Zboard™ User Guide

USB Hub
The Zboard™ is equipped with a BUS powered USB 1.1 connector that supports fast data
transfer and has two additional USB ports for easy connectivity to USB devices directly with
the keyboard.
This hub supports low voltage devices (up to 100mA) such as a mouse, joystick and so on.
Plugging a high voltage device (such as a video camera or scanner) will result in a
Microsoft® Windows® message such as ‘‘The (name of device) is connected to a hub that
doesn’t have enough power available to support it’’. To fix the problem, plug the relevant
device directly into the computer’s USB port.
USB is the solution for any PC user who has ever dreamed about an instant, no-hassle way to
connect USB devices to their computer.
LED Indicators
In addition to the LED indicators you would find on a traditional keyboard for Caps Lock, Scroll
Lock and Num Lock, the Zboard™ has three LEDs to support some of its unique functions,
including an Enabled LED (which indicates the Zboard™ Keyset is working properly when the
application is active --- see ‘‘Enabled LED’’), and Pad and Bar LEDs to indicate when the
functions in those areas are active.
