Pull-high/low Resistors and Termination Resistor
for RS-422/485
You may need to set the pull
-
high/low resistors when
the
termination
resistors are used in
certain RS
-422 or RS-485
environments.

S5 is for the NPort W2250A-W4 only.
NOTE
Do not use the 1 k
Ω setting while in RS-232 mode. Doing so
will degrade the RS
-232 signals and reduce the effective
communication distance.
