- Weight: 100g/0.2lb
- PL2303 can connect with a computer and provide a communication protocol


  1: Characteristics of LMX2820 chip:

PC communication protocol for RF signal source:

The overall structure of the PC protocol adopts the command line mode, and the communication baud rate is 115200bps. A PC issues commands, which are parsed and executed locally, and then the result is returned to the PC. Commands are limited to lowercase letters a~z and numbers 0~9. The ending symbol of each command is the "#" symbol (hexadecimal representation is "0x23"), and the total length of PC commands is up to 15 characters (including "#").

5.1. W command (host computer to send data to the main control board)

5.1.1. WC command: set frequency value, start frequency, stop frequency and step frequency

The format is: wcxx xxx xxx#, a total of 11 bytes; where "c" is a different frequency value

W1: write start frequency;

W2: write stop frequency;

W3: write step frequency;

"xx xxx xxx" is the frequency value represented by 8 digits. For example: 01 000 000 means that the set frequency is 01 000 000KHz (1GHz);

5.1.2. Start command: The main control board starts data scanning and transmits data to the host computer in real time

* The format is: start#, a total of 6 bytes;

5.1.3 Stop command: Stop scanning

* The format is: stop#, a total of 5 bytes;

5.1.4 WP command: Amplitude value command

The format is: wpxxxx #, a total of 7 bytes; "xxxx" is the amplitude factor represented by the 4 ASII (only the last 2 digits are used), and there is no need to convert the dbm value or decimal point, just send the value down. The range is 00-63 (unitless, just an amplitude factor)

wp0001 The lower computer shows P=02

wp0010 The lower computer displays P=10

5.1.5 ti command: scanning time command (max. 9999)

The format is: tixxxx #, a total of 7 bytes; where "xxxx" is the amplitude value represented by the 4 ASII digits. For example:

0001 indicates that the scanning time is set to 1mS (fastest scanning time, step one frequency point);

0010 means that the set scanning time is 10mS;

1000 means that the set scanning time is 1S;

0022 means that the set scanning time is 22mS;

5.2 The host sends data to the host computer (response value)

* Returns "OK$" after receiving the correct data
