WEP (Wired Equivalent Privacy) encryption stops unauthorized devices from using your wireless network and protects your wireless communications from eavesdropping.
WEP (Wired Equivalent Privacy) encryption scrambles all data packets transmitted between the DMA and the AP or other wireless stations to keep network communications private. The wireless stations and access point must use the same WEP key for data encryption and decryption. Encryption is like a secret code. If you do not know the secret code, you cannot decrypt (unscramble) the message.
If you do not use WEP with your DMA, the DMA’s wireless communications are accessible to any wireless networking device that is in within range.

9.7.1 Wireless LAN Setup Using Windows® Connect Now
Windows® Connect Now lets you save your computer’s wireless settings to a USB memory stick. Then you can connect the USB stick to the DMA to configure the DMA’s wireless settings. This allows you to easily set up a wireless LAN. To take advantage of this feature, you need:
• A USB memory stick with at least 300K of available memory. • Windows XP with Service Pack 2 (SP2).
Follow the steps below to set up a wireless LAN using Windows® Connect Now. You do not need to connect the USB stick to the computer yet, you will be prompted to do so later.
1 Click Start > Control Panel and double-click Wireless Network Setup Wizard.
Cryptography Key The DMA uses a WEP key to encrypt data. All the devices on the wireless LAN must use the same WEP key for data transmission.
Your DMA allows you to configure up to four 64-bit or 128-bit WEP keys. Only one key is used as the default key at any one time. The default key is key 1. Use the (smaller) field on the left to select a key to configure and then select the (larger) field on the right and use the on-screen keyboard screen (see Section 4.2.1 on page 36) to enter the key.
A key can be 5 ASCII characters or 10 hexadecimal characters ("0-9", "A-F") if your network is using 64 bit WEP.
A key can be 13 ASCII characters or 26 hexadecimal characters ("0-9", "A-F") if your network is using 128 bit WEP.
Note: The values for the WEP keys must be set up exactly the same on all wireless devices in the same wireless LAN. Note: ASCII WEP keys are case sensitive.

9.8 Video Modes
The DMA supports 480i, 480p, 720p and 1080i video modes. 720p and 1080i are high definition television modes. 480i is used with most standard definition televisions. The number (“1080” for instance) stands for the number of lines of vertical resolution. The letter “i” stands for interlaced scan. The letter “p” stands for progressive scan. Progressive scan provides higher picture quality than interlaced but requires twice the bandwidth.
