The IP Address information and all Intercom options can be reset to factory
defaults by the following procedure:
• Unplug the Power
• Press and hold the “Vol +” and “Vol -“ buttons

Connecting 1/8” (3.5mm) Audio Plug to the Pluggable connectors
To connect a Mic, Line In or Line Out to the pluggable connectors via a 1/8”
audio plug, the audio plug should be wired as follows:
• The Tip should be wired to positive
• The Sleeve should be wired to minus or ground
• On stereo plugs, the Ring should be left unconnected
Reducing electrical noise in audio
Improper wiring can cause noisy audio when transmitting microphone audio
from the IP7-FX. To minimize the possibility of this:
• Locate the unit at least one meter away from transformers, stepper
motors or other noise producing equipment
• Use shielded twisted multi-conductor cable for microphone audio and
follow the grounding recommendations
• Do not run audio cable in the same conduit with AC power
• Attached J3-6 to an earth ground
Viewing tech support info via the USB port
If requested by Digital Acoustics Support, a USB cable can be attached to the
IP7-FX to capture additional information.
• Attach a USB cable to the USB-B connector on the unit.
• Attach the other end of the cable to a PC running Windows®.
• Open the Windows Device Manager to determine the virtual Serial port
that has been assigned
