Setup
Hardware Setup of CNMSX
Follow these steps to enable Ethernet communications in your CNX control system:
1. Install the CNXENET Direct Processor Access (DPA) card into the
CNMSX. Refer to the CNXENET manual (latest revision of Doc.
8129) for instructions.
2. Connect your PC to the CNMSX computer port via a serial cable, as
usual. Refer to the CNMSX manual (latest revision of Doc. 8118) for
instructions.
3. Ensure you have installed SIMPL Windows version 1.21.03 or later.
4. Run SIMPL Windows. Verify that the control system has been loaded
with proper versions of firmware. To check the versions currently
installed, run the Viewport by selecting it from the Tools menu. Once
in the Viewport, select File Transfer|Update Control System to bring
up a dialog box containing the current versions of monitor, operating
system, and TCP/IP stack. Verify the versions per the “Leading
Specifications” on page 8.
If you need to upgrade any of these files, you can retrieve a copy of the
latest upgrade package from the Crestron website (ECONTROL
Library). These files have an extension of .upz which contains all three
system components in one compacted file. Once you have downloaded
the appropriate file, browse for it in the “Upgrade Control System”
dialog box. Select Send to upload the files to the control system. When
upgrading the system in this manner, always send all three components
to avoid incompatibilities.
It may be necessary to upgrade to an intermediate version of the
monitor first and then to the required version of the monitor, but the
Viewport will notify you if this is necessary. After you have completed
this step, you may disable the TCP/IP stack if you do not intend to use
it now; set the control system’s IP address to 0.0.0.0 using the
Viewport. This will provide more memory for your program, but of
course will disable Ethernet communications.
5. Assign an IP address to the control system using the Viewport by
selecting Functions|Set Control System IP Information. This will
allow you to assign an IP address, a gateway address, and a subnet
mask (see these terms defined later in this document for more
information). These addresses should be obtained from your MIS
department. The IP address must be unique. IP addresses have four
fields separated by periods (e.g. 192.168.2.3).
6. Connect your control system to the Ethernet network. Your PC may
communicate to the control system either via Ethernet (if it is equipped
with a network card and has been properly set up with a unique IP
address itself), or continue to operate via the serial connection.
7. Test the IP address of the control system by “pinging” it: From a
networked PC bring up an MS-DOS prompt (Windows 95/98) or
“Command Prompt” (Windows NT) and type “ping <ip _address>”, as
shown after this step. The control system responds with several lines
