Terminal (Program Port/Telnet) Commands
Overview
There are two types of terminal communications available on NetLinx Integrated Controllers:
Program Port - The "Program" port is a Type-B USB port located on the front panel of the Master that
allows terminal communication with the Master. This type of terminal communication requires that you are
physically connected to the Master to access the configuration options and commands supported. Since this
method of terminal communication requires physical proximity as well as a physical connection to the
Master, it is the most secure form of terminal communication.
For this reason, all Security Configuration options are only available via the Program port (and cannot be
accessed via Telnet).
Telnet - This type of terminal communication can be accessed remotely, via TCP/IP. It is a less secure form of
terminal communication, since it does not require a physical connection to the Master to connect. Further, the
Telnet interface exposes information to the network (which could be intercepted by an unauthorized network
client).
Note: It is recommended that you make initial configurations as well as subsequent changes via the WebConsole. Refer
to the On-Board WebConsole User Interface section on page 19.
Refer to the Terminal Commands section on page 91 for a listing of all commands available in a terminal session.
Note that all commands in the table are available for both Program Port and Telnet sessions, with two exceptions: "Help
Security" and "Resetadminpassword". These commands are only available via a Program Port connection.
Establishing a Terminal Connection via the Program Port
To establish a terminal session via the Program Port, the USB port on your PC must be physically connected to the
Program port on the NetLinx Master.
Establishing a Terminal Connection via Telnet
1. In your Windows task bar, select Start > Run to open the Run dialog.
2. Type cmd in the Open field and click OK to open an instance of the Windows command interpreter (cmd.exe).
3. In the CMD (command), type "telnet" followed by a space and the Master’s IP address info.
Example:
>telnet XXX.XXX.XXX.XXX
4. Press Enter.
Unless Telnet security is enabled, a session will begin with a welcome banner:
Welcome to NetLinx vX.XX.XXX Copyright AMX Corp. 1999-2006
>
If Telnet security is enabled, type in the word login to be prompted for a Username and Password before
gaining access to the Master.
5. Enter your username to be prompted for a password.
If the password is correct, you will see the welcome banner.
If the password is incorrect, the following will be displayed:
Login: User1
Password: *****
Login not authorized. Please try again.
After a delay, another login prompt will be displayed to allow you to try again.

the connection closed:
