J-BC02 Manual of Use for Escalator Voice Announcer

一、Summary

J-BC02 escalator voice station is a high performance controller customized according to the special requirements of customers. The controller has two independent control and output, which can simultaneously and separately output different voice content to meet the needs of different heights of escalator broadcast. All the key components of the circuit adopt imported components to ensure reliable, stable and long time operation. Power amplifier uses 10 W high fidelity integrated circuit, through careful wiring and high reliable programming to make the product in the industry has a high cost-effective. The voice content in the 2-way SD card can be changed at will, and the voice format adopts the common MP3 format.

二、Main technical indicators

三、Connection method and terminal function

Note :1, all input is high level effective, voice trigger must be uplink or downlink effective before there will be a corresponding voice output.

The 2.485 interface carries on the data exchange and the control according to the two sides communication agreement content. Tips for Chinese Standard Operating

四、Voice content description

五、Overall dimension (unit: mm)

六、Debugging method

 A、 file format must be MP3 and WAV, broadcast files must be placed in the ZH folder of the card.

 B、Do not delete the 91 and 92 files in the B、ZH folder. The file must be named after the first two digits and can be annotated in Chinese, such as 21*. MP3'.

 C、 volume adjustment interface only need to connect two moving button can also adjust the volume button behind.

 D、 can play automatically without triggering in timing mode, the uplink and downlink input ports must have an effective to play the corresponding broadcast voice. The output speech can be changed flexibly by changing the input state of uplink and downlink.

 E、 the playback voice can be selected by changing the dial switch in the external trigger mode, the playback segment 2 is fixed to 01 segment, which can

六、Precautions for use

 1.SD card can not be hard pulled out, the card is self-propelled, press will automatically pop up. SD clamping force and other bad operations.

 2. make sure the wiring is correct and then electrified, otherwise the circuit will be permanently damaged.

 Do not enter liquid or corrosive gas 3. the product to avoid abnormal or damage.

 4. please use the original factory standard horn, otherwise the volume and power match will not be guaranteed.

 5. horn output end must not be short circuit to prevent burning out the internal circuit or function abnormal.
