Installing the UC-8112-ME-T
Two sliders are provided at the back of the unit for DIN-rail mounting or
wall mounting.
DIN-Rail Mounting
1. The DIN-rail mounting kit is mounted by default as shown in the
figure below:
2. Pull down the bottom slider of the DIN-rail bracket located at the
back of the unit
3. Insert the top of the DIN rail into the slot just below the upper hook
of the DIN-rail bracket.
4. Latch the unit firmly on to the DIN rail as shown in the illustrations
below.
5. Push the slider back into place.

Wall Mounting (optional)
ATTENTION
The wall-mounting kit is not included in the package and must be
purchased separately.
W
EXPLOSION HAZARD!
Do not disconnect equipment unless the power has been
removed or the area is known to be non-hazardous.
SG:
The Shielded Ground (sometimes called
Protected Ground) contact is the
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.
1. Remove the four screws on the side-panel silver cover of the device.
2. Place the wall-mount brackets on the silver cover and fasten the
screws as shown below. Use only the screws provided in the
wall-mounting kit package.
Connector Description
Power Connector
Connect the power jack (in the package) to the UC-8112-ME-T’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.
ARNING
Grounding the UC-8112-ME-T
Grounding and wire routing help limit the effects of noise due to
electromagnetic interference (EMI).

Serial Ports
The two serial ports (P1 and P2) use terminal connectors. Each port 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:
SD/SIM Card Sockets
The UC-8112-ME-T comes with an SD socket for storage expansion, and
a SIM card socket for cellular communication. The SD card/SIM card
sockets are located at the lower part on the front panel. T o install the
cards, remove the screw and the protection cover to access the sockets,
and then insert the SD card or the SIM card into the sockets direct ly. 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 con sole port is an RS-232 port that can be connected to with a 4-pin
pin header cable. You can use this port for debugging or firmware
upgrade. Note that the cable is not included in the package.
USB
The USB 2.0 port is located at the lower part of the front panel and
supports a USB storage device driver. By default, the USB storage is
mounted at
/mnt/usbstorage.
Real-time Clock
The real-time clock in the UC-8112-ME 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.
