CNX Enhanced Ethernet
Expansion Card: CNXENET+
Description
Functional Description
The CNX Enhanced Ethernet Expansion Card, CNXENET+, is an optional feature
designed specifically for Crestron’s CNMSX and CNRACKX control systems. This
field-upgradable expansion card connects directly to Crestron’s exclusive Direct
Processor Access (DPA) slot providing high-speed access directly to the system
processor. The CNXENET+ provides communication via Ethernet/local area
network (LAN) and wide area network (WAN) to any Crestron Internet protocol (IP)
control device. This allows remote diagnostics and upgrades, access to Crestron’s
network analyzer, and the ability to activate any device connected to the system.
As part of Crestron e-Control™, the CNXENET+ allows Internet connections to the
control system. The CNXENET+ contains a 2Mbyte file system that can be used as a
web server. Browser pages generated in VisionTools™ Pro-e (VT Pro-e) are stored
onboard and up to five users can simultaneously connect directly to the control
system. Systems can be accessed through the World Wide Web using industry
browsers such as Microsoft® Internet Explorer™ or Netscape® Navigator. For a
Crestron e-Control demonstration, go to www.crestron-econtrol.com.
Further information and additional Crestron e-Control software can be obtained from
the What’s New page (e-Control section) or Downloads page (ECONTROL Library)
of Crestron’s website (www.crestron.com). New users are required to register in
order to obtain access to the FTP site.
Physical Description
The CNXENET+, shown on the next page, is an expansion card that occupies the
DPA slot and connects directly to the control system’s processor. There are two

Crestron CNXENET+ CNX Enhanced Ethernet Expansion Card
Programming with SIMPL Windows
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'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.
The next two sections describe a CNXENET+ within a SIMPL Windows program.
The first section provides initial configuration information and the second section
details the TCP/IP Server and TCP/IP Client symbols in SIMPL Windows. There is
no symbol required for the CNXENET+.
NOTE: The following descriptions assume that the reader has knowledge of SIMPL
Windows. If not, refer to the extensive help information provided with the software.
NOTE: VisionTools™ Pro-e (VT Pro-e) is a Windows compatible software
package for creating Crestron touchpanel screen designs. Version 2.1.8 or later of
VT Pro-e is required to produce the CNXENET+ example touchpanel pages. The
latest version of VT Pro-e can be obtained from the What’s New page (VisionTools
Pro-e section) or Downloads page (TOUCHPNL Library) of Crestron’s website
(www.crestron.com).
NOTE: An example SIMPL Windows program is available from the Downloads
page (EXAMPLES Library) of Crestron’s website (www.crestron.com). Search for
CNXENET.ZIP. It contains SIMPL Windows file(s), touchpanel pages (if
applicable) and any associated macros required for the example. As Crestron
improves functions, adds new features, and extends the capabilities of the
CNXENET+, additional example programs may be posted to the library. Future
example files shall carry the same filenames plus a numeric (i.e., CNXENET1.ZIP).
Check for any future updates.
Configure CNXENET+ Program
To create a program with a CNXENET+, in the Configuration Manager of SIMPL
Windows, refer to the table on the next page for initial configuration information.
In the Configuration Manager in SIMPL Windows, the CNXENET+ can use all
symbols that are available for the standard CNXENET including virtual
communications port, e-Control PC interface, and active CNX interface. The
CNXENET+ also uses TCP/IP Server and the TCP/IP Client symbols (not available
on the standard CNXENET card). The TCP/IP Server and the TCP/IP Client symbols
are dropped onto the CNXENET+ card as devices. They each have an IP ID and an
associated entry in the IP Table.

CHANGE IP ID (OPTIONAL) -
Double-click on TCP/IP Server
or TCP/IP Client (or single-click
then right mouse-click). Select
Configure. Select IP ID then
select desired hexidecimal ID.
The server symbol “listens” for a connection on a particular socket, and a client
symbol is capable of connecting or disconnecting a socket. A socket is comprised of
an IP Address and a Port Number. The IP Address is specified in the IP Table on the
IP ID that the symbol is on. The Port number is specified in the symbol. For
example, if the server symbol is dropped on IP ID 15, and the IP Table entry for IP
ID 15 is 192.168.1.1, the server will listen for a connection on a 192.168.1.1 on the
port number specified in the symbol.
In typical TCP/IP Terminology, a client connects to a server. In this case, the server
symbol can handle only one connection to it. Since the sockets are generic TCP/IP,
the client can connect to any server (Crestron's TCP/IP Server symbol or any non-
Crestron server) and the server can accept a connection from any client (Crestron's
TCP/IP Client symbol or any non-Crestron client).
TCP/IP Server and TCP/IP Client Symbols
The diagrams below and on the next page show the TCP/IP Server and the TCP/IP
Client symbols in SIMPL Windows. The table that follows each diagram lists the
inputs, outputs, and parameters, respectively, and their functional descriptions.
NOTE: TCP/IP Server and the TCP/IP Client symbols are available for the
CNXENT+ card only and cannot be used with the standard CNXENET card.
NOTE: All digital signals listed in the following tables can be high (logic level of
1), low (logic level of 0), and also have rising edge (when it goes from low to high)
and falling edge (from high to low) transitions. Depending upon how the symbol was
created, symbol inputs may work at the logic levels, some may work on transitions.

Control System Ethernet Setup
This section explains how to configure a control system to communicate over
Ethernet using standard IP. These procedures assume that the CNXENET+ has been
physically installed, added to the control system through SIMPL Windows, and the
control system has been powered up.
Operations & Installation Guide – DOC. 8153A CNX Enhanced Ethernet Expansion Card: CNXENET+ •11

CNX Enhanced Ethernet Expansion Card Crestron CNXENET+
Initial IP Setup
NOTE: This initial IP setup MUST be done via the RS-232 COMPUTER port.
Before performing this procedure, obtain a straight-through RS-232 cable that has a
DB9 male connector on one end and a DB9 female connector on the other. Straight-
through means that pin-1 on the male end is connected to pin-1 on the female end,
etc. The male end plugs into the control system port labeled COMPUTER. The
female end plugs into the serial port of a PC. If the PC has a DB25 male connector,
obtain a DB9 to DB25 adapter (the adapter has a DB9 male end and a DB25 female
end). Thereafter, communications may be achieved by using the Crestron Viewport
to directly connect to the IP address assigned to the control system.
NOTE: It is assumed that the user has communications with the control system and
the appropriate Upgrade file has been loaded. See the CNMSX-AV/PRO or
CNRACKX/-DP Operations Guide sections “Obtaining Communications” and
“Using a Control System Upgrade file” for further details.

6. You will receive a confirmation message that the control system IP
information has been setup. After the system reboots, select Function |
Cold Boot, to view the IP Information.
NOTE: If an error that the Viewport could not setup the IP information opens, first
verify that the CNXENET+ card is installed and seated properly. Second, verify that
the control system has been updated to the minimum operating system (refer to
“Leading Specifications” on page 2) required for Ethernet functionality. If the
control system still cannot set the IP information, contact Crestron customer service.
IP Table Setup
NOTE: To add Ethernet capability to a SIMPL Windows program using a CNMSX-
AV/PRO or CNRACKX/-DP, select a CNXENET+ card from the "Plug-In DPA
Modules" category and drop it onto the DPA card slot.
Ethernet devices that are addressed by the control system may have their IP IDs set
either in the SIMPL Windows program or through the Viewport using a PC. Just as
each Cresnet device is assigned a Cresnet identification (NET ID), e.g. 03 through
FE, to be used when programming, an Ethernet device is assigned an IP ID which
also may range from 03 through FE. Ultimately, each IP ID is converted into an
actual IP address through an IP table that exists inside the control system.

Crestron CNXENET+ CNX Enhanced Ethernet Expansion Card
Adding Devices and IP Table Setup in SIMPL Windows
To add Ethernet devices to your program, in the SIMPL Windows' Configuration
Manager, drag an Ethernet-connected device, e.g. a CEN-IO or a Virtual Touchpanel
symbol, into the program. Drop it onto the CNXENET+ card or the "Ethernet Units"
arrow underneath the "Cresnet Units" arrow. (If the "Cresnet Units" arrow is not
visible in the System View window, pull the window divider down further.)
1. Double click on the icon and set an IP ID and a corresponding IP
address in the tabbed configuration dialog titled "IP Net Address".
2. For example, drop a CEN-IO and set it IP ID: 03 at IP address
192.168.2.7 OR in the SIMPL Windows Program Manager, connect
signals to the "Virtual Touchpanel" symbol, exactly as you would to a
regular wired Touchpanel symbol.
NOTE: For more detailed information, refer to the SIMPL Windows help file by
selecting Help | Help Topics. Select the Index tab, type in IP Table, then select
Adding Ethernet Devices to a SIMPL Windows Program.
When the SIMPL Windows program is compiled, the compiler creates an IP table
consisting of the IP IDs and the IP addresses that were entered for the various
Ethernet devices added to the program. During upload, choose whether to load this
IP table or whether to use the table that already exists in the control system.
Changing the IP Table via Crestron Viewport
You can modify the corresponding IP address for any IP ID without changing or
reloading the program by changing the IP table directly. From the Crestron Viewport
select Functions | Setup IP Table then click the Retrieve Current IP Table from
Control System button. This will extract the IP table from the control system and
list it in the dialog box. Modify or delete existing entries or add new ones and save
the new table to disk and/or load it back into the control system. Do not overwrite the
IP table in the control system the next time the program is uploaded, unless the
addresses in the program supercede those in the current IP table.
NOTE: For more detailed information, refer to the SIMPL Windows help file by
selecting Help |Help Topics. Select the Index tab, type in IP table, then select
Changing IP Addresses without Changing the Program.
Crestron e-Control IP Table Information
It is extremely important that the IP ID in the SIMPL Windows program match the
IP ID (sometimes called the Cres ID) encoded in the Crestron e-Control SDK object
by the developer of the Web page or Visual Basic® program.
If more than one PC uses the same IP ID for a connection (e.g. each loads the same
Web page), the CNX Gateway will duplicate all packets that are received from the
control system to each of the identical IP IDs. This is known as touchpanel tracking.
The IP address that is typed into the virtual touchpanel devices in the SIMPL
Windows program is the IP address of the CNX Gateway, not of the individual PCs
(running a web browser or Active CNX application). This is because individual
computers may change, but the CNX Gateway does not.
