6. Hardware Installation

6.1 PCI / PCIe Card

Before installing the card, please make sure the computer is switched off and the power
cable is disconnected from the mains supply. Inserting or removing the card while the com-
puter 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 computer.
4. Insert the PCI card firmly into a free PCI slot, press and fasten the screw. OR: Insert the PCI
Express card firmly into a free PCI Express slot, press and fasten the screw.
5. Replace the computer's housing.
6. Reconnect all cables including the power cord.
7. Connect PCI card and Multiface using the supplied cable (IEEE1394). This is a standard
FireWire cable (6-pin).

6.2 CardBus / ExpressCard

Before inserting the CardBus or ExpressCard make sure the complete HDSP system is ready
for operation!
1. Connect the CardBus / ExpressCard with the Multiface using the supplied cable.
2. Insert the CardBus / ExpressCard into the appropriate slot.
3. Plug the power jack of the supplied switching power supply into the connector labelled AUX,
on the rear of the Multiface.
4. Connect power cord to power supply (if detachable), then plug the power supply into an AC
outlet. The green LED of the power supply and the red LED of the Multiface will light up.
5. Switch on the notebook and boot the operating system.

6.3 Notes on Power Supply

• The CardBus / ExpressCard do not deliver power to the Multiface. Therefore a hi-tech
switching power supply is included.
• The PCI / PCIe card operates as power supply for the Multiface via the FireWire cable. An
external power supply is not required.
The Multiface II draws a high startup current of more than 2 A during initialisation. Current at 12
Volt operating voltage: unloaded 720 mA (8.6 Watts), loaded 1 A (12 Watts). Supply voltage
range DC 8 V – 28 V, AC 8 V – 20 V.
The Multiface II has a higher power consumption than the original Multiface. Therefore the
Multiface II will only work with a HDSP PCI card revision 1.9 or higher!
While the Multiface causes a load of about 9 Watts to the PCI card, the Multiface II will cause a
load of about 12 Watts. The old HDSP PCI cards are not designed for such a load. The voltage
regulator found on the PCI card will switch off after a short time due to overheating. The HDSP
PCI revision 1.9 uses a more powerful regulator.
All PCI Express cards work with the Multiface II.
