STORA 2
2 HD + 2HD return, 1 G/L, 8 audio, IP, 2 RS, 2 GPIO PLUS 2 free optical links
Overview
The STORA 2 is a very rugged optical fiber transmission intended to connect 2 outdoor cameras to the OB VAN. Its capacity allows two standard cameras or one 3D camera per system.
The equipment assumes transmission of a comprehensive set of signals as follows:
- 2 HD signals (live image),
- 2 HD return path signals (view finder),
- 1 Genlock (PAL image / Black burst / Tri-level),
- 8 analog audio for intercom or broadcasting,
- 1 Ethernet 10/100Mbs,
- 2 Data RS 232/422/485,
- 2 Contact closure.
The transmission board and its power supply are integrated in a compact die cast aluminum box. The enclosure ensures excellent shock/drop protection along with dust and water resistant capacity.
A small internal fan guarantees convection cooling inside of the box with the aluminum walls acting as a heat sink.
All the signals are transmitted on 2 singlemode fibers. Camera side module; STORA 2 RX can be remote powered through Hybrid cable. STORA 2 offers also the access to two free optical fibers, through SC/APC optical connections.
Connectors / Status LEDs
Standard rugged connectors are used for all the signals. HD and PAL video ports are on BNC connectors.
The other connectors are Neutrik D series socket, 4 audio are routed to XLR and the 4 remaining are located on D SUB 25 socket expansion connector for space consideration. IP, RSxxx and contact closure are dispatched on RJ45.
Optical and remote power access is done through a Neutrik OpticalCon DUO socket.
Seven status Led are located on the connector face (details in specification description).
