Functional Block Diagram

The MV-825-RTR comprises a video router and a multiviewer which are separate and interconnected functional blocks within the MV-825-RTR unit.
MV-825-RTR = Video Router + MV-8 Core Multiviewer Figure 1-3 shows a functional block diagram of the unit.

Fig. 1-3: MV-825-RTR Functional Block Diagram

The unit essentially contains a 48×48 12G SDI video router, a powerful multiviewer and some flexible internal signal switching. The internal switching is done with separate router crosspoint switches to allow the switching of signals going to the multiviewer and of signals going to rear head display outputs.

Router Crosspoint

The Video Router is implemented with a 60×48 Router crosspoint, which allows 48 router video SDI inputs and 12 internal multiviewer head display signals to be routed to 48 router video SDI outputs.

Router Controller
The crosspoints in the MV-825-RTR each perform a routing function under the control of an internal Router Controller which runs its own software, independent of the multiviewer core.

Multiviewer Core
The Multiviewer is a Grass Valley MV-8 Series Core Multiviewer, (48×12).

Note: For full details about the MV-8 Series Core Multiviewer, see the MV-8 Series Core Multiviewer User Manual, see Related Documents, on page iii.

Multiviewer Input Crosspoint
The 48 router video SDI inputs can also be independently routed to the multiviewer via a 48×48 MV Input crosspoint.

Multiviewer Head Output Crosspoint
The multiviewer generates up to 12 head displays (dependent on licenses installed) which can be independently routed to the 12 multiviewer head display outputs of the MV-825- RTR unit via an MV Head crosspoint; additionally, any of the 48 router video inputs can be also routed out.

Streaming Out of Multiviewer Input-Copies

An MV-825-RTR unit can be ordered with a ‘streaming out input-copies’ license option (MV- 825-H264) or the license can be applied in the field. All MV-825-RTR units support this feature and can be upgraded with this license in the field.
Streaming out is via either the ‘1G1’ or the ‘1G2’ MV control Ethernet interface.
These H.264 video IP streams can be viewed on a desktop PC with appropriate software.

MV-825-RTR Configuration, Control and Monitoring

The MV-825-RTR comprises two functional blocks which run their own software and are configured independently:
• Video router.
• ‘MV-8 series’ core multiviewer block.

These functional blocks are configured, controlled and monitored separately via their own IP addresses and control interfaces. Table 1-2 summarizes the interfaces available and the tool to use.

Table 1-2: MV-825-RTR Control Screen Interfaces

Configuring of the multiviewer’s video walls is also done with the GV Orbit Client tool.

Note: Licensing of the MV-825-RTR unit is done via the Multiviewer block, for the entire unit.

Multiviewer Block

Please refer to: the MV-8 Series Core Multiviewer user manual  for full information about the core multiviewer in the MV-825-RTR. (See Related Documents, on page iii.)

Video Wall Design

Design of the multiviewer video wall used by the MV-825-RTR unit is done with the GV Orbit Client tool. GV Orbit users use the GV Orbit Client as part of a GV Orbit system with a GV Orbit server and all the services and facilities that the system affords. For users who do not have a GV Orbit system, the GV Orbit Client is available in ‘Lite’ form (GV Orbit Lite) as a free-of-charge download.
The layout and style of the MV-825-RTR video walls are designed and designs are stored in a GV Orbit multiviewer project, which is then pushed to a MV-825-RTR’s multiviewer for deployment.
Multiple wall layout designs may be generated and stored. Different wall designs can then be pushed to the multiviewer for various MV-825-RTR multiviewer applications.
See Multiviewer Terminology, on page 235 for a list of multiviewer terminology.

Router Block

The video router within a MV-825-RTR unit contains its own router controller and simply requires:
• An analog reference signal for SMPTE RP-168-2009 compliant switching.
• An Ethernet connection for configuration and control.
Video inputs are routed to router video outputs, switching of routes is timed. The router is controllable via the SW-P-02 and SW-P-08 protocols over IP.
The router also supports the RollCall protocol. Routing can be done with RollCall-capable panels or by using the RollCall Control Panel application.
The router supports 12G video with the ‘MV-825-12G’ license.

Video Reference

The MV-825-RTR auto-detects a bi-level or tri-level analogue reference sync signal and reports the video standard. The video reference is selectable from two external video reference inputs.
There is a reference loop-through output per reference input.
The video reference signal is used as the timing basis for video line switching. Switching is then done independently for each router input (compliant with SMPTE RP-168-2009).
The video standards for the MV-825-RTR reference input signal and for route switching are defined as part of the unit configuration. If there is no reference or no compatible, matching reference, then signal switching timing will crash-switch.

Timed Video Switching

The MV-825-RTR does timed switching to SMPTE RP-168-2009 for video input signals which are compliant with SMPTE RP-168 and which share the same frame rate. The router will switch between inputs on the switching line according to the video switching standard of the signal being switched to.

The video switching standard can be configured separately for each input in an ‘auto’ mode; the best-matching reference available is used. For example, with a 1080i50 analogue reference signal, 1080i50, 1080p50 and 2160p50 signals can be timed-switched.

Note: Two different, independent references:
The MV-825-RTR can accept two different and independent external references. For example, this allows:
• 50Hz video signals to be switched with a 50Hz reference; and also
• 59.94Hz video signals to be switched with a 59.94Hz reference.

IMPORTANT:
• If there is no reference input signal, then the router will crash-switch upon receiving a routing switch command.
• If a video input signal is inconsistent with the configured video switching standard set up for that input, then the signal will be crash-switched.

IMPORTANT:
When using an interlaced reference signal, progressive video sources are only switched on the first field of the reference signal.Router Configuration and Control
MV-825-RTR router block configuration may be done in either of the following ways:
• Via a set of control screens with RollCall Control Panel/GV Orbit Client. 
(See Router Configuration Control Screens, on page 57 and 
see Router Crosspoint Control Screens, on page 87.)
• Via a web page. 
(See Router Config and Control Web Pages, on page 113.)

2. Hardware Description

This section describes the MV-825-RTR unit from the outside and contains information on front panel controls and indicators, and on rear connectors and indicators.

Chassis Overview

The MV-825-RTR is a 2RU 19” rack-mount chassis with connectors at the rear (see Figure 2-1).

The chassis is air-cooled and the airflow is front-to-back. The unit has a door at the front with a grille and integral cooling fans. On the rear, there are two power inlets and an array of video, control and data signal connectors. Some rear connections use small form-factor pluggable (SFP) plug- in modules. There are two dual-redundant power supply units (PSUs) in the chassis which are removable from the rear.

WARNING: Optical Outputs

With some SFP module types fitted, the MV-825-RTR may be equipped with optical input/outputs which contain low-power laser beams.

• Do not look into an optical output. Laser radiation can cause irreversible and permanent damage of eyesight.
• Do not look at the end of a fiber to see if light is coming out. Use optical instrumentation.
• Unused optical outputs should be covered, to prevent direct exposure to the laser beam.

For chassis physical dimensions, see Appendix B Unit Dimensions , on page 199.

Chassis Front

The front door has two knurled fastening screws and a grille, behind which are fitted four fans which draw air in at the front, see Figure 2-2.

With the front door open, some inner card status LEDs are visible: However, there is normally no reason to open the front door.

The front door is not normally opened. When it is opened, it drops down, hinged along the bottom. To open:
1 Unscrew the two captive knurled door fasteners, see Figure 2-2.
2 Pull the door outwards about 2 cm and then down. 
The door hinges along its bottom edge. See Figure 2-3. 
When the door is open, the door fans and the fan supply wires are visible along with the front main module (which is not a serviceable item).

To Close the Front Door

Before closing the door:
1 Check that the fan supply wires are all connected to the front edge of the MV-825-RTR main card. See Figure 2-4.

To close the door:

2 Pull the door upwards into a vertical position (the door hinges along its bottom edge) and then push it fully into the front of the chassis.
3 Secure the door by tightening the two captive knurled door fasteners.
Keep the front door closed when the equipment is powered, to maintain cooling airflow.

CAUTION: Close the Door:
Always keep the MV-825-RTR front door closed. This ensures correct ventilation and operation of the equipment.
The integral door fans ensure cooling airflow through the MV-825-RTR chassis when the door is properly closed.
When the front door is open, there is no cooling airflow through the frame. Do not leave the door open for longer than 45 seconds.

Front Indicators

There are no external front indicators.
Internally, with the front door open and dropped down, the front edge of the front main module can be seen in the top half of the chassis frame. This is the MV-825-RTR main card, see Figure 2-5.

Note: The front main module is not a serviceable item.

CAUTION
Close the front door when the equipment is powered, to maintain  cooling airflow.
The front door should not need to be opened in normal operation. And the MV-825-RTR main card is not a serviceable item.

LED status indicators are on the front edge of the front main card within the MV-825-RTR chassis and are viewed by opening the front door. Figure 2-6 shows the front edge of the card and Table 2-1 lists the LED color codes for the MV-825-RTR main card.
Along the underside of the card are four header connectors. These supply power for the front door fans. See Figure 2-6. The front door’s fan supply wires connect to the four small headers on the underside of the front of the card.

Other DIP switches and connectors along the front edge are for engineering use only:
• DIP switches – The four DIP switches are not used. Check that all four switches are in the “up” position.
• Engineering connectors – There are two other connectors on the front edge of the card, see Figure 2-6. These are for Engineering use only and should not be used.

Rear Connectors

HD BNC Video Inputs
The video inputs form sources for the router.

Connector Label and LED

The positioning of the rear video BNC connector’s label and its corresponding Catsii LED is shown in Figure 2-10. Basically, the label is to the left of the connector, as seen from the rear of the unit, and the corresponding Catsii LED indicator is above or below the BNC connector.

Note: This ‘Label-BNC-LED’ positioning arrangement applies both to the video input and to the video output BNC connectors.

HD BNC Video Outputs

The video outputs are destinations for the router.

Catsii LEDs

The Catsii LEDs are on the rear panel at each router video input or output HD- BNC connector. These indicate the presence of a signal and its video standard. The colors used can be set up by the user on the router configuration web page, see Catsii Colors Page, on page 119. Table 2-3 shows the default colors.

BNC Reference Connectors

The reference input is used for SDI video input timing and display output timing. There are two analog reference inputs and two “loop-through” outputs on MV-825-RTR.
The reference inputs are unterminated. Termination should be done at the reference output connector with a 75 ohm termination, or the reference signal may be “looped through”, via the Reference Out connector, and taken to another piece of equipment (where the signal must be terminated, at the end of the loop).

AC Mains Inlets

The IEC power inlets are the mains disconnection devices for this unit. Each power supply unit (PSU) has a status LED. See Table 2-4.

Multiviewer Head Display Outputs

Display outputs 1 to 12 come from Video SFPs fitted into the 6x SFP cage positions. The SFPs fitted depend on which display output options have been purchased.

Different types of video SFP modules provide:
• 2x SDI Coax outputs per SFP; or
• 2x SDI Fiber outputs per SFP; or
• 1x HDMI output per SFP.
SFP blanking plugs must be fitted if no SFP is present.

Each display output has an associated LED which indicates the output status. See Table 2-5.

Environmental Considerations

The ambient temperature for all the supplied equipment should not exceed the limits specified in MV-825-RTR Specification, on page 189.
Installing the equipment in a clean environment with moderate temperature and humidity will promote a long and trouble-free equipment life.

Chassis Dimensions

See:
• Appendix A Overall Dimensions, on page 189.
• Appendix B Unit Dimensions, on page 199 for a chassis dimension drawing.

Chassis Ventilation

The MV-825-RTR is a 2RU 19” rack-mount chassis with front-to-back air cooling. Cooling fans are mounted in the chassis front door. Additionally, each PSU module has an internal variable-speed cooling fan.

Figure 3-1 shows the external chassis air flow and air intake and exhaust holes. Figure 3-2 shows the internal chassis air flow.

CAUTION:
Do not block the MV-825-RTR chassis air intake and exhaust holes. This permits correct unit operation.

Cooling Fan Failure

Depending on the length of time the MV-825-RTR has been run with no fan the unit may need to be returned for checking and repair. Contact Grass Valley or your Grass Valley dealer to discuss the situation

Rack Mounting

Location in Rack
The MV-825-RTR is designed to be installed in a standard 483mm (19 inch) equipment rack for use. The unit requires a 2RU high space within a rack.

The following precautions should be observed:
1. Do not obstruct the front air intake holes. These are to allow the inlet of cooling air.and the air exhaust holes at the sides and rear of the unit.

CAUTION:
Do not obstruct the front air inlet holes.

2. Do not obstruct the air exhaust holes at the sides and rear of the unit.

CAUTION:
Do not obstruct the side and rear air exhaust holes.

3. Ensure that there is a minimum clearance at the rear of the mainframe of 200mm (8 inches). This is ESSENTIAL.

CAUTION:
Ensure a minimum clearance at the rear of the chassis frame of 200mm (8 inches).

Mounting the MV-825-RTR into a Rack

CAUTION:
The MV-825-RTR unit is heavy (see Weight, on page 189) and will require two people to lift into position, using correct lifting procedures. If you are unsure of the lifting procedures, ask a Health and Safety adviser for information.

Preliminaries
1 Check that the rack is rigid enough for the MV-825-RTR chassis.
2 Use a suitable rack tray in the rack to take the weight of the MV-825-RTR. 
The chassis rear will become heavier when cables are connected.

Note:
If the rack tray has sides, make sure that they do not block the ventilation holes on the sides of the MV-825-RTR.

Fitting the Unit
1 Position the MV-825-RTR in the rack on the shelf. 
Use the correct lifting procedures.
2 Open the MV-825-RTR front door (see Chapter 2 To Open the Front Door, on page 15).
Four chassis rack mounting holes are revealed, two on each side. See Figure 3-3.

3. Secure the MV-825-RTR chassis in the rack at each mounting hole using 4x M6 (1/4 inch) screws. See Figure 3-4. (Screws are available from rack suppliers.)

4. Close and secure the front door (see Chapter 2 To Open the Front Door, on page 15).

Cabling Up in a Rack

When connecting cables to the MV-825-RTR, it is recommended that cable supports are used (clamps and bars) to relieve the strain on rear connectors.
See Chapter 2 Rear Connectors, on page 23.
Cable connection examples for the MV-825-RTR are shown in Figure 3-5.

When the unit powers up, it goes through its booting up sequence and display as splash screen. See Booting Up, on page 42.
Initial network connections should be made to a laptop PC until IP addresses etc are set up, see Initial Connection and Configuration, on page 44.

Powering

WARNING:
To reduce the risk of electric shock, plug each power supply cord into separate branch circuits employing separate service grounds.

Power consumption is listed in Appendix A Power, on page 189.

Note:
Output disruption and MV-825-RTR starting up:
While the MV-825-RTR unit starts up or restarts, there may be disruption to the video outputs. This is normal:
• Routing – The unit starts by routing ‘1 to 1’ inputs to outputs and only adopts the last known routing settings once the control software has successfully started up.
• Licensed features – These do not take effect until the multiviewer software has started up. 
For example, 12G will not be passed until the 12G licensed is set up in the MV-825-RTR unit by the started-up multiviewer software

When the unit powers up, it goes through its booting up sequence and display as splash screen. See Booting Up, on page 42.

Booting Up

The MV-825-RTR boots up after power is applied or after a system reset (for example, from a its control screen).
Booting takes about 1 to 2 minutes to complete. Approximately 1 minute after starting to boot up, each of the head display outputs presents a gray start-up splash screen from the multiviewer within the MV-825-RTR. See Figure 3-6.
Fig. 3-6: MV-825-RTR Start-up Splash Screen Example (Multiviewer)
When the MV-825-RTR has finished starting up, the start-up splash screen goes away and is replaced by the video wall content of the multiviewer project running on the MV-825-RTR.
The unit has booted up.

License Serial Number
Use the serial number shown on the start-up splash screen (Snnnnnnnn) when adding licenses to the MV-825-RTR unit. (See Maintenance – Software, on page 183, for more information.)
Note: Initially, the first few lines of text appear on the splash screen, followed by the remaining lines.
