VNC Mobile Application Configuration
Xpanel remote control is possible by smartphone when you use a general-purpose VNC Viewer application. Note that display color may differ in an application in which does not support a 16-bit color option.
Mobile network configuration |
(1) Mobile configuration in Mocha VNC Lite application
a) Search for a mobile viewer named ‘Mocha VNC Lite’ and install the application on the smartphone.
b) Tap the ‘Configure’ menu in the start menu of the application.
c) Tap the‘ New…’ button to establish a new network configuration.
d) Input the parameters of the Xpanel IP, port, and password. Enter the hash sign (#) in the password field, which indicates the nonuse of passwords. Tap [Save] to save the settings.
e) Go back to the start menu and tap the ‘Connect’ button. You can connect to the Xpanel with the corresponding configuration.
(2) Assigning a static IP address
When you wish to connect to the Xpanel via a 3G/LTE network, you must target a public IP address (append a port-forward to the public IP address for Xpanel’s with a local IP address). In the following example, you can connect to the VNC server with a static IP address or dynamic IP address. To use the VNC function in the mobile phone, a wireless network configuration is required. The following instruction explains the step for the mobile network through an IpTime device.
a) Input ‘192.168.0.1’ and click [Set up] to enter the settings window. Set remote Mgmt port by entering [Advanced Setup] -> [Firewall] -> [Mgmt Access List].
b) Check the [Remote Mgmt port #] box and set the number of the Management port.
c) The figure below is about how to set port forwarding to assign a socket port number in the IpTime. Go to [Advanced Setup] -> [NAT/Routing] -> [Port Forwarding] in the settings window.
d) Assign the static IP address and socket port number used in the Xpanel. The default socket port number used in the Xpanel is 5900.
e) Enter the static IP address and port number of the Xpanel at the configuration box in the application.
(3) Assigning dynamic IP address
a) Go to [Advanced Setup] -> [Utility] -> [DDNS] to register the address of the domain name.
b) Input the Host Name to register the DDNS server.
c) Go to [Advanced Setup] -> [NAT/Routing] -> [Port Forwarding] in the settings window. You can access the Xpanel via port number by entering the domain name.
d) Check the DHCP box so the Xpanel uses a dynamic IP address.
e) Enter the domain name and port number of the Xpanel in the configuration box of the application.
