Tip
When the current trigger type is "RS232", performing the copy operation at any
time can quickly apply the current RS232 trigger setting (the specified parameters)
to RS232 decoding. Then, you can still set the RS232 decoding parameters
according to the introductions below.
3. Set the TX and RX sources
Set the TX source

Press TX; turn the multi-function knob
channel and press the knob. You can also press TX continuously to switch
the current source channel. You can select D0 to D15 or CH1 to CH4. When
"None" is selected, no TX source channel will be set.
When an analog channel (CH1 to CH4) is selected, you can press TX and
turn the multi-function knob
of the TX source channel. Pressing the multi-function knob
reset the threshold of the channel to 0 V.
When modifying the threshold of the TX source channel, a dotted line
displaying the current threshold level is displayed on the screen (in the
same color as the channel). It disappears in about 2 s after you stop
modifying the threshold.
Set the RX source

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-CH4)).
Note: The TX and RX source channels cannot be set to "None" at the same
time.
4. Specify the baud rate
Press Baud and turn the multi-function knob
The default is 9600 bps. You can also press Baud continuously to switch the
current baud rate. You can select a preset baud rate or "User".
