The DL-Vision(M/S) series
The KVM extenders of the DL-Vision(M/S) series consist of a computer module and a
user module.
The computer to be operated and an optionalconsole are connected to the computer
module (DL-Vision-CPU). The remote console is connected to the user module
(DL-Vision-CON).
Both computer module and user module are connected via two fibre optics. These
fibres transmit keyboard, mouse and digital video signals of the connected computer
and enable the user to operate the computer remotely.
The computer can be operated either at the remoteconsole of the user module or at
the local console of the computer module.
Available device variants
The DL-Vision(M/S) series provides various devices that enable the transmission of
additional signals and the usage of several monitors:
NOTE: When applying a DL-Vision multi-channel and/or USB variant, any addi-
tional signals are transmitted via further fibre optics.

Getting started
12 · G&D DL-Vision(M/S)
Getting started
After the KVM extenders have been properly installed, they can be immediately put
into operation.
Mind the following activation sequence while initiating the extenders:
1. Switch on the user module DL-Vision-CON.
2. Switch on the computer module DL-Vision-CPU.
3. Switch on the computer that is connected to the computer module.
Start-up
After the computer and user module has been switched on, the LEDs on the front
panel indicate the module’s operating status.
More information on this topic is given in the chapter Status displays on page 43 ff.
On-screen display at user module
The starting screen of the user module displays additional information about the start-
up, the firmware versions, and the IDs of the connected modules.
The user module stops the start-up and shows a message if no keyboard is connected
to the user module.
NOTE: The recommended activation sequence for the initiation ensures that the
KVM extender is able to read out the features of the connected monitor and to
transmit them to the computer (see DDC transmission with cache function on page 40).
NOTE: To start the module without keyboard, disable the keyboard support of the
user module (see page 38).

Initial configuration of the network settings

Operation
G&D DL-Vision(M/S) · 15
Operation
The computer connected to the computer module DL-Vision-CPU can be operated at
the remote console of the user module and at the local console of the computer
module.
After the start-up, both consoles can operate the computer.
Concurrent operation of the KVM extender
If a user carries out inputs with either keyboard or mouse, the KVM extender auto
locks the input devices of the competing console. The lock is lifted if no inputs are
made at the active console during the adjusted timing of the automatic input lock
(default: 1 second).
After the automatic input lock has been lifted, both consoles are again able to oper-
ate the computer.
As an alternative to operate the computer concurrently through the consoles, the
exclusive operation (see page 16) can be activated.
Related topics:
Changing the time span of the input lock on page 28
Changing the console video mode on page 30
NOTE: The monitors of the remote and the local console of the KVM extender
always display the same image at the same time.
The paragraph Changing the console video mode on page 30 explains how this setting
can be changed.

Operation
16 · G&D DL-Vision(M/S)
Exclusive operation of the KVM extender
Activate the right for permanent access to operate the KVM extender exclusively
with one console.
If this function is active, the extender’s exclusive operation can be activated by press-
ing the hotkey Hotkey+Print (default: Ctrl+Print).
After having pressed this key combination, the input devices of the competing con-
sole are deactivated. By pressing the key combination again at the console where the
permanent input lock has been activated, users at both consoles are again able to
operate the KVM extender.
Related topics:
Right for permanent console access on page 29
Changing the console video mode on page 30
Changing the »Permanent Access« key on page 27
NOTE: After the exclusive operation of the KVM extender has been activated at
one console, the Caps Lock, Num and Scroll Lock LEDs are blinking alternately at
the keyboard of the locked console.
The blinking Scroll Lock LED at the active console indicates the exclusive opera-
tion of the KVM extender.
ADVICE: In the standard configuration of the KVM extender, the computer’s
video signal is output at the active and the competing console monitor.
If necessary, change the videomodes of the user modules (see page 30) to switch
off the image of the competing console while operating the extender at the other
console.
