User manual HP PAVILION 8900

[. . . ] Deterministic bandwidth allocation guarantees bandwidth for time-sensitive applications, such as real-time video feeds, that could otherwise be disrupted by heavy bus traffic. Devices can be daisy-chained and no central bus supervision is required. The bus is dynamically reconfigured whenever new nodes are added, which means users don't have to configure node IDs or unique termination schemes. Low-cost peripherals can be powered directly from the 1394 cable, so no dedicated power supply is needed. [. . . ] The following message will display: 10. Insert your Windows 98 installation CD into your CD-ROM drive. Select "CD-ROM drive" and click Next. Windows will search the CD for the appropriate driver and list what it finds. After it has identified the appropriate driver, click "Next" to begin installation of the driver. 5 When the dialogue box below appears onscreen, the installation is finished. You will be instructed to reboot your computer. 12. After rebooting, click on the Device Manager tab in System Properties, which you access from the Windows Control Panel. You should see an entry for the driver you installed under the 1394 Bus Controller item. If the driver is not listed, please go back to Step 1 and reinstall the card. The Windows 98 installation CD includes the Texas 1394 OHCI driver, so you do not need an installation CD or diskette. After the installation has finished and the computer has rebooted, you may connect 1394/FireWire devices to it. The first time you hot-plug a 1394 device into one of the host card ports, you will be asked to insert your Windows 98 installation CD. However, you won't need to insert the CD to add additional 1394 devices; they should automatically appear in the Device Manager after they are connected. 6 3 Using the Card This chapter covers a few points on how to use the card once it is installed in your computer system. Connecting Devices There are two ways to connect 1394/FireWire devices to the host card. Devices can connect in serial in a "daisy chain" or through a repeater connected to one of the card ports. Daisy Chain Connections When you connect devices in a daisy chain configuration you can connect up to 63 devices in a row. This scheme is simple and convenient, but has one drawback. Since 1394/FireWire devices are "hot-pluggable, " you can connect and disconnect devices while the computer is turned on. When you disconnect a device, the other devices that come after it are temporarily disconnected until you reconnect them to the chain. The 1394/FireWire card supplies power to devices through the cable connection. See the Power Considerations section later in this chapter for more information. Repeater Connections If you use a 1394/FireWire repeater to connect devices to the card, all connected devices are independent of each other. You can then disconnect any device without disturbing the other devices connected to the card. An additional feature of using a hub is that the repeater can also provide power for devices that use more power than the 1394/FireWire cabling supplies. This allows connecting one or more devices that use more power. 1394 Cabling The 1394 standard has a maximum connection cable length of 4. 5 meters (15 feet). This means this is the maximum distance between devices. [. . . ] Make sure the devices are getting the power they require. If a powered repeater is connected, make sure it is turned on. If the devices are connected in a daisy chain and you have problems after disconnecting a device, please reconnect the device. If not, please restart the computer and see if the problem clears up.
