There are four push buttons on the DA-662A’s front panel. The
buttons are used to enter text onto the LCD screen. The buttons
are MENU, (up cursor), (down cursor), and SEL:
Scrolls up through a list of items shown on the LCD
Scrolls down through a list of items shown on the LCD
screen’s second line
Selects the option listed on the LCD screen
Real-time Clock
The DA-662A’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.
Powering on Your DA-662A Computer
To power on the DA-662A, connect the power line to the DA-662A’s
AC power connector (located on the right side of the rear panel),
and then turn on the power switch. It takes about 30 seconds for
the system to boot up. Once the system is ready, the Ready LED on
the front panel will light up, and the DA-662A will display the
model name and firmware version on the LCD screen.
Connecting to DA-662A from a PC
There are two ways to connect to the DA-662A from 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 bits = 1, Flow Control =
None.
When using Telnet, you need to know the DA-662A’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
DA-662A.
Once the DA-662A 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
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 interface
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 settings of the LAN interface have been modified,
use the following commands to activate the LAN settings
immediately:
# sync ; ifup –a
Developing Your Application
Installing the DA-662A Tool Chain
The PC must have the Linux operating system pre-installed to
install the DA-662A GNU Tool Chain. Redhat 7.3/8.0/9.0 Fedora
Core 1/2/3/4/5 Debian 7 and later compatible versions are
recommended. The Tool Chain will use about 1 GB of your PC’s
hard disk space. Use the following command to install the Tool
Chain from the DA-662A Series CD:
# mount /dev/cdrom /mnt/cdrom
# sh /mnt/cdrom/Toolchain/
arm-linux_x.x.x-Vx_Build_YYMMDDHH.sh
The Tool Chain will be installed on your PC automatically.
Compiling and Running Hello.c
The path to the Tool Chain is:
#export PATH=“/usr/local/arm-linux-4.4.2-v4/bin:$PATH”
The DA-662A software 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.
