Press Data and rotate the multifunction knob to set the number of
data bits actually contained in each frame of data. Press down the knob to
select it. You can also press Data continuously or enable the touch screen
to select it. The available data bits are 5 bits, 6 bits, 7 bits, 8 bits, and 9 bits.
âš« Parity
It is used to check whether the data transmission is correct. Press Parity
and rotate the multifunction knob to select the desired parity mode,
then press down the knob to select it. You can also press Parity
continuously or enable the touch screen to select it.
➢ 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.
âš« Stop Bit
Press Stop Bit and rotate the multifunction knob to set the stop bits
after each frame of data. Press down the knob to select it. You can also

be set to 1 bit, 1.5 bits, or 2 bits.
âš« Endian
Press Endian to select "LSB" or "MSB". By default, it is "LSB".
LSB: indicates Least Significant Bit transmission sequence, i.g. the lowest
bit of the data is transmitted first.
MSB: indicates Most Significant Bit transmission sequence, i.g. the highest
bit of the data is transmitted first.
LSB MSB
âš« Package
