6 Ohms (Crestron Certified Wire: 18 AWG (0.75 MM2))
P = Cresnet power usage of entire run (or chain).
Make sure the cable length value is less than the value calculated on the right side of
the equation. For example, a Cresnet run drawing 20 watts should not have a length
of run more than 333 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.
8 •Professional Multimedia Switch: C2N-MMS Operations Guide – DOC. 6374

Crestron C2N-MMS Professional Multimedia Switch
NOTE: 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.
NOTE: 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.
Crestron Toolbox
NOTE: The minimum version of Crestron Toolbox required to operate with the
C2N-MMS is version 1.0.06 or later.
The Crestron Toolbox (a replacement for Crestron Viewport, you may continue to
use Viewport version 3.109 or later if desired) is a broad-based software package
that accomplishes multiple system tasks, primarily using an RS-232 or TCP/IP
connection between a PC and one or more Crestron control systems.
You can use the Crestron Toolbox to:
• Observe system processes.
• Upload operating systems and firmware.
• Upload programs and touchpanel projects.
• Set or change device Network IDs.
• Change serial numbers.
• Run scripts to automate tasks.
• Perform system diagnostics, and much more.
The Crestron Toolbox allows you to perform these functions using simple graphical
views and click and drag methods.
Identity Code
Every network device and user interface within the Cresnet network requires a
unique identity code (Net ID). These codes are two-digit hexadecimal numbers from
03 to FE. The Net ID of each unit must match an ID code specified in the SIMPL
Windows program. Refer to “Setting the Net ID in Device Settings” on page 18 for
details of the SIMPL Windows procedure.
The Net ID of the C2N-MMS has been factory set to 11. The Net IDs of multiple
C2N-MMS devices in the same system must be unique. Net IDs are changed from a
personal computer (PC) via the Crestron Toolbox.
NOTE: For detailed information on establishing communication between the PC,
control system, and the C2N-MMS, refer to “Establishing Communications” on page
19. If communication cannot be established, refer to the “Troubleshooting
Communications” section in the latest version of the 2-Series Control System
Reference Guide (Doc. 6256), which is available from the Crestron website.
Operations Guide – DOC. 6374 Professional Multimedia Switch: C2N-MMS •9

Professional Multimedia Switch Crestron C2N-MMS
The Crestron Toolbox provides several methods to easily set or change device Net
IDs for any device on the network. The following method permits you to change the
Net ID of any device in the network through the “Network Device Tree” window.
NOTE: This method prevents you from selecting an existing Net ID that is assigned
to a device that is not equipped with TSID.
This method permits you to manually set the Net ID for any device in the network,
set any known Net IDs that may require changing, and may also be used for non-
TSID equipment. This method will not permit you to choose an ID already in use by
another device that is not equipped with TSID. A warning message will appear if you
attempt to use an ID that is already in use by a device that is equipped with TSID.
Duplicate Net ID Warning Message
This method does not change the Net ID as assigned in SIMPL Windows. For
information on setting the Net ID in SIMPL Windows, refer to “Setting the Net ID in
Device Settings” on page 18.
NOTE: You may also use SystemBuilder™ to perform Network ID setup. Refer to
the respective help file for more information.

Configuring the RGB Input Ports
Each of the four RGB input ports feature a set of six DIP switches located inside the
C2N-MMS. These switches are used to configure the sync input impedance of each
port and enable the DDC feature of each RGB input.
NOTE: DIP switches for selecting input impedance and the DDC feature are only
available on C2N-MMS devices with the part number 6003312 on the manufacturing
label located on the bottom of the unit. Units labeled with part number 6001581 do
not have this feature.
Operations Guide – DOC. 6374 Professional Multimedia Switch: C2N-MMS •11

Professional Multimedia Switch Crestron C2N-MMS
The sync input impedance can be set to either 1k, 500, or 75 ohms. The setting from
the factory is 1k ohms and should work with most RGB sources. If the signal quality
is poor, lowering the input impedance to match the impedance of coax cable may
alleviate sync signal problems that are associated with RGB cables greater than the
typical VESA standard (typically six feet).
For laptops that require the presence of a monitor to enable its video output, the
C2N-MMS has a selectable feature (DDC) that simulates the presence of a generic
high-resolution monitor so RGB sources (such as a laptop computer) will transmit a
signal even when a RGB device is not connected to the C2N-MMS output. Changing
a DIP switch setting can enable or disable this feature. The C2N-MMS is shipped
from the factory with the DDC feature disabled.
NOTE: The sync input impedance and DDC feature should be set prior to placing
the C2N-MMS in an equipment rack.
Finding the DIP Switches
The DIP switches that configure the RGB input ports are located inside the
C2N-MMS. The only tools required are a #2 Phillips screwdriver and a grounding
strap (or grounded workstation).
CAUTION: The C2N-MMS contains ESD-sensitive devices. Perform the following
procedure while wearing a grounding strap that is properly grounded or on a
grounded workstation to avoid damaging the C2N-MMS.
1. Make all connections to the C2N-MMS as described in “Hardware
Hookup” on page 11.
2. Open the C2N-MMS by removing the 16 screws (located on the sides and

RGB Signal Compensation
To account for varying cable lengths for RGB output signals, the C2N-MMS features
switchable 3 dB frequency compensation and 1.25 dB signal boost to provide clear
images on cable runs over 100 feet. The following table illustrates which settings to
use for specific RGB cable lengths. All settings are made from the control system
program. Refer to “Programming Software” on page 15 for more information.

Setup is easy thanks to Crestron’s Windows-based programming software.
Crestron’s SystemBuilder software creates a complete project, with no special
programming required. While traditional programming tools can still be used to
program a system, SystemBuilder can be used to easily complete all necessary
programming for a base system including all touchpanel screens and the control
system program. The program output of SystemBuilder is a SIMPL Windows
program with much of the functionality encapsulated in macros and templates. Once
SystemBuilder creates the project, the system interfaces and program logic can be
customized in SystemBuilder or can be easily modified with Crestron development
tools (i.e., SIMPL Windows and Crestron VisionTools®Pro-e (VT Pro-e) software
packages).
NOTE: Modifications to the program that are made outside of SystemBuilder (for
example, in VT Pro-e or SIMPL Windows) are not preserved when you reenter
SystemBuilder.
SystemBuilder comes with templates for all supported interfaces. If a user wishes to
create a touchpanel project using templates with a different look-and-feel, this can be
accomplished by making a custom template. This custom template can then be used
by SystemBuilder to create the final project files to be loaded into the panels.
Alternatively, VT Pro-e can be used to tweak projects created with the
SystemBuilder or develop original touchpanel screen designs.
Digital, analog and serial join numbers are a common thread between VT Pro-e and
SIMPL Windows. These numbers define how the objects on a touchpanel page of a
VT Pro-e project interface to the outside world, specifically the Cresnet system as
defined in the SIMPL Windows program. There are digital join numbers that carry
out some predetermined function (a logical high or low); analog join numbers for
displaying incremental values, sliders, gauges and bar graphs; and serial join
numbers that allow for the display of variable text and transmission/reception of
serial commands from other manufacturers. Unjoined objects are not interfaced with
the system and thus cannot initiate any logic functions (although they can perform
page flips).

Programming with the Crestron SystemBuilder
The easiest method of
p
rogramming, but does not
offer as much flexibility as
SIMPL Windows.
Crestron SystemBuilder offers automatic programming for such residential and
commercial applications as audio distribution, home theater, video conferencing, and
lighting. The interface of this tool guides you through a few basic steps for
designating rooms and specifying the control system, touchpanels, devices, and
functionality. Crestron SystemBuilder then programs the system, including all
touchpanel projects and control system logic.
Crestron SystemBuilder is fully integrated with Crestron's suite of software
development tools, including SIMPL Windows, VT Pro-e, and the Crestron
Database. Crestron SystemBuilder accesses these tools behind the scenes, enabling
you to easily create robust systems.
For additional details, download SystemBuilder from the Crestron website and
examine the extensive help file.
Programming with SIMPL Windows
NOTE: The following assumes that the reader has knowledge of SIMPL Windows.
If not, refer to the extensive help information provided with the software.
NOTE: The following are acceptable file extensions for programs that include a
C2N-MMS, developed for specific control system types:
.smw: projectname.smw (SIMPL Windows source file)
.spz: projectname.spz (compiled file for 2-series)
.usp: projectname.usp (source code module for SIMPL+)
.umc: projectname.umc (user macro for SIMPL)
NOTE: In the following description, the MP2E multimedia processor is used.
SIMPL Windows is Crestron's software for programming Crestron control systems.
It provides a well-designed graphical environment with a number of workspaces
(i.e., windows) in which a programmer can select, configure, program, test, and
monitor a Crestron control system. SIMPL Windows offers drag and drop
functionality in a familiar Windows®environment.
