XZ-DT25-HXX Frequency
Default frequency channel is CH0,frequency of the 0 channel can be arbitrarily set and saved by the software. Users can input/rewrite any frequency they need in the software.
Remark: our XZ-DT25-H(25w),XZ-DT25-M(5W),XZ-DT25-L(2W/500mW) and XZ-DT25-U(100mW) can communicate with each other,users can choose suitable radio modems according to actual use.
Software Function Setting
1.1 Enter setup mode
The hardware enters the setup mode: connecting the 8th foot with Ground and the green light of radio is always bright, the radio enters the setup mode, the serial port rate is 9600 8N1.
The software enters the setup mode: at the current baud rate, 3 + numbers are sent continuously, XZ-DT25H enters the setup mode, and the serial port output is OK
Format + + +
Return OK
1.2 Channel 0 Frequency Setting(this frequency is the working frequency of 0 channel
Format >WF0/RX:453.25000/TX: 453.25000
Return <Channel_0: RX:453.25000/TX:453.25000
Explain >WF0 means working frequency when writing channel 0
RX: means receiving frequency453.25000 MHz ,please notice frequency needs to be accurate to 5 digits after the decimal point；
TX: means transmitting frequency 453.25000 MHz , please notice frequency needs to be accurate to 5 digits after the decimal point；
The same XZ-DT25H receiving and transmitting frequency settings can be the same or different, but modules in the same communication system must have the same receiving and transmitting frequency then they can communicate. Dip Switch can only set frequency in Channel 0.
1.3 Interface Baud Rate Setting
Format >WBA
Return <Com_Rate:1200
Explain >WB means interface baud rate
A~G means 1200~115200bps；A=1200，B=2400，C=4800，D=9600，E=19200，F=38400,G=115200
1.4 Parity Bits Setting
Format >WVN
Return <Verify:8N1
Explain >WV means Interface Parity Bit
N、E、O means 8N1、8E1、8O1
1.5 Air Baud Rate Setting
Format >WAA
Return <Air_Rate:1200
Explain >WA means Air baud rate
A~G means 1200~115200bps；A=1200，B=2400，C=4800，D=9600，E=19200，F=38400,G=115200
Notice: if air baud rate and interface baud rate are set the same, can transmit data continuously. To transmit longer distance, air baud rate can be set lower, while interface baud rate can be set higher.
1.6 Read all Parameters Command
Format >R
Return <Channel_0: RX:453.25000/TX:453.25000
<Com_Rate:1200
<Air_Rate:1200
<Verify:8N1
Explain Output XZ-DT25H current working parameters
1.7 Exit Setup Mode
Format >E
Return OK
XZ-DT25H exit setup mode，even if XZ-DT25H enters setup mode it will exit when it does not have any command actions at continuous 60S.
Standard accessories:
