I NTEG ATED SWITCHES
Tal Push to Talk. Turns on local microphone.
Monitor/Open
• In 'Client' mode, Monitor sets 'Talk' ON, as if the Talk
button is being held down for hands free speaking.
• In 'Server' mode quickly pressing Monitor turns on listen
mode on by turning the Client Intercom’s microphone on.
Press Tal to talk to the Client Intercom. Quickly
pressing Monitor a second time turns off remote
listening
• In ‘Server’ mode (Direct Mode), pressing and holding
this button activates the GPIO4 or the relay (dry contact)
on the “Client Intercom”
Volume Up
Volume Down
Sets volume locally (also set via TalkMaster). There
are 7 (seven) volume level settings.

may be unplugged, or the cable may
be defective.
FLASH OFF - -
Intercom has not been configured yet
or has been configured for DHCP, but
no DHCP Server is available. To turn
off DHCP, power cycle the Intercom
while holding down the + and - buttons
(Volume up and Volume down)

E XTE NAL MIC OPHONE SELECTION
ii3 supports high quality voiceband audio. Integrated AGC amplifiers
support a wide range of microphone inputs and low cost electret
microphones ($3usd) will have similar intelligibility as expensive
"professional" microphones ($10-$50usd). Microphones mounted
externally should be in a vibration and moisture free environment.
E XTE NAL SPEAKE CONNECTIONS
A 3.5mm Audio ut jack is provided for headphones, external
speaker or an amplifier. When connecting speakers to the Audio
Out jack, user an external amplifier or powered speakers
N ETWO K WI ING USING CAT5
Ii3 series products connect to network hubs and switches using
standard Straight Through wiring, similar to PC connections and
do not support mdi auto-detection. No special connections or
cabling changes are needed under normal operating
environments.
Crossover Cable Connections
Use a Crossover cable ONLY when using 2 ii3 intercoms in DI ECT
CONNECTION (Server/Client) or when using a PC to single ii3
intercom WITHOUT a hub/switch interconnect.

I NTEG ATED 2- PO T SWITCH OPTION
An integrated 2-port switch is an option available on all models of
the ED and ES series. The 2-port switch allows connection of an
additional IP device from a single network drop.
Important - ii3 intercoms with the integrated 2 port switch are
supplied with a regulated 5vdc (750mA) power supply. Other
intercoms in the ii3 series use 7.5vdc or 9vdc power supplies.
Using the wrong power supply could damage the unit.
Connecting ii3 Intercoms
With integrated 2 port switch
• Connect a regulated 5vdc power
supply with 2.1mm plug, center
tip positive, min 750mA
• Connect an Ethernet cable from
a hub/switch into the RJ45
connector closest to the edge of
the intercom.
• Connect an Ethernet cable to
any other IP device using the
RJ45 connector that is next to
the power jack.

If the upstream device is another hub/switch that does not have mdix
capabilities, use a crossover cable

P O E O PTION
A PoE (Power over Ethernet - 802.3af compatible) option is available on all
models in the ED and ES lines.
• Each ED or ES intercom will draw 7 Watts from your network switch
or injector
• On models with the PoE and integrated 2-port switch options, PoE
does not pass through to other devices connected to the 2
nd
port
• Do not plug power into the external power jack and connect the
Intercom to a PoE power source at the same time
T OUBLESHOOTING
 Verify power connections. The "Active" or LD10 LED on should be on or
flashing.
 Verify that the “Link” or LED is on solid. If not, a valid network
connection is not present.
 ii3 Intercoms may operate across some firewalls or VPN's. They will
need to be configured locally (for setup) and will need to be assigned to
the STATIC IP addresses of the TalkMaster PC.
 If the intercoms have been configured for DHCP and no DHCP server is
available, re-power the intercom while holding down the Volume Up and
Volume Down buttons. Wait 15 seconds, then Search for the Intercoms
again and assign a static IP address.
 If you cannot detect any intercoms using the TalkMaster Intercom
Configuration Utility screen try directly connecting the PC (running
TalkMaster) to the ii3 intercom using a crossover cable (disconnected
from the network).
 To reset the Intercom’s configuration back to factory defaults, re-power
the intercom while holding down the TALK and Volume Up buttons.
This will erase the Intercom’s IP Address settings, Intercom Name and
all options. Wait 15 seconds, then Search for the Intercoms again and
re-configure the Intercom.

F I MWA E OS UPG ADES
All ii3™ intercoms use internal Flash memory. Operating system
(OS) and firmware may be upgraded to include new revisions or
custom options. TalkMaster™ software is required to enable and
program the Flash memory upgrade feature.
