□ Package Checklist
□ Product Features
□ Product Hardware Specifications

Overview

The UC-8410/8416/8418/8430 features 8 RS-232/422/485 serial ports, 3 10/100 Mbps Ethernet ports, 4 digital input channels and 4 digital output channels (12 digital input channels and 12 digital output channels for the UC-8418), 8 10/100 Mbps switch ports (UC-8416 only), a CompactFlash slot for flash disk expansion, and 2 USB ports (6 USB ports for UC-8430) for adding additional memory (such as a USB flash drive).

The UC-8410/8416/8418/8430 uses an Intel XScale IXP435 533 MHz RISC CPU. Unlike the X86 CPU, which uses a CISC design, the IXP435's RISC design architecture and modern semiconductor technology provide the UC-8410/8416/8418/8430 with a powerful computing engine and communication functions, but without generating a lot of heat. The built-in 16 MB (32 MB for UC-8430) NOR Flash ROM and 256 MB SDRAM give you enough memory to run your application software directly on the UC-8410/8416/8418/8430. Since the dual LAN ports are built into the IXP435 CPU, the UC-8410/8416/8418/8430 is good solution for network security applications.

LED Indicators

The UC-8410/8416/8418/8430 has 14 LED indicators on the top panel. Refer to the following table for information about each LED.

LED Name Color Meaning
Power	Green	Power is on.
	Off No power input or any other power error.
Ready	Green	System is ready.
	Off OS boot up failure or other system initialization error.
Storage	Yellow (not blinking)	CF card inserted.
	Yellow (blinking)	Data is being read or written.
	Off No CF card inserted.
Battery	Red (blinking)	Battery is recharging.
	Off Battery is normal.
TX 1-8	Green	Data is being sent through the serial port.
	Off Data is not being transmitted.
RX 1-8	Yellow	Data is being received through the serial port.
	Off Data is not being received.

Reset Button

The button labeled Reset returns the UC-8410/8416/8418/8430 to its factory default configuration.

Press the Reset 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.

We recommend that you only use this function if the software is not working properly and you want to load factory default settings. To reset an embedded system, always use the software reboot command / > reboot to protect the integrity of data being transmitted or processed.

ATTENTION

Reset button preserves user's data

The Reset button will NOT format the user directory and erase the user's data. Pressing the Reset button continuously for at least 5 seconds will only load the configuration file. For the Linux OS, all files in the /etc, /home and /tmp directories will revert to their factory defaults, but other user data will still exist in the Flash ROM. For the Windows CE 6.0 OS, all configuration in registries will revert to their factory defaults.

Real Time Clock

The UC-8410/8416/8418/8430'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.

WARNING

There is a risk of explosion if the battery is replaced by an incorrect type.

Be careful when handling the UC-8410/8416/8418/8430. When plugged in, the UC-8410/8416/8418/8430's internal components generate heat, and the outer casing may feel hot to the touch.

You should also observe the following common wiring rules:

• Use separate paths to route wiring for power and devices. If power wiring and device wiring paths must cross, make sure the wires are perpendicular at the intersection point.
  NOTE: Do not run signal or communication wiring and power wiring in the same wire conduit. To avoid interference, wires with different signal characteristics should be routed separately.
• You can use the type of signal transmitted through a wire to determine which wires should be kept separate. The rule of thumb is that wiring that shares similar electrical characteristics can be bundled together.
• Keep input wiring and output wiring separate.
  • Where necessary, we strongly recommend that you label wiring to all devices in the system.

Connecting the Power

The UC-8410/8416/8418/8430 has a 3-pin terminal block for a 12 to 48 VDC power input.

The following figures show how the power input interface connects to external power source. If the power is properly supplied, t the Ready LED will illuminate with a solid green color after 30 to 60 seconds have passed.

ATTENTION

The power for this product is intended to be supplied by a Listed Power Supply Unit that is rated to deliver 12 to 48 VDC at a minimum of 1280 mA for 12 VDC, and 300 mA for 48 VDC.

Grounding the UC-8410/8416/8418/8430

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 devices.

ATTENTION

This product is intended to be mounted to a well-grounded mounting surface, such as a metal panel.

SG: The Shielded Ground (sometimes called Protected Ground) contact is the right 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.

ATTENTION

A shielded-type power cord is required in order to meet FCC emission limits and also to prevent interference to nearby radio and television reception. It is essential that only the supplied power cord be used.

You are cautioned that changes or modifications not expressly approved by the party responsible for compliance could void your authority to operate the equipment.
