Press and hold the function (FN) button between 7 to 9 seconds to reset the device to the factory default
settings. When the reset button is held down, the USR LED will blink once every second and become steady
after 7 to 9 seconds. Release the button within this period to load the factory default settings.
Real-time Clock
The real-time clock is powered by a non-chargeable battery. We strongly recommend that you do not
replace the lithium battery without help from a qualified Moxa support engineer. If you need to change the
battery, contact the Moxa RMA service team.
WARNING
There is a risk of explosion if the battery is replaced
with an incorrect type.

Installation Options
DIN-rail Mounting
The aluminum DIN-rail attachment plate is already attached to the product’s casing. To mount the device on
to a DIN rail, make sure that the stiff metal spring is facing upwards and follow these steps.
1. Pull down the bottom slider of the DIN-rail bracket located at the
back of the unit
2. Insert the top of the DIN rail into the slot just below the upper
hook of the DIN-rail bracket.
3. Latch the unit firmly on to the DIN rail as shown in the
illustrations below.
4. Push the slider back into place.
Wall Mounting (optional)
The device can be mounted on to a wall using a wall-mounting kit as shown in the following illustrations.
The optional wall-mounting kit is not included in the product package and should be purchased separately.
Follow these steps to mount the device on to a wall:
Step 1
Use four screws to fasten the wall
-mounting
brackets on the left panel of the
device.
Step 2
Use another four screws to mount the
device on a
wall or a cabinet.

AIG-300 Series HW UM Hardware Introduction

IMPORTANT!
The diameter of the screw heads should be greater than 7 mm and less than 14 mm; the diameter of the
shafts should be less than 3 mm. The length of the screws should be greater than 6 mm.
NOTE
•
Test the screw head and shank size by inserting the screws into one of the keyhole shaped apertures of
the wall-mounting plates before attaching the plate to the wall.
•
Do not drive the screws in all the way—leave a space of about 2 mm to allow room for sliding the wall
mount panel between the wall and the screws.

Wiring Requirements
In this section, we describe how to connect various devices to the AIG-300. Be sure to read and follow these
common safety precautions before proceeding with the installation of any electronic device:
•Use separate paths to route wiring for power and devices. If power wiring and device wiring paths must
cross, make sure the wires are perpendicular at the intersection point.
NOTE
Do not run signal or communication wiring and power
wiring in the same wire conduit. To avoid
interference, wires with different signal characteristics should be routed separately.
•You can use the type of signal transmitted through a wire to determine which wires should be kept
separate. The rule of thumb is that wiring that shares similar electrical characteristics can be bundled
together.
•Keep input wiring and output wiring separate.
•When necessary, it is strongly advised that you label wiring to all devices in the system.
ATTENTION
Safety First!
Be sure to disconnect the power cord before doing installations and/or wiring.
Electrical Current
Caution!
Calculate the maximum possible current in each power wire and common wire. Observe all electrical codes
dictating the
maximum current allowable for each wire size.
If the current goes above the maximum ratings, the wiring could overheat, causing serious damage to your
equipment.
Temperature Caution!
Be
careful when handling the unit. When the unit is plugged in, the inter
nal components generate heat, and
consequently the
outer casing may feel hot to the touch.
Connecting the Power
Connect the power jack (in the package) to the DC terminal block (located on
the top panel), and then connect the power adapter. It takes about
3 minutes
for the system to boot up.
Once the system is ready, the power LEDs
will light
up. Both models support
dual power inputs for redundancy.
WARNING
•
This product is intended to be supplied by a UL Listed Power Adapter or DC power source marked
“L.P.S.” (or “Limited Power Source”) rated 12 to 48 VDC, 1 A (minimum), and TMA = 85°C (minimum).
•
The power adapter should be connected to a socket outlet with an earthing connection.
If you need further information or assistance, contact a Moxa representative.

AIG-300 Series HW UM Hardware Connection Description
3-3
Grounding the Unit
There is a grounding connector on the top panel of the device. Use this connector to connect a well-
grounded mounting surface, such as a metal panel. Grounding and wire routing help limit the effects of
noise due to electromagnetic interference (EMI).
ATTENTION
A shielded power cord is required to meet the FCC emission limits
and to prevent interference with nearby
radio and television reception. It is essential that only the supplied power cord be used.
You are cautioned tha
t changes or modifications not expressly approved by the party responsible for
compliance could void your authority to operate the equipment.
Connecting to the Network
The Ethernet ports are located on the front panel of the device. The pin assignments for the Ethernet ports
are shown in the following figure. If you are using your own cable, make sure that the pin assignments on
the Ethernet cable connector match the pin assignments on the Ethernet port.
Pin 10/100 Mbps 1000 Mbps

Connecting to a USB Device
The device comes with a USB port located on the lower part of the front panel, allowing users to connect to
a device with an USB interface. The USB port uses a type-A connector.
Connecting to Serial Ports
The serial ports can be configured by software for RS-232, RS-422, or RS-485. The pin assignments for the
ports are shown in the following table:
