1 Chapter 1 Introduction Microsoft® Windows® CE 5.0 is an open, scalable, 32-bit operating system (OS) that allows you to build a wide range of innovative, small footprint devices. A typical Windows® CE-based device is designed for a specific use, and often runs disconnected from other computers, or distributed as a front-end to a centralized host.
DA-660-8/16-CE User’s Manual Introduction Overview The DA-660 WinCE embedded computer is ideal for reliable, small-footprint, programmable, communication-centric applications. DA-660 uses an Intel XScale IXP-422 RISC-based CPU running at a clock rate of 266 MHz. Unlike the CISC architecture under an X86 CPU, the RISC design supports compact instruction sets. A RISC-based CPU generates less heat and consequently enhances reliability.

DA-660-8/16-CE User’s Manual Introduction In addition, the FAT file system searches for free space sequentially when performing write operations. As files are deleted, free storage space becomes more and more fragmented, making it difficult to search. When a file is frequently updated, data is deleted and rewritten to the same memory blocks over and over again. Eventually, the FAT file system would be unable to read those blocks, causing the operating system to hang.
2 Chapter 2 Getting Started In this chapter, we explain how to use a PC to operate a DA-660 computer. For clarity, the PC is referred to as a development workstation and the DA-660 computer is called a target computer. In addition, manual steps are described to facilitate operations such as system time adjustment, troubleshooting network connectivity, etc.
DA-660-8/16-CE User’s Manual Getting Started Starting Your DA-660 Computer Connect the power cord that is shipped with the package to the AC/DC power connector (located on the right side of the rear panel) of the target computer. It takes about 30 to 60 seconds for the system to boot up. Once the system is ready, the Ready LED lights up and glows steadily till the computer is shutdown and the computer displays its model name and firmware version on the LCM.

Execute the following command. \> netconfig –n LAN1 –i 192.168.1.5 –m 255.255.255.0 –g 192.168.1.254 –d 192.168.2.6 Use command netconfig to view the new settings.
DA-660-8/16-CE User’s Manual Getting Started User/Group Management User Group: You often want the target computer to be accessible by multiple users with different needs. For example, a specific service, such as ftp or telnet, is accessible only by the users within the permissible group. By default, three user groups, namely ftpd, telnetd, and administrators are pre-created for your convenience. Adding a Group: Use the command useradd –g to create a user group.
DA-660-8/16-CE User’s Manual Getting Started Adjusting System Time and RTC Time The DA-660 computer has two time settings, the system time (or CPU clock) and the RTC (Real Time Clock) time. The system time regulates the execution of instructions and the RTC keeps track of the time even when the computer is turned off. RTC time runs on a special battery that is not connected to the normal power supply. Do not confuse a computer's real-time clock with its CPU clock.

SNMP was developed to monitor and manage networks.
3 Chapter 3 Web-based Management System Note: Internet Explorer 5.5 or above is required to use the web based management system. DA-660 ready-to-run embedded computers are network-centric platforms designed to be used as front-end computers for data acquisition and industrial control. Due to the distributed characteristics of the devices that these computers control, they often reside in harsh areas as the devices themselves and are away from system administrators.
DA-660-8/16-CE User’s Manual Web-based Management System Logging Onto Web-based Management System A web-based management system is provided for the DA-660-CE for easier management and system administration. The web-based management system uses a menu bar and CGI pages to provide access to commonly-used features. Before using the web-based management system, your PC must have a web browser installed and a network connection to the DA-660-CE. To open the web-based management system, follow these steps: 1.
