Mode-S Beast:Data Input Formats
The DIP switches are read during startup and taken as a default. Later they can be overwritten by software commands. Anyway, if then a DIP is changed to a position that is different to the pervious settings (by either hardware or software), the new setting takes account.
The software commands are the same in each output mode.
The input format is similar to the binary output format and allows control of DIP#3 until DIP#10 since baudrate setting does not make any sense over a serial interface. All commands start with a sequence
<esc> "1" <esc> is 0x1a, and "1" is 0x31
The next character sets or resets a DIP switch:
|DIP||Bit||Function||OFF, open = lower case characters||ON, closed = upper case characters|
|1,2||-||Baudrate||not supported||not supported|
|3||0||Output Format AVR/Binary||"c"||"C"|
|4||1||DF-11/17 only filter||"d"||"D"|
|5||2||MLAT info (AVR only)||"e"||"E"|
|6||3||CRC check disable||"f"||"F"|
|7||4||Mode-S Beast classic:
DF0/4/5 masking filter
Legacy 12MHz Timestamp/
|8||5||RTS handshake off/on||"h"||"H"|
|9||6||FEC disable yes/no||"i"||"I"|
|10||7||Mode-A/C enable on/off||"j"||"J"|
Note: Months after the binary format was introduced, I got noticed that in ASCII <esc> is encoded as 0x1b. I actually wanted to use this code, but unfortunately only implemented my believes. For compatiblity reasons this will now stay as 0x1a and not be changed.
Note: Setting 'g/G' is beeing used for GPS timestamp setting on the Radarcape
