Software Specifications

Applications Development Environment

To make EM-2260 an easy-to-use programming environment, its Windows CE 6.0 environment provides the following common, popular application development features that make programming convenient and easy as in a PC environment.

• C Libraries and Run-times - Compared to the C libraries and run-times used on a desktop PC running Windows, the C libraries and run-times on a EM-2260 is a subset of the WIN32 APIs. It supports full ANSI C run time, standard input/output library, standard input/output ASCII library and standard ASCII string functions. In addition, it supports compiler C++ exception handling equivalent and Run-Time Type Information (RTTI) equivalent to the desktop C++ compilers.
• Component Services (COM and DCOM) - The Common Object Model (COM) is an operating system-independent, object-oriented system for creating binary software components that can interact with other COM-based components in the same process space, in other processes, or on remote machines.
• SOAP Toolkit - SOAP is an XML - based protocol for object exchange and remote procedure calls. Microsoft Windows CE 6.0 provides functionality similar to the SOAP Toolkit version 2 on the desktop. It provides a layer that allows COM objects to use SOAP as the transport protocol for remote procedure calls and to interact with Web services.
• Microsoft .NET Compact Framework 2.0 with service pack 2 - It offers a choice of languages, initially Microsoft Visual Basic and Microsoft Visual C#, and eliminates the common problems faced with language interoperability.
• XML - Provides the Document Object Model (DOM) for base XML functionality, support for XML Query Language (XQL) and XPath, Extensible Style Sheet Language Transformations (XSLT) that enables you to transform one class of XML document to another, SAX2 support for event-based parsing of XML documents and includes MSXML Writer, and parsing based on Simple API for XML (SAX) for resource-constrained target devices.
• Winsock 2.2 - Provides enhanced capabilities over Winsock 1.1, including installable service providers for additional third-party protocols, as well as Media sense.

Networking and Communications Capabilities

For network centric embedded application usage, EM-2260, not only provides powerful communication hardware interfaces including dual Ethernet and 3-in-1 serial ports, but also supports the networking and communications capabilities that are built-in to Windows CE 6.0 OS. The features that are well supported are listed as below.

• Simple Network Management Protocol (SNMP) - Monitors remote connections to the network.
• Simple Network Time Protocol (SNTP) Client - Provides support for synchronizing the device's system time with a SNTP server, and supports Daylight Saving Time.
• Serial Communications - In addition to the 16550 UART driver bound to a debug port and the console port, it includes a special driver for 8 additional MOXA home-made serial ports.
• Network Utilities (IpConfig, Ping, Route) - Utilities for troubleshooting various network problems.
• 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, EM-2260 embeds the services and daemons as stated next. These common and easy-to-use application servers help users to migrate the EM-2260 embedded computer to the industrial communication application very easily and conveniently.

• Telnet Server - A sample server that allows remote administration through a standard telnet client.
• FTP Server - A sample server used for transferring files to and from remote computer systems over a network using TCP/IP.
• File Server - The File Server functionality in Microsoft Windows CE enables clients to access files and other resources over the network.
• 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.
• 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.
• 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.

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 EM-2260 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. In the EM-2260 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 50M bytes. You could adjust this size by using the "Control Panel\system". 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".

The additional file systems on USB and CompactFlash storage devices are placed at the root of the internal file system. If you intend to use these devices to port data between your PC and the EM-2260 computer, please format them as the FAT file system on your PC.

System Manager Utility

Operating Your EM-2260 Computer via Telnet Client

Before operating your EM-2260 computer using the Telnet client, we suggest that you change the network settings of the computer (see the earlier section) to have at least one of the two network ports situated in the same LAN as your development workstation.

Use a cross-over Ethernet cable to directly connect your development workstation to the target computer, or a straight-through Ethernet cable to connect the computer to a LAN hub or switch.

Next, use a telnet client in your development workstation to connect to the telnet console utility of the target computer. Upon a successful connection, type the login name and password as requested to logon to the computer.

After logging in via the console port or a telnet client, you have a list of busybox commands available to operate the computer. Use HELP to display all the commands, or type HELP [command name] to display extended help for the selected command. Some of these commands such as DATE and TIME are very useful to you to easily manage the system time of the computer. Other commands such as DIR and MKDIR are good utilities for file management. For example, to inspect the file structure of the root directory, type DIR

\> dir /b
NORFlash
My Documents
Program Files
Temp
Windows 

User/Group Management

User Group: You should assign specific services, such as ftp and telnet, to defined user groups such that these services are accessible only by the users within the permissible user group. Three user groups, namely “ftpd”, “telnetd”, and “httpd”, are already created by default for your convenience.

Adding a Group: Use the command useradd -g to create a user group.

\> useradd -g yyyy
group yyyy has been added. 

Deleting a Group: To remove a group, use the command userdel -g .

\> userdel -g yyyy
group yyyy has been removed. 

Adding a User: Use the command useradd to add a user for accessing the system. The user's password, by default, is the same as the user name.

\> useradd xxxx
user xxxx has been added. 

In addition, you can permit this user to access a particular service by typing -g followed by the user group name of the service, i.e., useradd -g . For example,

\> useradd -g telnetd xxxx
user xxxx is existent
group telnetd is existent
user xxxx has been added to group telnetd 

Deleting a User: Use the command userdel to delete a user from the system. User "admin" CANNOT be deleted.

\> userdel xxxx
user xxxx has been deleted 

You can also remove a user from a user group by using the command userdel -g

<groupName> <newUserID>. For example,
\> userdel -g telnetd xxxx
user xxxx has been removed from group telnetd 

Changing the Password: Please use "System Manager" to change the Password.

Adjusting Time Zone

Windows CE 6.0 supports Time Zone. You can use [Control Panel]→[Date/Time] to adjust your current Time Zone. It also supports Daylight Date and Daylight Time.

Adjusting System Time

Setting the System Time Manually: Use the date, and time commands to query the current system date/time or to set a new system date/time.

\> date
The current date is: Tuesday, November 22, 2005
Enter the new date (mm-dd-[yy]yy): 12-23-05 

\> date /T
Wednesday, November 23, 2005 

\> time
The current time is: 5:27:17 PM
Enter the new time (hh:mm:ss): 16:02:00 

\> time /T
4:02:04 PM 

The Date/Time setting will be saved into EM-2260 RTC, which is powered by battery.

Starting and Stopping Services

After booting up, the EM-2260 computer runs several services continuously to serve requests from users or other programs. Notable services include telnet ("TEL0:"), console ("CON0:"), world wide web HTTP ("HTP0:"), file transfer FTP ("FTP0:") etc. You seldom need to care about these services. However, you still can start up or stop a service with its associated name by using the command "services". For example,

Start the FTP service by
\> services start FTP0: 

Stop the FTP service by
\> services stop FTP0: 

The default services in EM-2260 are listed as below:

TEL0: Telnet Service

FTP0: FTP Service

Simple Network Management Protocol (SNMP)

SNMP is the Internet Standard protocol for network management and part of the TCP/IP protocol suite. SNMP was developed to monitor and manage networks. It uses a distributed architecture that consists of agents and managers:

SNMP Agent

The SNMP agent is an SNMP application that monitors network traffic and responds to queries from SNMP manager applications. The agent also notifies the manager, by sending a trap, when significant events occur.

SNMP Manager

An SNMP manager is an SNMP application that generates queries to SNMP agent applications and receives traps from SNMP agent applications.

The EM-2260 computer installs an SNMP agent to serve as an SNMP device. You should install the SNMP manager on the workstation computer (for example, a Linux system) that monitors the network. After installing the nodes, you need to configure the SNMP manager and agent.

To check SNMP agent capabilities in a target EM-2260 computer (e.g., network IP at 192.168.3.127), please log on the workstation computer that, for example, a Linux-based computer, the SNMP manager resides and type

> snmpwalk -v 2c -c public 192.168.3.127 system

SNMPv2-MIB::sysDescr.0 Microsoft Windows CE Version 6.0 (Build 1400)

SNMPv2-MIB::sysObjectID.0

SNMPv2-SMI::enterprises.8691.13.7420

SNMPv2-MIB::sysUpTime.0 1282929

SNMPv2-MIB::sysContact.0 Your System Contact Here

SNMPv2-MIB::sysName.0 WindowsCE

You will see a series of messages from the SNMP agent in the EM-2260 computer. From there, you can monitor and manage the computer.

Web Server Configuration

You need a Windows 2000 or Windows XP for Web administration. Try to open a "IE" and go to URL http://192.168.3.127/WebAdmin (e.g. the EM-2260 network IP address is 192.168.3.127).

After the logon information you could see the standard Web server Administration page.

This chapter describes how to connect the EM-2260 to a PC for the debugging and testing purposes. For clarity, this PC is called a development workstation and the EM-2260 computer is called a target computer.

The following topics are covered in this chapter:

□ Console Ports
☐ Operating EM-2260 Computer Via Serial Console
☐ Go to Boot Loader Menu from Console
□ Firmware Upgrade Procedure

Console Ports

There is a 4-pin pin-header RS-232 console port designed for serial terminals, which gives users a convenient way of connecting the development workstation (The PC) to the console utility of the target computer (The EM-2260). This method is particularly useful when using the computer for the first time or for debugging while the system cannot boot up. A special Serial Console Cable (Optional) is needed for this function.

ATTENTION

You do not need Console Port to operate this computer. Console Port and Serial Console Cable are only for debugging purpose.

Operating EM-2260 Computer Via Serial Console

Follow the following steps to operate EM-2260 computer via serial console port.

1. Power off EM2260.

2. Connect the serial Console Cable.

3. Go back to the development workstation and start a terminal program (for example, HyperTerminal or PComm) by using the settings shown below for the COM port.

Baud rate	115200bps
Parity	None
Data bits	8
Stop bits	1
Flow Control	None
Terminal	ANSI

1. Power on to cold reset EM-2260, it may takes 30 to 60 seconds for the operating system to boot up.

2. After a successful connection, type the login name and password as requested to logon the computer. The default values are both "admin".

Login: admin

Password: admin

Go to Boot Loader Menu from Console

If the computer is not working properly or the system cannot boot up successfully. You can use following steps to go to Boot Loader menu.

1. Power off EM2260.

2. Connect the serial Console Cable.

3. Go back to the development workstation and start a terminal program (for example, HyperTerminal or PComm) by using the settings shown below for the COM port.

Baud rate	115200bps
Parity	None
Data bits	8
Stop bits	1
Flow Control	None
Terminal	ANSI

1. Hold "DEL" key continuously.

2. Power on EM-2260. You should see below screen in few seconds.

There are four functions:

Reset to Factory Default: You can turn on the flag to enforce the WinCE 6.0 to do the "reset to factory" default.

Format Flash Disk and Reset OS: The WinCE FAT file system has the possibility to be damaged by unstable power or improper application execution. If the FAT table is crashed you may not be able to boot the OS up. In such case, you can try to format the file system and reboot EM-2260.

At the EM-2260 startup, it will check the file system and re-partition it if the file system is empty.

Firmware Update: If you found a new firmware from MOXA web site, you can upgrade the firmware by this function.

TFTP Config: In conjunction with Firmware Update, this function is used to set IP address of both server PC and target system (EM-2260), and to transfer file from server PC to target system.

ATTENTION

There is a very small possibility that unstable power or improper application execution may damage not only FAT file system but also WinCE itself. In such case, you can try Firmware Upgrade (Re-program) and reboot EM-2260 again.

Firmware Upgrade Procedure

To upgrade the EM-2260 firmware, you must have the firmware upgrade installation file. This firmware installation file is included in the released software CD. You can also download it from MOXA Download Center if there is newly released, the URL is listed below.

1. Get the firmware upgrade installation file
   (In this example, EM-2260-CE_V1.1_Build-08011415.hfm).

2. Connect target computer (The EM-2260) to development workstation (The PC) through Ethernet port LAN2.

1. Execute TFTP utility on the development workstation (The PC), and set correct server IP and file directory path. (In this example, 192.168.30.42).

1. Go to the Boot Loader menu from Console. (See the earlier section.)
2. Select "TFTP Config".

1. Next, Select "User Configure".

1. Then, Input Local IP Address (EM-2260) and Server IP Address (TFTP host IP Address).

1. Next, Select "Show Configure" to check configuration of local IP and server IP.
2. After confirm the IP configuration, press [ESC] to go back main menu for next step.

1. Select "Firmware Update".
2. Next, Select "Load from LAN2 (TFTP)".
3. Input the firmware file name (e.g. EM-2260-CE_V1.1_Build-08011415.hfm) and the Press [Enter].

1. The TFTP utility on the development workstation (The PC) and Boot Loader on the target computer will start to transfer firmware file. In the mean time, firmware will be updated automatically.

1. Please wait until the "Command>>" prompt appears again and reboot the system.

ATTENTION

Do NOT switch off power supply during firmware update, otherwise the computer and Boot Loader may crash.
