1. Introduction
The Nikon WT-6 Wireless Transmitter is an accessory designed for compatible Nikon cameras, such as the Nikon D5, to facilitate wireless transfer and remote control functionalities. It enables photographers to transfer images and videos using Wi-Fi technology, either through an existing Wireless LAN network or directly to a computer or smart device.
The WT-6 supports various operational modes including FTP, HTTP Server, PC, and Image Transfer. It is compliant with IEEE802.11ac for high-speed data transmission, also supporting IEEE802.11a/b/g/n standards. The device offers a communication range of up to 656 feet (200 meters) and supports data transfer speeds up to 130 Mbps.

2. Setup and Connection
Proper setup of the WT-6 is crucial for reliable wireless communication. This section outlines the general steps for connecting the transmitter to your camera and establishing a network connection.
2.1 Attaching the WT-6 to the Camera
- Ensure the camera is powered off before attaching the WT-6.
- Align the WT-6 connector with the camera's dedicated accessory terminal.
- Gently push the WT-6 into place until it clicks securely.
- Use the locking mechanism on the WT-6, if present, to secure it firmly to the camera body.

2.2 Establishing a Wireless Connection
After attaching the WT-6, power on your camera. Navigate to the camera's setup menu to configure the wireless settings. The WT-6 supports two primary connection methods:
- Connect to an Existing Network (Infrastructure Mode): This mode allows the camera to connect to a Wi-Fi router or access point. Select this option in the camera's network settings, then choose your desired network and enter the password if required.
- Direct Connection (Ad-Hoc Mode): This mode creates a direct Wi-Fi connection between the camera and a computer or smart device. Select this option, and then connect your computer or smart device to the Wi-Fi network broadcast by the WT-6.
Refer to your camera's instruction manual for detailed steps on configuring network settings specific to your camera model.
3. Operating Modes
The WT-6 offers several modes for wireless operation, each serving a distinct purpose:
3.1 FTP Mode
FTP (File Transfer Protocol) mode allows for the automatic or manual transfer of images and videos from the camera to an FTP server. This is ideal for quickly backing up files or sending them to a remote location.
- Configure FTP server details (address, username, password) in the camera's network settings.
- Select images for transfer or set up automatic transfer after each shot.
3.2 HTTP Server Mode
HTTP Server mode enables remote control of camera functions and image/video download using a web browser on a computer or smart device (iPhone, iPad, Android). This mode does not require a dedicated application.
- Connect your device to the WT-6's Wi-Fi network (or the same LAN if in infrastructure mode).
- Open a web browser and enter the camera's IP address (found in camera network settings).
- From the web interface, you can remotely operate camera controls, take pictures, download images or videos, and edit image comments, copyright, or IPTC information. Continuous shooting is also supported.
3.3 PC Mode
PC mode is used for controlling the camera remotely via Nikon's optional Camera Control Pro 2 software. This software provides advanced control over camera settings and tethered shooting capabilities.
- Ensure Camera Control Pro 2 software is installed on your computer.
- Connect your computer to the WT-6's Wi-Fi network (or the same LAN).
- Launch Camera Control Pro 2 and establish a connection with the camera.
3.4 Image Transfer Mode
This mode allows for the transfer of images or videos from the camera's media card to a connected computer. It can also be configured to save photos to a computer as they are taken (tethered shooting without Camera Control Pro 2).
- Connect your computer to the WT-6's Wi-Fi network (or the same LAN).
- Access the camera's storage from your computer as a network drive or through compatible software.
4. Maintenance
To ensure the longevity and optimal performance of your Nikon WT-6 Wireless Transmitter, follow these maintenance guidelines:
- Cleaning: Use a soft, dry cloth to clean the exterior of the transmitter. Avoid using abrasive cleaners, solvents, or strong chemicals, as these can damage the finish or internal components.
- Storage: When not in use, store the WT-6 in a cool, dry place away from direct sunlight, extreme temperatures, and high humidity. Detach it from the camera if storing for extended periods.
- Handling: Handle the transmitter with care. Avoid dropping it or subjecting it to strong impacts, which can cause internal damage.
- Connectors: Keep the electrical contacts clean and free of dust or debris. Avoid touching the contacts directly.
5. Troubleshooting
If you encounter issues with your WT-6 Wireless Transmitter, refer to the following troubleshooting tips:
- Difficulty with Setup/Connection:
- Ensure the WT-6 is securely attached to the camera and the camera is powered on.
- Verify that the correct wireless mode (Infrastructure or Direct) is selected in the camera's network settings.
- Double-check Wi-Fi network names (SSID) and passwords.
- Restart both the camera and the receiving device (computer/smart device).
- Connection Drops Frequently:
- Check the distance between the camera/WT-6 and the receiving device or Wi-Fi router. The maximum range is 656 ft (200m), but obstacles can reduce this.
- Minimize potential sources of interference (e.g., other wireless devices, microwave ovens).
- Ensure the camera's battery has sufficient charge.
- Image Quality/Resolution Issues in HTTP Server Mode:
- When using HTTP Server Mode via a web browser on a smart device, the displayed or downloaded images may be lower resolution previews. For full-resolution image transfer, utilize FTP Mode, PC Mode with Camera Control Pro 2, or Image Transfer Mode.
- No Dedicated App for Smart Devices:
- The WT-6's HTTP Server Mode is designed to be accessed via a standard web browser on smart devices, not a dedicated mobile application. Ensure you are using your device's web browser to access the camera's IP address.
