How to Achieve Ideal Acoustic Properties
To ensure the minimum acoustic pressure according to the EN 81-28:2015 standard
requirements, the holes in the communicator speaker covering panel should occupy 20 % of the
speaker area at least and be placed in front of the speaker.
Make sure that the speaker and the microphone fit tightly to the covering panel. If this is
impossible due to an uneven panel surface, we recommend that a speaker seal is used to avoid
sound leaking into the space behind the panel. A good microphone sealing is crucial for high-
quality sound transmission and good intelligibility.
Try to minimize the microphone - speaker acoustic feedback while mounting.
Indicator Mounting
There three types of 2N
®
LiftIP 2.0 state indicators:
Illuminated pictograms are part of the cabin control panel.
LEDs located directly on the
2N
®
LiftIP 2.0 electronics.
Two LEDs (yellow, green) connected to the 2N
®
LiftIP 2.0 electronics in the cable version.
2.4 Connection

LiftIP 2.0 Connection
2N
®
LiftIP 2.0 is connected to the LAN via a Cat-5e or higher UTP cable terminated with RJ-45
(LAN connector). 2N
®
LiftIP 2.0 can be fed via PoE or from an external power supply (10–30 V DC,
0.5 A). Once connected to the LAN, 2N
®
LiftIP 2.0 gets the IP address from the DHCP server.
Or, retrieve the IP address using 2N
®
Network Scanner , which includes the network scanner.
Refer to 2N
®
LiftIP 2.0 LAN Location via 2N® Network Scanner for more details.
By default, 2N
®
LiftIP 2.0 receives DTMF via RFC-2833 or in-band / SIP INFO detection.
