Server Port Settings
Feature
Description
Telnet Port:
The port value used for Telnet communication to the target Master.
• The default port value is 23.
• Enabling this feature allows future communication with the Master via a
separate Telnet application (such as HyperTerminal).
• Refer to the
NetLinx Security with a Terminal Connection
section for more
information on the related procedures.
ICSP Port:
The port value used for ICSP data communication among the different AMX
software and hardware products.
• The default port value is 1319.
• 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).
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 Port:
The port value used for unsecure HTTP Internet communication between the
web browser’s UI and the target Master.
• The default port value is 80.
• By default, the Master does not have security enabled and must use
http://
in
the
Address
field for communication.
• One method of adding security to HTTP 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).
For example, if the port were changed to 99, the new address information
would be:
http://192.192.192.192:99
.
• 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.
