The USB 2.0 so you can connect USB 2.0 (4-Port) Hub (IC147A-R2) PC/Server Digital Camera Card Reader Scanner USB Modem OVERVIEW Attaching peripherals to your PCs has never been easier! A single USB 2.0 (4-Port) Hub (IC147A-R2 or IC147AE-R2) allows you to connect up to four Universal Serial Bus (USB) printers, scanners, and other devices to a single PC. The hub has one USB mini Type B upstream and four USB Type A downstream ports. A USB 2.0 Hub, 7-Port (IC148A) lets you attach up to seven USB devices to a PC. This hub has one USB mini Type B female connector and seven USB Type A female connectors. Connect just 4 or up to 127 peripherals! Although the most common application gives your PC access to just four or seven peripherals using one hub, you can also cascade hubs to connect more peripherals. A typical cascaded application could provide a single PC with access to any number of peripherals from one to 127. The first hub in the cascade links to your PC via its upstream USB mini Type B port and the included USB cable. One of the downstream Type A ports on this hub attaches to the upstream mini Type B port on the second hub via the included USB cable. The remaining three Type A ports on the second hub connect to peripherals or additional hubs via USB cable (ordered separately—see the Ordering Information on the next page). Cascading hubs continues in this way up to a maximum of five tiers that provide a total of 127 attached peripherals. Whether or not you are cascading hubs, you don’t even have to open the PC case to install the hub. It’s plug-and-play. The hub complies with the USB 2.0 speeds. Data-transfer speeds vary, depending on which version of USB your equipment is using. USB Version 2.0 equipment specifies a high-speed (480 Mbps) interface. But, to achieve this high speed, the controller card in your PC must be USB 2.0 compliant. In other words, you must have a USB 2.0 compliant PC. The hub works with your older USB equipment. The hub is also backward-compatible with USB 1.1 devices. (If you’re using USB 1.1 devices, the maximum speed you can achieve is 1.5 or 12 Mbps.) Technically Speaking USB 1.1, introduced in 1995, is the original USB standard. It has two data rates: 12 Mbps for devices such as disk drives that need high-speed throughput, and 1.5 Mbps for devices such as joysticks that need much lower bandwidth. In 2002, a newer specification, USB 2.0, High-Speed USB 2.0, gained wide acceptance in the industry. This latest version is both forward- and backward-compatible with USB 1.1. It increases the speed of the peripheral to PC connection from 12 Mbps to 480 Mbps—that’s 40 times faster than USB 1.1! This increase in bandwidth lets you use external peripherals that require high throughput, such as CD/DVD burners, scanners, digital cameras, video equipment, and more. USB 2.0 supports demanding applications where multiple high-speed devices run simultaneously, such as Web publishing. USB 2.0 also supports Windows XP through a Windows update. An even newer USB standard, USB On-The-Go, is also now being deployed. USB OTG enables devices other than a PC to act as a host. It enables portable equipment—such as PDAs, cell phones, digital cameras, and digital music players—to connect to each other without the need for a PC host. USB 2.0 specifies three types of connectors: the A connector, the B connector, and the mini B connector. A fourth type of connector, the mini A (used for smaller peripherals such as mobile phones), was developed as part of the USB OTG specification. 724-746-5500 blackbox.com 2of 3 #10487 3 of 3 8/30/2007 #10487 724-746-5500 blackbox.com TECH SPECS Compliance — FCC Class B, Part 15; Distance (Maximum) 16.7 ft.
