10.6 Connector Pinouts

 

 

D-Sub TDIF-1

 

 
The 25 pin D-sub connectors are wired according to TDIF-1, version 1.1:

GND is connected to pins 7, 14, 15, 16, 17, 22, 23, 24, 25. 
 
 

AES/EBU 
 

The XLR connectors are wired according to AES3-1992: 
 
1 = GND (shield) 
2 = Signal 
3 = Signal 
 
AES/EBU and SPDIF are biphase modulated signals, therefore polarity doesn't matter. Pins 2 
and 3 are neither hot nor cold, they carry the same signal. But as AES3 uses a balanced trans-
mission they are inverted in polarity.
