Java Path

The path to the Java executable on the Ignition Gateway server machine. The Java 7 JRE is required for the mobile module. The default is java, which assumes that Java 7 is on the path and can be invoked merely with the java keyword.

Client Memory

The max amount of heap space allowed for each mobile client VM that is launched. Mobile clients are virtual clients that are launched on the server. All of the work is done on the server and transmitted to the mobile device so keep in mind that more mobile clients means more memory and CPU consumption on the server.

JVM Options

Command-line JVM options to use when launching mobile client VM's. Multiple options are separated with spaces. This option is made available mostly for troubleshooting by technical support staff, but if you are familiar with java and comfortable with command-line arguments, you can specify ones you may find useful.

Environment Variables

The environment variables to pass to the mobile client VM process. Use the NAME=VALUE format, one per line.

Idle VMs

The number of client VMs to startup and wait for incoming mobile connections. These will start when the Gateway is started and sit idle until a mobile connection is made. This should be left at the default value of 0 unless it is taking a long time to launch a mobile client. It's important to note that the VMs that are sitting idle are not connected to a project so it will still take time to load the selected project.

Server Address

This is the address to use when launching from the QR code on the launch page. This is a setting that often causes confusion. Initially this value is blank by default which results in the QR code pointing to the address of http://localhost:8088/. Since Ignition is not running on your mobile device, this address will not actually launch the mobile homepage. This should be set to the Ignition server address that can be reached by the mobile device.

Callback Port

The port that the mobile Client VMs use to communicate to the Gateway on. The default is 45900, but if this port is already in use, you need to change this to an available port.

Callback Interface

The interface that mobile client VMs should use to communicate back to the Gateway on. The default, localhost, makes use of the loopback adapter, however if this host doesn't have a loopback adapter or if there are two network cards, set this to the IP address of the NIC that should be used for local loopback.

AJAX Timeout

The max time, in milliseconds, that each request has to complete. The default is 10,000 (10sec).

Enable VNC

Allows direct thin-client connection over VNC (also known as, RFB) protocol.

VNC Port

The port used for the VNC connections.

Project Name

The Mobile module only allows one of the projects on the Ignition Gateway to be viewed through VNC so you have to specify that project here. Unlike the normal mobile launch screen that allows you to choose a project, the project that you specify in this setting will be automatically launched when you connect via a VNC viewer application.

Project Width

The width of the project when it's launched.

Project Height

The height of the project when it is launched.
