KVM Extender: Single vs Dual Access Options

KVM Extender: Single Access and Dual Access Options
ET 350 Monitor and ET 355 Monitor HL
What is the KVM extender?
The KVM (keyboard, video, and mouse) extender allows a 3M Dynapro ET 350 Monitor or ET 355 Monitor HL to
function from a location up to 1000 feet (300 meters) from the host computer.
The KVM extender has two main parts:
Remote unit: Built into the housing of ET 350/ET 355 monitors that are ordered with a KVM extender option.
Local unit: Connected to (and near to) the host computer.
Single Access and Dual Access
There are two types of KVM extender options: Single Access and Dual Access.
Single Access
The local unit of the Single Access KVM extender has connectors for the following components:
Serial connector
CAT5 interconnecting cable (to connect the KVM extender’s local and remote units)

KVM Extender: Single Access and Dual Access Options
Dual Access
The Dual Access KVM extender offers even greater flexibility than the Single Access option. Like the Single Access
option, the ET 350/ET 355 monitor can be up to 1000 feet away from the host computer.
The Dual Access option is different from the Single Access option in the following two ways:
More connections are possible. The local unit has three more connectors than the KVM Single Access option.
The host computer can be operated from either local or remote stations.
A Dual Access scenario
In the scenario illustrated in Figure 2, a standard monitor (along with a mouse and keyboard) is attached to the host
computer. This makes it possible to operate the host computer from either the ET 350/ET 355 monitor or from the
host computer’s location. With a Single Access KVM extender, the host computer could be accessed only from the
ET 350/ET 355 monitor.
