Introduction
Model 2444 is a 4x4 matrix (crosspoint) switch designed to operate with SDI signals
from 125 Mbps to 2.97 Gbps. It supports SMP E 259M(C) (SD-SDI), 292M (HD-SDI), and
424M (3G-SDI) serial digital video standards. he switch allows connecting any of the
four inputs to any of the four outputs. Embedded audio is passed along with the video
signal.
Control of the switch is performed with the front panel button interface or using
Ethernet or a serial communications link (RS-422/RS-485). A Web page interface is
available for easy control and configuration of the switch. he same functionality is
available via a simple command line interface over Ethernet ( elnet) or serial
communications link.
LED displays on the front panel provide indication of current connections and input
carrier detect status.
Network settings (IP address, ports) can be changed via the Web page interface to
accommodate various network configurations.
All settings, including the last switch configuration, are stored in non-volatile memory
and restored after power up.

Front panel interface
Model 2444 has 4 SDI inputs (numbered 1 through 4) and 4 SDI outputs (numbered 1
through 4). All of those are brought out using BNC connectors on the back panel of the
unit (Fig.1).
Fig.1. Model 2444, back panel.
he front panel interface (Fig.2) consists of 4 seven-segment LED displays and 5 buttons.
Fig.2. Model 2444, front panel.
LED displays reflect the inputs currently connected to the corresponding outputs
(labeled above the displays). he decimal points of the LED displays light up if the
signal is detected at the currently selected input.
Connection for a specific output is changed using the following simple procedure:
1. Press Select button corresponding to the desired output momentarily. he
displayed number increments and starts blinking. Keep pressing the button until
the desired input number is displayed.
2. Press and release Set button. he new settings take effect and the display stops
blinking.
If Set button is not pressed within 5 seconds from the last Select button press, the display
will revert to the previous setting and no changes will be made.
5
It is possible to switch more than one output with one press of the Set button. For that
use multiple Select buttons within 5 seconds from the last press.
he brightness of the LED displays can be adjusted via the Web page interface. It is
preserved across power cycles until changed.

Network Interface
Network setup
Each model 2444 unit is assigned a static IP address. As shipped from the factory the IP
address is set to 192.168.24.44, with the netmask of 255.255.0.0. hose settings,
along with some other, can be modified using a Web page interface. he unit has to be
powered up and connected to the LAN using an Ethernet patch cable, Cat5 or better. If
connecting directly to the computer, use a crossover cable, otherwise use a standard
patch cable.
Depending on the network restrictions one or two steps may be necessary. If the
network used to configure the unit can not access 192.168.x.x IP address range, start
with Step 1, otherwise go directly to Step 2.
Step 1 – Set up a temporary IP address
his step is only necessary if the network used to configure the unit can not access the
default IP address (192.168.24.44). In this case the unit must be switched into the
Configuration Mode which allows setting up a temporary IP address accessible from the
current network. he temporary IP address should be selected such that it is:
1) accessible on the network;
2) is not already used by any other device on the same network.
Once the unit is accessible using a temporary IP address, the standard Web page
procedure (Step 2) can be used to set up the desired permanent IP address and other
settings.
o switch the unit into the Configuration Mode, power it up while holding the Set
button on the front panel pressed. he LEDs will display the word “CONF” and the
front panel buttons will not be functional.
Once the unit is in the Configuration Mode run ARP on the computer that is connected
to the same network with the following command line:
arp -s <temporary_address> 08-00-56-ff-ff-ff
Example:
arp -s 10.135.1.61 08-00-56-ff-ff-ff
In Windows either navigate to Start/Run and type the command line in the “Open” box,
or start a Command Prompt window and type the command line followed by Enter.
In Linux type the command line in the terminal window at the shell prompt followed by
Enter. Please use colon characters (:) instead of dashes (-) in MAC address in Linux.
Note: it is recommended to use a temporary IP address that is different from the target
permanent address to be assigned to the unit.
7
Proceed to step 2 without cycling the power (while the unit is still in configuration
mode).
Step 2 – Set up a permanent IP address
Connect to the unit with a Web browser by typing the unit's temporary IP address in the
address box.
Examples:
http://192.168.24.24/network.htm
or
http://10.135.1.61/network.htm
he the network configuration page (Fig.5) will be displayed.
ype in the desired permanent IP address and subnet mask values into corresponding
fields. Click on the Set button and wait for the page to reload. Click on Reboot button.
he unit will reboot with a new IP address, so the current browser session will
disconnect. o continue configuration, type in the new, permanent address in the
address box.
8
HTTP Server
he H P server (Web page interface) makes it possible to control and configure model
2444 using a computer connected to the network and a browser program.
Control page
Fig.3. Control page.
Control page allows changing the matrix switch connections and LED brightness.
o change the connections select the desired input for each of the outputs by using radio
buttons and click on the corresponding Set button. he changes in the connections are
immediately reflected on the front panel LEDs.
o change the LED brightness select one of the 8 levels with a list box and click on the
corresponding Set button. he brightness levels vary from 0 (off) to 7 (brightest).
9
Switch configuration page
Fig.4. Switch configuration page.
he page allows configuring input equalizers for each of the four inputs of the switch.
Extended 3G mode – turning this mode on (checking the corresponding check box) will
provide extra 10 m of cable reach at 2.97 Gbps. However with this setting on, the cable
reach will be reduced for lower bitrates.
Launch amplitude adjustment – this setting compensates for up to 6 dB signal attenuation
at the input.
