Using the Web Interface

Overview

When Wi-Fi is enabled on the ZT-100, the device hosts a web interface that mirrors the front-panel controls and provides administrative tools.

Mobile App Availability

The app is available on the Apple App Store as Zonge ZT-100. An Android version is planned for release soon.

Hotspot mode (default):

  • Join the device Wi-Fi network (SSID typically ZT-100).

  • Open a browser and go to http://10.10.10.10/.

  • Or use the mobile app, which automatically connects to the correct network and IP address.

If the device is on a local network, use its IP address instead.

Main Page Controls

The main page shows GPS status, sync status, mode, and frequency. It also provides transmit control and the TX log.
