Quick Start

2026-03-24

This section guides you through the initial power-on and basic connection of the T256s. For detailed functional descriptions, please refer to the User Guide (UG).

Power Supply Instructions

The T256s does not have a built-in battery. You can power the device using any of the following methods:

  • Direct Phone Connection: Plug the device directly into the Type-C port at the bottom of your smartphone (requires OTG power support).
  • External Power: Connect to a power bank, USB wall adapter, or a PC USB port via the Type-C male or female connectors.

[!IMPORTANT]
Power Requirements: A stable 5V power supply is highly recommended. Insufficient power may lead to continuous reboots or screen flickering.

Standalone Inspection Mode

Without connecting to a phone or computer, the T256s can function as an independent, portable thermal imager. Simply connect it to a power source to begin inspection.

Startup Workflow:

  1. Power On: Connect power via the Type-C female port; the screen will immediately light up and display the boot logo.
  2. System Loading (Approx. 3-5s): The system automatically initializes and loads the basic UI framework.
  3. Sensor Warm-up & Calibration (Approx. 5-10s): The infrared module completes its initial calibration, and the screen begins displaying real-time thermal distribution images.

UVC Online Mode

The T256s complies with the standard UVC (USB Video Class) protocol. On major operating systems (Windows, Linux, Android), the device is recognized as a driverless camera, eliminating the need for additional driver installations.

Windows Connection

Connect the T256s to your PC via a USB data cable.

  • Device Recognition: Open "Device Manager." Under the "Cameras" or "Imaging Devices" category, you should see a device named "USB Camera" or "T256s Thermal Camera."
  • Image Preview: You can use the built-in Windows "Camera" app or third-party software such as OBS Studio, VLC, or PotPlayer.

Linux / Raspberry Pi Recognition

In a Linux environment, the T256s is typically mapped to a /dev/videoX device.

  • Recommended Tools: Use guvcview, cheese, or ffmpeg for testing.
  • Log Verification: After plugging in the device, execute the dmesg command in the terminal to view recognition logs.
