MacOS: PowerPC running MacOS 8.6 or better, and a USB port. Any Macintosh computer with one or more USB ports running Mac O/S 8.6 or later (the US-224 has not been tested with Mac O/S X as of this writing. Please check the website for updates). Very early iMac computers may need one (or more) firmware updates to use the US224. Which firmware update(s) is (are) needed depends on which Mac O/S version is installed in the early iMac. Apple provides details in its Apple Support Article #58174. PowerBook G3 Series (or later) with built in USB (or using a 3rd party PCMCIA USB Card) have been tested and work fine. Additionally, older PowerMac computers using 3rd party PCI-based USB cards also have been tested and work fine. Any iMac, G3 or G4 will work fine as well. A MacOS version earlier than 8.6 will not implement full USB support, and is not recommended. Again, plenty of RAM and fast drives are suggested.
cause damage to hearing, as well as to speakers, etc. Use only the enclosed USB cable to connect the US-224 and the computer. Do not use other types of cable for this purpose, as some cables contain resistors. If you attempt to use such a cable, the audio input and output will not work properly, and the sound level will be inaudible or very faint.
3.2.1 Windows
The US-224 drivers are available on the CD as executable installers. You�ll find two executable installer files on the disk, labeled as: �US224_Win98_Install_1_10.exe� (for Windows 98 Second Edition and Millennium Edition) and �US224_Win2k_Install_1_10.exe� (for Windows 2000 and Windows XP). Note that we have also included the individual driver files as a ZIP file, for users wishing to install via Windows Hardware Manager. However, we recommend using the installers, as they will also locate and uninstall any files pertaining to older versions of the US-224 drivers.
3.2 Installation
Because the US-224 is a USB device, connection is pretty straightforward. Simply plug the USB cable into the US-224, and the other end into your computer. Make certain that your computer�s USB host port is enabled. (Normally, most standard PC BIOS settings default to enabled, but make certain that it hasn�t been turned off in the BIOS). NOTE: Handle the enclosed CD-ROM with care. If it becomes dirty or scratched, it will be impossible for a computer to read it, and the software cannot be installed. If the disc becomes unreadable, a charge will be made for its replacement. Do not attempt to play the enclosed CDROM using an audio CD player, as this may
To install under Win98SE or ME: Note: The US-224 will run under Win98 SE (Second Edition) or ME (Millennium Edition). Due to its limited USB capabilities, First Edition Win98 is not recommended. Note: Run the Installer with US-224 turned OFF. Double click on the executable file �US224_Win98_Install_1_10.exe�. (The blue US-224 icon). The installer will run. Click the "Setup" button. The Welcome dialog box will appear. Click the "Next" button. The driver files will be installed to your hard drive.
