12 Mykerinos/-X 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.
12.1 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.
MassCore multi-board mode compatibility: This mode is available from Pyramix version 6.0 and higher. When running in a
MassCore multi-board system, the ADAT I/O daughter card offers audio in ADAT format ONLY. No SPDIF format is supported.
WARNING! When using the ADAT daughter card in XDTDM mode (from Pyramix version 5.0 and higher) or in MassCore
multi-board mode (from Pyramix version 6.0 and higher) it requires a hardware modification. Without this modification, the
use of the board may result in data loss. Please contact your Merging Technologies Sales Partner to arrange the modification.
The following figure represents the configuration of the Mykerinos bracket when plugged with an ADAT daughter card.
