4. Installing UC-7420/7410

Wall or Cabinet Mounting

Use the included metal brackets to attach the unit to a wall or inside a cabinet. First, attach the brackets to the bottom of the UC-7420/7410 using two screws per bracket. Then, use two screws per bracket to secure the unit to the wall or cabinet.

DIN-Rail Mounting

The package includes an aluminum DIN-Rail attachment plate. To attach the plate to the UC-7420/7410, position the stiff metal spring towards the top.

Step 1: Insert the top of the DIN-Rail into the slot just below the stiff metal spring.

Step 2: The DIN-Rail attachment will snap into place.

To remove the UC-7420/7410 from the DIN-Rail, reverse Steps 1 and 2.

5. Connector Description

Power Connector

Connect the 12-48 VDC power line to the unit's terminal block. The Ready LED will show a solid green color when the OS is ready, indicating proper power supply.

Grounding

Grounding and wire routing help limit noise from electromagnetic interference (EMI). Run the ground connection from the ground screw to a grounded metal surface before connecting power. This product is intended for mounting to a well-grounded surface, such as a metal panel.

SG (Shielded Ground): The SG contact is the leftmost contact of the 3-pin power terminal block connector (when viewed from the front). 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.

Serial Port

The eight serial ports (P1 to P8) use RJ45 connectors. Each port can be software-configured as RS-232, RS-422, or RS-485. The pin assignments are:

PCMCIA

The PCMCIA slot supports CardBus (Card-32) and 16-bit (PCMCIA 2.1/JEIDA 4.2) standards. It supports +3.3V, +5V, and +12V at 120 mA. Wireless LAN card expansion is optional, with Moxa providing cards supporting 802.11b and 802.11g.

CompactFlash

UC-7420 provides one CompactFlash slot for type I/II card expansion. Moxa offers a CompactFlash disk for plug-and-play expansion. Other computer supply outlets also offer compatible flash disks. The CompactFlash will be mounted at /mnt/hda.

Device Features

Console Port

The console port is an RJ45 RS-232 port, connectable to V90 or GPRS modems via PPP. Pin definitions match the eight serial ports (P1 to P8).

Reset to Default Button

Press and hold the "Reset to Default" button for at least 5 seconds to load factory default configuration. The system will reboot automatically. The Ready LED blinks for 5 seconds then glows steadily when the system is ready.

Reset Button

Activates the hardware reset function. Use only if software malfunctions. For Linux systems, rebooting the OS is recommended to avoid data loss.

LCM & Keypad

The UC-7420/7410 Series features an LCM screen and five input buttons. The LCM displays 16 columns and 8 rows of text (ASCII 0x20-0x7F). Keypad button functions are application-defined. Refer to the Moxa Device API for programming information.

USB

The USB 2.0 Host port supports USB storage device drivers. The USB 1.1 Client port is reserved for future enhancements.

Real Time Clock

The real-time clock is powered by a lithium battery. Replacement should only be done by a qualified Moxa support engineer. Contact the Moxa RMA service team for battery replacement. ⚠️ Caution: There is a risk of explosion if the battery is replaced with an incorrect type.

6. Powering on UC-7420/7410

Connect the "terminal block to power jack converter" to the DC terminal block (rear panel) and then connect the power adaptor. Ensure the Shielded Ground wire is connected to the rightmost pin of the terminal block. Boot-up takes approximately 30 seconds. The Ready LED will light up when the system is ready, and network settings will appear on the LCM display.

7. Connecting UC-7420/7410 to a PC

Connection can be made via the serial console port or Telnet over the network.

Serial Console Port Settings: Baud rate=115200 bps, Parity=None, Data bits=8, Stop bits=1, Flow Control=None. Remember to select "VT100" terminal type. Use the CBL-RJ45F9-150 cable.

Telnet Connection: Requires knowledge of the UC-7420/7410's IP address and netmask. Default LAN settings:

• LAN 1: IP Address = 192.168.3.127, Netmask = 255.255.255.0
• LAN 2: IP Address = 192.168.4.127, Netmask = 255.255.255.0

For first-time configuration, a cross-over Ethernet cable directly connecting the PC to the UC-7420/7410 is recommended. After power-on, the Ready LED will light up, and a login page will appear. Default login: root, Password: root.

8. Configuring the Ethernet Interface

For first-time network configuration via the console cable, edit the interfaces file:

#ifdown -a
//Disable LAN1/LAN2 interface first, before reconfiguring LAN settings. LAN 1 = ixp0, LAN 2=ixp1//
#vi /etc/network/interfaces
//check the LAN interface first//

After modifying the LAN interface settings, activate them immediately:

#sync ; ifup -a

Note: Refer to the UC-7420/7410 User's Manual for WLAN interface and other configuration details.

9. Developing Your Application

The application development process involves the following steps:

1. Power on the target device and connect to PC Linux.
2. Install GNU cross-compiler on PC Linux.
3. Install Glibc on PC Linux.
4. Install GDB client on PC Linux (optional).
5. Set up cross-compiler and Glibc environment variables.
6. Develop end-user application: Code program & Compile.
7. If the program is not debugged, repeat step 6.
8. Download to target to run and test.

10. Installing the UC-7420/7410 Tool Chain

The PC must have a Linux Operating System installed (Redhat 7.3/8.0, or Linux Kernel 2.4.18 and compatible versions recommended). The Tool Chain requires approximately 400 MB of hard disk space. Install from the UC-7420/7410 CD using the following commands:

#mount /dev/cdrom /mnt/cdrom
#rpm -ivh /mnt/cdrom/mxscaleeb-3.3.2-1.386.rpm

The Tool Chain will be installed automatically.

11. Compiling and Running Hello.c

The Tool Chain path is: PATH=/usr/local/mxscaleb/bin:$PATH. The UC-7420/7410 CD includes example programs; Hello.c is used here.

On your PC, execute:

# cd /tmp/
# mkdir example
# cp -r /mnt/cdrom/example/* /tmp/example
# cd /tmp/example/Hello
#make

This compiles Hello.c. Run the generated executable to produce hello-release and hello-debug.

Note: Moxa also offers a Windows Tool Chain that simulates a Linux environment for developing applications on Windows. Refer to the UC-7420/7410 User's Manual for installation details.
