Command List:
 :DECoder<n>:UART:TX
 :DECoder<n>:UART:RX
 :DECoder<n>:UART:POLarity
 :DECoder<n>:UART:ENDian

:DECoder<n>:UART:TX
Syntax :DECoder<n>:UART:TX <tx>
:DECoder<n>:UART:TX?
Description Set or query the TX channel source of RS232 decoding.
Parameter
Name
Type
Range
Default
<n> Discrete {1|2} --
<tx> Discrete {CHANnel1|CHANnel2|OFF} CHANnel1
Explanation When OFF is selected, no TX channel source will be set. The TX channel source and RX
channel source (
:DECoder<n>:UART:RX) cannot be both set to OFF.
Return
Format
The query returns CHAN1, CHAN2, or OFF.
Example
:DECoder1:UART:TX CHANnel2 /*Set the TX channel source to CH2*/
:DECoder1:UART:TX? /*The query returns CHAN2*/
:DECoder<n>:UART:RX
Syntax :DECoder<n>:UART:RX <rx>
:DECoder<n>:UART:RX?
Description Set or query the RX channel source of RS232 decoding.
Parameter

--
<rx> Discrete {CHANnel1|CHANnel2|OFF} OFF
Explanation When OFF is selected, no RX channel source will be set. The RX channel source and TX
channel source (
:DECoder<n>:UART:TX) cannot be both set to OFF.
