In total you should only connect 5 tiers of USB hubs together. A tier is defined by the number of hubs a device's signal must pass through before it reaches the host. For example, using the DSB-H4, D-Link's 4-port USB hub, you could connect a theoretical maximum of 341 hubs in five tiers, this would leave you with an incredible 1024 ports to connect USB devices! But you should only connect 127 devices together at any time. Do not add a 6th tier of USB Hubs.

Yes, Kick-off! can be connected to a USB hub, or a USB keyboard, and it will still be able to detect and respond to system crashes. To complete its restart procedure on Macs, Kick-off! also sends the USB "Power On" signal. Most USB hubs cannot pass the USB Power On signal along to the Mac; however, you can ensure the Mac will start itself by setting the "restart automatically after power failure" feature in the Energy Saver Control Panel.

For the HP Advancestack 100Base-T Hub-8txe and the ProCurve Networking by HP 100Base-T Hub 8, which are Class II hubs, plug a straight-through cable from the MDI port on one hub to the MDI-X port on the other hub. For the HP Advancestack 100Base-T Hub-12tx and the HP Advancestack 100Base-T Hub-12txm, which are Class I hubs, only one single repeater is allowed. These hubs, however, can be stacked to allow up to five of these hubs in a stack. See similar questions...

You can connect up to 5 levels of hubs together. For more efficient networks, Hewlett-Packard recommends restricting the levels to 3. See similar questions...

You can connect up to eight 10Base-T Switching Hubs in one stack with included Stacking Cable. You can, using one of the methods described in question 1, connect multiple stacks of 10Base-T Switching Hubs together. See similar questions...

The Switch 208t/224t can connect to a stack of 10Base-T hubs via the 10Base-T connectors and a crossover Category 3 cable as shown in the following illustration. Notice that the Switch 208t/224t provides a dedicated 10-Mbps connection to each 10Base-T hub. The 100TX high-speed ports are used to connect to local servers or the network backbone switch.

A USB cable and the presence of USB connections are not yet adequate for exchanging data successfully. However, data transfer can be effected using a USB cable if a serial COM Port is emulated by the GPS receiver. The GPS data must be available in the NMEA 0183 format when data is called up online, so that Geogrid is in a position to evaluate these data. See similar questions...

To connect two HP Advancestack 100vg Hub-14 (product J2415A) devices together with fiber cable, install HP Advancestack 100vg Fiber Optic Transceivers (product J3027A) in transceiver slot B of the root level hub and in transceiver slot A of the second tier hub. Configure transceiver slot B in the root level hub as "12B" (Downlink). Connect the fiber cable from the transceiver in slot B in the root level hub to the transceiver in slot A in the second tier hub. See similar questions...

No. Quatech USB to serial adapters do not also included hubs. However, you can purchase third-party USB hubs to add additional USB ports to your system. The maximum data rate for USB 1.1 is 12 Mbps. USB 2.0 devices are capable of speeds up to 480 Mbps. Quatech USB 1.1 compatible serial adapters can reach speeds of 460.8 kbps--more than fast enough for most serial peripherals. Thus, there would be no advantage to implementing USB to serial adapters on the USB 2.0 standard. No. See similar questions...

A self-powered hub plugs into an electrical outlet so that it is better able to provide connected devices with power. Only low power USB devices can be connected to a bus-powered hub (like mice and keyboards). A self-powered hub will allow you to safely connect other devices that require up to the full 500mA outlined in the USB specification. D-Link offers self-powered and user-selectable self- or bus-powered hubs. See similar questions...

There are a number of USB bridges on the market. These devices allow a direct connection between 2 PCs via their USB ports. However, D-Link recommends using a DSB-650 to add Ethernet networking via USB. Two computers can be connected either via an Ethernet Hub (DE-805TP/C - the "Hubby" is a great choice for a home network) or via a cross-over cable. USB bridges are limited in their functionality. They effectively work by accessing a shared piece of memory built into the bridge. See similar questions...

This is becoming more of a common problem because a lot of computers are now coming out with just USB connections. The way around this is to either purchase a USB to Serial port converter, or contact the manufacturer of the product to see if they have a USB connection for the instrument. See similar questions...

Yes, the CB-USB4 cable that comes packaged with the camera, is required for downloading images using the camera. The stock number for a replacement cable is (Item #200776). It can be purchased through the Olympus Emporium or by phone at 1-800-201-7766. See similar questions...

To connect 100vg hubs with twisted pair cable, you must use the uplink and downlink ports on the 100vg hubs. The hub that is connected to the server is called the "root level" hub. Hubs connected to the root level hub are called the "second tier" hubs, and hubs connected to the second tier hubs are called the "third tier" hubs, etc. To connect a root level hub to a second tier hub, you connect a cable from a downlink port on the root level hub to an uplink port on the second tier hub. See similar questions...

No. Since 100vg technology uses all 8 wires "straight-through" for high speed transmission, crossover cables cannot be used. Uplink and downlink ports exist on 100vg hubs to allow the hubs to be connected using "straight-through" cables. See similar questions...

Besides twisted-pair, the hubs can handle thin coax and fiber-optic cabling through the optional HP J2608A ThinLAN Transceiver Module and the optional HP J2606A Fiber-Optic Transceiver Module. (The transceiver modules listed above are the same as those used in the previous Advancestack Hubs.) If you require additional connectivity, the HP J2609A AUI Port Module will allow you to connect any type of external transceiver. See similar questions...
