Grounding UC-7400
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.

4. Installing UC-7400
Wall or Cabinet
The two metal brackets included with UC-7400 can be used to attach it to a
wall, or the inside of a cabinet. Using two screws per bracket, first attach the
brackets to the bottom of the UC-7400. Next, use two screws per bracket to
attach the UC-7400 to a wall or cabinet.
DIN-Rail Mounting
The aluminum DIN-Rail attachment plate is included in the package. To
attach the plate to UC-7400, situate the stiff metal spring towards the top.
STEP1: Insert the top of the
DIN-Rail into the slot just below the
stiff metal spring.
STEP2: The DIN-Rail attachment
unit will snap into place as shown
below.

NOTE: UC-7420 (shown in the figures) has a CF slot, PCMCIA slot, and two
USB 2.0 Host ports (circled below). UC-7410 does NOT have these three
features.

5. Connector Description
Power Connector
Connect the 12-48 VDC power line to UC-7400’s terminal block. If the
power is properly supplied, the Ready LED will show a solid green color
when the OS is ready.
SG: The Shielded Ground (sometimes called Protected
Ground) contact is the left most contact of the 3-pin
power terminal block connector when viewed from the
angle shown here. Connect the SG wire to an
appropriate grounded metal surface.
Ethernet Port
The two 10/100 Mbps Ethernet ports (LAN 1 and LAN 2) use RJ45
connectors.

PCMCIA
The PCMCIA slot supports the CardBus (Card-32) Card standard and 16-bit
(PCMCIA 2.1/JEIDA 4.2) Card standard. It 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 UC-7400 to a
Wireless LAN, with both 802.11b and 802.11g interfaces supported.
CompactFlash
UC-7420 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

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.
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.
LAN 1
LAN 2
Default IP Address
192.168.3.127
192.168.4.127
and then
#rpm –ivh /mnt/cdrom/mxscaleeb-3.3.2-1.386.rpm.
8. Configuring the Ethernet Interface
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.
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
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.

11. Compiling and Running Hello.c
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.

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
Once the UC-7400 is powered on, and the Ready LED will light up, and a
login page will open. Use the following default Login name and Password to
proceed.
