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)
order to obtain access to the FTP site.

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.

TCP/IP Server or TCP/IP Client
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 non­Crestron 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.

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. Straight­through 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.
1. From the Crestron Viewport, select Functions | Set Control System IP Information, as shown below:

IP Table Setup

NOTE: To add Ethernet capability to a SIMPL Windows program using a CNMSX­AV/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.
14 • CNX Enhanced Ethernet Expansion Card: CNXENET+ Operations & Installation Guide – DOC. 8153A
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.

Troubleshooting Communications via Ethernet

You can PING the control system from a MS-DOS® prompt (Windows 95/98/Me™) or a Command Prompt (Windows NT/2000™). In the example below, the control system is at address 172.16.135.246. When pinged, the unit should reply and there should be no packet loss, as shown below.
MS-DOS or Command Screen
NOTE: The round trip times for a control system plugged into a LAN versus going out over the Internet will vary greatly. If there is a ping reply, communications should work properly via a SIMPL program and via the Viewport. If there is no reply, verify that the IP Settings you have given the control system are correct, and that the PC used to ping the control system can ping other devices that are on the control system's subnet.

Web Pages

To work with CNXENET+ web pages, communication must be established with the control system. To establish communication through the control system COMPUTER port, 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 COMPUTER port. 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 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. To establish Ethernet communication, refer to “Communicating With the Control System via Ethernet” on page 16.

Transferring Web Pages to the CNXENET+

After establishing communication with the control system and verifying communication parameters, use the Viewport (from either SIMPL Windows or VT Pro-e) to transfer web pages designed with VT Pro-e or the e-Control SDK.
1. From Viewport, select File Transfer
Viewport Send Web Pages
NOTE: When the CNXENET+ card receives web page files, it first initializes itself which deletes all of the files on the card. The Crestron Viewport provides 30 seconds before file transfer begins and transferring large web files may exceed this time. When transferring large web files, the card may produce an error of “Can Not Delete Files” or “Transfer Error” in the Viewport. If so, transfer large web files one at a time.

Glossary of Terms

CNX CONTROL SYSTEM
A CNX control system is any Crestron control processor in the CNX product line. Currently, these include the integrated control systems CNMSX-AV and the CNMSX-PRO and modular control systems CNRACKX and the CNRACKX-DP.
CRESNET ID
Cresnet ID, a unique identity code ranging from 03 to FE (in hexadecimal), is given to all devices that communicate using the Cresnet network protocol.
DEFAULT ROUTER
A default router is a router that sends packets within the local network to destinations outside of the local network, or receives them from outside and propagates them onto the local network. It is also referred to as a Gateway.
ETHERNET HUB
Inexpensive four to 16 port devices that provide a way to physically tap into an existing Ethernet connection and expand the plugs available, but do not perform any packet routing.
GATEWAY
See Default Router above.
IP ADDRESS
Internet protocol address is a unique number that is used to represent every single computer in a network. All the computers on the Internet have a unique IP address. The format of the IP address is four numbers separated by dots (e.g., 198.123.456.7).
IP ID
The IP ID is a two-digit hexadecimal number that is used to differentiate a given device from a group of Ethernet devices in a control system with the same IP address. Just as the Net ID is used to distinguish between identical devices within a SIMPL Windows program, the IP address for a specific IP ID in the control system’s IP table must be set to the IP address of the given device. Furthermore, the IP ID in the given device’s static master table must be set to the IP address of the control system.
26 • Glossary of Terms Operations & Installation Guide – DOC. 8153A
IP MASK
An IP mask is a pattern of bits in IP address format (e.g. 255.255.255.0) which, when "and"ed with your IP address, produces a network address. If an outgoing packet's network address has the same network address as the source of the packet, it is sent on the local network wire, to be received by a device on that local network. Otherwise, it is sent to the gateway to be routed to a device existing on another network. The IP mask for any device should be assigned by whoever manages the local network. An IP mask is also referred to as a Subnet Mask.
IP TABLE
An IP table lists IP IDs and their corresponding IP addresses. This table is maintained inside each CNX control system, though it may be generated by a SIMPL Windows program, or edited manually using the Viewport utility.
NETWORK ADDRESS
A network address is a pattern of bits in IP address format that is shared by all network devices on a given local network. For example, network address
192.168.2.0 describes the local network where all devices have an IP address of
192.168.2.x, where x is any value from 1 to 254.
ROUTER
Router is a communications device which routes data between networks.
SUBNET MASK
See IP Mask above.
TCP/IP
TCP/IP stands for Transmission Control Protocol/Internet Protocol. It is quite simply a standard set of protocols that govern the basic workings of the Internet that was implemented in 1982.
The TCP part is all about ensuring that data is transmitted correctly between two computers. If any errors occur these are detected and the data is retransmitted. The data transmitted is split up into small portions called data packets. The IP part of TCP/IP is how these data packets are moved from one point to another. Each computer on the Internet has a unique IP address and the data packets are moved from the source to the destination through many different computers which is controlled via TCP/IP. This protocol is used on the Internet and also by computers which are part of a LAN.
