The DVI-D Dual Head KVM Extender with Audio and RS232 is ideal for critical applications in which reliable digital image quality and fast switch-over of redundant hardware are required. With operating temperatures from 41 to 113°F (5 to 45 °C) and storage temperatures from -13 to 140°F (-25 to 60 °C), this KVM extender is particularly beneficial in industrial or other harsh environments where sensitive hardware should not be exposed. It is also ideal for work environments in which noise from fans and CPUs is unacceptable. The small form factor fits easily into the workspace, reducing clutter and enabling greater productivity. LEDs on the device provide easy visual status indication. The dual monitor support lets you eliminate tedious switching between applications and to extend a visually complex application across two screens - hundreds of feet from the CPU. The DVI-D dual-monitor KVM extender is easy to install, and ships with all the tools you need for immediate implementation: DVI-D Copper KVM Extender pair (Local Unit + Remote Unit) CPU cables 2x 5V DC universal power supply for the DVI-D Fiber Extenders 2x US type power cords User manual (Quick Setup) 2x DVI-D (1,8m) video cable (DVI-D single link male-to-male) DB9-F, (2) 3.5mm TO DB9-F cable (for RS232 and bi-directional audio) USB (1,8m) cable (USB type A to type B)
