PCMCIA
The PCMCIA slot supports the CardBus (Card-32) card standard and 16-bit
(PCMCIA 2.1/JEIDA 4.2) card standard. The slot supports +3.3V, +5V, and
+12V at a working voltage of 120 mA. Wireless LAN card expansion is
optional. The Wireless LAN card provided by Moxa lets you connect the
UC-7408-LX Plus to a Wireless LAN, with both 802.11b and 802.11g
interfaces supported.
CompactFlash
The UC-7408-LX Plus provides one CompactFlash slot that supports
CompactFlash type I/II card expansion. Currently, Moxa provides a
CompactFlash disk for plug & play expansion. You may also use flash disks
available from most computer supply outlets. The CompactFlash will be
mounted at /mnt/hda
Console Port
The console port is an RJ45 RS-232 port. It is designed for use as a serial
console, and can be connected to a V90 or GPRS modem via PPP. The pin
definitions are the same as for the eight serial ports (P1 to P8).
Reset to default Button
Press the “Reset to Default” 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.
Reset Button
Press the “Reset” button to activate the hardware reset function. You should
only use this function if the software does not function properly. To reset a
Linux system, you should reboot the operating system to avoid deleting
important data.
USB
The USB 2.0 Host port now supports a USB storage driver.
Real Time Clock
The UC-7408-LX Plus’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.
6. Powering on the UC-7408-LX Plus
To power on the UC-7408-LX Plus, connect the “terminal block to power
jack converter” to the UC-7408-LX Plus’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.
7. Connecting the UC-7408-LX Plus to a PC
There are two ways to connect the UC-7408-LX Plus to a PC, through the
serial console port or by Telnet over the network. The COM settings for the
serial console port are: Baudrate=115200 bps, Parity=None, Data bits=8,
Stop bit(s) =1, Flow Control=None.
ATTENTION
Remember to choose the “VT100” terminal type. Use the CBL-RJ45F9-150
cable included with the product to connect a PC to the UC-7408-LX Plus’s
serial console port.
To use Telnet you will need to know the UC-7408-LX Plus’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 UC-7408-LX Plus.
Default IP Address Netmask
LAN 1 192.168.3.127 255.255.255.0
LAN 2 192.168.4.127 255.255.255.0
Once the UC-7408-LX Plus 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.
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/LAN2 interface first, before you
reconfigure the LAN settings. LAN 1 = eth0, LAN 2= eth1//
#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 UC-7408-LX Plus User’s Manual for information on
how to configure the WLAN interface, and other configuration information.

10. Installing the UC-7408-LX Plus Tool Chain
The PC must have the Linux Operating System pre-installed to install the
UC-7408-LX Plus GNU Tool Chain. Fedora 5, or Linux Kernel 2.6.10 and
compatible versions are recommended. The Tool Chain will use about 400
MB of your PC’s hard disk space. Use the following commands to install the
Tool Chain from the UC-7408-LX Plus CD:
#mount /dev/cdrom /mnt/cdrom
#/mnt/cdrom/tool-chain/Linux/xscale_be-x.x.sh
The Tool Chain will be installed on your PC automatically.
11. Compiling and Running Hello.c
The path to the Tool Chain is:
PATH=/usr/local/xscale_be/bin:$PATH
The UC-7408-LX Plus CD also includes several example programs. Here we
use Hello.c as an example to show you how to compile and run your
applications. Type the following commands on your PC:
# cd /tmp/
# mkdir example
# cp –r /mnt/cdrom/example/* /tmp/example
Next, go to the Hello subdirectory and type the following command:
#make
to finish compiling Hello.c.
Finally, run the executable file that was created to generate hello-release and
hello-debug.
