Quick Start

Initial Setup

• Power & Connect: Attach the appropriate antennas and power sources. Ensure the CPU LED is solid blue.
• Access WebUI: Connect your PC to the LAN port. Set your PC's network to DHCP or a static IP (e.g., 192.168.168.10 / 255.255.255.0).
• Login: Open a browser and navigate to 192.168.168.1. Log in with the default credentials (admin / admin) and follow the prompt to change your password.

Auto-Configuration (Quickest Method)

• Master: Press and hold the CFG button for at least 10 seconds until the CPU LED flashes, then release. It will auto-configure as Master (IP: 192.168.168.1).
• Slave: On the second unit, press and hold the CFG button for 5 seconds until the CPU LED flashes, then release. It will auto-configure as Slave (IP: 192.168.168.2).
• Host Synchronization: Note that after auto-configuration, the host device's Ethernet settings must be compatible with the new IP scheme and network negotiation of the module. Ensure the host is set to match the Auto-negotiation or specific Speed/Duplex settings required by the link.
• Verify: Wait ~60 seconds. Solid RSSI LEDs on the units indicate a successful wireless link.

Manual Configuration (For Custom Networks)

If you require specific network settings (IP addresses, specific Network IDs):

• Set IP: Navigate to Network > LAN and assign a unique static IP to each unit.
• Configure RF: Navigate to Wireless > RF.
  • Set the Operation Mode (Master for the first unit, Slave for the second).
  • Ensure both units have the exact same Network ID, Compatibility Mode, Channel Bandwidth, and Frequency.
  • Click Submit to save changes.
• Test: Connect a PC to the Master unit, enter the Slave’s IP address into a browser, and confirm you can access the Slave’s WebUI over the wireless link.
