5.5.1 Set UART Baud Rate or Set Baud Rate

Table 5-69. Format
Firmware Version 1.0	Firmware Version 1.2 and Later
`SB,<hex8>[,<00-01>,<00-03>,<00,01>]`	`SBR,<hex8>[,<00-01>,<00-03>,<00,01>]`
Note: All firmware version 1.0 syntax remains valid in version 1.2 and later.

This command sets the baud rate of the UART communication. The user can query the existing configuration values using the GB command. The input parameter is an 8-bit hex value in the range of 00-0B, representing baud rate from 2400-921600 (see the following table). The SB or SBR command also supports three optional parameters to configure the UART parity and stop bits.

The first parameter sets the desired baud rate.
The second parameter decides to Enable/Disable parity.
Use the third parameter to set the Parity mode (see Table 5-72).
The fourth parameter sets the desired stop bits.

Table 5-70. UART Baud Rate Settings
Setting	Baud Rate
00	921600
01	460800
02	230400
03	115200
04	57600
05	38400
06	28800
07	19200
08	14400
09	9600
0A	4800
0B	2400

The second parameter is used to enable or disable the parity check (see the following table).

Table 5-71. UART Parity Check Settings
Setting	Parity Check
00	Disable
01	Enable

The third parameter is used to select the Parity mode (see the following table), which works only after enabling the parity check.

00	Odd
02	Even

Item	Firmware Version 1.0 and Later	Description
Default:	`03`
Example:	`SB,07`	Set the UART baud rate to 19200
	`SB,04,01,02,00`	Set the UART baud rate to 57600
		Enable the parity check as Even mode
		Set the stop bits to 1 bit
Response:	`AOK`	Success
Response:	`Err`	Syntax error or invalid parameter
Note: The PDS stores these parameters. The parameters are effective after reboot.
