ADDENDUM: VS-81DVI-R
This addendum outlines three changes to the VS-81DVI-R user manual:
First change:
On page 5, Table 2, item 3 is replaced as follows:
3 SELECTED INPUT 7-segment Display Displays the selected input that is currently switched to
the output
1
Second change:
On page 15, before section 7, a new section is added “6.4 Acquiring the
EDID”, which includes the following text:
To acquire the EDID, do the following:
1. Turn the POWER off.
2. Press both the PANEL LOCK button and the INPUT SELECTOR 8 button at
the same time while turning the POWER on again.
The front panel display initially shows a blinking “E” followed by the input
numbers from 1 to 8 that blink, until the unit has completed reading the EDID.
While the machine is acquiring the EDID, do not press any button and do not
turn the power off
3. Release the PANEL LOCK button and the INPUT 8 button.
If an output was connected, the output EDID is read at each input. If an output
was not connected, the default EDID is read at each input.
The default EDID settings are:
Max. resolution – 1600x1200; Max. frequency – 60Hz.
Third change:

3 Overview
The VS-81DVI-R is a technologically advanced, high quality 8x1 switcher for
DVI-D signals supporting the DDWG DVI 1.0 standard.
With a bandwidth of 1.65GHz, the VS-81DVI-R can switch signals having
resolutions up to UXGA, including all HDTV formats. Since high-resolution DVI
signals are very sensitive to cable quality and to PCB layout, the VS-81DVI-R
uses a carefully designed PCB, which includes all buffering, conditioning and
amplifying circuitry to provide a reclocked top-notch output signal.
In addition the VS-81DVI-R:
 Includes DVI-I connectors to make it compatible with all types of DVI cables
 Features 8 input selector buttons, which automatically light up when the unit
detects an active signal on those inputs.
 Includes a built-in reclocking block that regenerates the DVI signal, so
that several units may be cascaded
 Automatically reads and stores, in non-volatile memory, the EDID
1
block
of the display device
 Does not support HDCP (High Definition Digital Content Protection)
 Includes a MUTE button to disconnect the output and a PANEL LOCK
button to prevent unwanted tampering with the buttons on the front panel
 Fits in one vertical space of a standard 19” professional rack enclosure
Control the VS-81DVI-R using the front panel buttons, or remotely via:
 RS-232 serial commands transmitted by a touch screen system, PC, or
other serial controller
 The Kramer infra-red remote control transmitter
 The ETHERNET
To achieve the best performance:
 Connect only good quality connection cables, thus avoiding interference,
deterioration in signal quality due to poor matching, and elevated noise
levels (often associated with low quality cables)
 Avoid interference from neighboring electrical appliances that may
adversely influence signal quality and position your Kramer VS-81DVI-R
away from moisture, excessive sunlight and dust

3.1 Terminology Used in this User Manual
Table 1 defines some terms that are used in this user manual.
Table 1: Terminology Used in this User Manual
Term Definition
802.3 The standard specification for ETHERNET that is maintained by the Institute of Electrical
and Electronics Engineers (IEEE).
Dynamic Host
Configuration
Protocol (DHCP)
Allows the network administrator to distribute IP addresses from a central point and
automatically send a new IP address when an Ethernet point is plugged into a different
network location
Gateway A network position serving as an entry to another network. On the Internet, a node or
stopping point can be either a gateway node or a host (end-point) node.
IP Address A 32-binary digit number that identifies each sender or receiver (within a network via a
particular server or workstation) of data (HTML pages or e-mails) that is sent in packets
across the Internet. Every device connected to an IP network must have a unique IP
address. This address is used to reference the specific unit.
Local Area Network
(LAN)
Computers sharing a common communications line or wireless link, which often share a
server within a defined geographic area.
Media Access
Control (MAC)
Address
A computer's unique hardware number (or address) in a LAN or other network. On an
Ethernet LAN, the (MAC) address is identical to the Ethernet address.
Transmission
Control
Protocol/Internet
Protocol (TCP/IP)
The basic communication language or protocol of the Internet that breaks the message
into appropriately sized packets for the network, and can be used as a communications
protocol in an intranet or an extranet.

Installing the VS-81DVI-R on a Rack

5 Installing the VS-81DVI-R on a Rack
This section describes what to do before installing on a rack and how to rack
mount.
Before Installing on a Rack
Before installing on a rack, be sure that the environment is
within the recommended range:
Operating temperature range +5 to +45 Deg. Centigrade
Operating humidity range 5 to 65 % RHL, non-condensing
Storage temperature range -20 to +70 Deg. Centigrade
Storage humidity range 5 to 95% RHL, non-condensing
CAUTION!!
When installing on a 19" rack, avoid hazards by taking care
that:
1 It is located within the recommended environmental
conditions, as the operating ambient temperature of a
closed or multi unit rack assembly may exceed the room
ambient temperature.
2 Once rack mounted, enough air will still flow around the
machine.
3 The machine is placed straight in the correct horizontal
position.
4 You do not overload the circuit(s). When connecting the
machine to the supply circuit, overloading the circuits
might have a detrimental effect on overcurrent
protection and supply wiring. Refer to the appropriate
nameplate ratings for information. For example, for fuse
replacement, see the value printed on the product label.
5 The machine is earthed (grounded) in a reliable way
and is connected only to an electricity socket with
grounding. Pay particular attention to supply
connections other than direct connections to the branch
circuit (for example, the use of power strips), and that
you use only the power cord that is supplied with the
machine.
How to Rack Mount
To rack-mount the machine:
1 Attach both ear brackets to the
machine. To do so, remove the
screws from each side of the
machine (3 on each side), and
replace those screws through
the ear brackets.
2 Place the ears of the machine
against the rack rails, and
insert the proper screws (not
provided) through each of the
four holes in the rack ears.
Note that:
In some models, the front panel
may feature built-in rack ears
Detachable rack ears can be
removed for desktop use
Always mount the machine in the
rack before you attach any cables or
connect the machine to the power
If you are using a Kramer rack
adapter kit (for a machine that is not
19"), see the Rack Adapters user
manual for installation instructions

:
1. Connect up to 8 DVI sources (for example, DVI computer graphics sources)
to the INPUT connectors.
2. Connect the OUTPUT connector to the DVI acceptor (for example, a DVI
display).
3. If required, connect a PC and/or controller to the RS-232 port (see section 6.1)
and/or the ETHERNET port (see section 6.2).
4. Connect the power connector to the mains electricity.
After turning on the power, press an INPUT SELECTOR button (1 to 8) to
choose which DVI input to route to the output
