Integrated Control System:
CNMSX
Description
Functional Description
The CNMSX is an integral part of Crestron’s new generation of control system
technology featuring the newest series of Ethernet/local area network (LAN)
compatible control systems. The CNMSX is an integrated control system with eight
infrared (IR)/serial ports, six bidirectional RS-232/422/485 ports, eight digital/analog
input and digital output ports, eight isolated relays, and an integrated 110/220 VAC
(75W) power supply.
Expansion Slots
There is also room for growth; the unit (depending on configuration) offers four
expansion slots. One of the slots features Crestron’s exclusive Direct Processor
Access (DPA) port for Ethernet/LAN expansion of the control network. This port
provides high-speed access directly to the processor while maintaining bandwidth
network connections. The DPA currently supports the CNXENET (& CNXENET+)
10 BaseT Ethernet cards with future support for Firewire, ATM, 100BaseT, and
popular interfaces. The other three card slots offer system expansion with a variety of
plug-in cards.
LCD Display (available on CNMSX-PRO only)
An 80-character (two 40-character lines) liquid crystal display (LCD) display and an
extended bank of LED indicators are located on the front panel to provide extended
features, status information, and troubleshooting indications.
Configuration Differences
There are two CNMSX configurations available: the PRO and AV. The PRO is the
flagship product in Crestron’s new generation of control systems. It is the model that
has all the features mentioned in the previous section. The AV is a cost-competitive
alternative to the PRO. The AV has all the features of the PRO, except for the
extended bank of status and activity LEDs, front panel LCD screen, and the network
analyzer feature. A “card cage” (CNXCAGE) providing three expansion slots is

4The program size restriction of 100K with the CNXENET card exists if the control system has
the CNXENET installed and a valid IP address is assigned. SIMPL Windows limits the size of
the compiled file to 100K only if the CNXENET has been dropped onto the DPA Card slot.
Typically, if the CNXENET is being used for remote maintenance and not for programming
Ethernet devices (such as e-control touchpanels, etc), most users do not drop the CNXENET
into the program in SIMPL Windows. Please note that the maximum program size is still 100K,
even though SIMPL Windows states 256K during a compile. To make SIMPL Windows enforce
the restriction, drop a CNXENET into the DPA Card slot.

NOTE: This device complies with part 15 of the FCC rules. Operation is subject to the
following two conditions: (1) this device may not cause harmful interference, and (2)
this device must accept any interference received, including interference that may cause
undesired operation.
Setup
Rack Mounting
WARNING: To prevent bodily injury when mounting or servicing this unit in a
rack, take special precautions to ensure that the system remains stable. The following
guidelines are provided to ensure your safety:
 The unit should be mounted at the bottom of the rack if it is the only unit in the
rack.
 When mounting this unit in a partially filled rack, load the rack from the bottom
to the top with the heaviest component at the bottom of the rack.
 If the rack is provided with stabilizing devices, install the stabilizers before
mounting or servicing the unit in the rack.
NOTE: If rack mounting is not required, rubber feet are provided for table-top
mounting or stacking. Apply the feet near the corner edges on the underside of the
unit.
NOTE: Reliable earthing of rack mounted equipment should be maintained.
Particular attention should be given to supply connections other than direct
connections to the branch circuit. (e.g., use of power strips).
Two “ears” are provided with the CNMSX so that the unit can be rack mounted.
These ears must be installed prior to mounting. Complete the procedure below to
attach ears to CNMSX. The only tool required is a #2 Phillips screwdriver.
1. There are 12 screws (#6-32 x 0.375" LG) that secure the sides of the
CNMSX top cover. Using a #2 Phillips screwdriver, remove the three
screws closest to the front panel from one side of the unit.
2. Position a rack ear so that its mounting holes align with the holes
vacated by the screws in step 1.
3. Secure the ear to the CNMSX with three screws from step 1, as shown
on the next page.

4. Repeat procedure (steps 1 through 3) to attach remaining ear to opposite
side.
Bussing Strip Installation
The CNMSX is supplied with a brass bussing strip to facilitate commoning (linking)
of multiple terminal block connections. The bussing strip is constructed with eight
terminal block position, and may be trimmed to size for various applications or
different devices. One strip is supplied for each 16-position terminal block.
1. To utilize the bussing strip, determine the number of relays to be
commoned for the equipment being installed. If less than eight, the strip
can be trimmed to size with a pair of scissors or wire snips.
2. Loosen the terminal block screws and insert the first leg of the bussing
strip into the first common position on the terminal block. The strip
engages the other common positions automatically.
3. Remove approximately 1/8" of the jacket from the common wire and
insert the conductor into one of the terminal block common positions.
Tightenthe terminal block screws to lock the wire and bussing strip into
place. Insulate the strip by folding a piece of ¾" wide vinyl electrical
tape (such as Scotch 33+) over the spine and as much of the individual
legs as possible. Excess tape at each end of the strip should be pressed
closed, then trimmed to within approximately 1/16" of the end of the
strip.
4. When wiring the remaining conductors, remove approximately 1/8" of
the jacket and insert the wires into the proper terminal block positions.
To prevent the possibility of electrical shorts, it is essential that these
conductors do not touch any uninsulated portion of the bussing strip.
5. Securing a tie wrap around the bussing strip is a useful way to strain
relieve the wires connected to the terminal block.
Network Wiring
When calculating the wire gauge for a particular network run, the length of the run
and the power 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 power factor of
each network unit to be daisy-chained must be added together to determine the power
factor of the entire chain. The length of the run in feet and the power factor of the run
should be used in the following resistance equation to calculate the value on the right
side of the equation.

NOTE: All network 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.
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.
Four-Pin Network Connector
For four-pin network cable connections in a Crestron remote control system, the
Cresnet cable is used to power Crestron devices. Before making any four-pin network
connections to the CNMSX, refer to the network interconnection after this paragraph.

NOTE: To prevent overheating, do not operate this product in an area that exceeds
the recommended ambient temperature of 104°F (40°C). Consideration must be
given if installed in a closed or multi-unit rack assembly since the operating ambient
temperature of the rack environment may be greater than the room ambient. Contact
with thermal insulating materials should be avoided on all sides of the unit.
NOTE: The maximum continuous current from equipment under any external load
conditions shall not exceed a current limit that is suitable for the minimum wire gauge
used in interconnecting cables. The ratings on the connecting unit's supply input
should be considered to prevent overloading the wiring.
NOTE: Since the plug on the power supply cord is used to disconnect power from
the unit, the socket-outlet shall be installed near the equipment and shall be easily
accessible.

Programming the LCD Display (available on CNMSX-PRO
only)
NOTE: The following description assumes that the reader has some knowledge of
SIMPL™ Windows®. If not, please refer to the extensive help information provided
with the software.
SIMPL (Symbol Intensive Master Programming Language) is an easy-to-use
programming language that is completely integrated and compatible with all Crestron
system hardware. The objects that are used in SIMPL are called symbols. SIMPL
Windows offers drag and drop functionality in a familiar Windows® environment.
SIMPL Windows is Crestron Electronics development environment 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.
The CNMSX-PRO LCD display is preprogrammed with a certain level of diagnostic,
testing, and network device information. Assuming the CNMSX is connected to a PC
running SIMPL Windows, a LCD display programming utility (Front Panel Editor)
can be accessed. This editor enables a programmer to program multi-level pages
under the PANEL (left-most, function) button on the LCD display.
Front Panel Editor
The LCD display on a CNMSX-PRO has different pages that are defined by the
programmer. Menu function buttons are assigned to different pages or objects. The
LCD display has a 2x40 character display with six-programmable buttons.
In Front Panel Editor, pages are designed and added to the panel. An example of the
default page is shown after this paragraph. Each front page is one display (2x40
characters) and can have as many objects as the physical size of the display allows
(objects can not overlap). The top line of the panel is used for informative object
displays, such as headings, indirect text, bar graphs, and time/date displays. The
bottom line of the panel is for objects that are accessed by the six menu function
buttons below the display. The buttons only access the page or object whose field is
directly over the button. Objects added to the bottom line of the display can have page

jumps or logic programming in SIMPL Windows that cause specific events to occur.
These objects are initiated by pressing the function button that is associated with it.

Creating a Page with Front Panel Editor
NOTE: The creation of a front panel page is discussed in this section. For more
details, consult the SIMPL Windows help file. Search for Front Panel Editor.
Assume that a page, as shown below, is required. The concept of such an application
is that the user can then choose a given device and then, from a lower-level page,
control one or more transport functions of the device.
Example of a Front Panel Page
Adding Top-Level Pages and Objects
Use SIMPL Windows and access the Front Panel Editor by selecting Project | Edit
Front Panel. Click on the Add button and enter a new name for the new page. For
this example, use “Menu1 – Choose Device” as the name.
Double click inside the display area of the front panel on the screen to open the “Edit
Panel Object” dialog box. This example requires that headings be added to the page,
so choose Text Object from the Object Type area. In the Inactive Text field, enter
“Choose device”. The object is displayed on the panel. Click on and drag the object to
its desired location on the panel, top row.
Add additional objects (VCR, LaserDisc, CD, Lights, and Volume) to the page by
double clicking in the display area where the object is to appear. Repeat the procedure
in the previous paragraph; place objects over the appropriate menu function button.
Adding Lower-Level Pages and Objects
Lower-level pages can be added for each of the objects on the bottom row of the page
just created. For the purposes of this example, one lower-level page is added for the
VCR object. Simply click on the Add button and enter a new name for the new page.
For this example, use “Menu2 – VCR Control” as the name.
Return to the “Menu1 – Choose Device” and double click on the VCR object. The
“Edit Panel Object” dialog box appears. From the Menu Jump field, select “Menu2 –
VCR Control” and click OK. Select the Simulate check box to make the Front Panel
