Page 4: Introduction
Introduction Model 2444 is a 4x4 matrix (crosspoint) switch designed to operate with SDI signals from 125 Mbps to 2.97 Gbps. It supports SMPTE 259M(C) (SD-SDI), 292M (HD-SDI), and 424M (3G-SDI) serial digital video standards. The switch allows connecting any of the four inputs to any of the four outputs. -
Page 5: Front Panel Interface
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. - Page 6 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. The brightness of the LED displays can be adjusted via the Web page interface. It is preserved across power cycles until changed.

Page 7: Network Interface
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. Those settings, along with some other, can be modified using a Web page interface. The unit has to be powered up and connected to the LAN using an Ethernet patch cable, Cat5 or better. -
Page 8: Step 2 - Set Up A Permanent Ip Address
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. -
Page 9: Http Server
HTTP Server The HTTP 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. -
Page 10: Switch Configuration Page
Switch configuration page Fig.4. Switch configuration page. The 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. -

Page 13: Telnet Server
The Telnet server allows 2 sessions: one through Ethernet port, and one through the serial port. Although the sessions are independent, it is not recommended to use both simultaneously. Telnet commands Below is the list of telnet commands supported by the 2444. help Syntax: help lists all available commands;... - Page 14 Syntax: ssw <out> <in> Connect matrix switch output out (1-4) to input in (1-4). Syntax: gsw <out> Get the input connected to output out (1-4). Returns 1-4. Syntax: gcd <in> Get carrier detection status for input in. Returns 1 for carrier detected, 0 otherwise.
- Page 15 Syntax: gla <in> Get launch amplitude value for selected input in. Returns 0 (default), 1 (+50%) or 2 (+100%). sbri Syntax: sbri <val> Sets the front panel LED brightness to value val (0-7), with 0 being off, 7 being the brightest. gbri Syntax: gbri...

Page 16: Serial Communication Interface
The serial interface supports the set of commands identical to that of the Ethernet telnet server. It is possible to communicate to the 2444 using a terminal program (for example, Hyperterminal in Windows). To achieve the look and feel similar to that of a telnet session it is recommended to configure the terminal program to add LF (Line Feed) characters to CR (Carriage Return) characters and to echo input characters. -
