ServSwitch DKM DVI-D KVM Matrix Switch
One switch that does it all — four modes of switching, plus extension over CATx or fiber.
Virtually instantaneous switching and the
transmission of high-quality DVI-D signals are what
make the Black Box
®
ServSwitch
™
DKM switching
system a milestone in innovative KVM switching.
Certain modes of the single-head KVM switch-
ing support a transparent serial interface at up to
19 kbps and a hardware handshaking. Use it to
control a single device requiring a full hardware
handshaking or up to three devices without hand-
shaking. In dual-head mode, devices
support TxD
and RxD only, with no hardware handshaking.
The ServSwitch DKM features hotkey controls
and an on-screen display (OSD). Use the OSD
to
name connected devices and configure the sys-
tem. A front-panel display with remote control is
also available. Switching can be done remotely via
the RS-232 serial interface or the TCP/IP interface.
For ultimate plug-and-play support,
ServSwitch DKM has DDC read capability to
receive true EDID information from the attached
displays. The digital ServSwitch DKM does not
need skew compensation like analog KVM switch-
es do; the maximum video resolution
is supported
over the full distance.
Setup and Operation Modes
You can configure the ServSwitch DKM DVI-D
KVM Switch in several ways. Connect the switch
to CATx or fiber cabling, which then connects to
the CPU/server with a local transmitter and, on
the other side, connects to a receiver at the USB
keyboard/mouse/monitors (user stations).
Matrix (crosspoint) switching
The DKM switch can be configured as 32 input
to 16 output ports; or in reverse mode as 16
inputs to 32 outputs. Transmitters are installed at
each of the CPUs, and DVI-D, serial, and audio sig-
nals go up to 10 kilometers depending on the
cabling used. Control the switch with
the serial
(RS-232) port or via the built-in Web interface. The
matrix switch mode is especially ideal for post pro-
duction and digital signage applications.
KVM switch
The DKM switch operates as a KVM switch in
three configurations: 16 users to 32 CPUs
(single-
head); 8 users to 16 CPUs (dual-head); and 4 users
to 8 CPUs (quad-head). When used as a KVM
switch, the DKM is cascadable: single-head, up to
1024 ports from one monitor; dual-head, up to
256 ports from two monitors; quad-head, up to
64 ports from four monitors.
Share Mode
Share Mode enables more than one user to
have access to the same CPU at the same
time.
This is ideal in classrooms or conference rooms
where an instructor or presenter wants to use a
laptop and a projector. It also gives an IT adminis-
trator access to a user’s monitor for
troubleshoot-
ing or applying updates.
Additionally, the KVM switch enables port
locking, meaning you can partner ports and
ensure they switch in tandem. This way, when you
switch CPUs, monitors being used in Share Mode
follow automatically.
Control Room Mode
You can connect the KVM switch to servers
and monitors. The OSD enables the
user to switch
monitors between CPUs, and the hotkeys enable
the user to switch between one keyboard/mouse
for all the monitors. You can select from the list of
available CPUs,
and the users don’t need to know
the CPU’s IP address to use the keyboard/mouse.
Users can use Share Mode in this configuration
also, giving access to more than one user at the
same time.
Student/Teacher System
One of the modes that truly sets DKM above
the rest, the Student/Teacher system has two con-
figurations:
Up to 15 students: By connecting the student
workstations with twisted-pair CATx cable,
the
teacher can monitor each student’s work at his/
her station. Additionally, the teacher can display to
any of the student monitors, or share any of the
workstation monitors with each CPU.
Up to 31 students: The student workstations
are connected by single-strand CATx cable,
enabling each CPU to be displayed at one
monitor
(including a large display monitor).
In this configu-
ration, too, the teacher can monitor each student
at his/her station.
