3.9.Power Requirements

3.9.1. The video routing and video output modules of the video matrix shall contain no voltages above +12V

DC for Health and Safety reasons.

3.9.2. The video matrix system PSU modules shall have a universal mains input I.E. (99VAC to 264VAC

50Hz)

3.9.3. The video matrix system PSU modules shall provide +12VDC and –12VDC.

3.9.4. The video matrix system PSU modules shall be switched mode type, which are significantly more

efficient than linear PSU’s.

3.9.5. The video matrix system shall be extremely power efficient. I.E. a video matrix system with 256 video

inputs and 128 video outputs shall require less than 200W.

3.10.Physical Size

3.10.1. The design of the video matrix shall be extremely compact and make efficient use of cubicle space.

3.10.2. The video matrix system shall fit into a cubicle of 600mm maximum depth.

3.10.3. The video matrix shall achieve or better the ratio of 3,276 X-points per 1U size.

3.10.4. The video matrix shall achieve or better the ratio of 1024 inputs x 128 outputs in 43U cubicle.

3.11.Third Party Control

3.11.1. The video matrix system shall support a high level Interface by third party control systems.

3.11.2. The third party control interface shall be a RS232 serial port.

3.11.3. The third party control port shall support fast X-point switching I.E. from the start of transmission of

data from a third party controller the video matrix will complete a X-point switch command in less than

50ms.

3.11.4. It shall be possible for multiple third party controllers to control the video matrix system

simultaneously.

3.12.Video Matrix Functions

3.12.1. The video matrix shall support monitor blanking I.E. video outputs can be switched off to display a

black screen.

3.12.2. The video matrix shall support ‘power-up restore’ I.E. the video matrix will power-up and restore all

X-points to their state prior to power-down.

3.12.3. The video matrix shall support zonal switching I.E. multiple X-point switches via single command.

3.13.Fault Tolerance and Redundancy

3.13.1. The video matrix shall be fault tolerant and employ a high level of redundancy in its design.

3.13.2. Each video matrix module shall have its own dedicated PSU module.

3.14.Serviceability and Maintenance

3.14.1. All service and maintenance access to the video routing and video output modules shall be via the

front panels only.

3.14.2. The video matrix system modules shall be on line serviceable I.E. it is possible to remove and

replace modules without the need to power the system down or take it off line.

3.14.3. It shall be possible to interchange modules within a system by only having to reconfigure them.

3.14.4. It shall be possible to replace any sub-module within a module in under 20 minutes.

3.14.5. It shall be possible to completely restore a video matrix module or system’s configuration using

removable and a software configuration tool provided by the manufacturer.
