a. On a desired extraction point of the extractor, connect the Tx port of the ber optic connector to the Rx port of a
ber optic connector on the receiving device (ber optic receiver or matrix).
b. On the same extraction point of the extractor, connect the Rx port of the ber optic connector to the Tx port of a
ber optic connector on the transmitting device (ber optic transmitter or matrix).
c. On the same extraction point of the extractor, connect an audio output device or device for DSP processing to the
3.5 mm, 5-pole captive screw connector.

d. For option bidirectional RS-232 and HDCP-compliance, connect the Tx port of the receiving device to the Rx port of the
transmitting device.
NOTE: Use the ports on the same connector that is connected to the extractor.
Step 3 — Power the Device.
Plug a standard IEC power cord into the connector to connect the FOX AEX 108 or FOX II 108 to a 120 V or
240 VAC, 50 or 60 Hz power source. All LEDs will blink together once for a multimode model or twice for a
singlemode model.
Operation and Features
After the ber audio extractor and all associated devices in the system are connected and powered on, the system is fully
operational.
Input Data Rate Switch
The recessed toggle switch on the font panel switches the ber audio extractor between 2G and 4G input data
rates. Move the toggle switch up for a 2G input data rate or down for a 4G input data rate. The default rate is 4G.
NOTE: 2G and 4G data rates apply to all inputs. These selectable rates are not for individual inputs.
After switching between 2G and 4G, cycle power to the FOX AEX 108 or FOX II AEX 108 in order to properly lock onto the
selected input data rate.
ATTENTION:
• Ensure all ber extenders within the system are compatible with the selected input data rate.
• Assurez-vous que tous les extendeurs bres dans le système soient compatibles avec le débit de données d’entrée
sélectionné.
Indicators
Tx Link and Rx Link LEDs — For each fiber connector, the Tx Link and Rx Link LEDs indicate the associated link is
transmitting or receiving light (not necessarily that there is data encoded in the optical light).
Audio Signal LEDs — The front panel Audio Signal LEDs light green when an audio signal
above -35 dBV is detected on the associated fiber input. The light turns off after the audio
signal level drops below the threshold for 10 continuous seconds.
Power LED — The front panel Power LED lights green when power is applied to the fiber
audio extractor.
