9 Mykerinos Modular I/O Daughter cards
One core feature of Mykerinos’ architecture is to break it into two parts: the portion that plugs into the PCI connector of the
PC and the I/O daughter card that contains the physical connectors to the outside world. This allows for potentially many
system applications without committing the design to any specific I/O configurations.
9.1 ADAT I/O Daughter Card
This I/O daughter card features two sets of Toslink Optical connectors each carrying up to eight channels of 24-bit Audio in
the ADAT compatible format. This provides up to 16 mono channels of input and 16 channels of output up to 48kHz and up
to 8 channels at 96kHz in S/MUX compatible format. One of the sets can be programmed in software to carry SPDIF (or
AES-EBU) formatted signals instead of ADAT. In this mode, total I/O is limited to 2 + 8 = 10 Digital Audio channels.
STANDALONE mode compatibility
: When running in a STANDALONE system, the ADAT I/O daughter card offers 16 I/O
channels in ADAT format and/or 2 I/O stereo channels in SPDIF format (SPDIF and ADAT modes use the same optical
connectors and are consequently exclusive one with the other).
HDTDM multi-board mode compatibility
: When running in a HDTDM multi-board system, the ADAT I/O daughter card
offers audio in ADAT format ONLY.
No SPDIF format is supported.
XDTDM multi-board mode compatibility
: This mode is available from Pyramix version 5.0 and higher. When running in a
XDTDM multi-board system, the ADAT I/O daughter card cannot be used for input and is then only capable of 8 ADAT
outputs via Optical Output A with the same 8 duplicated on Optical Output B.
No SPDIF format is supported.
WARNING
! When using the ADAT daughter card in XDTDM mode (from Pyramix version 5.0 and higher) it
requires a hardware modification before being used in XDTDM mode. Without this modification, the use of the board
may result in data loss. Please contact your Merging Technologies Sales Partner to arrange a mod.
The following figure represents the configuration of the Mykerinos bracket when plugged with an ADAT daughter card.
