:BUS<n>:RS232:RX?
Description
Set or query the RX channel source of RS232 decoding on the specified bus.
Parameter
Name Type Range Default
<n> Discrete {1|2} --
<source> Discrete {CHANnel1|CHANnel2|OFF} OFF

When OFF is selected, no RX channel source will be set. The TX channel source and RX channel source
cannot both be set to OFF.

:BUS<n>:RS232:POLarity
Syntax
:BUS<n>:RS232:POLarity <pol>
:BUS<n>:RS232:POLarity?
Description
Set or query the polarity of RS232 decoding on the specified bus.
Parameter
Name Type Range Default
<n> Discrete {1|2} --
<pol> Discrete {POSitive|NEGative} NEGative
Explanation
The RS232 standard uses negative logic; namely high level is 0 and low level is 1. Therefore, when <pol>
is set to NEGative, the polarity is set to negative logic (namely "Normal" polarity); when <pol> is set to
POSitive, the polarity is set to positive polarity (namely "Invert" polarity).
Return Format
The query returns POS or NEG.
