2BA39HX-DU1022DWireless date transceiver

HX-DU10 22D Common AT Command Operation Instructions 1, Th e methods of entering and exiting the radio parameter configuration mode of HX-DU1022D 400M. (1), method 1: CONFIG configuration pin (46 pin) Setting the CONFIG pin to low level, the radio will enter the configuration mode; setting the Config pin to the high level, and the radio will exit the configuration mode (ie entering the normal working mode of the system); (2), method 2: sending the string +++ and ATA commands Sending the string +++ the radio will enter the configuration mode; (Note: it must be sent as follows, 1 second before the string "+++" sent, no characters can be sent; after the string "+++" sent, No characters can be sent after 1 second, otherwise the system cannot enter the radio parameter configuration mode; there is no carriage return line feed (\r\n) after the string; Sending the ATA command the radio will exit the configuration mode; 2, HX-DU1022D commonly used AT command (1), AT&W It is the parameter saving command. Note: If you want the parameter to be saved when powered off, you must first send this AT&W command to save the parameters. After the command is successfully sent, it will return to the prompt OK. (2),ATP0=CH TX RX It is The 400M fixed frequency working frequency table configuration E.g: ATP0=00 450.125 450.125 It is Indicated that the transmitting frequency of channel 0 is 450.125MHZ and the receiving frequency is 450.125MHZ. If you want to configure multiple channels, just follow the steps below: ... ... ... Note: The frequency and the channel number are separated by a space character (only one space symbol); (3)、ATP0? Query the working frequency table that the current station has configured of 400M fixed frequency. E.g: (4)、AT&V Query current radio operating parameters (5), Modify the current serial port baud rate ATS102=value The value is as follows: 1-115200; 2-57600; 3-38400; 5-19200; 7-9600; Special Note: After sending this command, the serial port baud rate will take effect immediately. If you want to save the current configuration parameters, you need to switch the serial port baud rate of the current configuration tool, and then send the AT&W saved command. For example: change the current serial port baud rate to 9600, as follows: (1). ATS102=7 (2). Switch the serial port baud rate of the configuration tool to 9600; (3). Send an AT&W saved command; (6), Modify the wireless baud rate ATS103=value The value is as follows: 0-4800; 1-8000; 2-9600; 3-16000; 4-19200; Remarks: The protocols of TRANSEOT and TRIMTALK support both wireless baud rates of 4800 and 9600, and TRIMMM3 only supports 19200 wireless baud rate; (7), Modify the transmission power ATS108=value The value is as follows: H: high power; L: low power; (8), Set the current radio work transmission channel ATS131=value Value range: 0-63 (9), Set the current radio work receiving channel ATS132=value Value range: 0-63 (10), Select the communication protocol ATS186=value The value is as follows: 1-TRIMTALK; 2-TRIMMK3; 4-TT450S; 5-TRANSEOT 11-HITARGET (11), AT&F53 It is the default configuration of the TRANSEOT protocol. The default configuration of the current radio operating parameters is as follows: S102=1; The serial port baud rate is 115200 S103=2; The wireless baud rate is 9600; S108=H; The transmitting power is high S131=00-xxx.xxxxx; The current sending channel is 0. For the frequency, check the frequency table configured by the ATP0 command, and the corresponding 0 channel is the sending frequency. S132=00-xxx.xxxxx; The current receiving channel is 0. For the frequency, check the frequency table configured by the ATP0 command, and the corresponding 0 channel is the receiving frequency point. S186=05; TRANSOSOT protocol; S127=0; 400M fixed frequency mode (band can only be queried in this command) (12), AT&F54 It is the default configuration of the TRIMTALK protocol. The default configuration of the current radio parameters is as follows: S102=1; The serial port baud rate is 115200 S103=2; The wireless baud rate is 9600; S108=H; The transmitting power is high; S131=00-xxx.xxxxx; the current sending channel is 0.
