Hardware Installation Procedure
Panel/Wall Mounting
Mounting the NPort 5000AI-M12 on the wall requires three screws. Please
use the three screws provided in the product package.
STEP 1: Use the device to mark the positions of the three screw holes on
the wall, as shown in the mounting dimensions diagram.
STEP 2: Use one screw to go through the top-middle screw hole on the
device server and screw it into the wall.
STEP 3: Screw in the remaining two screws through the bottom-left and
bottom-right holes on the device server to the wall.
NOTE
Please use the screws (M3 x 40 mm) included.
DIN-Rail Mounting (optional)
You may use the optional DIN-rail mounting kit (DK-TN-5308; must be
purchased separately) to mount the NPort 5000AI-M12 on a 35 mm DIN
rail.
STEP 1: Fix the DIN-rail attachment plate onto the rear panel of the
device server as shown in the figure below.

STEP 2: Position the NPort 5000AI-M12 on the DIN rail and tilt it to hook
the clamps over the top edge of the rail.
STEP 3: Swing the device server down onto the DIN rail until both clamps
latch on completely.

Software Installation Information
For the NPort’s configuration, the default IP address of the NPort is: LAN:
Static IP = 192.168.127.254; netmask = 255.255.255.0
You may log in with the password moxa to change any settings to meet
your network topology (e.g., IP address) or serial device (e.g., serial
parameters). If you would like to apply the Real COM mode to your
application, you will need to install the NPort’s driver on your desktop.
You may also refer to Moxa’s support website
https://www.moxa.com/support for the user’s manual, driver, SNMP MIB,
and NPort Search Utility.
NOTE
For the NPort with DB Male serial ports, you may refer to the DB9
Male Ports pin assignment section to loop back pin 2 and pin 3 for
the RS-232 interface.
