You can connect any GNSS RTK receiver with SurPad 4.2 software using Bluetooth, Serial Port, and TCP Client methods.

TCP Client Connection Method

1. Prepare the Receiver:

• Configure your receiver to act as a TCP server. This involves setting up the receiver’s network settings, including assigning an IP address and port number.

2. Set Up the Receiver’s TCP Server:

• Access the configuration interface of your receiver (via a web interface or serial connection).

• Assign a static IP address and set a port for TCP communication (e.g., 2101).

3. Connect the Android Device:

• Ensure your Android device is connected to the same local network (Wi-Fi or wired) as the receiver.

4. Configure SurPad 4.2:

• Open SurPad 4.2.

• Navigate to the GNSS receiver setup section.

• Select "Device Manufacturer: Other" and choose "TCP Client" as the communication mode.

• Enter the IP address and port number of your receiver.

• Save the settings and connect.

5. Verify Connection:

• Ensure SurPad 4.2 is receiving data from the receiver.
