Features of the MX1 Intrinsically Safe Hand Held Computer

Introduction

This document provides safety instructions, warnings, and regulatory compliance information

important for the safe operation and use of the LXE® model MX1 Intrinsically Safe (MX1-IS)

Hand Held Computer within hazardous environments.

Figure 1 The MX1-IS Hand Held Computer

Note: Although there is an IR window and four battery charger connectors on the bottom of the

MX1-IS device, these capabilities are non-powered and non-functional. There is no

backup battery in the MX1-IS device.

The MX1-IS is a rugged, portable, hand-held computer capable of mobile wireless data

communications. The MX1-IS can transmit information using either a 900 MHz or 2.4 GHz radio.

The MX1-IS has a mandatory protective leather case and pistol grip handle. The leather protective

case allows the scanner aperture, scanner status indicators, system status indicator, display, keypad

and pistol grip trigger to be accessible to the user. The Main Battery Pack can be removed and

replaced without removing the leather case or the pistol grip handle.

The MX1-IS is a DOS compatible computer designed to run software applications such as LXE’s

Terminal Emulator applications (ANSI Plus, LDS Plus, DOS 5250, DOS 3270, TN3270 and

TN5250).

The heart of the MX1-IS is an Intel® 486 processor that is PC compatible. It features a graphics

screen with electroluminescent backlight. The keypad is constructed of a phosphorescent material

that needs no backlighting. The high-impact plastic case is designed to withstand multiple drops in

an industrial environment. The MX1-IS can be stored in a non-powered docking station on a desk

or a vehicle.

Note: The 900MHz radio is obsolete. Terminal emulators requiring 900MHz radios are

obsolete as of June 2005 (e.g. 3270 DOS TE, 5250 DOS TE).

Display 7

E-EQ-MX1ISOGWW-J MX1 I-Safe User’s Guide

Display Backlight

A display backlighting feature is available and depending upon programming, will operate in one

of three ways:

• Backlighting Off. This is the most efficient way to operate the computer with battery

power.

• Backlighting On For A Short Time. This will provide display backlighting for a

predetermined amount of time. Use of this feature will result in reduced battery life.

• Backlighting On Whenever The Unit Is On. This provides full time backlighting to the

display whenever the unit is turned on. It greatly reduces the expected battery life.

Display Backlight Timer

When the Display Backlight Timer expires the display backlight is turned off. The default value

for this parameter is 3 seconds. The value can be adjusted using the BIOS Setup. Refer to the

“MX1 I-Safe Reference Guide.”

Any of the following will wake the display and display backlight:

• Display update by host or currently running application on the MX1-IS

• Trigger

• Any key on the keypad

When the display wakes up, the Display Backlight Timer will begin the countdown again. When

any of the above events occur prior to the timer expiring, the timer starts the countdown again.

Panning

The MX1-IS display can be panned around using keypress sequences so the user can view an

entire virtual 640 x 480 pixel screen. Initially, the 20 columns and 20 rows in the top left corner of

a virtual screen are displayed.

8 Intrinsically Safe Endcap

MX1 I-Safe User’s Guide E-EQ-MX1ISOGWW-J

Intrinsically Safe Endcap

The MX1-IS can be configured with several different laser scan-range endcaps. Endcaps are

mounted on the top of the computer case and contain the beeper. The endcap port is designated as

COM 1.

Read all cautions, warnings and labels before using the scanner.

Important

See also section titled “Scanner Warnings and Labels.”

Scanner Endcap

Several scanner endcaps are available with the MX1-IS. These consist of a High Performance,

Long Range, and Advanced Long Range scanner endcaps. Externally they appear identical with

the same indicators. Barcode Scanner operation varies depending upon the application but, once

enabled, the scanners are activated by pressing either the “Scan” button on the keypad or pulling

the trigger on the handle.

Figure 8 Scanner Endcap

The range of a scanner is dependent upon many outside influences including size of the barcode,

quality of the barcode printing, material the barcode is printed on, and angle of the scanner endcap

relative to the barcode label. Any of these factors may result in having to re-scan the label from a

different distance or angle.

Scanner Endcap Indicators

Read all cautions, warnings and labels before using the scanner endcaps.

1 – Laser On Indicator

2 – Beeper

3 – Good Read Indicator

Figure 9 Scanner Endcap LEDs and Beeper

The left LED (1 - Laser On Indicator) on the top of the laser barcode endcap illuminates red,

indicating laser emission when the laser beam is being emitted. Following a good read, the right

LED (3 - Good Read Indicator) flashes green, indicating a successful scan. Beeps may be heard

after a good read, depending on the application running on the MX1-IS.

The laser automatically turns off after a successful read and is ready to scan again when the Scan

key (or the trigger) is pressed.

Keypad Controls 9

E-EQ-MX1ISOGWW-J MX1 I-Safe User’s Guide

Keypad Controls

There are two keypads available for the MX1-IS. All keypads are phosphorescent. A

phosphorescent keypad does not use a keypad backlight but glows in dim/dark areas after

exposure to a light source.

All keypads are installed and configured by LXE. Full alpha-numeric (60 key) keypads are

available that are directly suited to ANSI, IBM 3270 and IBM 5250 host computer systems.

The Field Exit key is used to exit an input field. If the field is an Auto Enter field, the

auto transmit function is activated. This key is present on the IBM 5250 specific keypad only.

Arrow / Cursor Key Function

The arrow keys (also called the cursor movement keys) are used to scroll through the

active display or to move the cursor around the screen.

Keypad Controls 11

E-EQ-MX1ISOGWW-J MX1 I-Safe User’s Guide

2nd Key Function

The 2nd key is colored yellow and is used to activate the 2

nd

functions of the keypad.

Printed above many keys are yellow characters that represent the 2

nd

function of that key. Using

the 2

nd

key activates the second key function. Note that the 2

nd

key only stays active for one

keystroke. Each time you need to use the 2

nd

function you must press the 2

nd

key. To cancel a 2

nd

function before pressing another key, press the 2

nd

key again. When the 2

nd

function is active, the

2

nd

icon stays on the screen.

For example:

• Full Alpha-Numeric : 2nd plus the I key initiates INSERT mode.

• Numeric-Alpha : 2

nd

plus the SPC key initiates ALT mode.

CTRL Key Function

The CTRL key enables the control functions of the keypad. This function is similar to a

regular keyboard’s Control key. Note that the Ctrl key only stays active for one keystroke. Each

time you need to use a Ctrl function, you need to press the Ctrl key before pressing the function

key. When the Ctrl function is active, the Ctrl icon stays on the screen.

ALT Key Function

Note: Full alpha-numeric keypad only.

The ALT key enables the alternate functions of the keypad. This function is similar to a

regular keyboard’s Alt key. Note that the Alt key only stays active for one keystroke. Each time

you need to use an alternate function, you need to press the Alt key before pressing the function

key. When the Alt function is active, the Alt icon stays on the screen.

SHFT Key Function

The Shft key enables the shifted functions of the keypad. This function is similar to a

regular keyboard’s Shift key. Note that the Shift key only stays active for one keystroke. Each

time you need to use a Shifted function, you need to press the Shft key before pressing the

function key. When the Shft function is active, the Shft icon stays on the screen.

When the Shft key is pressed the next key is determined by the major key legends, i.e., the alpha

keys display lower case letters when CAPS is On and function keys enable the shifted function

key.

SPC Key Function

Note: Numeric-alpha keypad only. SPC is a 2nd function on the full alpha-numeric keypad.

The Spc key adds a space to the line of data on the display. This function is similar to a

regular keyboard’s Spacebar. Note that the SPC key only stays active for one keystroke.

12 Keypad Controls

MX1 I-Safe User’s Guide E-EQ-MX1ISOGWW-J

Mode Key Functions

CAPS Mode

This function is similar to a regular keyboard’s CapsLock key. Note that the CapsLock mode stays

active until the CapsLock key sequence is pressed again. Each time you need to use a Caps

function, you need to press the Caps key sequence first. To cancel a CapsLock function press the

Caps key sequence again. When the CapsLock mode is active, the Caps icon stays on the screen.

Caps mode on both keypads is accessed through the key sequence 2

nd

plus Shft plus Left arrow.

Alpha to Numeric Toggle with A / #

Note: Numeric-alpha keypad only.

When the keypad is in Alpha mode, the Alpha icon stays on the screen. When the Alpha

icon is not displayed, the keypad is in numeric mode. Note that the Alpha or Numeric mode stays

active until the A / # key is pressed again.. To toggle the A / # mode press the A / # key again.

The exception to this rule

-- when the keypad is in numeric mode and you want to type one alpha

character within a sequence of numbers, pressing 2

nd

plus Ctrl and then the A / # key will toggle

the keypad to alpha mode for one character – the next key pressed. Then the keypad returns to

numeric mode. Likewise for toggling alpha to numeric for one key only.

Keypress Sequences

See Appendix A for key maps for the alphanumeric and numeric-alpha keypads. MX1-IS specific

key maps for the 3270 and 5250 keypads are contained in the 3270 and 5250 DOS Terminal

Emulation Reference Guides.

Reset Key Sequence

Reset Key Sequence is Ctrl + Alt + Del.

• Del is a 2nd function on the full alpha-numeric keypad.

• Alt is a 2nd function on the numeric-alpha keypad.

The Reset Key sequence can be disabled in the BIOS Setup. See the “MX1 I-Safe Reference

The Power button is used to turn the MX1-IS on and off and force it into the Suspend state. The

button will beep when pressed and beep again every second while it is held down.

How To

• Turn the MX1-IS off

Hold the Power key down for 4 beeps (signifies 3 or more

seconds) then release.

• Turn the MX1-IS on

Hold the Power key down until the display turns on.

• Force the Suspend state

Tap the Power key (1 beep). The Suspend state is useful for

breaks or brief periods when the unit will not be used.

• Wake from Suspend

Tap the Power key to wake the MX1-IS from Suspend

(before the 5 minute timer expires).

Off Timer and Critical Suspend Mode

The MX1-IS is automatically turned off when the Off Timer expires. The Off Timer runs when the

MX1-IS is in Critical Suspend mode. The MX1-IS automatically goes into Critical Suspend when

the Main Battery is reaching the critical power mark. The Off Timer default is 5 minutes. The

value can be adjusted using the BIOS Setup.

Important:

The MX1-IS Main Battery must be replaced when the unit enters Critical Suspend.

Turn the unit off before replacing the Main Battery.
