NetLinx Security with a Terminal Connection
118
NI-3101-SIG Signature Series NetLinx Integrated Controller
Initial Setup via a Terminal Connection
Security administration and configuration is done via a Terminal communication through the RS232/
USB Configuration Port on the NetLinx Master. If connecting to the target Master via the
TCP/IP
(Winsock)
option, some command sets (such as the security setup) will not be available.
If a valid IP
connection method has been made to the Master, making changes to the parameters via the browser-
based UI pages is highly recommended.
Establishing a Terminal connection via the RS-232/USB Configuration 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 USB port from your computer to the USB connector on the NetLinx 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 the
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 that a user properly execute the 'logout' command prior to
disconnecting from a Master. Simply removing the USB connector from the
Configuration Port maintains a logged-in status until either a return to logout
via a new session or reboot of the target Master.
The 'help security' and 'setup security' functions are only available via a direct
RS232/USB connection. They are not available under telnet (such as via a TCP/IP
(Winsock) connection).
