Adjustable pull up/down resistor for RS-422/485 (150
K
Ω
or 1 K
Ω
)
Dip switch Pin 1 and Pin 2 are
used to set the pull up/down
resistors. The default is 150
KΩ.
Turn on dip switch Pin 1
and Pin 2 to set this value to 1
KΩ. Do not use the KΩ setting
with RS-232 mode, since
doing so will degrade the
RS-232 signals and shorten
the communication distance.
Dip switch Pin 3 is used to set
the terminator. Turn on dip
switch Pin 3 to set this value to
120 ohm.
Hardware Installation Procedure
STEP 1
: Connect the 12-48 VDC power adapter to the NPort 6450 and
then plug the power adapter into a DC outlet.
STEP 2
: For first-time configuration, use a cross-over Ethernet cable to
connect the NPort 6450 directly to your computer’s Ethernet cable. For
connecting to a network, use a standard straight-through Ethernet cable
to connect to a hub or switch.
STEP 3
: Connect the NPort 6450’s serial port(s) to serial device(s).
NOTE
The operating temperature of the power adapter in the box is 0 to
40˚C. If your application is out of this range, please use a power
adapter supplied by UL Listed External Power Supply (The power
output meets SELV and LPS and rated 12 - 48 VDC, minimum
0.73A). Moxa has power adapters with wide temperature range
(-
40 to 75˚C,
-
40 to 167˚F), the PWR
-12150-(plug type)-SA-T
series, for your reference.
