Data exchange with RigExpert antenna analyzers<\/h1>\n<\/div>\n
This description applies to RigExpert antenna analyzers.<\/p>\n
    \n
  1. Manually place the analyzer into the PC mode (or turn it on with USB cable connected to your PC).<\/li>\n
  2. Find the corresponding virtual COM port number. This port corresponds to the USB device with VID=0403 and PID=6001. Product descriptor of this device is the model of the analyzer (example: “RigExpert AA-230PRO”).<\/li>\n
  3. Open COM port with following parameters: 38400, 8N1.<\/li>\n<\/ol>\n

    All commands are not case-sensitive. Finish a line with either <CR> or <LF> (but not both). When a command is running, sending any character will abort it. Instead of a numerical value, “nan” (which stays for “not a number”) may be returned if the value cannot be evaluated.<\/p>\n
