6.3 8000 Computer Connection (USB/Serial)

You can connect the FONIX 8000 Hearing Aid Test System to your computer using

either the serial port on the back of your analyzer or one of the USB ports. By default,

the FONIX 8000 uses the USB port for the connection. You will need to conﬁgure the

BIOS setting of the system in order to use the serial port instead.

Be extremely careful when change the BIOS Conﬁguration!!! If a bad conﬁguration

is made, the 8000 Analyzer may become unusable.

To Enter the BIOS Conﬁguration Screen

1. Plug a USB keyboard into the back of your 8000 analyzer.

2. Use CTRL+ALT+DELETE to reboot your analyzer or just turn it off and turn it

back on again.

3. Hold down the delete key when the BIOS splash screen appears. This appears

before the linux startup information. If you see the linux startup information,

you missed the BIOS splash screen and will need to repeat Step 2.

Important: The BIOS Splash screen should be titled “Phoenix AwardBIOS CMOS

Setup Utility.” If the title is something else, do NOT continue with these instructions.

Instead, contact the Frye factory (support@frye.com) for alternate instructions. The

following instructions are ONLY for the BIOS titled “Phoenix AwardBIOS CMOS

Setup Utility.”

To Conﬁgure the Computer Connection for Serial Port:

1. Follow the steps in the “To Enter the BIOS Configuration Screen” Section.

2. Use the up-down arrow keys on your USB keyboard to go to Integrated

Peripherals and press <Enter>.
