4. Source setting
Press Sources to enter the source setting menu.
Set the Tx source and the threshold
Press Tx and rotate the multifunction knob to select the desired
channel, and then press down the knob. You can also press Tx
continuously or enable the touch screen to select it. The available
channels include OFF, CH1-CH2, and D0-D15.
When you select the analog channel (CH1-CH2), press Threshold,
then rotate the multifunction knob
or use the pop-up numeric
keypad to adjust the threshold of Tx source. When you modify the
threshold of the Tx source channel, a dotted line displaying the current
threshold level is displayed on the screen. The dotted line disappears in
about 2 s after you stop modifying the threshold.
Set the Rx source and the threshold
Use the same method to select the Rx source and set the threshold (only
when the Rx source channel is set to an analog channel (CH1-CH2)).
Note: The Tx and Rx source channels cannot be set to "OFF" at the same time.
Polarity
Press Polarity continuously to select the polarity of data transmission. It
can be set to "
" (positive) or " " (negative).
Normal: Use negative logic. High level indicates logic "0"; low level
indicates logic "1".
Invert: Use positive logic. High level indicates logic "1"; low level
indicates logic "0".
5. Set data package
Press Settings to enter the data package setting menu.
Data
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.
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
