3. Hardware Introduction
Reset Button—Press the Reset button continuously for 5 sec to
load factory defaults: Use a pointed object, such as a straightened
paper clip or toothpick, to press the reset button. This will cause
the Ready LED to blink on and off. The factory defaults will be
loaded once the Ready LED stops blinking (after about 5 seconds).
At this point, you should release the reset button.

Strength
Green The signal quality is indicated by the number
of LEDs that are lit; 4 LEDs indicates
maximum signal strength.
Adjustable pull high/low resistor for RS-422/485
(150 KΩor 1 KΩ)
Jumpers are used to set the pull
high/low resistors. The default is
150 KΩ. Short the jumpers to set
th is value to 1 KΩ . Do no t use the
KΩ setting with RS
since doing so will degrade the

4. Hardware Installation Procedure
STEP 1: Connect the 12-48 VDC power adaptor to the NPort 6450
and then plug the power adaptor 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.
