Using WPA_SUPPLICANT to Support WPA and WPA2
This embedded computer supports the WPA and WPA2 functions using the /bin/wpa_supplicant
program. We wrote a shell script to help you use this function:
Step 1:
Edit the
ssid and psk variables in the file etc/wpa_supplicant.conf.
network={
ssid=”12345678901”
key_mgmt=WPA-PSK
proto=WPA RSN
pairwise=TKIP CCMP
group=TKIP CCMP
psk=”0987654321234”
}
Step 2:
Type
/etc/init.d/wpa.sh eth1 start to enable this function. To stop the function, type
/etc/init.d/wpa.sh eth1 stop
SD Slot and USB for Storage Expansion
The W341 and W321 provide an SD slot for storage expansion. MOXA provides an SD flash disk
for plug & play expansion that allows users to plug in a Secure Digital (SD) memory card
compliant with the SD standard V1.0 for up to 1 GB of additional memory space. The following
steps show you how to install SD card into the W341 and W321.
W321
The SD slot is located on the right side of the W321 enclosure. To install an SD card, you must
first remove the SD slot’s protective cover to access the slot, and then plug the SD card directly
into the slot.
The SD card will be mounted at /mnt/sd. Detailed installation instructions are shown below:
Step 1: Use a screwdriver to remove the screws holding the SD slot’s outer cover.
Step 2: After removing the cover, insert the SD memory card as shown.
