Software Programming

1.1 Enter setup mode

Hardware: connect the 8th foot with Ground and green led keeps lighting, the module enters setup mode, serial port rate is 9600 8N1

Software: at the current baud rate, 3 + numbers are sent continuously, XZ-DT78 enters 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 of writing channel 0

RX: means receiving frequency 453.25000 MHz, please notice frequency needs be accurate to 5 digits after the decimal point；

TX: means transmitting frequency 453.25000 MHz, please notice frequency needs be accurate to 5 digits after the decimal point；

The same XZ-DT78 receiving and transmitting frequency setup can be the same or different, but modules in the same communication system must have the same receiving and transmitting frequency. Dip Switch can only set frequency in Channel 0.

1.3 Interface Baud rate setup

Format >WBA

Return <Com_Rate:1200L

Explain >WB means writing interface baud rate

A~E means1200~9600bps；A=1200L, B=1200H, C=2400, D=4800, E=9600

Remark：A=1200L,1200 interface,240bps air transmission, the longest distance communication.

1.4 Parity Bits Setup

Format >WVN

Return <Verify:8N1

Explain >WV means Interface Parity Bit

N、E、O means 8N1、8E1、8O1

1.5 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-DT78 current working parameters

1.6 Exit Setup Mode

Format >WE

Return OK

XZ-DT78 exit setup mode, if XZ-DT78 enters setup mode it will exit when it does not have any command actions at continuous 60S.
