Console Port

The console port is an RJ45 RS-232 port. It is designed for 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 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.

LCM & Keypad

UC-7400 Series has an LCM screen and five input buttons on the top panel.

Refer to the Moxa Device API for programming information.

The LCM can display 16 columns and 8 rows of text with ASCII code

starting from 0x20 to 0x7F. The function of the five keypad buttons can be

defined by your application.

USB

The USB 2.0 Host port now supports a USB storage device driver. The

USB 1.1 Client port is reserved for future enhancement.

Real Time Clock

UC-7400’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 UC-7400

To power on UC-7400, connect the “terminal block to power jack converter”

to the UC-7400's DC terminal block (located on the left back 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, and UC-7400’s network settings will appear on the LCM

display.

7. Connecting UC-7400 to a PC

There are two ways to connect UC-7400 to a PC, through the serial console

port or by Telnet over the network. The COM settings for the serial console

port are: Baud rate=115200 bps, Parity=None, Data bits=8, Stop bits =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 UC-7400’s serial console

port.

To use Telnet you will need to know UC-7400’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-7400.

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-7400 is powered on, and the Ready LED will light up, and a

proceed.

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 = ixp0, LAN 2= ixp1//

#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-7400 User’s Manual for information on how to

configure the WLAN interface, and other configuration information..

9. Developing Your Application

10. Installing the UC-7400 Tool Chain

The PC must have the Linux Operating System pre-installed to install the

UC-7400 GNU Tool Chain. Redhat 7.3/8.0, or Linux Kernel 2.4.18 and

compatible versions are recommended. The Tool Chain will use about 400

MB of your PC’s hard disk space. Use the following command to install the

Tool Chain from the UC-7400 CD

#mount /dev/cdrom /mnt/cdrom

and then

#rpm –ivh /mnt/cdrom/mxscaleeb-3.3.2-1.386.rpm.

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/mxscaleb/bin:$PATH

The UC-7400 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.

NOTE: Moxa also provides the Windows Tool Chain for UC-7400. The

Windows Tool Chain simulates a Linux environment on a Windows operating

system, allowing you to develop programs for UC-7400 on a Windows

platform. The UC-7400 User’s Manual contains complete details on how to

install the Windows Tool Chain.
