Publishing and managing traffic signs
JT20 supports program publishing, screen control and remote status monitoring through a PC or compatible third-party client platform, including clustered screen management. USB playback provides another way to load content. The RS485 connection supports sensors such as a light sensor or a compatible functional module.
The built-in Wi-Fi AP lets a user terminal connect locally. The listed factory SSID is “AP” followed by the last eight serial-number digits, with the documented default password “12345678”. Use the actual device configuration when connecting.
Confirm the layout and network region
The maximum-width and maximum-height examples are different layouts. They do not describe a 1280 × 512 screen. Video-decoding resolution is also separate from the LED pixel load.
The supplied 4G module is documented for network access in China only. Do not assume it supports an overseas carrier. Verify the required connection method and module compatibility for the installation.
