IV. Setting Operation of the Terminal
4.1 IP Address Setting
The speaker can be customized to modify the network parameters. If you want to modify the IP address, please
read this section carefully for alteration methods:
Method 1:
1. The IP address alteration of the host / computer requires the IP address of the host / computer and that of
the terminal on the same network segment. The IP address of the terminal is attached to its body when it
leaves the factory, so please pay attention to the IP address on its body. For example, the terminal IP
address is 192.168.66.187, while the IP address of the host / computer should be 192.168.66.XX (Note: the
set IP can not appear IP conflict phenomenon);
2. Enter the IP address of the terminal on the IE browser after connecting the host / computer and the terminal,
and then enter the interface as shown in Pic. 1 (The default username:admin, password: 123456), and then
click “OK” button to enter the interface as shown in Pic. 2;
3. Click “Save” button to to display the word “Terminal parameter setting success” at the top of the interface
after altering the terminal IP address or server address under “Network setting”.

interface on the main interface of the network public address system host (the “Settings” button is in the
lower right corner of the main interface) and click the “Device Management” button to enter the following
interface as shown below.
(Pic. 5)
The host system will automatically search the terminal equipment of the PoE255 network speaker, or you can
