2. Touch Decode and select the desired slot (Decode1 or Decode2).
3. Touch Protocol and then select UART by turning Universal Knob.
4. Touch Signal to enter the SIGNAL menu as below shows.
5. Set RX:
a. Touch RX to select the channel that is connected to the RX signal.
b. Touch rst Threshold key to set the RX signal’s threshold voltage level by Universal Knob. The threshold
voltage level is for decoding, and it will be regard as the trigger voltage level when set the trigger type to serial.
6. Set TX:
a. Touch TX to select the channel that is connected to the TX signal.
b. Touch second 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 regard as the trigger voltage level when set the trigger type to serial.

• If the desired baud rate is not listed, press the Baud and select custom option, press the Custom and turn the
Universal Knob to set the desired baud rate.
10. Touch Data Length and set byte bits (5-8) by Universal Knob.
11. Touch Parity Check to set the type of parity check (Even, Odd, Mark, Space or None).
12. Touch Stop Bit to set the length of stop bit (1, 1.5 or 2 bits).
13. Touch Next Page softkey.
14. Touch Bit Order to select the bit order (LSB or MSB).
15. Touch Idle Level to set the idle level (LOW or HIGH).
