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 |
- 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
- 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.
