Hi, I am connecting a mobile equipment to RS232.
On the board of mobile equipment has a 3.579Mhz Oscillator.
when I run the software (which come along with mobile equipment), I choose [9600 bps 3.57MHZ] as the speed to communicate with the board.
The full list of speed I can choose are
9600 bps 3.57MHz
10472 bps 3.89 MHz
11520 bps 4.28 MHz
12800 bps 4.76 MHz
14400 bps 5.35 MHz
16457 bps 6.12 MHz
19200 bps 7.14MHz
But only [9600 bps 3.57MHz] works. The rest cann't communicate with the board.
My question is:
What is the relationship between bps and Hertz?
