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.
Grounding the UC-8112-ME-T
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
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.
Ethernet Ports
The two 10/100 Mbps Ethernet ports (LAN 1 and LAN 2) use RJ45
connectors.
