14. Hardware Installation 
USB 
•  Use the power cord to connect the Fireface with any suitable power outlet. 
•  Connect computer and Fireface using the supplied USB cable. 
•  Power on computer and UCX. 
The Mac OS detects the hardware as Fireface (serial number). 
FireWire 
•  Use the power cord to connect the Fireface with any suitable power outlet. 
•  Connect computer and Fireface using a 6-pin FireWire cable (IEEE1394a). In case your 
computer does not have any FireWire port, PCI, PCI Express, CardBus and ExpressCard 
cards can be used to add them. In case your notebook does not have a 6-pin jack, or did 
not include a 6-pin to 4-pin adapter: such adapters are available in your local computer 
store. 
•  Power on computer and UCX. 
Note
: FireWire and USB can be connected at the same time, but it is not recommended. How-
ever, the unit will use only one port. Upon start of the computer the port that becomes active 
first will be used. With no port active the unit searches on both USB and FireWire until it finds 
an active one. 
15. Driver and Firmware 
15.1 Driver Installation 
After the Fireface has been switched on (see 14. Hardware Installation) install the drivers from 
the RME Driver CD. The driver files are located in the folder \Fireface_USB and \Fireface_FW 
on the RME Driver CD. Installation works automatically by a double-click on the file Fireface 
USB.pkg or Fireface.pkg. 
RME recommends downloading the latest driver version from the RME website. If done, the 
procedure is as follows: 
A double-click onto driver_usb_mac.zip expands the archive file to Fireface USB.pkg. Instal-
lation works automatically by a double-click on this file. 
A double-click onto fireface_x86.zip expands the archive file to Fireface.pkg. Installation 
works automatically by a double-click on this file. 
During driver installation the programs Fireface USB Settings and Fireface USB Mixer (To-
talMix FX), or Fireface Settings and Fireface Mixer respectively, are copied to the Applica-
tions folder. It is recommended to link these two programs to the Dock so that they are always 
available. 
Possible reasons why a Fireface is not found automatically: 
•  The USB or FireWire port is not active in the system (check in System Profiler) 
•  The USB or FireWire cable is not, or not correctly inserted into the socket
