15.2.2 To Set Data Package
Data
Click or tap the drop-down button of
Data to select the data bits. The available data
bits are 5 bits, 6 bits, 7 bits, 8 bits, and 9 bits.
Parity
It is used to check whether the data transmission is correct. Click or tap the drop-
down button of
Parity to select the desired parity mode.
• None: indicates that no check bit appears during the transmission.
• Even: indicates that the total number of "1" in the data bit and check bit is an
even number. For example, when 0x55 (01010101) is sent, "0" should be added
to the check bit.
• Odd: indicates that the total number of "1" in the data bit and check bit is an
odd number. For example, when 0x55 (01010101) is sent, "1" should be added to
the check bit.
Stop Bit
Click or tap the drop-down button of
Stop Bit to set the stop bits after each frame of
data. It can be set to 1 bit, 1.5 bits, or 2 bits.
Endian
Click or tap the drop-down button of
Endian to select the desired endian.
• LSB: indicates Least Significant Bit transmission sequence, i.e. the lowest bit of
the data is transmitted first.
• MSB: indicates Most Significant Bit transmission sequence, i.e. the highest bit of
the data is transmitted first.
