2.3 Electric Installation

Static IP Address Setting This subsection describes how to connect the 2N^® IP Base main unit to the power supply and LAN and how to connect other elements. Connection of RFID reader modules is contained in section 2.4 Extending Module Connection.

Electric Lock Connection

Connect the electric lock or another electric appliance directly to the device Active input or use a relay to switch the power supply. In the latter case, use an external lock supply. In any case, you are recommended to use low-consumption locks and keep the limits mentioned above.

Warning

When you connect a device containing a coil, such as a relay or an electromagnetic lock, it is necessary to protect the intercom against voltage peak while switching off the induction load. For this way of protection we recommend a diode 1 A / 1000 V (e.g., 1N4007, 1N5407, 1N5408) connected antiparallel to the device.

Main Unit

Power Supply Connection

2N^® IP Base can be powered either from an external 12 V / 2 A DC source or directly from the LAN equipped with PoE 802.3af supporting network elements.

External Power Supply

To make your device work reliably, use a safe 12 V ±15 % voltage supply, Part No. 91341481E (SELV), dimensioned for current consumption according to the required performance, for the main unit supply (2 A, 24 W).

PoE Power Supply

2N^® IP Base is compatible with the PoE 802.3af (Class 0–12,95 W) technology and can be fed directly from the LAN via the compatible network elements. If your LAN does not support this technology, insert a PoE injector, Part No. 91378100, between 2N^® IP Base and the nearest network element. This power supply provides 2N^® IP Base with 12 W for feeding of the main unit.

Combined Power Supply

2N^® IP Base can be fed from an external power supply and PoE at the same time.

LAN Connection

2N^® IP Base is connected to the Local Area Network (LAN) via the UTP/STP cable (Cat 5e or higher) terminated with an RJ-45 (LAN) connector. As the device is equipped with the Auto-MDIX function, both the straight and crossed cable can be used.

Reset Button

Located among the main unit connectors, the Reset button helps you reset the factory default values, restart the device, find the device IP address and switch the static/dynamic mode.

IP Address Finding

Follow the instructions below to identify the current IP address:

• Press and hold the RESET button.
• Wait until the red and green LEDs go on simultaneously on the device and the acoustic signal  can be heard (approx. 15–35 s).
• Release the RESET button.
• The device automatically announces the current IP address.

Static IP Address Setting

Follow the instructions below to switch on the Static IP address mode (DHCP OFF):

• Press and hold the RESET button.
• Wait until the red and green LEDs go on simultaneously on the device and the acoustic signal  can be heard (approx. 15–35 s).
• Wait until the red LED goes off and the acoustic signal  can be heard (approx. for another 3 s).
• Release the RESET button.

The following network parameters will be set after restart:

• IP address: 192.168.1.100
• Network mask: 255.255.255.0
• Default gateway: 192.168.1.1

Dynamic IP Address Setting

Follow the instructions below to switch on the Dynamic IP address mode (DCHP ON):

• Press and hold the RESET button.
• Wait until the red and green LEDs go on simultaneously on the device and the acoustic signal  can be heard (approx. 15–35 s).
• Wait until the red LED goes off and the acoustic signal  can be heard (approx. for another 3 s).
• Wait until the green LED goes off and the red LED goes on again and the acoustic signal  can be heard (approx. for another 3 s).
• Release the RESET button.

Factory Reset

Follow the instructions below to reset the factory default values:

• Press and hold the RESET button.
• Wait until the red and green LEDs go on simultaneously and the acoustic signal  can be heard (approx. 15–35 s).
• Wait until the red LED goes off and the acoustic signal  can be heard (approx. for another 3 s).
• Wait until the green LED goes off and the red LED goes on again and the acoustic signal  can be heard (approx. for another 3 s).
• Wait until the red LED goes off and the acoustic signal  can be heard (approx. for another 3 s). 
• Release the RESET button.

Device Restart

Press the RESET button shortly (< 1 s) to restart the system without changing configuration.
