Replacing an older Model IP7
If the IP7-FX is being used to replace an existing an existing IP7ST/STX, IP7-SS8/SE8 or an IP7-FD, please note the following:
• The J3-7 (Case) connector on older models was an extra
ground. If replacing an older model with an IP7-FX, any
wire connected to J3-7 should be moved to J3-6.
• If replacing an IP7-ST/STx, make sure the internal ST-MIC
switch (located on the DIN clip side) is set in the same
position on the IP7-FX
• If the older IP7’s J2-6 (SPKR 8Ω+) and J2-7 (SPKR 8Ω-) is
connected to an amplifier or amplified speaker, use the IP7FX’s J2-3 (Line Out) and J2-4 (GND) instead
• If replacing an IP7-SE8 / IP7-MSR-BRD with an IP7-FX, the
IP7-MSR-BRD can be eliminated by changing the IP7-FX’s
ST-MIC internal switch to the ST position
• The IP7-FX does not support the Aiphone IE/ IF series call
station. An IP7-ST/STx must be used
• Other than the exceptions noted above, the J1, J2, J3, and
network can be moved over to the IP7-FX
Connecting to an Ethernet Network
The Ethernet 10/100 connects to a 10/100 network switch port. Port 2
10/100 allows an additional IP device to be connected to the network
without the need for an additional network drop. The second port is not PoE
capable.
• Plug a Cat5 cable into the RJ-45 connector labeled Ethernet 10/100
and connect the other end to a 10/100 switch.
• To optionally connect a second IP device to the network, plug a Cat5
cable in the RJ-45 connector labeled Port 2 10/100
• The Ethernet 10/100 connector supports auto “MDIX” and can be
plugged directly into a PC for diagnostic purposes.
Connecting Power
The IP7-FX auto senses the power source and voltage. An external power
source will always override PoE power.
PoE
Plug a Cat5 cable from an 802.3af compatible switch or injector into the RJ45 connector labeled Ethernet 10/100. 15.4 watts will be requested from
PoE (802.3af compatible) Power Source Equipment (PSE).
Page 12

External Power
• The 2.1mm Power Jack (center tip positive) and the J1-1(+) / J1-2(-)
connectors both accept 12VDC at 1.2 amps or 24VDC at 2.5 amps
(With 12VDC, the IP7-FX can supply up to 8 watts to the speaker.
With 24VDC, the IP7-FX can supply up to 25 watts to the speaker)
• DO NOT supply power to both the 2.1mm Power Jack and the J1-1
and J1-2 connectors
USB Power
The USB connector can be used to power up the unit for diagnostics or lowlevel firmware flashing. Plug a USB cable from a PC into the USB-B
connector. The unit will power up but will not be able to be used for audio
operations.
Audio - Mic and Speaker
Understanding Full Duplex Audio
The IP7-FX Full Duplex Operation is often referred to as Speakerphone or
Hands-Free mode. The technology to enable 2-way conversation without
acoustic feedback involves a process called Acoustics Echo Cancellation
(AEC). For AEC to be effective, the total system design needs to be
considered. This includes incorporating sophisticated DSP electronics and
optimizing the Speaker Frequencies and placement of the speaker and
microphone based on the maximum volume to be played on the speaker.
The Digital Acoustics IP7-FX series has highly advanced DSP electronics with
software that can optimize the endpoint based on the physical environment.
In full duplex echo cancellation mode, when the distance between the
microphone and speaker is small (under 24”), the speaker volume and
microphone sensitivity are limited to help prevent feedback. As the distance
between the two increases, the microphone sensitivity and speaker volume
can increase as there is less chance of feedback.
Understanding Half Duplex Audio
In half duplex audio mode, only the speaker or microphone is active at any
one time. In this mode, the speaker volume and microphone sensitivity can
both be maximized since there will not be any feedback.
Understanding Paging Audio
In paging mode, only the speaker will be active. The speaker volume can be
maximized since there will not be any feedback.
Simple ‘dialog’ choices in the configuration software offer several Audio
Profiles for different environments. Please refer to the Admin Console
Reference Guide for more information on selecting Audio Profiles.
Page 13
Page 9
Microphones
The IP7-FX can receive audio through a microphone and transmit it across
the network to be played or stored. There are several types of microphones
with different pickup patterns (omni directional, unidirectional, etc.). The
IP7-FX supports Electret and Line Level Mics as well as TalkBack Speakers.
Electret Microphone
An electret microphone (sometimes referred to as un-pre-amplified mic)
transmits “mic level” audio to the IP7-FX. To use an electret microphone:
• For best results and to minimize interference connect to the
microphone to the IP7-FX with 18-20 AWG shielded wire
• The Microphone wire must NOT be in the same jacket as the Speaker
wire!
• Connect the plus and minus leads to the IP7-FX’s J2-1 (Mic+) and J2-2
(Mic-) terminals
• Connect the shield to the IP7-FX J2-4 (GND), but do not connect the
shield on the microphone end
Some examples of electret microphones are the ETS ML1-x series and the
Louroe x-ML series.
Line Level Microphone
A line level mic (sometimes referred to as a powered or pre-amplified
mic) transmits “line level” audio to the IP8-FX. To use a line level mic:
• Connect the Black (or Audio) lead to the J3-4 (Line In) connector
• Connect the Shield (or Ground) to the J3-6 (GND) connector
• Connect the Red (or Power) lead to the J3-7 (MIC PWR) connector
Some examples of line level microphones are the ETS SM1 series and the
Louroe Verifact series.
TalkBack Speaker
Some 8 Ohm speakers work well as a microphone. To use a speaker as a
microphone:
• Connect the two speaker leads to the J2-1 (Mic+) and J2-2 (Mic-)
connectors. The connections are polarity independent
• Set the recessed ST MIC switch (connector 9 – next to the DIN clip) to
the ST position using a small screwdriver
Some call stations only have a single speaker that is used as both a speaker
and a microphone (also known as single transducer mode). The IP7-FX can
also support this configuration in half duplex operation.
Page 14
Page 10
• Connect the two speaker leads to the J2-6 (SPKR 8Ω+) and J2-72
(SPKR 8Ω-) connectors. The connections are polarity independent
• Set the recessed ST MIC switch (connector 9 – next to the DIN clip) to
the ST position using a small screwdriver. The ST MIC switch must be
in the MIC position for all other configurations!
• Make sure the IP7-FX software configuration is NOT configured for Full
Duplex
An example of a TalkBack Speaker is the Visiton FRS8-8.
Speakers
The IP7-FX receives audio from the network and plays it on its speaker. It
can drive one or more speakers, a self-amplified speaker or an analog
amplifier connected to one or more speakers. For best results and to
improve performance, connect the speaker or amplifier to the IP7-FX using
18 AWG wire.
Single 8 Ohm Speaker
To drive a single 8-Ohm speaker, connect the speaker leads to J2-6 (SPKR
8Ω+) and J2-7 (SPKR 8Ω-). The connections are polarity independent.
Amplified Speaker or Analog Amplifier
To drive an amplified speaker or analog amplifier connect the amplifier’s
Audio+ signal to J2-3 (Line Out) and the Ground to J2-4 (GND).
Do not connect the IP7-FX J2-6 and J2-7 connectors to an
unbalanced audio signal. This will cause permanent damage
and void the warranty!
Multiple Speakers
Multiple speakers are typically used if the IP7-FX will be used for
overhead paging. If more than one speaker is connected to an IP7-FX,
all speakers will sound when audio is sent to it.
When driving multiple speakers, it is recommended that a 25/70V
distribution line be used. This requires the optional 25/70V
transformer (part# COMTR25/70-324J) for the IP7 and speakers with
25/70V transformers.
Multiple Speakers using 25/70V transformers
Due to transformer loss, the IP7-FX will only:
• Supply about five watts to the speaker output when using PoE or
12VDC.
• Supply about 30 watts to the speaker output when using 24VDC
Page 15
Page 11
Please note the following guidelines:
• Each speaker must have its own 25/70V transformer
• Do not mix Speakers tapped for 25V with a 70V distribution line
or speakers tapped for 70V with a 25V distribution line
• All speakers must be wired in parallel.
• Speakers should be installed within 500 feet (150 meters) of the
IP7-FX using 18-gauge wire. For longer runs, increase the wire
gauge
• Each speaker may be tapped differently
• The total wattage of the selected speaker taps cannot exceed the
five watts (12VDC or PoE) or thirty watts (24VDC) available from
the IP7
• Maintain the same wiring polarity between speakers
To use the optional transformer:
• Mount the transformer next to the IP Amplifier
• Connect the J2-6 (SPKR 8Ω+) and J2-7 (SPKR 8Ω-) (polarity
independent) from the IP Amplifier to the 8 Ohm side of the
transformer
• Connect the 10 watt tap and common from the other side of the
transformer to the wires leading to the speaker(s)
• Refer to the instructions included with the transformer for
additional information
Page 16
Page 12
Multiple 8 Ohm Speakers
The IP7-FX is also capable of driving multiple 8 Ohm speakers without
25/70V transformers.
• Two 8 Ohm speakers must be wired in series
• Four 8 Ohm speakers must be wired in series-parallel
Please note the following guidelines:
• Connect the Speakers to the J2-6 (SPKR 8Ω+) and J2-7 (SPKR
8Ω-) (polarity independent)
• Speakers should be installed within 200 feet (60 meters) of the
IP7-FX using 18-gauge wire
• The total watts available from the IP7-FX are distributed equally
among the speakers so they will all have the same volume
Page 17
Page 13
Line Out
The Line Out generates a standard 2Vpp signal (two Volts peak to peak) to
drive a Line In signal.
To connect Line Out to a standard Line In signal, amplifier or amplified
speaker:
• Use 18-20 AWG shielded wire
• Connect J2-3 (Line Out) to the amplifier’s “+” connector
• Connect J2-4 (GND) and the amplifier’s “-“ connector
• Follow amplifier manufacture’s recommendations for balanced vs
unbalanced audio signals.
• If any noise is heard in the output signal, connect the J2-4 (GND) to
the negative terminal on the amplifier’s power source
Line In
The Line In is an alternate audio input and must be selected as the Input
Source instead of the Microphone in the IP7-FX software configuration.
Some devices that require a Line In are Line Level Microphones, Microphone
mixers, mobile phones or analog amplifiers.
To connect Line In:
• Use 18-20 AWG shielded wire
• Connect J3-4 (Line In) to the device’s “+” connector
• Connect J3-6 (GND) to the device’s “-“ connector
• Connect J3-6 (GND) to the shield and leave it floated at the line in
device
• Connect the shield to the device’s ground connector
Talk (Call) Button
The optional Talk Button connector is used to initiate a call to the
TalkMaster software or to a SIP Server.
To wire the Talk Button, connect J2-5 (Talk) to the Button, and then
connect J2-4 (GND) to the Button’s other contact. Optionally, the Button’s
other contact can be attached directly to one of the Speaker terminals. Use
18 AWG wire.
Dry Contact Relay
The Relay connector provides a dry contact output from the IP7-FX suitable
for activating equipment such as electronic door strikes, strobe lights or
CCTV cameras. Normally Open (N/O) or Normally Closed (N/C) can be
chosen. Use 18 AWG wire.
Page 18
Page 14
The Relay is rated at 250 VAC / 30VDC @ 60W / 1500 VAC Isolation.
• Connect either J3-1 (NO) for a normally open relay or J3-3 (NC) for a
normally closed relay to the device to be controlled
• Connect J3-2 (Common) to the other side
• Ensure Relay has been properly configured in the Intercom’s Software
Configuration program
SNSR/3.3V
The IP7-FX supports an input sensor that can be used for a variety of
applications. The sensor can be defined as Active when closed to ground
or Active when open to ground via software. Digital Acoustics’
TalkMaster™ Software provides functionality for monitoring the status (open
or closed) of a door via the sensor.
• Connect J3-5 (SNSR/3.3V) and J3-6 (GND) to a door sensor or device
that can provide a contact closure
• Ensure Sensor has been configured to be Activate when closed to
ground or Activate when open to ground in the IP7-FX’s software
configuration
Optionally, this connector can be used to power an LED at 3.3V (current
limited).
• Connect J3-5 (SNSR/3.3V) to the positive side of the LED and J3-6
(GND) to the negative side
• Ensure Sensor has been configured to Activate when open to
ground in the IP7-FX’s software configuration to prevent the sensor
alert from being generated
