Remark ：

1, radio power supply requirements: The maximum output current is not less than 3A, and the linear DC power supply is the best choice. If using switching power supply, the power supply with smaller ripple and better EMC characteristics should be selected.

2, the radio must be connected the antenna before the radio is powered on, a long-time antenna open-circuit working may cause damage to the radio.

3, The radio shell is used for heat dissipation. When working do not touch the radio with hands to avoid the scald.

XZ-DT25-MXX 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 needed Rx and Tx frequency 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-DT25 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-DT25 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-DT25 current working parameters

1.7 Exit Setup Mode

Format     >E

Return     OK

XZ-DT25  exit setup mode，even if XZ-DT25 enters setup mode it will exit when it does not have any command actions at continuous 60S.
