The most common usage is the DB25, using TASCAM's pinout (now standardised in AES59 by the Audio Engineering Society [1]). To avoid the possibility of bent pins on fixed equipment, the male connector is generally fitted to the cabling and the female connector to the equipment. The DD50 connector usage is described in AES-2id. [2]
