The options on this page are described below:
Port Settings
Allows a user to modify the server settings; specifically those port assignments associated with individual services.
All items can be either enabled/disabled via the Enabled checkboxes.
The port number values (except the FTP port) can be modified in this page.
The default port for each service is listed to the right.
Server Port Settings
The following table describes each of the Port Settings presented on this page:
Server Port Settings
Feature Description
Telnet: The port value used for Telnet communication to the target Master. Enabling this feature allows future
communication with the Master via a separate Telnet application (such as HyperTerminal).
• The default port value is 23.
• Refer to the NetLinx Security with a Terminal Connection section for more information on the related
procedures.
ICSP: The port value used for ICSP data communication among the different AMX software and hardware
products. This type of communication is used by the various AMX product for communication amongst
themselves. Some examples would be: NetLinx Studio communicating with a Master (for firmware or file
information updates) and TPDesign4 communicating with a touch panel (for panel page and firmware
updates).
• The default port value is 1319.
Note: To further ensure a secure connection within this type of communication, a user can enable the
Require Encryption option which requires additional processor cycles. Enabling of the encryption feature
is determined by the user.
HTTP: The port value used for unsecure HTTP Internet communication between the web browser’s UI and the
target Master. By disabling this port, the administrator (or other authorized user) can require that any
consecutive sessions between the UI and the target Master are done over a more secure HTTPS
connection.
By default, the Master does not have security enabled and must be communicated with using http:// in the
Address field.
• The default port value is 80.
Note: One method of adding security to HTTP communication is to change the Port value. If the port value
is changed, any consecutive session to the target Master has to add the port value at the end of the
address (within the Address field). An example is if the port were changed to 99, the new address
information would be: http://192.192.192.192:99.
HTTPS/SSL: The port value used by web browser to securely communicate between the web server UI and the target
Master. This port is also used to simultaneously encrypt this data using the SSL certificate information on
the Master as a key.
This port is used not only used to communicate securely between the browser (using the web server UI)
and the Master using HTTPS but also provide a port for use by the SSL encryption key (embedded into
the certificate). Whereas SSL creates a secure connection between a client and a server, over which any
amount of data can be sent securely, HTTPS is designed to transmit individual messages securely.
Therefore both HTTPS and SSL can be seen as complementary and are configured to communicate over
the same port on the Master. These two methods of security and encryption are occurring simultaneously
over this port as data is being transferred.
• The default port value is 443.
Note: Another method of adding security to HTTPS communication would be to change the port value. If
the port value is changed, any consecutive session to the target Master has to add the port value at the
end of the address (within the Address field). An example is if the port were changed to 99, the new
address information would be: http://192.192.192.192:99.
