Page 5: Introduction
KVM EXTENDER/SHARERS 2. Introduction 2.1 General Overview The Keyboard/Video/Mouse (KVM) Extender/Sharers let you either control a computer from a remote keyboard, monitor, and mouse, or share a computer between two users (not at the same time). In Shared Mode, local or remote user control is exercised through a switch on the Host Module of the Extender/Sharer, which is connected directly to the computer. -

Page 10: Operation
CHAPTER 4: Operation 4. Operation Once the computer system is booted, if you’re in the Extended Mode, you’re ready to begin working. NOTE In Shared Mode, always cold-boot the system from the Local setup. If you boot from the Remote Module, the results are unpredictable. When the computer system is booted in the Shared Mode, the local user has the option of remaining connected to the PC or switching control to the remote keyboard, monitor, and mouse. -

Page 12: Types Of Equipment Supported
CHAPTER 4: Operation 4.3 Types of Equipment Supported 4.3.1 K EYBOARDS The Extender/Sharers support all original-equipment keyboards when (1) you operate the Extender/Sharer in Extended Mode (where you control the computer solely from the remote location), or (2) you operate the Extender/Sharer in Shared Mode and use the original keyboard as the local keyboard. - Page 13 KVM EXTENDER/SHARERS NOTE Mouse drivers for software-configurable mice are specialized and might not support other serial mice. So it’s best to use the same type of software-configurable mouse at both locations in Shared Mode. However, many types of nonconfigurable mice are supported by popular mouse drivers, so you might be able to mix a software-configurable mouse with a mouse that doesn’t require configuring.
