NetLinx Security - Web Server
Accessing an Unsecured Master via an HTTP Address
Refer to the Upgrading the On-board Master Firmware via an IP section on page 54 for more
detailed information on how to download the latest firmware from www.amx.com. This firmware
build enables SSL certificate identification and encryption, HTTPS communication, ICSP data
encryption, and disables the ability to alter the Master security properties via a TELNET session.
Once the Master’s IP Address has been set through NetLinx Studio version 2.4 or higher:
1. Launch your web browser.
2. Enter the IP Address of the target Master (ex: http://198.198.99.99) into the web browser’s
Address field.
3. Press the Enter key on your keyboard to begin the communication process between the target
Master and your computer.
Initially, the Master Security option is disabled (from within the System Security page)
and no username and password is required for access or configuration.
Both HTTP and HTTPS Ports are enabled by default (via the Manage System > Server
page).
4. The first active page displayed within your open browser page is Manage WebControl
Connections.
Browser Application Frames
A web page (FIG. 45) can be divided into separate sections or frames, each of which can be
independent of one another and display their own information.
Located on the left side of the populated Browser window is the Navigation frame which allows a
user to navigate throughout the application. Located on the right side of the Browser window is the
Active frame which displays the pages corresponding to the currently selected option from within
the Navigation frame.
The maximum length of a username or password is 20 characters. The minimum
length of a username or password is four characters. Characters such as # (pound)
& (ampersand) and ’ " (single and double quotes) are invalid and should not be
used in usernames, group names, or passwords.
Although Telnet security configuration access can no longer be used on a Master with this
firmware, a Terminal connection (using HyperTerminal) can still be established using the Master’s
RS232 Program port (if the Telnet Port is enabled via the Manage System > Server page).
Once HTTP Access is enabled for a Master; certificate verification and username and
password verification must occur. Refer to the Accessing an SSL-Enabled Master via
an IP Address section on page 130 for more information.
