RS485 PC Connection (4-pin Connector)
Note
If
the
RS485
cable
is
too
long,
the
signal
may
be
weakened.
In
this
case,
you
should
install
a
terminating
resistance
at
both
ends
of
the
bus
by
turning
on
the
Dip
Switch
for
normal
signal
transmission
On
the
other
hand,
if
the
cable
is
too
short,
the
resistance
may
interrupt
signal
transmission.
Therefore,
by
considering
the
length
of
the
cable
and
the
signal
status,
select
whether
to
turn
on
or
off
the
terminating
resistance
switch.
Caution!
-
Only the devices at the both ends of the bus should be terminated.
-
If you do not connect GND, the RS485 chip may be damaged or communication may not be successful.
