Connecting and powering up
The camera back Stagebox is a standalone unit designed to mount on a camera using a V-lock or Anton Bauer mounting plate. Stagebox is shipped with a 12 volt DC power supply with an input voltage range of 100 – 240V at 50/60Hz. Also in the box you will find a copy of the manual, two BNC to DIN 1.0/2.3 patch cables and a WiFi antenna which should be screwed on to the Wifi connection on the top plate. The power switch is located on the bottom plate next to the “12V DC in” XLR connector and is recessed to prevent it being operated accidentaly in use.
- Connect the power supply unit and switch on start booting the Stagebox
- The fan will operate
- The LEDs will sequence
- The tally lights will illuminate
- If conneced, the SDI output will display the Stagebox logo
The boot sequence should take approximately 30 seconds but can take longer after a firmware upgrade. When the boot sequence is completed the Stagebox the tally lights will go off and the LEDs will indicate the current Status. The Stagebox will continue to be displayed until a valid video stream is received.

The pictures below show the Stagebox connections. A detailed description of each connector is given in the technical specification.
The Signal connectors are found together on the side of the Stagebox and are clearly labelled. The SDI connections are brought out on standard BNC connectors, whilst the Genlock and LTC ports use DIN 1.0/2.3. Cable adaptors are provided to convert to BNC if required. The standard Ethernet connector is a wired RJ45 for use with CAT5e/6 cables. However, this port uses a small form factor pluggable (SFP) device which can be replaced with a different SFP having a multi-mode or single mode fibre interface. see SFP Module
Quick Start setups
There are two main ways to set up a Stagebox system
- Source Synchronous
- Stagebox to Stagebox links on Layer 2 or Layer 3 networks
- PTP enabled synchronisation on multicast on Layer 2 networks
As Stagebox looks to IT networking for significant efficiencies in workflows and production chains, multicasting is an obvious technology to exploit. Again a common IT Standard, IGMP v3, this enables a Stagebox to serve its media streams to multiple clients with most efficient use of bandwidth. A media stream is only served to clients who subscribe thus enabling multiple clients the ability to process / monitor streams in much the same way a cross-point router might for video. The added benefit being that all the media elements are served over a single IP network, not a large range of different routing systems (audio / video / timecode / talk back etc…).
