Configuring Communications
Using your NetLinx Master to control the G4 panel
Refer to your particular NetLinx Master’s instruction manual for 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.
In order to fully utilize the SSL encryption, your web browser should incorporate the an encryption feature. This encryption level is displayed as a Cipher strength.
Once the Master’s IP Address has been set through NetLinx Studio version 2.x 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).
If the Master has been previously configured for secured communication, click OK to accept the AMX SSL certificate (if SSL is enabled) and then enter a valid username and password into the fields within the Login dialog.
4.Click OK to enter the information and proceed to the Master’s Manage WebControl Connections window.
5.This Manage WebControl Connections page (FIG. 33) is accessed by clicking on the Manage connections link
(within the Web Control section within the Navigation frame). Once activated, this page displays links to G4 panels running the latest G4 Web Control feature (previously setup and activated on the panel).
