: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
Name
<n>
<rx>
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.
Return The query returns D0, D1, D2, D3, D4, D5, D6, D7, D8, D9, D10, D11, D12, D13, D14,
Format D15, CHAN1, CHAN2, CHAN3, CHAN4, or OFF.
Example :DECoder1:UART:RX CHAN4
:DECoder1:UART:RX?
:DECoder<n>:UART:POLarity
Syntax :DECoder<n>:UART:POLarity <pol>
:DECoder<n>:UART:POLarity?
Description Set or query the polarity of RS232 decoding.
Parameter
Name
<n>
<pol>
Explanation
NEGative: negative polarity (

RS232 standard uses negative polarity.
POSitive: positive polarity (

Return The query returns NEG or POS.
