Crestron e-control™ Software Development Kit & CNX Gateway
Troubleshooting
If a Crestron e-control web page is not communicating to a control system, refer to
the following troubleshooting tips prior to calling Crestron for assistance.
1. Verify the CNX Gateway is running on the same PC as the Web
Server.
2. Verify the contents of the IP table match the IP address of the CNX
Gateway and the IP ID of the e-control page.
3. Verify the IP address in the HTML is a valid Crestron device (with
valid IP table).
4. Verify the IP ID in the SIMPL Windows e-control touchpanel symbol
matches the IP table entry and the contents of the HTML file.
5. If using Internet Explorer, check the “Address” field in the browser.
Verify the address is a network address and not a local path. For
communications to work, the page must come from a Web Server even
if the Web Server is on the same machine as the browser (Netscape
works off of the local file system). For example, to view the pages on
the same machine as the Web Server, type in the IP address of that PC,
then the path to the e-control pages.
6. Verify the Web Server’s home directory is pointing at the directory that
contains the e-control HTML files.
If after confirming these troubleshooting tips, the e-control page is still not
communicating to the control system, a call to Crestron technical support
(1-888-CRESTRON) may be necessary. However, before calling, be sure to have the
following information available. The support representative needs some or all of this
information to troubleshoot specific problems.
1. CNX Gateway Version.
2. SDK Version (obtained from the “Java console” when an e-control
page is loaded).
3. VT Pro-e Version.
4. Web Server Version.
5. Operating System Version and Service Pack (where CNX Gateway is
loaded).
6. Operating System Version and Service Pack (which the client
(browser) is using). This is not always the same as the CNX Gateway
machine.
7. Browser Version on the client machine. This is not always the same as
the CNX Gateway. A Java virtual machine must be installed.
8. Any error dialogs that appear when the page is loaded. If no error
dialogs appear, view the “Java console” for errors.
9. Verification that the IP address and the IP ID are in the HTML file.
10. Network configuration, including:
– IP address of CNX Gateway and Crestron devices.
– Sub net Mask.
– Contents of IP table.
11. OPS, Monitor, and TCP/IP Stack Versions.
