Wall Mounting (Optional)

Step 1

Use four screws to fasten the
wall-mounting brackets on the
left panel of the computer.

Step 2

Use another four screws to mount
the computer on a wall or a
cabinet.

The Shielded Ground (sometimes called
Protected Ground) contact is the top 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.

to a wall:

Connector Description

Power Connector

Connect the power jack (in the package) to the UC-8100A-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.

Grounding the UC-8100A-ME-T

Grounding and wire routing help limit the effects of noise due to
electromagnetic interference (EMI).

Ethernet Ports

The two 10/100 Mbps Ethernet ports (LAN 1 and LAN 2) use RJ45
connectors.

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:

There are three antenna connectors on
the front panel of the UC-8100A-ME-T.
W1 and W3 are for cellular modules, and
W2 is for the GPS module. All three
connectors are of SMA type.

The UC-8100A-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. To 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 directly. 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 with a 4-pin
pin header cable. You can use this port for debugging or firmware
upgrade.

USB Port

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.
