There could be several reasons, why 2N IP audio device: 2N® NetSpeaker / 2N® NetSpeaker Lite / 2N® NetMic / 2N® NetStreamer is not connected to the 2N NetSpeaker Server :
In factory default IP audio device obtain IP address automatically (DHCP client is ON).
CAUTION even if other devices in the network obtain IP address automatically, 2N IP audio unit does not have to due to the restrictions set by the IT department in the network. This setting automatically assigns IP addresses only to known/registered devices in the network based on their MAC addresses!
- In case device did not obtain IP address automatically, go to menu Administrator > Netspeaker scanner . Displayed IP address in field DHCP would be: 0.0.0.0 (see picture below).
For more details contact your IT department. In this case it could be MAC address restriction in the network. Provide MAC address of the device to your IT department and they will register it and allow automatic assignment of the IP addresses.
Second option is to turn the DHCP client OFF and setup IP address manually. In this case it is necessary to know some free IP address which can be used for NsP unit in the network. It means that this IP address (the one you would like to use) is not assigned to any other IP device in the network (you can use ping command to check it). Do not forget to set up the IP mask = subnet of the network.
Manual settings could look like this: IP address: 192.168.1.151 IP mask: 255.255.255.0
Firewall can also block connection of the unit to the NetSpeaker Server
Do you have firewall switched ON? It can cause that if 2N® NetSpeaker unit disconnects from the server and then tries to connect again via the same port, firewall (eg, ESET Smart Security) will not let it go through. This is not the common issue but it could be one of the reason why you cannot see NsP units in menu Destinations & Zones.
Picture below shows the situation when the network automatically assigns IP addresses (there is DHCP server in the network) but the device (e.g. NsP unit is not recognized = IT department does not know its MAC address). In this case IP address for NsP unit would not be automatically assigned .
Picture below shows an example of manually assigned IP address and IP mask,when the DHCP client has been switched OFF:
3. Password for authorization is used: IP audio device authentication to the Server / Server authentication to the IP audio device.
IP audio device is not connected to the NetSpeaker Server even all parameters as: IP address, domain, connection mode are set-up correctly? Most probably you have previously used password for device/server authorization.
