INSTALLATION
①Amplifier output interface: Internal power amplifier output port, it offer two way
power amplifier output, it can output from amplifier when the terminal is receiving
broadcasting or playing the background music. When the terminal power is 20W,
amplifier output 2*10W; when the power is 60W, amplifier output 2*30W.
②Alarm input/output interface:
G-A: alarm input interface, it can trigger the NandFlash card built-in ShortIN folder
audio playing when it`s closed. when the two pins are short circuited, the audio
terminal will automatically make some special operation (eg: generate an alarm
signal and sent to the server or send the alarm from local terminal etc) . Alarm
button, short circuit signal generator all these devices all can access to this port;
O-1: alarm output interface, alarm output is triggered by server software, it also
triggered by alarm input or shutoff signal to play the alarm function (eg: open the
electronic lock door). Alarm output port the maximum loaded current is 1A, the
highest
voltage is AC100V(or DC24V).
③The volume adjustment knob: used for line input volume adjustment, clockwise
for up, anticlockwise for down.
④Forced upgrade or play device IP button When the terminal without power on,
press button by tweezers or pin, then power on till 5 seconds, so that it will enter
into upgrade status ( press this button can voice play the terminal IP and subnet
mask information in free status).
⑤Line input interface: it can connect the external analog sound source (eg:
dynamic microphone, computer...etc) to this port.
⑥Line output interface: this port output the restored audio signal; It can used as a
sound source access to the active speakers, audio pre-amplifier, sound console,
audio amplifier device...etc.
⑦Network interface: this port connect with Ethernet by cables.
⑧STATE: status light
If the terminal is upgrading firmware, the status light is flashing in red and green; If
the terminal is not login or required to login, the status light is flashing in red. If the
terminal logined server and in free status, the status light is normal green on; If
the terminal logined server and is executing the task, the status light is flashing in
green.
⑨The power interface: connect 24V power DC power supply.
⑩ANT: antenna interface
