6)Software Function Setting

6.1 Enter setup mode

Continues to send 3 + numbers at current baud rate, XZ-DT254 enters setup mode, and the serial port outputs OK at this time

Format + + +

Return OK

6.2 Set Channel 0 Frequency

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;

XZ-DT254 receiving and transmitting frequency range:420 ~ 480MHz, the same XZ-DT254 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.

6.3 Baud Rate Setting

Format >WBA

Return <Com_Rate:1200

Explain >WB means interface baud rate

A~E means 1200~19200bps;A=1200、B=2400、C=4800、D=9600、E=19200

6.4 Parity Bits Setting

Format >WVN

Return <Verify:8N1

Explain >WV means Interface Parity Bit

N、E、O means 8N1、8E1、8O1

6.5 Emission Power Level Setting

Format >WP3

Return <Tx Power:3

Explain > WP means writing power level

1、2、3 means 0.5W、1W、2W

6.6 Read all Parameters Command

Format >WP3

Return <Channel_0:RX:453.25000/TX:453.25000

<Com_Rate:1200

<Verify:8N1

<Tx Power:3

Explain Output XZ-DT254 current working parameters

6.7 Exit Setup Mode
