2.2.3. AES/EBU inputs/outputs.
The physical connector used is a DB15 female, with the following pinout:
DB15 connector pinout identification
- Pin 1: AES1_IN+ - Pin 9: AES1_IN-
- Pin 2: AES2_IN+ - Pin 10: AES2_IN-
- Pin 3: N/A - Pin 11: AES1_OUT+
- Pin 4: AES1_OUT- - Pin 12: AES2_OUT+
- Pin 5: AES2_OUT- - Pin 13: N/A
- Pin 6: SYNC_IN_AES+ - Pin 14: SYNC_IN_AES-
- Pin 7: SYNC_OUT_AES+ - Pin 15: SYNC_OUT_AES-
- Pin 8: GND
Considerations:
- The signals containing audio and synchronizing information (Channel 1 and Channel 2)
are compliant with the AES-3 standard. The signals that only contain synchronizing
information (Synchronism) are governed by the AES-11 standard.
- The synchronizing input signal can be used to change the sampling rate of the
AES/EBU output signal (set by default at 48 kHz).
- The synchronizing output signal will either repeat an external synchronizing input signal,
or will take the internal 48 kHz signal to the synchronizing input of other AES/EBU
equipment items. See menu description in section 3.1.3.3.
- When both of the two audio codec channels are used independently of each other, the
audio carried by each of them will be output through the connector corresponding to
channel 1 or 2.
Digital and analog outputs are always simultaneously availables.
2.2.4. GPIO connector.
General Purpose Inputs and Outputs connector. Configurable functionality. For further
information, see section “3.1.8.4. GPIOs configuration” of this manual.
NOTE: - The output signals are open collector active-low.
- The input signals are opto-coupled with internal 2.2Kohms resistor. They are
active-high.
The connector is a DB15 female type, with the following pinout:
DB15 connector pinout identification
- Pin 1: GPO1 - Pin 9: GPO2
- Pin 2: GPO3 - Pin 10: GPO4
- Pin 3: GND - Pin 11: N/A
- Pin 4: N/A - Pin 12: N/A
- Pin 5: N/A - Pin 13: N/A
- Pin 6: GPI1 - Pin 14: GPI2
- Pin 7: GPI3 - Pin 15: GPI4
- Pin 8: GND
