1. Specifications

CHAPTER 2: Introduction

The Computertop TV-III card is a full-motion video display card with a television tuner and audioprocessing circuitry. It allows a live video window from cable or broadcast television to be merged with VGA graphics on a single display monitor. An external image source from a video cassette recorder (VCR), laser disk player, or camcorder is also supported. The Computertop TV-III contains an oncard audio power amplifier sufficient to drive headphones or a set of unpowered external speakers. The Card and an AT®compatible computer running Windows™3.1 and an external VGA display make up a full-motion multimedia presentation system.

The Computertop TV-III card gives you simultaneous viewing of one live television source in a window and running application programs such as spreadsheets, word processors, or desktop publishing in other windows. The hardware requires minimal processor bandwidth, so programs run at full speed even while the live-motion window is displayed.

You can use the system hard disk to store snapshots of live images on the screen. Once saved, the images can be imported into a variety of desktop-publishing or imageprocessing programs for further manipulation.

2. Introduction

COMPUTERTOP TV-III

Use the hardware installation guide that came with your system to find specifics related to your PC.

WARNING

Static discharge can damage sensitive electronic components on your Computertop TV-III card and in your PC. When accessing PC cards, use anti-static techniques: Avoid wearing synthetic fibers and scuffing on the carpet. Dry air and carpeting are ideal for static generation. Before handling PC boards, touch the metal surface of the computer (if it is plugged in) to discharge any residual static. To avoid generating additional static, try standing in one place and having all the tools nearby before installing the card.

3.1 Hardware Installation

Follow these steps to install your Computertop TV-III card:

1.Turn off the power to the PC and the monitor. Disconnect the power cord from the outlet.

2.Remove the cover of the PC.

3.Identify the VGA display section.

This is where the VGA monitor is connected— often a half height card.

4.Find an empty 16-bit slot next to the VGA card. Rearrange existing cards if needed.

5.Avoid static discharge—touch the metal surface of the PC.

6.Remove the metal back plate from the empty slot and set the retaining screw aside. Carefully remove the Computertop TV-III card from the anti-static bag and install it in the empty 16-bit slot next to the VGA card. Make sure the card seats firmly into both connectors of the backplane and aligns with the front edge guide. Use the retaining screw to secure the card to the PC chassis.

7.Attach the “feature connector” cable between the Computertop TV-III board and the VGA display card. Motherboard VGA systems have a dual-row header. Most separate VGA cards have an edge connector. Align the red stripe of the cable to face the rear card edge of the machine. Dress the cable to allow a clean installation of the PC chassis cover.

8.Disconnect the VGA monitor cable from the VGA controller card and reattach the VGA cable to the middle connector on the Computertop TV-III card.

3. Installation

9.Plugthe terminating “dummy plug” into the external connector of the VGA card to which the monitor cable was previously attached.

10.Attach the supplied mini-DIN cable to the Computertop TV-III board.

The yellow jack is for composite video input. The red jack is for left-channel audio input. The white jack is for right-channel audio input.

11.Attach the antenna or cable source to the F-RCA adapter. Screw the adapter onto the cable and insert it in the second hole from the top on back of the Computertop TV-III card. The cable should push in firmly and will stick out slightly from the Computertop TV-III card.

12.Attach the headphone or external speakers to the miniheadphone jack, the top most connector on the card.

13.With the cover off, plug the power cord in and turn on the VGA monitor and the computer. A familiar bootup sequence should be visible on the monitor (a power-up test, or memory count). If everything appears to be normal, proceed with the software installation. If a sequence of beeps is heard or the monitor remains blank, power off the PC. Check the cards and cables for proper

alignment, seating, and installation. Review the initial installation procedures. Compare your setup to the installation picture. Try again.

NOTE

Some Local-bus VGA boards may cause improper operation of the Computertop TV-III board. If you have a Local-bus VGA board in your system and nothing appears on the VGA monitor when you boot up after installing the Com-putertop TV-III board, power-down the system and replace the Local-bus VGA board with any AT bus VGA board. Your system should now boot up and operate normally with the Computer-top TV-III board installed.

3.2 Software Installation

Follow these steps to install the Computertop TV-III software:

1.Proper operation of the Computertop TV-III board requires Microsoft®Windows 3.1 operating system software to run Computertop TV-III software. If you do not have Microsoft Windows 3.1 installed, follow your user manual and install Microsoft Windows.
