For Neutrino-D and Uno-D Series with AES/EBU digital audio, the original TASCAM protocol is used.

The pinout details are as follows:

You may notice that the AES/EBU pinout scheme follows the analog one closely. The original AES/EBU pinout was indeed based on the analog pinout, but using the rst four balanced lines for AES/EBU in, and the last four balanced lines for AES/EBU out. 

While analog breakout cables will often work for AES/EBU connection, note that AES/EBU DB-25 to DB-25 connections require a different pinout in the cable. Analog cables wire pin 1 to pin 1. AES/EBU must ip the connections so that pins 12, 24 and 25 will wind up on the other end of the cable at pins 6, 18 and 19 respectively. (Digital out must feed digital in). 



TASCAM developed the standard for multi-pin DB-25 cables over 10 years ago, and most of the pro audio industry has followed this standard.
