STORA 1
2 HD + 2HD return, 1 G/L, 8 audio, IP, 2 RS, 2 GPIO
Overview
The STORA 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 RX can be remote powered through Hybrid cable.
Connectivity
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).
