9.2 MADI I/O Daughter Cards - Including version II
The Mykerinos MADI Daughter board is the solution for high I/O channel count applications. It offers 56 channels of 24 bit
bi-directional I/O and up to 64 channels in MADI-X (MADI Extended) format. It can be ordered either in a BNC based
coaxial version or an optical duplex SC version. Both versions are fitted with a standard Wordclock BNC I/O connector,
which can be software programmed as a Wordclock In or Wordclock Out signal. The version II of the MADI daughter
card is now fully multi-board compliant.

9.2.1.1 Coaxial Cable Specifications
Merging has conducted internal tests showing reliable connection of MADI via 75 Ohms coaxial cables over distances up to
250 meters between Merging manufactured products.
The 50 meter length limit specified is a safe minimum assumption as per the original MADI specifications in the AES-10-
1991 original standard.
Therefore, 75 m length should be no problem in a relatively "clean" environment.
