Basic KVM Setup
The N2424A Decoders are KVM-capable when used in conjunction with an
N2412A Encoder. By default, USB connections are enabled and configured
to follow video switching. Follow these steps for basic KVM setup. To learn
about some of the more advanced KVM capabilities, see the section
Advanced KVM Setup (with added security features)
1.
On the N2412A Encoder, connect the USB Mini-B port (designated by a
laptop icon) to the computer to be controlled.
2.
Connect the computer’s video output to the Encoder’s
HDMI IN
port.
3.
On the N2424A Decoder, connect the
HDMI OUT
to the display.
4.
Connect a USB keyboard and mouse to the Decoder’s USB Standard-A
ports (they can be plugged into either port).
NOTE: For wireless devices, simply plug the wireless signal receivers into
these ports. For keyboard and mouse combos (with a single connection)
use the keyboard port.
5.
Using N-Able, click the
Unit Management
tab.
6.
Click the
Auto Discover
button to discover your new devices (if you
have not already done so).
7.
Once discovery is complete (and you see the new units listed in N-Able),
click the
Video Matrix
tab.
8.
On the matrix, click the common cell for the desired Encoder/Decoder
streaming combination. See the screen shot below for an example.
9.
Click the
Take
button to make the change to your matrix. The radio
button turns green to indicate the connection was successful.
Video/USB Switching Options
USB Follows Video
: By default, units can be switched using N-Able without
modifying the configuration. When you switch video streams (using the
matrix as shown above) the USB functionality will follow the video.
Independent USB Switching:
Use N-Able’s
USB Matrix
tab to switch USB
control (without affecting video).
Independent Video Switching:
To switch video streams
without
affecting
USB control, first select
N-Able > Settings
from N-Able’s main menu. When
the
N-Able Settings
dialog box is displayed, disable the
USB follows Video
switching for KVM units
. Now you can use the
Video Matrix
to switch video
streams only.
Advanced KVM Functionality:
To have the ability to use some features,
KVM
Advanced Settings
must be enabled on the individual unit (select
KVM
from
the top of the unit’s web interface). The next section discusses these
settings in more detail.
Advanced KVM Setup (with added security features)
You can configure devices for more advanced KVM operation on the Encoder
and Decoder
KVM
pages. To access these pages, double-click the unit’s name
in the matrix and click
KVM
at the top of the unit’s configuration page (see
Warning! You must assign KVM passwords to your Encoders and Decoders (as well as
change the default login password from admin/password) in order for your system to
be secure.
FIG. 3
SELECTING THE KVM PAGE
NOTE: Many of these options are easier to manage in N-Able’s KVM Wizard
(especially in large configurations). Select Tools > KVM Wizard from the N-Able
main menu to access the wizard.
The following table describes some of the more advanced functionality. It is
important to note that many of these options only appear on the
KVM
page
when
USB
is enabled as well as
KVM Advanced Settings
.
Troubleshooting Guidelines
Please contact technical support at [email protected] or

Options
Descriptions
Permission Levels
Determines which Decoders can communicate with
which Encoders. A Decoder must have a permission
level that is
equal to or greater than
the Encoder in
order for communication to be successful.
KVM Encoders table
Use the
KVM Encoders
table (on the Decoder’s
KVM
page) to:
• Let the Decoder know the Encoder passwords it needs
to establish communication.
• Add/remove Encoders from the Decoder’s list.
Passwords
By default, KVM streams are encrypted with a common
password. You can change the password on the
Settings
page of the Encoder. If you change Encoder
passwords, you will need to supply the new information
to the Decoders to allow communication to continue.
A Decoder only receives password information for the
Encoders on the network that have been associated
with that Decoder as mentioned previously.
Import and export KVM CSV
files
Multiple Encoders and Decoders can be configured from
a single CSV file (which is generated using the
KVM
Wizard
in
N-Able
). Once all changes are made, upload
the file to each unit using its
KVM
page.Click the
Choose File
button, browse to the
CSV
file you exported
from the wizard, and click the
Upload
button.
Problem
Possible Solution
Video is not
transmitting.
• Verify that the Encoder
TX Enable
setting is turned on.
(Encoders ship from the factory with their video output turned
off by default.)
Local Play
graphic is
displayed.
• Verify Decoder is assigned to view a valid stream in the N-Able
matrix.
• Verify Decoder is currently in live play mode (black text on matrix
view).
• Verify network is properly configured and set up. If needed,
connect Encoder directly to Decoder to verify network issues.
Host Play
graphic is
displayed.
• Verify Encoder is in live play mode (black text in matrix).
• Verify source is attached and is outputting a valid signal (
HDMI
LED on Encoder is on).
Unsupported
Resolution
graphic is
displayed.
• Change source resolution to a valid resolution (try 720p60).
• Verify cabling is correct.
Copy Protected
Content
screen is
displayed.
• Contact SVSI technical support.
Black screen/no
graphic is displayed.
• Set Decoder to local play. If the local play graphic does not
appear, check the display input settings and cabling.
• If local play appears, set Decoder to live play and verify network
is configured properly.
No audio is detected.
• If there is no audio on all
Decoders, verify audio settings are
correct on Encoder.
• If there is no audio on a single Decoder, verify audio settings are
correct on Decoder.
