Description
A wide range of add-on boards with video and serial interfaces are available for the Link AV system. The AV system is the core system in the Link product family, and provides video and serial lines over a single fibre, as well as diagnostics interface for the other products in the family.
The AV system is designed to be modular and flexible, by using a combination of motherboard and daughter boards to provide different signal interfaces. An AV board has 6 on board analogue video channels and extension connectors for up to 4 daughter boards with additional video and data channels.
Currently, daughter boards are available with:
• 2 additional channels of Analogue Video
• RS-232, 115 kbps 12 isolated channels
• RS-485 Half duplex, 115 kbps, 12 isolated channels
• 4 Tritech ArcNet channels
• RS-232, RS-485, trigger, 9 channels
In addition, custom extension boards can be developed.
The daughter boards can be combined so that they work as media converters; i.e. a topside RS232 board can communicate with a remote RS485-board, providing “on-the-fly” media conversion from RS232 to RS485.
The design is based on Innova’s long experience with remotely operated vehicle systems and provides a wide range of features, including;
• All serial channels are galvanic isolated
• All video channels are fully AC coupled
• Pressure tolerant electronics
