4. Installing the W341
Wall or Cabinet Mounting
The W341 comes with two metal attachment plates for attaching the
embedded computer to a wall or the inside of a cabinet. First, use two
screws per bracket to attach the brackets to the rear of the W341. Next,
use two screws per bracket to attach the W341 to a wall or cabinet.
The heads of the screws should be less than 6.0 mm in
diameter, and the shafts should be less than 3.5 mm in
diameter, as shown by the figure at the right.

DIN-Rail Mounting
DIN-rail attachments can be purchased separately to attach the product
to a DIN-rail. When snapping the attachments to the DIN-rail, make
sure that the stiff metal springs are at the top.

5. Connector Description
Power Connector
Connect the 12 to 48 VDC LPS or Class 2 power line to the W341’s
terminal block. If the power is properly supplied, the Power LED will
light up. The OS is ready when the Ready LED glows a solid green.
Grounding the W341
Grounding and wire routing help limit the effects of noise due to
electromagnetic interference (EMI). Run the ground connection from
the ground screw to the grounding surface prior to connecting the
power.

SD Interface
The W341 has an internal SD slot for storage expansion. The SD slot
allows users to plug in a Secure Digital (SD) memory card compliant
with the SD 1.0 standard for up to 1 GB of additional memory space, or
a Secure Digital High Capacity (SDHC) memory card compliant with
the SD 2.0 standard for up to 16 GB of additional memory space. To
install an SD card, first use a screw driver to remove the SD slot cover
to access the slot. The slot is located on the top panel next to the
antenna. Plug the SD card directly into the socket, and then replace the
SD slot cover. The SD card will be mounted at /mnt/sd. To remove
the SD card from the slot, press the SD card in slightly with your finger,
and then remove your finger to cause the card to spring out partially.
You may now grasp the top of the card with two fingers and pull it out.
Console Port
The serial console port is a 4-pin pin-header RS-232 port. It is designed
for serial console terminals, which are useful for viewing boot-up
messages. Use the CBL-4PINDB9F-100 cable included with the
product to connect a PC to the W341’s serial console port.
Reset
Press the Reset button continuously for at least 5 seconds to load the
factory default configuration. After the factory default configuration
has been loaded, the system will reboot automatically. The Ready LED
will blink on and off for the first 5 seconds, and then maintain a steady
glow once the system has rebooted.
USB
The USB 2.0 Host port now supports a USB storage device driver. The
USB storage will be mounted at /mnt/usbstorage.
Real-time Clock
The W341’s real-time clock is powered by a lithium battery. We
strongly recommend that you do not replace the lithium battery without
help from a qualified 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 by an incorrect type
of battery.
6. Powering on the W341
To power on the W341, connect the “terminal block to power jack
converter” to the W341’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. Once the
system is ready, the Ready LED will light up.
Power Consumption
y600 mA @ 12 VDC with no USB devices sttached
y1.2A @ 12 VDC with USB devices on each port at max spec 500 mA
@ 5 VDC
7. Connecting the W341 to a PC
There are two ways to connect the W341 to a PC: (1) through the serial
console port, or (2) by Telnet over the network. The COM settings for
the serial console port are: Baudrate = 115200 bps, Parity = None,
Data bits = 8, Stop bits = 1, Flow Control = None.
ATTENTION
Use the CBL-4PINDB9F-100 cable included with the product to connect
a PC to the W311/321’s serial console port. Remember to choose VT100
terminal type.
To use Telnet, you will need to know the W341’s IP address and
netmask. The default LAN settings are shown below. For first-time
configuration, you may find it convenient to use a cross-over Ethernet
cable to connect directly from the PC to the W341.
Default IPAddress Netmask
LAN 1 192.168.3.127 255.255.255.0
LAN 2 (wireless) 192.168.4.127 255.255.255.0
Once the W341 is powered on, the Ready LED will light up, and a
login page will open. Use the following default Login name and
Password to proceed. The defaults are:
Login: root
Password: root
8. Configuring the Ethernet Interface
If you use the console cable for first-time configuration of the network
settings, use the following commands to edit the interfaces file:
# ifdown –a
//Disable LAN1 interface first, before you reconfigure
The LAN settings. LAN 1 = eth0//
# vi /etc/network/interfaces
//check the LAN interface first//
After the boot setting of the LAN interface has been modified, use the
following commands to activate the LAN settings immediately:
# sync ; ifup –a
NOTE: Refer to the W341 User’s Manual for information on how to
configure the WLAN interface, and for other configuration
information.
