3.2. BC2202. AES/EBU digital inputs/outputs module.
General description.
The BC2202 board can manage eight TDM IN bus time-slots to insert four AES3 (or SPDIF)
digital stereo signals into the system, and eight TDM OUT bus time-slots to extract four AES3
(or SPDIF) digital stereo signals from the system.
This board is inserted into the rear part of the BC2000DF rack.
Panel description.
'HW ERROR' red LED*: this LED will turn on when the
system starts and, depending on its status, it will indicate
during normal operation:
-
Configured and active board: fast blinking.
-
Not configured board: slow blinking.
-
Board start error: LED on and fixed.
-
Board configured in backup mode: LED off.
'1' RJ45 type connector: 4 AES3 format digital
stereophonic inputs. Each input has an SRC that enables
automatic adjustment of different AES/EBU signal formats.
'2'
RJ45 type connector: 4 AES3 format digital
stereophonic outputs. The default format is 48 kHz and
24 bits. Each output has an SRC that enables adjustment
by software of the delivered AES/EBU signal sampling rate.
'3' RJ45 type connector: 4 independent inputs
configurable as general purpose inputs (GPI).
'4' RJ45 type connector: 4 independent outputs
configurable as general purpose outputs (GPO).
*
This operation way of 'HW ERROR' LED is valid for 4.06 microcontroller
module firmware version (and later versions).
