RX in (for setting baud rate only) SS pin goes high when Key pressed, low when released; Configuration. The USB Host board will generate ASCII characters at the following baud rates. 2400; 4800; 9600 (default) 14400; 19200; 31250; 38400; 57600; 115200; The default baud rate is 9600. Configuration can be done by sending commands via the serial port.
RS232 is a standard protocol for used for serial communication, it is used for connecting computer and its peripheral devices to allow serial data exchange between them. Baud rate is used to measure the speed of transmission. It is described as the number of bits passing in one second.Sep 21, 2013 · Go to the PORT option. Here you can set the Baud rate, number of stop bits, parity, Number of data bits and PORT. Set the baud rate whatever you like, but don’t select too high baud rates, because higher baud rates sometimes cause errors. Select at max 115200. Choose your COM port (in this case, choose 3 since your device is connected to COM3 ...
The UC232A USB-to-RS232 serial port converter is the ideal accessory for laptop and desktop computers that do not have a COM or DB9 serial port. Supporting both PC and Mac systems with baud rates up to 921.6 Kbps for rapid performance, it offers a convenient connectivity solution for industrial automation systems, scientific instruments, point ... The above diagram also shows the RS232 timing diagram where each bit period is 1/frequency so for a baud rate of 9600 bps (bits per second) the period of each bit is 1/9600 or 104.166us this is effectively the RS232 clock period required for the specific baud rate in use.
