12.2 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.

12.2.1.1 Coaxial Cable Specifications
Merging recommends the use of video grade quality coaxial cables with nominal impedance as close as possible to 75 Ohm.
The 50 meter length limit specified is a safe minimum assumption as per the original MADI specifications in the AES-10-1991
original standard.
However, up to 100 m length should be no problem in a relatively "clean" environment.
