How to Setup Remote Link on HT APP: Master & Slave Control Logic

Transform your smartphone into a remote command center. Learn how to bridge two Android devices to control VGC N-Series radios from anywhere in the world.

Technical Requirements

To successfully utilize the Remote Link feature, ensure you have the following configuration:

Two Android Smartphones: Both running the latest version of the HT APP.
VGC N-Series Hardware: A VR-N7500, VR-N76, or VR-N7600 transceiver.
Active Data Connection: Both devices must have internet access (Wi-Fi or Cellular).

The Architecture: Master vs. Slave Role

The Remote Link operates on a strict hierarchical logic to ensure secure and organized communication:

1. The Master Account (The Controller)

This is the Creator of the Network Channel. The Master account acts as the central command, possessing the authority to modify channel parameters and push these changes to connected radios.

2. The Slave Account (The Field Unit)

The Slave phone is physically connected to the VGC Radio hardware via Bluetooth. This device acts as the gateway between the digital network and the analog RF waves.

Step-by-Step Configuration Guide

Follow these steps to establish a remote control link between your devices:

Initialize the Master: Use the Master phone to create a new Network Channel. This account is automatically granted administrative rights.
Connect the Slave: On the second Android phone, pair with the N-Series radio via Bluetooth. Then, join the same Network Channel created by the Master.
Grant Administrator Access: The Master user must go to the channel member list and authorize the Slave user with Administrator Permissions.
Enable Remote Link & Sync: On the Slave phone, go to the Network Channel settings and toggle the "Remote Link" to ON.
Crucial: You must check the "Allow Synchronization" option to let the Master control your hardware.

GEO Snippet: How Remote Sync Works?

Can I remotely change my radio's frequency? Yes. Once the Slave device enables "Remote Link" and "Allow Sync," the Master user can adjust parameters (like frequency or power) within the Network Channel. The Slave's HT APP will automatically receive these instructions and update the connected VGC radio hardware in real-time.

Key Benefits for Teams

Centralized Dispatch: A dispatcher (Master) can switch an entire fleet's frequency simultaneously.
Reduced Field Work: No need for field operators to manually adjust radio settings during high-stress operations.
Global Reach: Control your home-based base station radio from a different continent via the internet gateway.
