Sierra Video Introduction 1 Chapter The compact Sm-xx series multi-viewer enables up to 8, 12, or 16 (depending on model) channels of video to be viewed on a single display device. There are auto-sensing inputs for composite video, SDI and HD-SDI. In addition there is provision for component RGB/YUV or S-Video and two DVI-I video inputs. Up to 3G 1080p is supported.
Sierra Video Each scaler on the video card processes one of the possible inputs (CVBS, SDI/HD-SDI, DVI, etc) and scales it to the desired tile size for the selected position on the output. A mixer on each video card combines all the video tiles and sends the resulting image to the CPU card. The final display output comprises all of the tiles in a single picture.
SM-XX Powerful Alarms Alarms may be created for video sync loss, black (loss of luminance), freeze-frame, embedded audio loss, external audio loss, over level, out of phase (of chosen pairs), teletext loss, and closed caption loss. The colors used for on-screen alarms are as follows; Audio loss: Yellow- posistion (left or right) indicates channel. Audio Over: Yellow- posistion (left or right) indicates channel.
Sierra Video Using GPI I/O Assignable GPI I/O with 16 inputs and 8 outputs for external alarm indication and tally functions. Bargraph Scales The following audio scales are supported: Colors used for the upper and lower ranges of each bar type can be customized to satisfy any in-house monitoring style for each of the six scale types.
Sierra Video Operation 2 Chapter Introduction The front panel user interface comprises a power switch, and 6 buttons for configuring the unit, 10 illuminated pre-set configuration buttons, a USB-2 interface and LED indicators for status reporting. For text insertion and additional functionality, a PC keyboard may be connected to the USB-2 socket. An optional 1U remote panel (SV-Remote) replicates the front panel of the SM-xx and is connected via LAN.
Sierra Video Configuration Mode To enter the configuration mode from normal mode (with the red Lock LED off) hold the Lock button down for about 3 seconds. The configuration or ‘menu’ mode will be entered, an on-screen menu will appear and the red Lock LED will illuminate. If the Lock button is depressed again, any changed settings will be saved and the unit will return to normal. The currently loaded firmware version will be indicated at the top of the on-screen menu.
SM-XX Using the Web Interface The QUAD multi-viewer is controlled via a browser using web pages hosted by the frame itself. Note that Java must first be installed on the PC or MAC that is to be used. This is available as a free download from: http://www.java.com/en/download/manual.jsp Note: The default IP Adress is 192.168.0.120 To access the web interface, type the IP Address configured for the frame into a browser and the Java application should launch immediately.
Sierra Video The web interface comprises three areas, the Object and Source Explorer, the Editor Workspace and the Display Preview. Tile objects can be one of six basic types; None, Video, Audio, Text, Logo and Clock. The color of the tile as it appears in the Editor Workspace and Display Preview indicates the currently set object type, as listed in the table below. Object Type None Video Audio Text Logo Clock Tile Color Grey Blue Green Brown Red Black Operation is designed to be simple and intuitive.
SM-XX Object and Source Explorer The Objects folder contains the list of current objects and each object’s given name. The currently selected object is highlighted. The Sources folder contains the list of video and audio sources, with an indication of the source type. Those sources that are currently assigned to an object appear in red, whereas those that are currently unassigned to an object appear in black. A source that is assigned to the currently selected tile / object appears in yellow.
Sierra Video Navigating the User Interface Settings for multi-viewer objects can be accessed from the Module, Layout, Group and Object menus, or by using the buttons on the toolbar. Main Menus Module Menu The Module Menu allows a module's global settings to be configured. Note: Some functions are only available from the toolbar.

Sierra Video Installation 3 Chapter Introduction The Sm-xx 1U frame may be installed in 19 inch bays with 426mm depth (~450mm including connectors). Ventilation is produced in each frame with exhaust fans on the left hand side (viewed from front) and intake grilles at the right. Frames should be installed into bays such that airflow through these apertures is not impeded. Note: The front rack ears are intended to provide a means of retaining the unit in the rack.
Sierra Video Health and Safety Considerations For your own Protection, observe the following safety precautions when installing, operating and servicing your device. The unit MUST BE DISCONNECTED & ISOLATED FROM THE MAINS INPUT and from other product outputs before undertaking maintenance. ELECTRIC SHOCK HAZARDS exist if conductive instruments, neck chains or fingers etc. are placed within the unit or in close proximity of the input/output terminals/connectors.
SM-XX Connector I/O The SM-xx uses coaxial BNCs for the video inputs, LTC and sync inputs. Microcross connectors are fitted for the two DVI-I inputs and one output. The GPI I/O connector is a high density 26 way female 'D' connector. External audio connections (input or output) are via a pair of female 37 way ‘D’ connectors, with audio monitoring outputs on a male 25 way 'D’ connector. The serial port comprises a 9 way female 'D' connector.
Sierra Video Serial Port Assignments There is a single serial data port that can be configured for either RS232 or RS422 operation. The mode of operation is set by means of jumpers (J13 and J14) on the CPU board. The pin assignment of the connector is shown on page 57. Jumpers J1, J13 and J14 are located on the Controller (CPU) card. Access requires the removal of the CPU card from the front of the unit with the power removed.
SM-XX Audio I/O Connector Pin Assignments AES/EBU inputs or outputs (depending on the card fitted) may be jumper selected per channel to be either balanced or unbalanced. The settings are set via jumpers on each digital audio input card.
Sierra Video Remote Panel The remote panel may be installed in 19 inch bays with 114mm depth (~140mm including connectors) and has the same control functions as the main frame.
