Installing the UC-2200A
DIN-rail Mounting
The stainless-steel DIN-rail mounting plate comes attached to the
product’s casing (the specification for the screws is M3 x 6 mm). To
mount the UC-2200A on to a DIN rail, make sure that the stiff metal
spring is facing upwards and follow these steps.
1. Insert the top of the DIN rail into the slot
just below the upper hook of the DIN-rail
bracket.
2. Latch the unit firmly onto the DIN rail as
shown in the illustrations below:

Wall Mounting (optional)
The UC-2200A can be mounted using a wall-mounting kit, which needs
to be purchased separately. Follow these steps to mount the computer
on to a wall:
Step 1: Use four screws (M3 x 4
mm)
to fasten the wall-mounting
brackets on the
left panel of the
computer.
Step 2: Use another four screws
(M3 x
6 mm) to mount the
computer on a wall or a cabinet.
Connector Descriptions
Power Connector
Connect the power jack (in the package) to the UC-2200A’s DC
terminal block (located on the top panel), and then connect the power
adapter. It takes about 30 seconds for the system to boot up. Once the
system is ready, the Power LED will light up.
ATTENTION
The wiring for the input terminal block should be installed by a
skill
ed person. The wire type should be copper (Cu), wire size
should be
14 to 16 AWG, and a torque of 0.19 n-m should be
used for V+, V
-, and GND connections. The wire size of the
power input and earthing conductor should be the same.
WARNING
The product is intended to be supplied by a UL Listed Power
Unit marked "L.P.S." (or "Limited Power Source") and is rated
12
to 24 VDC, 0.9 A min., Tma = 75°C (min). If you need
further help with purchasing the power source, please contact
Moxa for further information.
WARNING
The means of power cord of adapter should be connected to a
socket-outlet with earthing connection.

WARNING
EXPLOSION HAZARD!
Do not disconnect equipment unless the power has been
removed or the area is known to be non-hazardous.
Grounding the UC-2200A
Grounding and wire routing help limit the effects of noise due to
electromagnetic interference (EMI).
SG: The Shielded Ground (sometimes called
Protected Ground) contact is the
right-most
contact
of the 3
-pin power terminal block connector when
viewed from the angle shown here. Connect the SG
wire to an appropriate grounded metal surface.
Ethernet Ports
The two 10/100/1000 Mbps Ethernet ports (LAN 1 and LAN 2) come
with RJ45 connectors. The pin diagram of the ports is given below:

Micro SD/SIM Card Sockets
The UC-2200A comes with a Micro SD socket for storage expansion and
a SIM card socket for cellular communication. The Micro SD card and
SIM card sockets are located on the lower part of the front panel. To
install the cards, remove the screw and the protection cover to access
the sockets and insert the Micro SD card or the SIM card into the
sockets. Make sure you insert the cards in the correct direction. Refer
to the instructions above the socket. You will hear a click when the
cards are in place. To remove the cards, push the cards in before
releasing them.
Console Port
The console port is an RS-232 port that can be connected to a 4-pin pin
header cable. You can use this port for debugging or firmware upgrade.
The console port is located on the top panel of the device and is
accessible after removing the cover of the slot.

USB Port
The USB 2.0 port is located at the lower part of the front panel. By
default, the USB auto-mount is disable. If enabled, the USB storage is
mounted at /media/USB_P1 /media/USB_P2.
Antenna Connectors
There are three antenna connectors on
the front panel of the UC
-
2200A. W1 and
W2 are for cellular modules.

Real-time Clock
The real-time clock in the UC-2200A is powered by a lithium battery.
We strongly recommend that you do not replace the lithium battery
without the help of a Moxa support engineer. If you need to change the
battery, contact the Moxa RMA service team.
ATTENTION
There is
a risk of explosion if the battery is replaced with an
incorrect type
of battery. Replace only with the same or
equivalent type recommended by the manufacturer.
Dispose of used batteries according to the manufacturer’s
instructions.
Placing a Round Sticker on a Screw
Three round stickers are included in the product package. Stick one of
them on to an external screw as indicated in the figure below to help
detect unauthorized access and tampering.
Follow these steps to place the stickers.
1. Use a cloth to clean the surface of the screws with a 75% alcohol
solution.
2. Use a tweezer to place the stickers.
3. Press the sticker down on to the screw with 15 psi (pound/square
inch) pressure for at least 15 seconds.
4. Keep the device at room temperature for 24 hours before
deploying the devices in harsh environments.
NOTE
1. Place the stickers carefully as they are thin and fragile.
2.
The ideal environment for the stickers to be stored in is
22°C (72°F) and 50% relative humidity.
3.
Keep the extra two stickers in a safe place so that only
authorized persons can access them.
