QUICK START GUIDE
N2424A 4K Keyboard and Mouse Decoder
Overview
The SVSI NMX-DEC-N2424A Decoder features keyboard and mouse
extension over IP, output scaling, serial, balanced audio, HDMI video
connection, and Power-over-Ethernet (PoE+).
The N2424A Decoder accepts HD over IP streams and converts them back to
synchronized audio and video to allow any video source to any display.
Basic Installation Guidelines
Establishing Connection
N2424A devices are shipped with DHCP as their default IP mode. The IP
address is assigned automatically based on the network DHCP server. If no
DHCP server is found, the unit will use Auto IP mode instead (with a default
IP address of 169.254.xxx.xxx).
Before using your N2424A unit, it must be configured using the free N-Able
device management software. However, you will not be able to configure
units until they are in the same subnet as the host computer. The sample
steps below show how the required changes (to the host computer’s IP
settings) are made in a Windows environment.
Steps for IP address configuration (for Windows 8):
1. From the Control Panel > Network and Internet dialog box, select
Network and Sharing Center.
2. Select Change adapter settings.
3. Select the wired interface connected to your AV network.
4. Click the Properties button.
5. Scroll down in the list to the Internet Protocol Version 4 (TCP/IPv4)
option. Highlight it and click the Properties button.
6. Enable the Use the following IP address option, and enter the static IP
address provided to you by your network administrator.
NOTE: If the computer does not need Internet access, you can simply enter a
unique 169.254.xxx.xxx IP address with a 255.255.0.0 Subnet mask. Please
contact your network administrator if you are unsure of how to configure the
existing interface. If the computer has a statically-assigned IP address, click
on the Advanced button. Then click Add to enter a unique 169.254.xxx.xxx
address with a subnet of 255.255.0.0.
Steps for auto discovering devices on the network:
1. Use the host computer to download and install the latest version of N-
Able:
PC version - http://www.amx.com/products/N-ABLE-PC.asp
Mac version - http://www.amx.com/products/N-ABLE-MAC.asp
2. Attach your N2424A unit(s) to the layer-3 network switch.
3. Disable the wireless adapter on your computer (it must be hard-wired
to the switch).
4. Connect the host computer to the layer-3 network switch.
5. Open the N-Able application.
If all devices do not appear automatically, click the Auto Discover button on
the Unit Management tab. This issues a broadcast command that will
discover all units even if they are not in the same IP subnet.
Logging in Using N-Able Software
Once the host IP address is configured properly, you can view all discovered
units using the N-Able software. Access the N2424A units from the following
tabs:
•Unit Management tab - N2400 Decoder is listed in the Type field.
•Video Matrix tab - N2424A units are found on the N2400 sub-tab of
this screen.
Double-click the unit’s name (in one of the lists mentioned above) to view its
control page. If prompted, enter admin and password for the default
username and password. Once logged in, you can change the username and
password (using the options on the unit’s Settings page).
NOTE: If you would like for N-Able to support auto-login to your units, make
sure N-Able’s Device Auto-login settings match the unit’s username and
password (by selecting N-Able > Settings from the N-Able tool bar).
NOTE: N2424A units force HTTPS connections, so your web browser may give
you a security warning. N-Able on Windows will ask you to download OpenSSL
for Windows to connect HTTPS.

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
FIG. 3).
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.

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.
