Configuring the WT-4 for Upload to a Computer (Ad-hoc Mode) Mac OS X (10.5.2)

1: Get Ready

Equipment
Ready the following: A WT-4 wireless transmitter * A fully-charged EN-EL3e battery for the WT-4 A Nikon D3 or D300 digital SLR camera A fully-charged battery for the camera (an EN-EL4a for the D3, a EN-EL3e for the D300) A computer with Mac OS X (10.5.2) *, the WT-4 Setup Utility* installed A memory card A USB cable Manuals for the above equipment

Network Settings

Note the IP addresses, encryption, and other settings that will be used in the wireless LAN. The following are intended as examples only. IP address for the WT-4: 192.168.1.4 IP address for the computer 192.168.1.3 Subnet mask: 255.255.255.0 Network name (SSID): WT-4 Communication mode: Ad hoc Channel: 1 Authentication: open system Authentication: WEP64 Encryption key: abc12 Key Index: 1 * WT-4 firmware version 1.1 and the WT-4 Setup Utility version 1.1 are required when using the WT-4 under Mac OS X version 10.5.2. Updates to the WT-4 firmware and Setup Utility are available on the Nikon website for your area.
2: Assign the Computer an IP Address
Choose an address for the computer. The following IP address is intended as an example only. IP address: 192.168.1.3 Subnet mask: 255.255.255.0
Open System Preferences and click Network.
Select AirPort. Click Advanced.
Select Manually from the Configure IPv4 menu and enter an IP address and sub-net mask. Click OK to return to the previous dialog and then click Apply. This completes the process of assigning an IP address to the computer.

3: Configure the Network

Click the action button and select Set Service Order.
Move AirPort to the top of the services list and click OK.
After selecting AirPort and confirming that the service is active and that Show AirPort status in menu bar is checked, click Apply. If AirPort is off, click Turn AirPort On.
Click the AirPort status icon in the menu bar and select Create Network.
After choosing a network name and channel and adjusting encryption and password options as described below, click OK.
Name: Enter a name of up to 32 characters. The network in this example uses the identifier WT-4. Channel: Choose a channel. Require Password: Select this option to enable WEP encryption. Password: If WEP encryption is enabled, enter a security key. The length of the key depends on the option selected for Security: - 40-bit (more compatible): Enter a five-character ASCII or ten-digit hexadecimal key. - 128-bit: Enter a 13-character ASCII or 26-digit hexadecimal key. ASCII keys may contain letters, punctuation, and the numbers 09, hexadecimal keys the numbers 09 and the letters a, b, c, d, e, and f. Security: Choose the length of the WEP key.

Open the System Preferences > Network panel and confirm that the Network Name is the same as that specified in 3 - 6. Network setup is now complete.
4: Copy the Network Profile to the Camera
Use the WT-4 setup utility to copy the network profile to the camera. Before proceeding, make sure that MTP/PTP is selected for the USB option in the camera setup menu.
After starting the computer, use the supplied USB cable to connect the camera and turn the camera on.
Click the WT-4 Setup Utility icon in the Dock.
The dialog shown below will be displayed; click Next.
Select Add/Edit profiles and click Next.
Select Add new profile and click Next.

Enter the following information and click Next. Network name (SSID): WT-4 Communication mode: Ad hoc Channel: 1 Authentication: None (open networks only) Encryption: WEP64 Encryption key: abc12 Key Index: 1
Enter the following information and click Next. IP address: 192.168.1.4 Subnet mask: 255.255.255.0 Default gateway: Remove the check from this option. DNS Server: Remove the check from this option.

Choosing an IP Address

Be sure that the address for the WT-4 is different from the address used for the computer. The addresses for computer and WT-4 must however belong to the same class. In this example, we will use 192.168.1.3 for the computer and 192.168.1.4 for the WT-4.
Confirm that settings are correct and click Next.

Select Finish wizard and click Next.

4 - 11

Turn the camera off and disconnect the USB cable. The network profile has now been copied to the camera.
5: Connect to the Computer
In this step, you will establish a wireless connection between the WT-4 and the computer. Before connecting the WT-4, select MTP/PTP for the USB option in the camera setup menu and confirm that the host computer is running and the user is logged in.
Insert a memory card in the camera, connect the WT-4, and turn the camera on.
Choose an option for the Wireless transmitter > Mode option in the camera setup menu.
A list of available connection profiles will be displayed. Highlight the desired profile and press J.
Return to the wireless transmitter menu and turn the WT-4 on. The profile name will be highlighted in green when a connection is established. This completes the process of connecting to the computer.

Third-Party Security Software
Third-party security software with firewall support may block the ftp server port, preventing access to the computer. This can be avoided by setting the software to allow protocols send and receive access to TCP ports 15740 and UDP ports 5353. For more information, see the documentation for the software or firewall.
