2 Pin Definitions

3 Working Frequency

The DIP switch can select 0~16 channels, and frequency point of 1~15 channels is fixed, and the frequency of the 0 channel can be set and saved arbitrarily through our software. Dial switch to "ON", means "1", dial "OFF" means "0", "1 is high" and "4" is "low.

4 Software Function Setting

4.1 Enter setup mode

Continues to send 3 + numbers at current baud rate, XZ-DT254H enters setup mode, and the serial port outputs OK at this time

Format    + + +

Return     OK

4.2 Set Channel 0 Frequency

Format     >WF0/RX:453.25000/TX: 453.25000

Return    

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；

XZ-DT254H receiving and transmitting frequency range：420 ~ 480MHz, the same XZ-DT254H 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.

 4.3 Baud Rate Setting

Format     >WBA

Return    

Explain     >WB means interface baud rate

A~E means 1200~115200bps；A=1200、B=2400、C=4800、D=9600、E=19200、F=38400、H=115200                                                                                                                                                     4.4 Parity Bits Setting

Format    >WVN

Return   

Explain    >WV means Interface Parity Bit

N、E、O means 8N1、8E1、8O1

4.5 Emission Power Level Setting

Format   >WP3

Return   

Explain   > WP means writing power level

1、2、3 means 0.5W、1W、2W

4.6 Read all Parameters Command

Format     >WP3

Return    

Explain   Output XZ-DT254H current working parameters

4.7 Exit Setup Mode

Format     >WE

Return     OK

XZ-DT254  exit setup mode，even if XZ-DT254H enter setup mode it will exit when it does not have any command actions at continuous 10S.
