NXP-TPI/4 NetLinx Touch Panel Interface
G4 Web Control Page
The G4 Web Control page (FIG. 53) centers around enabling and disabling both the display and control
of your TPI/4 (via the web). An external PC running a VNC client (installed during the initial
communication to the G4 device) makes this possible.
Each G4 device supports the open standard Virtual Network Computing (VNC) interface. This device
contains a VNC server which allows it to accept a connection from any other device running a VNC
client. Once a connection is established to that target device, the client can control the TPI/4 remotely.
The elements of the G4 Web Control page are described in the table below:

Back: Saves the changes and returns you to the previously active touch panel page.
Connection Status icon: This visual display of the connection status allows the user to have a current
update of the TPI/4’s connection status regardless of what page is currently
active.
• A Lock only appears on the icon if the TPI/4 has established a connection with
a currently secured target Master (requiring a username and password).
