6-62 D21m Modules Date printed: 30.08.07
6.8 Discontinued Components (not available for new systems)
6.8.1 HD Card 1.949.410
Please note that this card has been replaced by the D21m HD card S (
see
chapter 6.5.1) and is not available for new systems.
The D21m HD card provides the link to the DSP core systems. Each input and
output can handle up to 96 channels in each supported sampling frequency (in
combination with the Performa core, the number of I/O channels is restricted
to 48). The system clock used is taken from the host DSP system, so no extra
synchronization is needed.
The card detects all other I/O cards that are inserted into the D21m system
and displays their presence on the front panel of the frame. Once all audio
interface cards are plugged in, pressing the RECONFIG key on the front panel
con rms the con guration to the system. Then all cards are activated and
their audio signals are fed into the HD link.
Host link interface cable type CAT-5 UTP Cable
Cable length up to 10 m
Connector RJ-45
Capacity of one CAT-5 connection 96 channels
Current consumption (3.3 V) approx. 600 mA

LEDs: On if a valid signal is present at the input that is locked to the system clock.
Jumpers: When using the Performa core, only 48 channels can be transmitted from the
core to the D21m system. In order not to lose audio data, the channel selector
of the HD Card has to be con gured to this mode by a jumper on the card.
The other two jumpers have to remain in their default positions and must not
be changed.
