There are two pinout standards for off-the-shelf AES d-sub cables, Yamaha and Tascam standard.
The Alpha-Link MADI-SX AES uses the Yamaha AES standard. It is generally compatible with Yamaha, Mackie, Akai, and Apogee.
MADI-SX is not compatible with the Tascam AES standard (Avid, Digidesign, Universal Audio, RME, PreSonus).
Consult your equipment manual for their specific pinout requirements.
The AES pinout of the LIVE and LIVE-R follow the Tascam standard.
The Alpha-Link installation guide features the pinout tables.
Some adapters can be found to connect devices with different standards. The Mogami Gold AES YTD DB25 to DB25 is one such example.
