C100 HDS Software Update
New Features
Bla klight (Bulk I/O ard)
Following customer demand for more I/O channels, greater I/O flexibility and more robust RIO redundancy C100 HDS V2
introduces the new Blacklight I/O pipe, a powerful optical audio interconnect that carries four times the capacity of standard
MADI and is designed for secure, fail-safe operation over huge distances.
Each Blacklight mezzanine card holds four Blacklight I/O transceivers providing two permanently configured redundant 256
channel optical I/O channels on four duplex LC connectors. Each Blackrock core can now contain up to two Blacklight
mezzanine cards, two standard 64ch. MADI I/O cards or a combination of the two.
Introduction of the new Blacklight I/O mezzanine card provides the following functionality:
• 256 input channels with full processing from a single, upgraded Blackrock DSP card
• 256ch I/O bandwidth with control and status data between Blackrock and B-RIO, over a single duplex fibre pair
• An automatic ‘split point’ for the division of the maximum Blackrock ‘I/O slot’ limit of 512 bidirectional channels
between the upper and lower mezzanine cards
• An automatic ‘split point’ dividing the I/O slot allocation between the redundant ports on a Blacklight I/O card
according to the I/O cards fitted in each B-RIO
Additionally the V2 Software is compatible with the original C100 HDS 128ch DSP cards, providing various bug fixes and
offering a cost option retrofit for Blacklight I/O cards. A further DSP upgrade is also available as a cost option to allow
access to greater than 128 audio channels.
256 Input Channels from a Single Bla kro k DSP ard
All new C100 HDS consoles shipping from early 2010 will be fitted with the upgraded 256ch DSP card as standard and only
a licence will be required to access the higher channel counts. Full processing is available on all 256chs though Audio delays
remain the same: 64 modules shared between all input channels and ASG buses, each with 5.4s duration.
256 Channels of I/O Bandwidth between Bla kro k and B-RIO
In the current implementation if redundant fibre connections and redundant Blackrock processors are specified the four RIO
MADI ports will all carry the same data (two sets to and from each Blackrock) thus reducing the maximum I/O count to
62chs per RIO. However, with the new Blacklight mezzanine cards fitted in both the Blackrocks and B-RIO the four links
will provide 256chs audio I/O with control and status and full fibre redundancy, so that each Blackrock can have 256ch main
and one 256ch backup I/O link, regardless of the I/O cards fitted in the B-RIO.
Automati I/O Split Point between Mezzanines
The console detects the I/O cards fitted in the B-RIO(s) and allocates enough I/O slots to each mezzanine card, starting with
the lower card and finishing with the upper one.
This applies to B-RIO and MORSE Stage oxes only and not for any other MADI units.
Automati I/O Split Point within Mezzanines
The console detects the I/O cards fitted in the B-RIO(s) and automatically divides the I/O slots allocated to a Blacklight
mezzanine card between the two redundant ports according to the physical I/O cards fitted in the attached B-RIO(s).
This only applies to B-RIO and MORSE Stage oxes. For all other ports the console will assign I/O slots consecutively to the
remaining MADI ports until all availa le slots are used or all MADI ports have een completely included.
