Alarm input triggers SD card to broadcast audio
When the alarm input 1 is short circuit connected, the IP amplifier plays the "1.mp3" audio file in the "short circuit input.001"
file in the MUSIC folder, and stop playing when disconnected.
Similarly, the alarm input 2 is short circuit connected to play the "2.mp3" audio file in "short circuited input.002", and the
alarm input 3 is short circuit connected to play the "3.mp3" audio file in "short circuited input.003".
The audio files placed in "short circuiting input.001" must be named "1.mp3", the audio files placed in "short circuiting
input.002" must be named "2.mp3", and so on.
The mentioned three audio files must be MP3 files in 128K format and the name can not be changed, only the content of the
audio files can be replaced.
The folders of "short circuit input.001" and "short circuit input.002" can be initialized and created by remote SD card tools,
while the folder of "short circuit input.003" needs to be created manually.
Fault exclude
Why the terminal is still "offline"?
1).Check the software server and the main controller is normal opened or not. It`s required to close all firewall before open
the software server (including system built-in firewall and other antivirus software firewall).
2).Check the network connection is normal or not. After the terminal powered on, the network port green light is norm on,
meantime the orange light will be short and fast flash, it means the network cable hard-connected normal. If the network port
green light is not on, it means the network hard-connected problem, please check the terminal network cable and switcher
whether they work normal, damaged and disconnect or not etc.
3).Check the terminal IP setting. Please check the terminal ID, sever IP, local IP, gateway IP ...etc parameters.
Why it appears "terminal network services (UDP) start fail" warning within the process of start server software?
Appearing this warning information, it’s usually the local network connection has been disconnected, please connect the
local network cable well and exit the software, then restart it.
