surface, such as a metal panel.
SG: The Shielded Ground (sometimes called
Protected Ground) contact is the right most
contact of the 3-pin power terminal block
connector, as viewed from the angle shown
here. Connect the SG wire to an appropriate
grounded metal surface.

SO-DIMM Socket for Memory Module
The ThinkCore V481 has an internal 200-pin SO-DIMM socket for
installing a DDR SDRAM memory module. The V481-XPE comes with
a 512 MB DDR SDRAM Module pre-installed. You may also replace the
module with your own (128 MB to 1 GB) DDR SDRAM memory
module. To replace the module, first remove the bottom cover of the
V481 to expose the SO-DIMM socket.
Compact Flash Socket
The ThinkCore V481-XPE comes with a built-in 1 GB industrial
CompactFlash card to store the WinXP Embedded operating system. A
second CompactFlash socket is located inside the V481. Installing a
second CompactFlash memory card will not affect the operating system.
Remove the bottom cover of the V481 to install the second CompactFlash
card.
USB Hosts
The ThinkCore V481 supports two USB 2.0 hosts. Both hosts are UHCI,
Rev. 2.0 compliant and support Plug & Play and also hot swapping. Both
hosts can be used to connect any USB device, such as a keyboard, mouse,
USB flash disk, or USB CD-ROM. In addition, both USB ports support
system boot up, which is activated by changing BIOS settings.
Audio Interface
The ThinkCore V481 has an audio interface that follows the AC97
standard and supports speaker output and audio line input.
Power On/Off Button
The power on/off button is located above the power input terminal block.
The button supports the ATX power on/off function. By default, the
button is set for “instant off.” You may also configure the button for
“delay 4 seconds” to guard against shutting down the power
unintentionally. In this case, you must press the power button
continuously for at least 4 seconds to shut off the power.
Reset Button
The reset button is designed to warm reboot the V481. Pressing the Reset
button initiates a hardware warm reboot. The button plays the same role
as a desktop PC’s reset button. After pressing the reset button, the system
will reboot automatically.
During normal use, you should NOT use the Reset Button. You should
only press the Reset Button if the software is not working properly. To
reset the system, work from the operating system environment by using
the corresponding software reboot function to protect the integrity of data
being transmitted or processed.
Real-time Clock
The embedded computer’s real-time clock is powered by a lithium battery.
We strongly recommend that you NOT replace the lithium battery
yourself. If the battery needs to be changed, please contact the MOXA
RMA service team.
ATTENTION
There is a risk of explosion if the battery is replaced by an incorrect type
of battery.
6. Powering on the V481
To power on the V481, connect the “terminal block to power jack
converter” to the V481’s DC terminal block (located on the left rear
panel), and then connect the power adaptor. Note that the Shielded
Ground wire should be connected to the right most pin of the terminal
block. It takes about 30 seconds for the system to boot up.
7. Starting the V481
Power on the V481 after connecting a monitor, keyboard, mouse, and
checking that the power source is ready. Once the operating system boots
up, the first step is to configure the Ethernet interface. The factory default
settings for the V481’s dual LANs are shown below. You can use a
cross-over Ethernet cable to connect directly from the PC to the V481 to
test if the LAN settings are correct.
Default IP Address Netmask
LAN 1
192.168.3.127 255.255.255.0
LAN 2 (Gigabit)
192.168.4.127 255.255.255.0
8. Configuring the Ethernet Interface
Follow these steps to configure the Ethernet interface:
Step 1: [My Device] Æ [Control panel] Æ [Network Connections] to
enter the network setting page.
Step 2: Right-Click the LAN interface (e.g., Local Area Connection 2) to
configure and click property. A configuration window will pop up
Step 3: After inputting the proper IP address and netmask, click OK.
