Introducing the M71V2

This chapter describes how to get started using your M71V2 handheld terminal and get you up and running fast.

The M71V2 handheld terminal is an ultra-versatile, high-performance, designed-to- fit-your-budget terminal. The ergonomic design easily fits in even the smallest of hands. It is rugged, lightweight, compact and easy-to-use. The high resolution

graphical display is capable of presenting a multitude of fonts and images.

The M71V2 utilizes a true, fully functional, Linux operating system. The Linux operating system is well known for its stability, speed and conservative memory usage. The Linux operating system coupled with the M71V2’s high speed processor makes the M71V2 one of the fastest handheld terminals on the market today. In test after test the Linux operating system has out-performed DOS based and Windows based operating systems when compared on similar hardware platforms.

The M71V2 is easy to use and program. Our specifically designed CommandLink™ RF (Radio Frequency) software makes it easy to create custom applications for any requirement. Our terminal emulation software makes it easy to integrate the M71V2 into legacy applications as well. You can even utilize standard BASIC software on the M71V2 handheld terminal.

Power saving features of the M71V2 includes auto-off and power save modes, which reduce power consumption until an operator provides input. These features conserve battery power and lengthen the time between charges or battery replacement. The M71V2 was designed to operate for a full 8 hour shift without requiring the battery to be recharged or replaced.

o save time in the future, print a copy of this document. Choose Print from the File menu, and Tpress Enter to receive all the pages of examples and instructions.

Using the M71V2 Keyboard

The M71V2 Terminal is equipped with fifty-five keys that are divided into white, grey, blue, red, yellow and black keys. When pressed, each key emits an audible beep to indicate that the M71V2 terminal has detected the key press.

The red power key turns the M71V2 on/off. You must press and hold this key down to power off the unit. This prevents accidentally powering off the unit if this key is momentarily pressed.

Note: The Power Key Wake-up feature is only available on units with Decoder version 2.0 or later. On earlier versions the power key will immediately shut off the unit. The Decoder can only be programmed at the factory.

The white/black “light bulb” key turns on/off the display backlight. The backlight will automatically shut off after a predetermined time has expired. This predetermined time can be programmed by the user.

The yellow [SCAN] button activates the M71V2 scan engine. The button is conveniently located for right or left hand use.

The seven blue keys consist of [Func], four arrow keys and two [ENTER] keys (for right or left hand use). The [Func] key activates

3

the blue Function menu or the blue special characters. Function keys (F1 – F20) can be programmed by many host systems, to be “hot keys” and select specific program items without navigating the entire program.

The black [Shift] key toggles between upper and lower case mode and selects special characters on the numeric keypad.

There are ten white numeric keys and one white period key. These keys are larger than the less used alpha keys to enable easy inputting of numbers with the right or left thumb.

Thirty-three grey keys represent letters, special functions, Space and Menu keys. The [Alt], [Ctl], [Ins], [? ¦ ] (backspace) and [Esc] keys are also grey keys near the bottom of the keyboard.

The M71V2 Display Screen

The M71V2 handheld terminal includes a 160 pixel by 160 pixel grayscale graphical Liquid Crystal Display (LCD). Programs can be written which mix text and graphics together on the display.

Warning: This display is NOT a touch screen display and the operator should not use sharp objects on the plastic window protecting the LCD display.

The M71V2 Scanner

The M71V2 handheld terminal normally comes equipped with a scan engine that is capable of scanning single dimensional bar codes. An optional Area Imager is available for 2 dimensional bar codes. The M71V2 can be ordered with one of the following scan engines installed:

Standard Range Laser

The Standard laser engine uses a moving laser and a standard laser detector. The standard laser is suitable for most applications. The laser is easy to aim and reads most barcodes very quickly.

Scan Rate:

35 (± 5) Scans / Second

Scan Angle:

42º ± 2º

Min. Print Contrast:

Minimum 20% absolute dark/light reflectance measured at 650 nm

Long Range Laser (LR)

The Long Range laser engine uses a moving laser light with a highly sensitive laser detector. The long range laser is used when the barcodes are going to be a great distance from the operator. The long range laser includes a laser point (dot) feature to make it easy for the operator to aim at the barcode before it starts to read.

Scan Rate:

35 (± 5) Scans / Second

Scan Angle:

23º ± 2º

Min. Print Contrast:

Minimum 40% absolute dark/light reflectance measured at 650 nm

6

Advanced Long Range Laser (ALR)

The Advanced Long Range laser engine uses a moving laser light with a highly sensitive laser detector. The advanced long range laser is able to read farther than the standard long range laser. The advanced long range laser also includes a laser point (dot) feature.

Scan Rate:

35 (± 5) Scans / Second

Scan Angle:

13º ± 2º

Min. Print Contrast:

Minimum 40% absolute dark/light reflectance measured at 650 nm

Area Imager (2D)

The Area Imager uses a camera type sensor to acquire images of the target. Unlike a linear scanner, the imager is able to scan barcodes in any orientation. The HHP Imager is also capable of reading most 2D barcodes and Postnet barcodes.

Barcode symbologies are always measured in mils. This usually refers to the narrowest bar width. One mil equals 0.001”, therefore a 0.01” wide narrow bar would be a 10 mil barcode.

Conversion: 1 mil = 0.0254 mm

1 inch = 25.4 mm

These charts show typical performance at 68°F on high quality bar code symbols.

The M71V2 Scanner LED

The M71V2 has a multi-color LED to indicate when the unit has scanned a bar code successfully. When the scan button is pushed, the LED above the on/off button will turn a solid red. Once the scanner has successfully read the bar code, this LED will turn a bright green.

This visual indication of a good read is useful in very noisy environments where the audio beeper can not be heard. If the red LED turns off, it means the bar code can not be read.

Note: On units built before February 2004, there was only a red LED when an item was scanned.

Note: When the M71V2 is in sleep mode the scanner LED will be flashing red. You can press any key to re-activate the unit.

The M71V2 Internal Radio

The M71V2 Handheld Terminal comes equipped with an internal 802.11b radio and antenna. This internal radio is specifically designed to communicate with any 802.11b Access Point. The range of the internal radio depends greatly on the quality of the Access Point and the RF communications characteristic of the environment where the device is used. The typical range for an 802.11b radio is 500 feet through free air. Additional Access Points must be added to improve coverage in a larger area, or in electrically noisy RF environments.

802.11b Fallback Mode

Wireless LAN technology is designed to make maintaining a connection between two devices as reliable and consistent as possible. Since the speed of the connection between wireless devices will vary as range and signal quality varies, the wireless devices will intentionally sacrifice throughput (data rate or connection speed as measured in bits per second) in exchange for maintaining a reliable connection. In other words, a reliable connection at a lower speed is preferred over an unreliable connection at a higher speed (i.e., it is easier to maintain the connection if data rate is deliberately reduced, or put another way, lower data rates will tolerate a higher range and/or worse signal quality). This characteristic is known as fallback. As example, an 802.11b system will fallback from 11 Mbps to 5.5 Mbps as range increases or signal quality decreases. Subsequent fallbacks from 5.5 Mbps to 2 Mbps and 1 Mbps are also supported

Interference and Coexistence

802.11b operates in a range of radio frequencies known as an "unlicensed" band (i.e. the FCC does NOT require the use of a license in order to operate a radio transmitter in this range). This means that commercially available radio devices other than wireless LAN devices are permitted to use the same frequency band as 802.11b. Consequently, these co-existing radio devices can interfere or "jam" the wireless LAN (and vice versa). Ironically, the most troublesome devices are cordless telephones and microwave ovens.

Fortunately, higher quality cordless phones tend to "listen" for a clear channel before becoming active and will thus avoid interfering with a wireless LAN (i.e., the cordless phone seeks a clear channel for itself so naturally avoids being interfered with or being a source of interference). Jamming from microwave ovens is more severe but is usually restricted to the upper frequency range for 802.11b (it should be noted that 802.11b divides the available frequency band into 11 channels. The higher numbered channels are most susceptible to microwave oven interference).

In each instance, jamming occurs only when the cordless telephone or microwave oven is active.

Security Issues

Much has been publicized in the media about security problems with wireless LANs. Although it cannot be denied that the encryption algorithms currently used in 802.11b are flawed, the fact is that security breaches of a wireless LAN require a deliberate attempt to access the network by an intruder. It is highly recommended that WEP encryption be used and in some cases the access

The Optional M71V2 Handle

The M71V2 has an optional “pistol grip” style handle for users who prefer the point and shoot style. The M71V2 handle is secured to the M71V2 handheld terminal by 4 screws. The battery is then relocated in the handle for easy change-out.

Installing the Optional M71V2 Handle

To install the M71V2 handle, remove the M71V2 battery cover and store in a safe place. Remove the M71V2 battery and set it aside. Remove only the 2 screws in the bottom of the battery compartment. The M71V2 Handle comes with the necessary 4 screws to secure it to the M71V2 unit. Do not over-tighten the 4 screws. Once the handle is securely fastened, insert the battery into the bottom of the handle with the contacts towards the M71V2 handle. The battery is held into place by the spring latch. Install the battery handle door on the bottom of the handle. Never use the M71V2 handle without the battery door in place.

The M71V2 Cradle

The M71V2 Handheld Terminal has available, an optional charging and communications cradle. The cradle automatically charges the M71V2 battery while it is resting in the cradle. The cradle also includes an extra slot to charge a spare battery. The M71V2 cradle can accommodate the M71V2 with or without the optional M71V2 handle.

The M71V2 Cradle has three indicator lights:

POWER - Indicates that the M71V2 Cradle is plugged in.

MAIN - Indicates the M71V2 main battery is charging.

SPARE - Indicates the spare battery is charging.

When the battery charging LED is red, the battery is charging. When the battery charge LED is green the battery is fully charged. A fully discharged battery takes about 6 hours to completely recharge.

22

The M71V2 Cradle’s Communication Ports

The M71V2 handheld terminal has 2 different styles of communications ports, RS-232 (RJ-45) and USB (Type II). The M71V2 Cradle also has 2 communications ports, RS-232 (DB-9) and USB (Type II). The M71V2 Communications Cradle uses a standard RS-232 (DB-9 Male – DB-9 Female) cable.

Both communication connectors on the back of the M71V2 cradle are wired “straight through”. This means that the communications settings on the M71V2 handheld terminal will determine the settings on the communication cradle. The M71V2 Cradle has no internal or external settings that can be changed.

The slower RS-232 communication port is primarily used for uploading and downloading of data files to the M71V2 Batch handheld terminal. File transfers for the M71V2 RF handheld terminal can be done using FTP. For more information on FTP see the “FTP” section of this manual.

The high speed USB data port is used to load a new or updated operating system into the M71V2 handheld terminal only. Use the AML USB Flash utility software to load the operating system.

The CommandLink™ Software

The CommandLink™ software allows a Windows based PC to become an RF server. An RF server is a master control PC that tells the M71V2 handheld terminal what to display and what to do with collected data. If your network already has an RF server then you may choose to login into that server. Many servers use a Telnet session to connect them to their client devices. By default, the M71V2 starts a telnet session when it is first turned on. For more information about telnet, see the Telnet section of this chapter.

Wait WLAN

The following screen shows the M71V2 handheld terminal waiting to find a Wireless Local Area Network (WLAN).

24

If there is not a wireless Access Point (AP) for the handheld terminal to connect to, then the terminal will not proceed past this point. For help in determining the presence and strength of an Access Point’s transmission see the Network Diagnostics section of this manual.

Connecting

The following screen shows the M71V2 handheld terminal connected to an Access Point. The MAC address number for the access point is displayed at the bottom of the screen. After the M71V2 handheld terminal connects (associates) with an access point, it attempts to connect to an active CommandLink™ Server.

Note: If there is not an RF Server active for the M71V2 handheld terminal to connect to, then the terminal will not proceed past this point!

Login

The following graphic shows a typical login screen for the CommandLink™ RF server. If you are using your own server, the login screen will be different. For help in determining the presence of a CommandLink™ Server see the CommandLink™ documentation.

If the User ID or Password is not listed on the CommandLink™ database a Login Error screen will appear.

25

Applications

If you are using the CommandLink™ software, and the proper User ID and Password are entered, then the Applications Menu is displayed. These are the programs that are available on the CommandLink™ Server for this user. Other users may see other programs depending on the settings in the CommandLink™ Administrator.

Additional programs can be created and modified by using the CommandLink™ Developer. Refer to the CommandLink™ documentation for instructions on how to use the CommandLink™ software.

Telnet

For users who have their own Telnet applications, the M71V2 handheld terminal can be setup to simply run a telnet session.

In the above examples, it was assumed that the M71V2 would be connecting to a CommandLink™ RF server. If you would like to connect to your own telnet server, the procedure is exactly the same. To run your telnet session you would simply enter the IP address of your telnet server. An instruction on setting the IP address is explained under the section “Connection Settings” of this manual.

Once the M71V2 handheld terminal has successfully attached to a wireless network, it automatically attempts to start a telnet session. The server address and parameters for making this connection are listed under the Connection Settings menu of the M71V2 handheld terminal.

Switching Virtual Consoles

The LCD screen and the keyboard are collectively referred to as the console. To let you interact with several applications all at once, the M71V2 permits multiple sessions to be run concurrently on consoles by means of virtual consoles. The virtual consoles are defined as follows:

Console 1: Menus

26

Console 2: Communications Session or User Program Console 3: Battery Warnings

Console 4: Second Telnet Session Console 5: Linux prompt

Console 6: User Defined

Console 7: RESERVED

Console 8: User Defined

Console 9: RESERVED

Each virtual console is running a different foreground application that uses the entire screen. The keyboard is attached to the virtual console that's currently visible. You can switch from one virtual console to another - and thus from one application to another - by entering the following key strokes.

To switch to a different console, press the [Alt] then [Func] and a number key corresponding to the Console number. The keys should be pressed one key at a time, not all at once.

Terminal Emulation

The M71V2 handheld terminal has three types of terminal emulation software installed as default. They are amlterm, VT100 and VT220. There is also a Custom option which is described later.

The amlterm terminal emulation software is specifically designed to work with the CommandLink™ software. The CommandLink™ software controls the functionality of the terminal from the CommandLink™ RF server. The CommandLink™ RF server runs on a Windows based PC connected to the same LAN as the access points. In this mode the CommandLink™ RF server controls all of the terminal’s functions.

The VT100 and VT220 terminal emulation is for other types of RF servers. When using these two terminal emulation software types, the menus change to allow the terminal to be setup manually to perform custom features such as font size, scrolling options and virtual display size.

The Custom option allows you to set a custom terminal name for the M71V2 which will be sent to the server during connection. The terminal emulation will still be set to VT220.

The expanded memory version of the M71V2 supports 5250 and 3270 terminal emulation with optional software. Custom screen mapping and keyboard redefinitions are also possible with this optional software.

27

The M71V2 has a built-in feature which makes it easy to see when the terminal is out of range of an access point. When the M71V2 goes outside of RF coverage, the following screen appears. When the operator goes back into RF coverage, the “Out of Range” screen will automatically disappear and return the operator to where they left off. This feature is only available when using the built-in terminal emulations described above.

Instructions on selecting the terminal emulation type are described in the Connection Settings section of Chapter 4.

Updating Firmware

The M71V2 has a built-in web server function which makes updating the firmware very simple. If your M71V2 handheld has a firmware version of 1.0.1 or later, you can flash the handheld over the RF network using a standard web browser. The files will be transferred to the M71V2 unit over the RF link and no cables or other software is required. For units with an earlier firmware version, the USB flash utility is required which can be downloaded off the AML website.

To upgrade the M71V2 firmware, the handheld must be on, and connected to the same network as your PC. Open your internet web browser (for example, Internet Explorer) and type the IP address of your M71V2 handheld into the Address box. Once you have successfully connected to the M71V2 you will see a green AML screen (this is generated and sent to your PC by your M71V2 unit). Select the "Reprogram Device Firmware" link. At the bottom of this page, you will see several file options. For each file type, use the radio button to select the type of file being flashed, then attach the file using the browse button (do not unzip the "rdiskxx.gz" file for this operation). Finally, click Submit to start the process (do not turn the power off on your M71V2 until the flash process is completed). When finished, the unit will either create a green OK screen or a red error screen based on the results. If there are errors, try sending the file again before power cycling the unit. If the RF flash utility fails to re-flash the M71V2 unit for any reason, use the USB utility to re-flash the unit, available on the AML website (www.amltd.com).

Note: The latest firmware files can be downloaded off the AML website.

The M71V2 Menu System

This chapter describes the Main Menu functions of the M71V2 Handheld Terminal.

Main Menu

ou may access the menu system by pressing the [Menu] key on the M71V2 Y handheld terminal. The menu screens pop-up in front of the currently displayed screen. Only the items in the menu screens are active when the menu items are

displayed.

The menus can be navigated by using the up and down cursor keys. A selection is made by pressing one of the two [ENTER] keys on the M71V2 handheld terminal. The [ESC] key will always exit the current menu.

Reconnect

The reconnect option forces the handheld to reconnect to the CommandLink™ RF server. This is useful if the connection is stalled for whatever reason.

29

Contrast

The contrast can be set by selection the “Contrast” function from the Main Menu. The 3(left) and 4(right) arrow keys can be used to fine-tune the contrast.

The scroll bar below the Main Menu window shows the current contrast level.

The [ENTER] key will save the changes to the permanent flash memory and [ESC] will abandon changes.

30

Network Setup

By selecting the Network Setup function from the Main Menu the wireless network adapter can be configured. The “Network Connection Info” dialog box displays the RF Status (RF) the current IP Address (IP), Network Mask (MASK) and the MAC Address (MAC) of the wireless Ethernet card that is installed in the M71V2. The RF Status is described in more detail in the Diagnostics portion of this manual.

The standard network settings are changed by hitting the [ENTER] key while the Network Settings menu item is highlighted.

The user will see one of the three screens shown above. If the wireless local area (WLAN) network has a Dynamic Host Configuration Protocol (DHCP) server attached to the network, then the DHCP function can be used. To select the DHCP function, simply use the arrow keys to highlight the DHCP button. If your network uses the BOOTP protocol then highlight that button. Note that when using DHCP or BOOTP, several of the items below are missing. This is because the DHCP server or the BOOTP server will automatically assign these values. If the wireless WLAN does not use the DHCP or BOOTP functions, then the user must type in the appropriate values for the M71V2 handheld terminal to communicate.

Warning: These values are unique for each network and are assigned by your local Systems Administrator. Improperly setting these functions or values will cause the M71V2 to fail to communicate and can cause problems with other network devices.

31

Note: Enabling DHCP or BOOTP will cause the M71V2 handheld terminal to take slightly longer to establish a connection to the RF network due to the overhead involved in obtaining network information from the server.

Radio Settings (WEP)

The Radio Settings allows the operator to set wireless network security settings.

The first radio setting is SSID (Service Set Identifier), a 32 character unique identifier attached to the header of packets sent over a WLAN that acts as a password when a mobile device tries to connect to the network. The SSID differentiates one WLAN from another, so all access points and all devices attempting to connect to a specific WLAN must use the same SSID (SSID’s are CASE sensitive)!

You can leave the SSID blank and the M71V2 will match to any access point regardless of its SSID as long as the WEP settings match.

Because an SSID can be sniffed in plain text from a packet it does not supply any security to the network.

An SSID is also referred to as a Network Name because essentially it is a name that identifies a wireless network.

32

In the example above, “AMLBURNIN” was chosen for the unique SSID name. Your unique name should be assigned by your local Systems Administrator.

The wireless security settings are referred to as WEP (Wireless Equivalent Privacy) can be left un-enabled or can be enabled from this menu. It is HIGHLY recommended that some sort of WEP standards be enabled in any wireless network. This information is unique for each network and should be assigned by the local Systems Administrator.

The M71V2 handheld terminal supports both 40 bit and 128 bit WEP key encryption. Note that the number of key sets change according to which format is chosen.

The Key ID determines which key set is currently in use. Only the Key ID set selected will be used, all other key sets are ignored.
