The ASTRA Series backlit keyboard with numeric keyboard features an elegant, slim line black keyboard with low-profile scissor-switch keys for a light, yet responsive feel. With five selectable light levels, the ASTRA is the perfect choice for any lighting environment. The keyboard features two USB 2.0 ports to enable you to connect e.g. your mouse, contour shuttle or a USB-dongle. The ASTRA keyboard is developed with two USB cables. One for the keyboard itself, and one for the USB hub, at the back of the keyboard. The reason for having a separate cable for the USB hub, is to avoid problems with installations, that require a KVM extender.
