Moxa IA262-I-CE [10/74] Supporting servers and daemons
IA261/262 WinCE User’s Manual Introduction
y Network Utilities (IpConfig, Ping, Route) - Utilities for troubleshooting various network
problems.
y TCP/IP - Includes IP, Address Resolution (ARP), Internet Control Message (ICMP), Internet
Group Membership (IGMP), Transmission Control (TCP), User Datagram (UDP), name
resolution and registration, and DHCP.
Supporting Servers and Daemons
In addition to the development and communication capability, IA26X-CE embeds the services and
daemons as stated next. These common and easy-to-use application servers help users to migrate
the IA26X-CE embedded computer to the industrial communication application very easily and
conveniently.
y Telnet Server - A sample server that allows remote administration through a standard telnet
client.
y FTP Server - A sample server used for transferring files to and from remote computer
systems over a network using TCP/IP.
y File Server - The File Server functionality in Microsoft® Windows® CE enables clients to
access files and other resources over the network.
y Web Server (HTTPD) - Includes ASP, ISAPI Secure Socket Layer support, SSL 2, SSL 3,
and Transport Layer Security (TLS/SSL 3.1) public key-based protocols, and Web
Administration ISAPI Extensions.
y Dial-up Networking - Consists of RAS client API and the Point to Point Protocol (PPP).
RAS and PPP support Extensible Authentication Protocol (EAP) and RAS scripting.
y Watchdog Service – It’s a CPU Hardware function for reset CPU in a user specified time
interval. You must call the Moxa library function to trigger it.
Learning Firmware Build Versions
There are two ways to obtain the firmware version of the IA26X-CE computer. This information is
particularly important for the purpose of feature identification.
y Examine the welcome message after you logon the computer.
y Logon the Web-based management system (described in a later chapter) to view the system
information.
Memory and File Systems
From the 128M bytes of SDRAM space, the main memory has a capacity of about 112M bytes in
which the operating system and user applications run. The kernel image occupies the rest of the
space.
The internal file system in the IA26X-CE computer controls access to ROM and also provides file
storage in the object store, which is in the RAM. The ROM file system provides persistent storage
for applications and their related data even when the main power supply is lost. It integrates the
read-only files that are stored in Flash ROM with the read/write files of both an application and a
user. In the IA26X-CE computer, a child directory named “NORFlash” under the root indicates the
ROM storage of the flash memory of size 12M bytes.
The root directory is a RAM file system of size 12M bytes. It can be used for storing temporary
files for your applications. However, do not place persistent files or applications in the root
directory because they will be wiped out when the system is shutdown. Instead, place them under
the directory “NORFlash”.
