User’s Manual

1 Introduction

1.1 Overview

The Matrix MXC-4000 series is a fanless, embedded computer based on the next generation Intel® Atom™ D510 dual-core pro­cessor to offer greater computing power for your applications. The MXC-4000 inherits its exceptional fanless and cable-less design from existing Matrix C series, with the addition of innovative fea­tures, such as an eSATA interface, an LVDS output, and a hot­pluggable fan option.
The MXC-4000 series features an Intel® Atom™ D510 dual­core1.6 GHz processor to boostits performance to almost twice that of the Atom™ N270 platform, while maintaining the same overall power consumption. Its PCI and PCIe slots give you the possibility to integrate off-the-shelf PCI/PCIe cards and develop a configurable application platform. Built-in isolated DIO channels are provided for general industrial control. Its LVDS output on the front panel allows you to directly connect to a LCD panel. The MXC-4000 series also provides two eSATA ports to enable the capability of either expanding storage capacity or using hot-swap­pable SATA drives.
Introduction 1
Matrix MXC-4000 Series User’s Manual
Leveraging a reliable fanless and durable cable-less design, the MXC-4000 series exhibits excellent dependability in harsh envi­ronments, where severe temperature variation and vibration may exist.
The MXC-4000 series provides an optional hot-pluggable fan module to dissipate heat generated within the system when high power consumption PCI/PCIe cards are installed. This ingenious mechanical design retains a cable-less structure which dramati­cally improves thermal stability when PCI/PCIe cards installed. Combining a reliable design with more computing power and inno­vative features, the Matrix MXC-4000 series is the optimal choice to base your rugged application system on.

2.3 Operating Principles

2.3.1 Isolated Digital Input

Isolated digital input utilizes an open collector transistor structure, with input voltage range of 0 V to 24 V and input resistance of 2.4K . Connection between external signals and the MXC-4002D/ 4011D controller is as shown.
Note: The common input junction can be common ground or
common power, based on the applied environment, such that digital input can be either a current source or current sink.
Figure 2-1: Isolated Input Connection
System Description 15
Matrix MXC-4000 Series User’s Manual

2.3.2 Isolated digital Output

Common ground connection of isolated digital output and common power connection of isolated digital output are shown.
When isolated digital output enters an “ON” state, sink current is conducted through the transistors. When an “OFF” state is entered, there is no current through the transistors.
Note: When the load is of an “inductance nature” such as a
relay, coil or motor, the VDD pin must be connected to an external power source, with the extra connection utilized for the ‘fly-wheel diode’ to form a current-release closed loop, by which the transistors are protected from high reverse voltage generated by the inductance load when the output is switched from “ON” to “OFF”.

4 BIOS Settings and Driver Installation

4.1 BIOS Setting

The Basic Input/Output System (BIOS) is a program that provides a basic level of communication between the processor and periph­erals. In addition, the BIOS also contains codes for various advanced features applied to the MXC-4000 series controller. The BIOS setup program includes menus for configuring settings and enabling features of MXC-4000 series. Most users do not need to use the BIOS setup program, as the MXC-4000 series controller ships with default settings that work well for most configurations.
In this section, BIOS options are illistrated.
Warning: Changing BIOS settings may lead to incorrect
controller behavior and possibly an unbootable controller. If this happens, follow the instructions in Section 2.4.4 to clear CMOS and then restore the default settings. In general, do not change a BIOS setting unless you are absolutely certain of what it does.

A WDT (watchdog timer) is a hardware mechanism to reset the system when the operating system or application is halted. A typi­cal usage of WDT is to start the timers and periodically reset the timer, and when timer is expired, the system resets. You need to install the WDT driver to program the WDT.
Please follow the following steps to install WDT driver for theMXC­4000 series
1. Close any running application.
2. Insert the ADLINK All-in-One DVD. The WDT driver is located in the directory: x:\Driver Installation\Matrix\MXC-4000\WDT\ where x: denotes the DVD-ROM drive.
3. Execute setup.exe and follow on-screen instructions to complete the setup.
4. After installation completes, reboot your system.

A.1 Watchdog Timer (WDT) Function Reference

This appendix describes the usage of the watchdog timer (WDT) function library for the MXC-4000 controller. The watchdog timer is a hardware mechanism to reset the system in case the operating system or an application halts. After starting watchdog timer, you need to periodically reset the watchdog timer in the application before the timer expires. Once watchdog timer expires, a hard­ware-generated signal is sent to reset the system.
To use the WDT function library with the MXC-4000 series, you need to include the header file WDT.h and linkage library WDT.lib in your C++ project.

InitWDT
@ Description
Initialize the watchdog timer function of MXC-4000 series con­troller. InitWDT must be called before the invocation of any other WDT function.
@ Supported controllers
MXC-4000 series
@ Syntax
C/C++
BOOL InitWDT()
@ Parameters
None
@ Return code
TRUE if watchdog timer is successfully initialized.
FALSE if watchdog timer is failed to initialize.

SetWDT
@ Description
Set the timeout value of watchdog timer. There are two param­eters for this function to indicate the timeout ticks and unit. Users should call ResetWDT or StopWDT before the expiration of watchdog timer, or the system will be reset.
@ Supported controllers
MXC-4000 series
@ Syntax
C/C++
BOOL SetWDT(BYTE tick, BYTE unit)
@ Parameters
tick
Specify the number of tick for watchdog timer. A valid value is 1 - 255.
unit
Specify the timeout ticks of the watchdog timer.
Value Description
The unit of tick is second. For example, when you specify tick
0
as 100 and unit as 0, the timeout value is 100 seconds.
The unit of tick is minute. For example, when you specify tick
1
as 100 and unit as 1, the timeout value is 100 minutes.
@ Return codes
TRUE if timeout value of watchdog timer is successfully set.
FALSE if timeout value of watchdog timer is failed to set.

StartWDT
@ Description
Start the watchdog timer function. Once the StartWDT is invoked, the countdown of watchdog timer starts. Users should call ResetWDT or StopWDT before the expiration of watchdog timer, or the system will be reset.
@ Supported controllers
MXC-4000 series
@ Syntax
C/C++
BOOL StartWDT()
@ Parameters
None
@ Return codes
TRUE if watchdog timer is successfully started.
FALSE if watchdog timer is failed to start.

ResetWDT
@ Description
Reset the watchdog timer. The invocation of ResetWDT allows users to restore the watchdog timer to the initial timeout value specified in SetWDT function. Users should call ResetWDT or StopWDT before the expiration of watchdog timer, or the sys­tem will be reset.
@ Supported controllers
MXC-4000 series
@ Syntax
C/C++
BOOL ResetWDT()
@ Parameters
None
@ Return codes
TRUE if watchdog timer is successfully reset.
FALSE if watchdog timer is failed to reset.
Appendix 69

StopWDT
@ Description
Stop the watchdog timer.
@ Supported controllers
MXC-4000 series
@ Syntax
C/C++
BOOL StopWDT()
@ Parameters
None
@ Return codes
TRUE if watchdog timer is successfully stopped.
FALSE if watchdog timer is failed to stop.
