DISPLAX Service – Available Device Parameters

Overview

DISPLAX Service allows you to retrieve a complete list of available parameters and command options supported by a specific connected device. This ensures you only use parameters that are valid for the selected touch controller and firmware version.

This is especially important when working with advanced settings, automation, or remote device management.

How to View Available Parameters for a Device

To display all supported parameters for a specific device, use the device help command.

You can use either of the following options:

  • -g

  • --device-help

Example: Local Device (Same Computer)

To list all available parameters for a device connected to the local computer, use the localhost IP address:

displaxservice -a 127.0.0.1 -g

or

displaxservice -a 127.0.0.1 --device-help

Example: Remote Device (Same Network)

To list available parameters for a device connected to another computer on the same network, use that computer’s IP address:

displaxservice -a 192.168.1.50 -g

or

displaxservice -a 192.168.1.50 --device-help

What the Command Returns

The output includes:

  • A list of supported parameters for the selected device

  • Descriptions of each parameter

  • Accepted values (where applicable)

This information reflects the actual capabilities of the connected device, helping prevent unsupported or invalid commands.

When to Use This Command

Use the device help command when:

  • Preparing to change device parameters

  • Verifying parameter availability for a specific controller

  • Writing scripts or automation workflows

  • Troubleshooting unexpected command behavior

  • Working with different device models or firmware versions

Best Practices

  • Always run the device help command before modifying parameters.

  • Use localhost (127.0.0.1) when managing devices on the same machine.

  • Confirm remote network access is enabled before querying remote devices.

  • Keep a record of supported parameters for complex installations.
