RS232
:SBUS:RS232:BAUDrate
Command format：

:SBUS:RS232:BAUDrate <baudrate>
:SBUS:RS232:BAUDrate?
Functional description：

This command is used to set RS232 decoding baud rate of the oscilloscope. Parameter is integer, range is
120~5000000.
Return format：

Query returns baud rate.
For example：

:SBUS:RS232:BAUDrate 500
:SBUS:RS232:BAUDrate?
:SBUS:RS232:BITorder
Command format：

:SBUS:RS232:BITorder {LSBFirst | MSBFirst}
:SBUS:RS232:BITorder?
Functional description：

This command is used to set RS232 bus decoding bit order of the oscilloscope, which includes LSBFirst
and MSBFirst.
Return format：

Query returns {LSBFirst | MSBFirst}.
For example：

:SBUS:RS232:BITorder LSBF
:SBUS:RS232:BITorder?
:SBUS:RS232:SOURce
Command format：

:SBUS:RS232:SOURce {CHANnel1|CHANnel2|CHANnel3|CHANnel4|<Dx>}
:SBUS:RS232:SOURce?
Functional description：

This command is used to set RS232 bus decoding source.
<Dx>: It presents the oscilloscope has LA function and it can set D0-D15 channel as the bus decoding source.
Return format：

Query returns {CHANnel1|CHANnel2|CHANnel3|CHANnel4|<Dx>}.
For example：

:SBUS:RS232:SOURce CHANnel1
