5.4 Transfer Modes: Resolution / Bits per Sample
32 bit, 4 byte (stereo 8 byte)
This format is compatible with 16-bit and 20-bit. Resolutions below 24-bit are handled by the
audio application. The card works internally with 32-bit data, but audio data transfer is limited to
24-bits.

5.5 Power supply

The CardBus card does not provide power to the attached I/O-box. Therefore a hi-tech
switching power supply is included
The PCI card operates as power supply for the attached I/O-box
The Digiface draws a high startup current of more than 2.5 A during initialisation. Current at 12
Volt operating voltage: unloaded 170 mA (2 Watts), loaded 430 mA (5.1 Watts). Supply voltage
range DC 7 V – 38 V, AC 7 V – 27 V.

6. Hardware Installation

6.1 PCI Interface

Before installing the PCI card, please make sure the computer is switched off and the
power cable is disconnected from the mains supply. Inserting or removing a PCI card while
the computer is in operation can cause irreparable damage to both motherboard and card!
1. Disconnect the power cord and all other cables from the computer.
2. Remove the computer's housing. Further information on how to do this can be obtained
from your computer´s instruction manual.
3. Important: Before removing the card from its protective bag, discharge any static in your
body by touching the metal chassis of the PC.
4. Insert the PCI card firmly into a free PCI slot, press and fasten the screw.
5. Replace the computer's housing.
6. Reconnect all cables including the power cord.
7. Connect PCI interface and Digiface using the supplied cable (IEEE1394). This is a standard
Firewire cable (6-pin).

6.2 CardBus Card

Before inserting the CardBus card make sure the complete HDSP system is ready for
operation!
1. Connect the CardBus card with the Digiface using the supplied cable.
2. Insert the CardBus card with the Hammer logo up into a PCMCIA slot.
3. Plug the power jack of the supplied switching power supply into the connector labeled AUX,
on the rear of the Digiface.
4. Connect power cord to power supply, plug into AC outlet. The green LED of the power
supply and the red LED of the Digiface will light up.
5. Switch on the notebook and boot the operating system.
The small 15-pin connector of the CardBus card is coded. Only the supplied special cable
can be plugged in, and only when the metal sleeve is up. Any kind of violence when
plugging in and out can cause damage to the CardBus card.
