Netfinity 5000 - Universal Serial Bus Ports

Applicable to: World-Wide

Universal Serial Bus Ports
The universal serial bus (USB) is an emerging serial interface standard for telephony and multimedia devices. Each USB port is a single connector for devices that previously used serial, parallel, keyboard, mouse, and game ports. USB technology uses Plug and Play technology to determine which type of device has been attached to the connector. Each USB device is accessed by a unique USB address. A device called a hub is used to convert a single USB connector into multiple attachment points. A hub has multiple ports where peripherals can be attached. USB provides 12 megabits-per-second (Mbps) bandwidth with a maximum of 63 peripherals and a maximum signal distance of five meters (16 feet 4.9 inches) per segment.

Note If more than one USB device is to be attached, the devices must be connected to a hub. Your Netfinity 5000 does not support a keyboard attached to the system USB port.

Your Netfinity 5000 comes with two USB ports. Table 13 shows the pin-number assignments for the USB port connectors.
