NetLinx Security with a Terminal Connection

NetLinx Security - Terminal
Initial Setup via a Terminal Connection
Security administration and configuration is done via a Terminal communication through the
RS232 Program port on the NetLinx Master. If you connect to the target Master via the TCP/IP
(Winsock) option, you will find that some command sets (such as the security setup) will not be
available. If you have a valid IP connection method to the Master, it is recommended that you
make your changes to the parameters via the browser-based UI pages.
Establishing a Terminal connection via the RS-232 Program Port
1. Launch the HyperTerminal application from its’ default location (Start > Programs >
Accessories > Communications).
2. Apply power to the NetLinx Master and allow it to boot up.
3. Connect the PC COM (RS232) port from your computer to the RS232 Program port on the
NetLinx Master. Note the baud rate settings for the Master.
4. Enter any text into the Name field of the HyperTerminal Connection Description dialog
window and click OK when done.
5. From the Connect Using field, click the down-arrow and select the PC COM port being used
for communication by the target Master and click OK when done.
6. From the Bits per second field, click the down-arrow and select the baud rate being used by the
target Master.
 Configure the remaining communication parameters as follows: Data Bits: 8,
Parity: None, Stop bits: 1, and Flow control: None (default is Hardware).
 Click OK to complete the communication parameters and open a new Terminal window.
7. Type echo on to view the characters while entering commands. If that does not work, press
<Enter> key on your keyboard.
Accessing the Security configuration options
1. In the Terminal session, type help security to view the available security commands. Here is a
listing of the security help:
---- These commands apply to the Security Manager and Database ----
logout Logout and close secure session
setup security Access the security setup menus
Although these procedures are written for a Terminal connection, a user can also
connect to a Master via a Telnet connection. Do this by going to Start > Run, enter
cmd within the Run dialog’s Open field and click OK. Then from within the CMD
command prompt use the IP Address info to type >telnet XXX.XXX.XXX.XXX
<Enter>.
It is very important for a user properly execute the 'logout' command prior to
disconnecting from a Master. Simply removing the RS-232 connector from the
Program Port maintains your logged-in status until you either return to logout
via a new session or reboot the target Master.
The 'help security' and 'setup security' functions are only available via a direct RS232
Program port connection. They are not available under telnet (such as via a TCP/IP
(Winsock) connection).
