Getting Started

BEFORE YOU BEGIN! Read the section on using the DVC-1100 with routers, gateways or broadband modems starting on page 47 in this manual if you are using the DVC-1100 VideoPhone with a router, gateway or broadband modem.

The DVC-1100 needs to be setup before use. You can use the Quick Installation Guide (included with the DVC-1100) to perform the hardware

installation. Each cable (video, audio, Ethernet and AC power) supplied for the DVC-1100 has a different color on the end that connects to the DVC-1100. Plug the cables into the matching color coded connector on the back of DVC-

1100. You can also plug an optional telephone and/or external microphone into the DVC-1100. If you are using the DVC-1100 wirelessly, screw the included antenna into the antenna connector on the back of the DVC-1100. To help you with these connections, there is an illustration on the bottom of the unit.

There is an easy to use Setup Wizard built-in to the DVC-1100 to accomplish the setup. You will need to enter your name, a videophone number, wireless network settings and your Internet connection information in order to use your VideoPhone.

Using the Remote Control

By using the remote control included with the DVC-1100, you can answer an incoming call, start a call by dialing the other videophone’s number or select a number to call from the Speed Dial list.

Information for the Setup Wizard is entered by using the remote control. The remote is used to enter numbers, letters, special characters and to make selections from an on-screen keyboard. The on-screen keyboard is activated by pressing ENTER on the remote control whenever the on-screen cursor is located in a field where text is required.

You will use the arrow keys on the remote control along with the ENTER, CANCEL and number keys to enter information in the Setup Wizard screens.

Where a numeric input is required, such as a telephone number or IP address, enter it directly by pressing the number keys. The * (asterisk--sometimes called a “star” key) is used to enter a “.” (period also called a “dot”.)

When you are entering numbers or letters, the left arrow key performs a backspace, deleting the character to the left of the cursor. The following page contains a breakdown of the features of the remote control.

Using the On-Screen Keyboard

The DVC-1100 uses a keyboard that appears on-screen to enter text into the Setup Wizard screens. When the cursor is located in a setup screen that requires characters to be entered, press the ENTER key to bring up the on-screen keyboard.

The keyboard will only appear if the cursor is located in an area of the screen that allows text or numbers to be entered.

To enter text, use the arrow keys on the remote control to move the cursor to the required character. Press the ENTER key on the remote control to put the character on the screen. Continue entering characters until you have “typed” the characters that are needed.

When you are finished entering text and numbers, move the cursor to highlight

OK on the screen and press ENTER; or alternatively you can press the CANCEL key on the remote to remove the keyboard from the screen, leaving

what you typed on the screen.

The keyboard allows entering any of the following:

• Numbers 0 through 9

• Upper case Letters A through Z and lower case letters a through z

• Special characters: period (.), dash (-), colon (:), at sign (@), space,

backspace (to delete a character to the left), Clear (CLR) to clear the entered text, comma (,) , and a slash (/)

When you are entering letters, the first letter entered is automatically entered as UPPER case. The bottom left “arrow” on the screen is a Shift key. This allows you to change from UPPER to lower case and UPPER case shift lock. The keyboard features “wraparound” capability. If you press repeatedly on the left or right arrow keys, the cursor will wraparound to the letter on the opposite end of the row to speed up moving around the keyboard.

Using the Setup Wizard

The following descriptions of the Setup Wizard screens will help you understand the purpose and procedures for providing the required information.

The Phone number you enter is one you create for family, friends and others to call you over the Internet from another DVC-1100 VideoPhone. You can use your regular phone number or make up a new one. Only your name will be displayed at the other end of the video call. Your phone number will not be visible to anyone else.

Using the Setup Wizard (continued)

Wireless Site Survey Screen

To use your DVC-1100 wirelessly, it is necessary to find an available wireless network. The Wireless Site Survey screen makes this simple. Upon starting, the DVC-1100 performed a “site survey” looking for wireless network devices the DVC-1100 can connect to. These discovered wireless devices are displayed by their SSID name on the Wireless Site Survey screen. On a home network, you may have just one entry. In a business, there may be numerous wireless devices listed.

The Enable Wireless checkbox is checked by default. This allows the DVC-1100 to be used wirelessly. If an Ethernet network cable is used instead, uncheck this checkbox and press Next to continue setup for a wired network as described on page 15.

To setup for wireless operation, use the remote control up/down arrow button to select the SSID of the device you will

Keys

Enter encryption keys in the four boxes by using the remote control number pad or the on-screen keyboard. To connect to an encrypted wireless device, the key you enter in the DVC-1100 must match the key of the wireless device. These keys are entered in hexadecimal format, meaning you can use the numbers 0 through 9 and the letters A through F. The key must be entered as a specific number of characters to be accepted as detailed below:

A 64-bit encryption key must be exactly 10 characters in length. (Example: 12345678FA is a valid string of 10 characters for 64-bit encryption.)

A 128-bit encryption key must be exactly 16 characters in length. (Example: 456FBCDF12340012 is a valid string of 16 characters for 128-bit encryption.)

Using the Setup Wizard (continued)

Wireless Settings Screen (continued)

A 256-bit encryption key must be exactly 58 characters in length. The box for entering a key will scroll to allow entering numbers that do not fit in the box. (Example:12345678901234567890123456789012345678901234567890FFAAABBE is a valid string of 58 characters for 256-bit encryption.)

Only one key needs to be entered. Press the down arrow after entering the first key to enter a second key. Enter another key or press the down arrow to navigate down the screen. Continue for all four Key boxes. When you have entered all the keys needed, press the down arrow and press the Apply button.

The DVC-1100 will attempt to connect to the selected SSID, using the settings on the Wireless Settings screen. If the connection fails (probably due to a

wireless network settings incompatibility) the message Connection Failed appears. You will need to determine what wireless network settings are causing the failed wireless connection. See the Troubleshooting section on page 58 for help.

If the Connection OK message appears, the DVC-1100 has successfully connected to the selected SSID.

Press the OK button to save any changes and return to the Wireless Site Survey screen.

Press Next on the Wireless Site Survey screen to continue.

Using the Setup Wizard (continued)

Network Address Screen

The Network Address screen asks for information that is needed to connect a DVC-1100 call over the Internet. Most home users with a cable or DSL modem can leave the checkbox checked to obtain an IP address automatically.

If you know you cannot be assigned an IP Address automatically through a DHCP server then uncheck the checkbox and enter your IP Address, Subnet mask and

Gateway.

Obtain an IP Address automatically (Default)

The application will attempt to obtain the IP address from the DHCP server. When this is checked, the other settings on this screen are automatically grayed. Also, if this setting is checked, you will skip the DNS screen, described on the next page, as the DNS will be set automatically.

IP Address, Subnet mask, Gateway

If necessary, enter each of these settings for the DVC-1100. You will be able to obtain the IP address, subnet mask and gateway address from your router configuration settings, ISP or network administrator.

Host name (optional):

Your Internet Service provider may require you to provide a host name to connect to the Internet. If this is required you can enter it here. Today, this is rarely required on a broadband connection and this setting is optional.

MAC: xx:xx:xx:xx:xx:xx

MAC (Media Access Control) is a unique identifier for the Ethernet hardware of your DVC-1100. If you need to know the MAC address of your DVC-1100, it can be found on this screen.

Press Next to continue.

Using the Setup Wizard (continued)

DNS (Domain Naming System) Screen

If you entered an IP address in the Network Address screen (described on the previous page) you will see the screen for setting DNS server addresses. The DNS screen asks for information regarding the Domain Name System (DNS) server.

You should be able to get both of these settings from your

router configuration settings, ISP or your network administrator. Only the primary DNS server address is required, though it is best to have both the primary and secondary addresses.

Press Next to continue.

The Domain Name System (DNS) translates Internet domain names (for example www.dlink.com, which is easy for humans to use and remember) to IP Addresses, which are what computers use to find each other on the Internet.

Network Speed Screen

The Network Speed screen asks you to select the type of broadband Internet connection you use. Each choice has default send and receive speeds defined for you. If you need to change these settings after completing the Setup Wizard, this can be done by selecting the Settings > Network > Speed screen.

A message appears asking to restart the DVC-1100 to complete the setup. Press the Yes button to accomplish a restart.

Congratulations! You are now ready to make and receive i2eye VideoPhone calls.

Using a Telephone with the DVC-1100

Although optional, it is recommended that you connect a standard telephone to the DVC-1100 VideoPhone.

The telephone that you use for the DVC-1100 VideoPhone will not be connected to your phone wall jack. You will use the telephone as a means of conducting and receiving calls over the Internet only.

The telephone handset is used to place video calls over the Internet, similar to how you would with a regular phone call. You dial a VideoPhone number to reach a party on the other end of the VideoPhone call. You can speak through the telephone, listen to the other party in privacy, and even switch to the Speakerphone Mode on the DVC-1100 to share the audio with others. This can all be controlled by the remote control. When the phone is picked up, the built-in and external microphones are muted. When you receive a VideoPhone call, the telephone rings.

You can use a cordless phone, a telephone with a speakerphone to replace the built-in microphone to share the call with others and even use a phone recorder to allow recording of an audio message when someone calls your VideoPhone and you are not available.

The DVC-1100 supports dialing methods throughout the world. Please refer to page 24 for details on how to dial local video calls, calls outside of your Area code and calls outside of your Country code.
