4. Setup and Installation
4.1. Physical Installation
- Mounting: The W712 supports both desktop and wall-mounted installation. Choose a stable location with good ventilation and away from direct heat sources or moisture. For wall mounting, use appropriate screws and anchors (not included) to secure the device.
- Attach Antenna: Carefully screw the provided antenna onto the antenna connector on the rear panel of the W712. Ensure it is securely fastened but do not overtighten.
- Power Connection:
- Using Power Adapter: Connect the DC 12V power adapter to the power input port on the W712, then plug the adapter into a standard electrical outlet.
- Using PoE+: If your network switch supports PoE+, connect an Ethernet cable from the PoE+ enabled port on your switch to one of the Ethernet ports on the W712. The device will power on automatically.
- Network Connection: Connect an Ethernet cable from your network router or switch to one of the Ethernet ports on the W712. The device features dual Megabit Ethernet ports.
- Insert TF Card (Optional): If you plan to use a TF card for data storage or offline firmware upgrades, insert it into the TF card slot.
- Connect USB Device (Optional): If needed, connect a USB device to the USB 2.0 port.
4.2. Initial Configuration Access
Once powered on and connected to the network, the W712 can be configured via its web management interface.
- Obtain IP Address: The W712 will typically obtain an IP address automatically via DHCP. You may need to check your router's DHCP client list to find the assigned IP address of the device. Alternatively, use a network scanning tool.
- Access Web Interface: Open a web browser on a computer connected to the same network as the W712. Enter the device's IP address into the browser's address bar and press Enter.
- Login: You will be prompted for a username and password. Refer to the Quick Installation Guide for default login credentials. It is highly recommended to change the default password immediately after the first login for security purposes.
5. Operating Instructions
The W712 gateway functions by integrating radio communication with SIP-based communication. Configuration is primarily done through the web management interface.
5.1. Radio Module Configuration
Within the web interface, navigate to the radio settings to configure the 400-470MHz radio module. This includes:
- Frequency Settings: Set the operating frequencies for communication with two-way radios.
- Channel Configuration: Define radio channels and associated parameters.
- Compatibility Settings: Adjust settings for compatibility with specific analog or DMR II digital radio models (e.g., Motorola, Hytera).
- Audio Settings: Configure audio input/output levels for the radio interface.
5.2. SIP Module Configuration
Access the SIP settings in the web interface to integrate the W712 with your SIP communication system:
- SIP Account Registration: Register the W712 with your SIP server by entering SIP account details (username, password, server address).
- Codec Preferences: Select preferred audio codecs, including G.722 and Opus for HD audio.
- Network Settings: Configure network parameters relevant to SIP communication (e.g., NAT traversal).
5.3. RoIP Link Configuration
This section defines how radio channels are mapped to SIP extensions or groups, enabling cross-platform communication.
- Mapping Rules: Create rules to link specific radio channels to SIP endpoints or vice versa.
- Group Calls: Configure group call functionalities between radio users and SIP users.
- Priority Settings: Assign priorities for different communication paths if necessary.
5.4. Call Recording and Logs
The W712 supports recording calls and maintaining call logs for both two-way radios and SIP phones. These features can be configured and accessed via the web interface. Ensure sufficient storage is available on the TF card or connected USB device if local storage is used for recordings.
6. Maintenance
