Adjustable pull high/low resistor for RS-422/485 (150 K
Ω
or 1 K
Ω
)
JP6, JP7
for Port 2
JP4, JP5
for Port 1
Jumpers are used to set the pull
high/low resistors. The default is
150 K
Ω
. Short the jumpers to set
this value to 1 K
Ω
. Do not use the
K
Ω
setting with RS-232 mode,
since doing so will degrade the
RS-232 signals and shorten the
communication distance.
