Once any of the server port settings have been modified, press the Accept button to save these changes to the Master. 
Once these changes are saved, the following message appears: "Unit must be rebooted for the change to take effect".
Click the Reboot button (from the top of the page) to remotely reboot the target Master. No dialog appears while using 
this button. The Device Tree then reads "Rebooting....". After a few seconds, the Device Tree refreshes with the current 
system information (indicating updated port numbers).
Server Port Settings (Cont.)
Feature Description
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.
SSH: • The port value used for secure Telnet communication. A separate secure SSH Client would handle 
communication over this port. When using a secure SSH login, the entire login session (including the 
transmission of passwords) is encrypted; therefore it is secure method of preventing an external user 
from collecting passwords.
• SSH version 2 is supported.
• The default port value is 22.
Note: If this port’s value is changed, make sure to use it within the Address field of the SSH Client 
application.
FTP: The default port value used for FTP communication = 21. 
Note: This port can be disabled/enabled but the value can not be changed.
If the Device Tree contents do not refresh within a few minutes, press the browser’s 
Refresh button and reconnect to the Master.
