3 About voice intercom demo
1) plug the speaker to the white outlet;
2) fix the antenna to the demo board;
3) Connect the DC power supply (or Battery) to the demo board,please pay attention to the power polarity;The DC power voltage could be 3.3V-5V,  the recommend DC power is 4.0V; 

      The current capacity should be double of the transmit current.

4) After connect the power supply correctly, the  power Led would turn on;
5) When press the PTT key,The red  LED  for transfer state indication  would turn on;  Now you may talk;
       Release the PTT Key , Red LED would turn off,it into the receive state,you may receive the talking from opposite side ;

 

4 How to set the parameter of the module
   The setting command please refer 《serial communication protocol》,You may ask it from our company;

   Special comment:
      

1) The serial port connection Schematic diagram.
       (just a sample for FRS_1WU module)


2.png   
     Please connect the  demo board TXD,RXD , GND with the  USB TO UART board
     Comment:
          We leave two UART interface for user, 
         One is RS232 level, please add the MAX232 yourself;
         One is TTL level (3.0V),  the sample is for TTL level.
  3.png

2)  PC COM port setting
     Serial port;May be COM1,COM2.COM3…. etc. 
     Baut: 9600 only;
     Parity:None 
     Data:8
     stop:1

3) Frs module parameter setting:
    ( The command below is for analog module, not for DMR module)
    Here is a example for GROUP COMMAND Setting:
    AT+DMOSETGROUP=0,450.0500,450.0500,0,2,0,0 
    (An “Enter” must be added at the end of the command)
    The parameter contents are as below in turn:
       0:Narrow
       450.0500:Transmit frequency( MHZ)
       450.0500:Receive frequency ( MHZ)
       0:Receive CTCSS
       2:Squelch level
       0:Transmit CTCSS
       0:Rf output power and etc. :
  Comment:
   1) The Tx Frequency and Rx Frequency can be set alone.
   2) The Tx CTCSS and Rx CTCSS  can be set alone.
   3) The parameter can’t be kept because of this demo board without MCU.

4-1.png


      At the end of the command, a “enter” must be done then click the “send”; 
 If the command is sent correctly, then the module returns  
+DMOSETGROUP:0    to the receive area

 The other parameter setting is same as the Group setting, Please refer 《UART communication protocol》


4)  Short message / Data transfer 
     Prepare 2 sets PC, All the PC must connect the demo board correctly;
     Suppose PC1 as the data transfer,and PC2 as the data receiver;

     Transfer data by PC1:
  1) Input the command with Text format ( Don’t check the “Send as hex”)
     AT+DMOMES=7ABCDEFG
   (must click “Enter” key once from the keyboard)

5-1.png    

   Because the SMS length should be Hex,  The command should be converted into HEX format, And modify the Length manually.
   

  2) Check the item of serial tool“Send as HEX”
    Now the command of text format is converted to HEX format automatically;
    41 54 2B 44 4D 4F 4D 45 53 3D 37 41 42 43 44 45 46 47 0D 0A
    The “37” Should be modified to be “07” manually , because the Length Byte is Hex;
    The right command should be:
    41 54 2B 44 4D 4F 4D 45 53 3D 07 41 42 43 44 45 46 47 0D 0A

6-1.png

 3) Click “Send”
 4) Once the message is sent correctly by module,The module would report the transfer results to PC, that is , the contents as below would be displayed on PC1.
     + DMOMES:0

      Receive data by  PC2:
          Once received a message /data , The receive area would display as below:

1) When not check“Receive as HEX” ,The display contents would be: +DMOMES=*ABCDEFG

7-1.png


2) When check “Receive as HEX” ,The display contents would be:
    2B 44 4D 4F 4D 45 53 3D 07 41 42 43 44 45 46 47 0D 0A

5.  Comment
1) The default frequency of the demo board 
       (Not for DMR module)
       UHF : 450.050MHZ (for both Tx and Rx)
       VHF: 150.050MHZ   (for both Tx and Rx)
       The default CTCSS is 0;
2) For the all parameter you set, it couldn’t be kept once power off;

3)   About the antenna we sent to you
      For 1W UHF module, The antenna central frequency is 450M + - 5M;
      For 1W VHF module, The antenna central frequency is 150M + - 5M;

      The antenna central frequency must be same with the module working frequency, otherwise, it would seriously affect the transmit power and the receive sensitivity;  

We leave two UART interface for user:

  • One is RS232 level, please add the MAX232 yourself;
  • One is TTL level (3.0V), the sample is for TTL level.

Send uart command via the UART tools to set the parameter of the module.

Comment:

  • The Tx Frequency and Rx Frequency can be set alone.

  • The Tx CTCSS and Rx CTCSS can be set alone.

  • The parameter can’t be kept because of this demo board without MCU.

===============================================================================================

NOTES:

  • 1) For more detail specification,please contact us. thanks!
  • 2) the demo board is subject to be upgraded without notice!
