| Baud is symbols per second, bps is bits per second. Where baud=bps, that means each symbol carries 1 bit (i.e. a symbol can have two states, 0 or 1). Where baud is 2x bps, that means each symbol carries 2 bits (i.e. a symbol can have four states: 00, 01, 10, 11). | Baud is symbols per second, bps is bits per second.

| + | * the first two digits the board version (a decimal number, e.g. 04) | ||
| + | * the next two are the physical MODE switch setting (encoded as binary, for example 06 is 0110) | ||
| + | * the last four are the operating mode | ||
| + | |||
| + | For example, for a value of '' | ||
| + | |||
| + | * Board Revision 04 | ||
| + | * MODE switch setting 1111 (set by SETHW hardware command) | ||
| + | * Current Operating Mode 0x23 (MODE_300_AFSKPLL_IL2P_CRC) | ||
| + | |||
| + | The Operating Mode values are **internal** and **may change with firmware version**, so you can use the following table to map the operating mode values **for Version .44 of the Firmware** (current at time of writing): | ||

| + | ^ Switch Mode ^ BrdSwchMod Value ^ Mode Name ^ | ||
| + | | 0 (0000) | ||
| + | | 1 (0001) | ||
| + | | 2 (0010) | ||
| + | | 3 (0011) | ||
| + | | 4 (0100) | ||
| + | | 5 (0101) | ||
| + | | 6 (0110) | ||
| + | | 7 (0111) | ||
