UART/RS232 Triggering and Serial Decode
The three steps to set up the UART / RS232: “ Setup for UART/RS232 Signals”,
“UART/RS232Triggering ” and “ UART/RS232 Decode ” to trigger and decode the
signals.
Setup for UART/RS232 Signals
1. Press the Decode key to enter the DECODE function menu.
2. Press the Decode softkey and select the desired decoder (Decode1 or Decode2).
3. Press Protocol softkey and then select UART by turning the Universal Knob.
4. Press Signal softkey to enter the SIGNAL menu as in Figure 47 below.

5. Set RX:
1) Press RX to select the channel that is connected to the RX signal.
2) Press the Threshold key to set the RX signal’s threshold voltage level
using the Universal Knob. The threshold voltage level is for decoding, and
it will be used as the trigger voltage level when setting the trigger type to
serial.
6. Set TX:
1) Press TX to select the channel that is connected to the TX signal.
2) Press first Threshold key to set the TX signal’s threshold voltage level by
Universal Knob. The threshold voltage level is for decoding, and it will be
regarded as the trigger voltage level when set the trigger type to serial.
7. Press softkey to return previous menu.
8. Press the Configure softkey to enter BUS CONFIG menu.
