Server Backplane Connections

1. Redundant PSU

  • The server will run on just one power supply.  For reliability, it is better to have both powered.

2. GPIO / Tally

  • Two 25 pin D-type connections.
  • One is used for GPIO (used to trigger external devices), and one for Tally (on-air lights on live cameras).
  • GPIO has 12 inputs and 12 Outputs and uses 5v input levels and Open Collector outputs.
  • The Tally has 8 outputs are also all Open Collector.

3. Video I/O connections Located along the top of the back plane, and include:

a) Video Reference Sync inputs (supports both Black and Burst and Tri-Level)

  • If not looping through the reference feed, 75ohm termination is recommended.
 

b) SDI inputs (x8)

  • Supported video standards: 720p50/59.94 and 1080i50/59.94 (HD) /525i59.94 and 625i50 (SD). 
  • 16 Channels of embedded audio are supported on the SDI inputs with a maximum sample rate of 48 KHz and 24bit sampling.
  • At system power up, the SDI inputs are set by default to match the system video format setting.
  • The table below shows system video format versus valid inputs for that format.

System Setting

Valid Inputs

1080@59.54i

1080@59.54i or 525@59.94i

525@59.94i

525@59.94i or 1080@59.54i

720@59.94p

720@59.94p

1080@50i

1080@50i or 625@50i

625@50i

625@50i or 1080@50i

Note:
  • SDI inputs will maintain their format setup even when a cable is removed. 
  • A server restart is required to reset a SDI input back to default or to auto-sense a new signal that has been plugged to an input.
  • Sync SDI inputs will have a two frame latency through the system for interlaced sources and three frames for Progressive feeds. If a source is not sync'd, the Frame Sync setting MUSTbe enabled (in the Properties menu).
  • A non-sync'd source with Frame Sync left disabled will consume processing power and impair the performance of the system

c) HDMI inputs

  • The two HDMI inputs share their resources with two of the SDI inputs.
  • If HDMI is enabled (via the Control Surface menu) one SDI input will be disabled for each HDMI input.
  • HDMI input 1 uses the same resources as SDI input 4.  HDMI input 2 shares with SDI input 6.
  • The system will auto-sense the HDMI input signal (add/drop frames and re-size as required).
  • HDMI inputs are for Video only. Audio and HDCP is not supported.

(d)  SDI Outputs (x4)

These are hard-coded to output Program on output 1, Stage output on 2, AUX1 on output 3 andAUX2 on output 4 and support 16 channels of embedded audio.

4) Analog Audio 

a) XLR Audio Inputs (x2)
  • Designed for line level input (+4dBu). 
  • Microphones will require a pre-amp to bring them up to line level.
  • Selectable in the audio mixer (default = mute).
  • Once un-muted, the system auto-saves the current state (even after re-boot).

b) XLR Audio Outputs (x4)

Hard-coded such that Outputs 1&2 = Program 1&2, and Outputs 3&4 = Stage 1&2.

c) LTC Audio Input

Currently used to display a system clock time on the Multi-viewer output

No features making use of ‘timed events’ are yet enabled

5) Computer Ports 

a) Serial Port

  • (not used)

b) USB Ports (x4)

  • One of the USB ports is to be used with the Multi-view display touch screen (if necessary).
  • Two other USB ports can be used for mouse and keyboard connectivity if necessary when performing maintenance or troubleshooting.

c) Network Interface Connections (x3)

  • The left is NIC 1 and is configured as DHCP by default.
  • NIC 2 on the righti s set to a static IP address of 192.168.100.100.
  • The settings for these two network ports can be changed via the control surface touchpad menus where you can also set the host name for the server.

d) VGA Port

  • VGA port can be used for display if necessary when performing maintenance or troubleshooting.

6) Graphics Board

  • Only the bottom left DVI connection is used for connecting to the Multi-view display.
