WARNING
This is a Class A product. In a domestic environment this product may cause radio interference, in which case the user may be required to take adequate measures.
Warning for European Users – Electromagnetic Compatibility
European Union Directive 89/336/EEC requires that this apparatus comply with relevant ITE EMC standards.
EMC compliance demands that this apparatus is installed within a VME enclosure designed to contain electromagnetic radiation and which will provide protection for the apparatus with regard to electromagnetic immunity. This enclosure must be fully shielded.
The connection of non-shielded equipment interface cables to this equipment will invalidate European Free
Trade Area (EFTA) EMC compliance and may result in electromagnetic interference and/or susceptibility levels that are in violation of regulations which apply to the legal operation of this device. It is the responsibility of the system integrator and/or user to apply the following directions, as well as those in the user manual, which relate to installation and configuration:
All interface cables should be shielded, both inside and outside of the enclosure. Braid/foil type shields are recommended for serial, parallel and SCSI interface cables. Where as external mouse cables are not generally shielded, an internal mouse interface cable must either be shielded or looped (1 turn) through a ferrite bead at the enclosure point of exit (bulkhead connector). External cable connectors must be metal with metal backshells and provide 360-degree protection about the interface wires. The cable shield must be terminated directly to the metal connector shell; shield ground drain wires alone are not adequate. Panel mount connectors that provide interface to external cables (e.g., RS232, USB, keyboard, mouse, etc.) must have metal housings and provide direct connection to the metal chassis. Connector ground drain wires are not adequate.
Environmental Protection Statement
This product has been manufactured to satisfy environmental protection requirements where possible. Many of the components used (structural parts, printed circuit boards, connectors, batteries, etc.) are capable of being recycled.
Final disposition of this product after its service life must be accomplished in accordance with applicable country, state, or local laws or regulations.

ACEX4405-LF
Chapter 1 – Introduction
ACEX4405-LF is a COM Express carrier board that supports both Type II and Type
III COM Express modules. This board has a small footprint of 95mm x 125mm.
The design includes Gigabit Ethernet ports, RS232/422 ports, and USB ports.
Module Features
Mini PCIe site which can accommodate either a full or half length module
Compact flash site with ejector
Dual Gigabit Ethernet (if supported by COM Express module)
Optional fan power interface
Standard ATX Power connector
LVDS for LCD panel display
LCD backlight control
Power, status, and user-defined LEDs
All interfaces use locking and latching connectors
Handling
Modules should be handled in ESD-safe work areas in order to prevent damage to sensitive components from electrostatic discharges. These areas must be designed and maintained to prevent ESD damage.
ESD Safe Work Area Guidelines
1. Module should be handled at properly designated work areas only.
2. Designated ESD safe work areas must be checked periodically to ensure their continued safety from ESD. The areas should be monitored for the following: a. Proper grounding methods. b. Static dissipation of work surfaces. c. Static dissipation of floor surfaces. d. Operation of ion blowers and ion air guns.
3. Designated work areas must be kept free of static generating materials such as styrofoam, vinyl, plastic, fabrics or any other static generating materials.
4. Work areas must be kept clean and neat in order to prevent contamination of the work area.
5. Modules should be handled by the edges. Avoid touching the component leads.
NOTE: When not installed in a system, modules must be enclosed in shielded bags or
boxes. There are three types of ESD protective enclosure materials this module was shipped in an approved ESD bag.
6. Whenever handling the module the operator must be properly grounded by one of the following: a. Wearing a wrist strap connected to earth ground. b. Wearing heel grounders and have both feet on a static dissipative floor surface.
7. Stacking of modules should be avoided to prevent physical damage.

Environmental Specifications
Flammability
The circuit board is made by an UL recognized manufacturer and has a flammability rating of UL94V-0.
Electrical Specifications
Power Supply Requirements
The ACEX4405 requires +3.3V and +5V for full operation, sinking 1705mW and
4117mW respectively. Per the COM Express specification, the COM module requires +12V for operation while +5V_Standby is optional.
LVDS Backlight Overview
From COM Express Carrier Design Guide Revision 1.0:
“Backlight inverters are either: voltage, PWM, or resistor controlled. The COM
Express specification provides two methods for controlling the brightness. One method is to use the backlight control and enable signals from the CPU chipset.
These signals are brought on COM Express LVDS_BKLT_EN and VDS_BKLT_CTRL.
LVDS_BKLT_CTRL is a Pulse Width Modulated (PWM) output that can be connected to display inverters that accept a PWM input. The second method it to use the LVDS I2C bus to control an I2C DAC. The output of the DAC can be used to support voltage controlled inverters. The DAC can be used driving the backlight
voltage control input pin of the inverter.”
Battery and Fan Selection
There are three conditions that need to be met when selecting a compatible fan:
1. Operates with +5V or +12V power
2. Connector is 3-pin, 2 mm pitch socket
3. Fan outputs tachometer signal
Panasonic, NMB, and Comair Rotron currently offer a tachometer output option on their fans.
The battery holder accommodates a CR1225 coin-cell battery.
Architecture
COM Module Considerations
The ACEX4405-LF is COM Express Type II compliant. In order for the ACEX4405-LF to fully operate, the attached COM Express module must be configured such that the lowest two PCIe lanes are PCIe x1 pipes.
Pushbuttons
When viewing the non-COM connector side of the board, you will notice two momentary switches.

SW2400
The SW2400 pushbutton will power down the system, and then power up a system utilizing a standard ATX power supply.
Note
Depending on your default BIOS settings, the power button may need to be pressed in order to power up your system.
