Format Conventions for Bar Codes

You can scan the bar codes listed in this manual to enter data or perform a
command. The bar code labels in this manual are printed in the Code 39
symbology. Each bar code includes the name and human-readable
interpretation. For example:

Change Configuration

*$+*

Getting Started

Introduction

nuggnuggcd39cd39Getting Started

This chapter provides basic information for setting up and using your JANUS data
collection computer with 900 MHz terminal emulation software.

Your JANUS 900 MHz device with terminal emulation (TE) software is a
DOS-compatible, data collection computer that emulates IBM 3270, IBM 5250,
or VT/ANSI terminals. Your JANUS 900 MHz RF device is shipped to you
ready-to-use with terminal emulation software and special TE keypads (for
3270 and 5250) already installed.

You can use your JANUS TE device to:

• View terminal screens on your JANUS display.

• Enter data into the screens using the scanner or keypad.

• Access host commands and perform host functions.

• Automatically transmit the data to the host.

1

Other features of your JANUS TE device include:

• Auto-login capability.

• Password security.

• Choice of SNA or TCP/IP protocols for IBM terminal emulation.

• 5250 Field Advance configuration.

• Support for display of single byte international character sets.

Typical 900 MHz Configuration

In a typical 900 MHz RF configuration, JANUS devices communicate with a
9181 Base Radio Unit (BRU) using radio frequency (RF) communications. The
9181 communicates with the Model 200 Controller using a serial connection.

Starting Terminal Emulation

Before you can begin using your JANUS device with terminal emulation, you
must start the terminal emulation program. You only need to start the program
the first time you use it or if you exit. The JANUS device resumes terminal
emulation for each data collection session.

To start terminal emulation

nuggnuggcd39cd39Getting Started

1

1. Type te at the DOS prompt on your JANUS device and press

@

to start
the terminal emulation program. The factory installed TE.BAT file loads the
configured TE program(3270, 5250, or VT/ANSI).

2. Wait a few seconds while the display clears and the terminal emulation
program starts.

When the display on your JANUS device shows a login screen (VT/ANSI)
or Sign on screen (3270 or 5250), you are ready to use your device as a
terminal.

Using TE Features

This chapter describes the JANUS TE keypad and explains how to use terminal
functions on the keypad.

Using the JANUS TE Keypad

Your JANUS 900 MHz TE device comes with a special keypad that contains
most of the keys available on 3270 or 5250 terminal keyboards. IBM TE
keypads are similar to the regular JANUS keypads, but have additional
commands that are specific to 3270 or 5250 systems. Many of these additional
commands are accessed through key combinations described later in this
chapter.

You enter VT100/220/320 and ANSI commands using a standard JANUS
keypad.

Accessing the Commands on the Keypad

As on all terminal keyboards, the keys on the JANUS TE keypad have their
main function marked directly on the key itself. To access that character or
function, just press the key. Your JANUS TE keypad provides access to
additional keys and commands. The following paragraphs describe these keys.

Note: When entering a key combination on the JANUS device, you do not need to
press and hold the > , < , M , or A keys. Once you press a key, the keystroke is
stored in memory and is used with the next keystroke as a key combination.

Accessing Uppercase Letters and Symbols

The O key accesses uppercase letters. For example, to type the letter “A” you

O

press

Accessing Characters or Commands

The > and < keys let you access characters or commands on the keypad that
are printed above the letter keys and function keys. The
commands printed on the top left of the alphabetic keys. Similarly, the
activates commands printed on the top right of the alphabetic keys.

the key sequences shown in the JANUS user’s manual become available. For
information on acquiring other keypads, contact your Intermec sales
representative.

Note: Unlike the regular JANUS keypad where you can press the A key multiple
times to access even more sets of commands, you cannot access multiple commands by
pressing the A key in TE.

Viewing the Input Screen

When you start terminal emulation, you see all or part of an input screen on
the JANUS TE display. This section describes how you access other parts of the
input screen when you are not operating in Full Screen mode and how to enter
data into input fields.

The JANUS TE 16 x 20 display shows only part of each 25 x 80 screen that
appears on a full-sized terminal. You can use the JANUS TE display to access
the full screen by using the viewport movement functions described on the
following pages. This guide uses the following terms to describe the TE
display.

Screen Refers to a full 25 x 80 screen that appears on a standard terminal
display.

Viewport Refers to the 16 x 20 JANUS TE display. The viewport shows only a
portion of the 25 x 80 screen and you can move it around to show different
areas of the standard terminal display.

nuggnuggUsing TE Features

2

Note: There are several display exceptions for non-EBCDIC keypad characters when
you are working in Terminal Emulation mode. Brackets [ ](
appear as parentheses ( ). You cannot use the ^ character (

> )

O 

and

> *

) in TE mode.

)

How the Viewport Works

The viewport lets you view screens and enter data by showing the part of the
screen you are using. When you need to access part of a screen that does not
appear on the viewport, the viewport changes its display to show the part of
the screen you need. The viewport acts as a window to the larger screen, and
when it changes its display, it behaves as if it were “moving” across the screen.

Viewport movement functions are useful for viewing text that is outside of the
viewport boundary or for viewing error regions on the TE display. Refer to
your JANUS user’s manual for a detailed explanation of viewport movement
functions.

Note: When you are using TE, the viewport automatically moves to the cursor when
there is data entry from the host or the terminal.

Understanding the Roll Command

5250 terminals support the Roll command (Hex 23) received from a host
application. Using this command, a host application can roll an area of the
screen up or down. The direction of the Roll and number of lines to Roll, are
specified in the command.

The Roll command should not be confused with the Roll keys. The Roll keys
cause the host to send down additional screens when you are at a Roll screen.
A Roll screen typically has text in the lower right hand corner of the display
indicating there are additional screens to view. For example, the text “More

.....” or “+” in the lower right hand corner of the display indicates that you can

press a Roll Up key to view additional information.

• A Roll command received from a host application moves the screen, but not

the viewport. You can see the screen scroll through the viewport when you
roll up or down, but the viewport itself remains stationary.

• Use the Paging keys (page up, page down, page right, page left) to move

the viewport within a screen; they do not move the screen itself.

For more information on the roll up and roll down keys and paging keys, see
Chapter 3, “3270 and 5250 Commands.” For more information on the Roll
command, see the IBM 5494 Remote Control Unit Functions Reference Manual.

nuggnuggUsing TE Features

Auto-Advancing Through Fields on 5250 TE Screens

You can set up your JANUS device so that when you scan data into a field on a
5250 TE screen, a Field Exit command clears the rest of the field, advances to
the next field, and triggers an auto-enter field to send an Enter to the
application and submit the data. Using the auto-advance feature, you can just
scan data and never touch the keypad.

To set up auto-advance for bar code scanning

1. To configure your JANUS device for auto-advancing, you need to set the

Postamble command to the 5250 Field Exit code. The 5250 Field Exit code
on your JANUS device is mapped to a PC backspace character.

Note: You configure preamble and postamble with the JANUS configuration
application (IC.EXE). Preamble and postamble are disabled with the default
configuration. See your JANUS user’s manual for information on using the
JANUS configuration application.

2

2. Use the terminal configuration screen to toggle the Auto Field Advance

setting to Disable. This disables the normal auto-advance feature so that the
cursor does not automatically move to the next field on the application
screen when a character is entered in the last character position of the field.

The Disable Auto Field Advance setting functions as if the field has a
mandatory field exit turned on (an AS/400 activated feature known as
Check FE). As a result, legacy AS/400 applications do not have to be
modified to turn this field on properly for bar code support.

Note: The default setting is Auto Field Advance enabled.

3. Save your new configuration.

Understanding Status Line Messages

A status line is provided for JANUS devices configured as 3270 or 5250
terminals. Status messages are displayed on the status line and report the
operating status of both the JANUS device and the host system or work station
controller.
