Parity:
A means of checking the correctness of a character by adding an extra bit to the character and setting
the value based on all the other bits in the character.
•
StopBits:
The number of bits used to indicate the end of the character.

Device Range/Type
drop-down. Click
Apply Settings
when done.
6.3.1.1
4-20 mA Device Connection
An input channel configured for 0-24 mA can measure the output of a 4-20 mA device. The Current Loop
interface measures the current into the selected input by converting it to a voltage measurement across
a fixed 49.9-ohm resistor.
