E-SW-LDSPLUSRG-G LDS Plus Reference Guide
Chapter 1 Introduction
About this Guide
The LDS Plus Reference Guide provides a description of the use and operation of the LXE LDS
Plus terminal emulator (TE) in an LXE system. LDS Plus is designed for LXE certified DOS
computers operating in an LXE LDS I environment. The LDS Plus TE software program runs on
LXE DOS platforms that operate with the 2.4 GHz radios. Narrowband radios are not supported
in LDS Plus.
As the reference for LXE's LDS Plus, this guide provides detailed information on its features and
functionality. Use this reference guide as you would any other source book: reading portions to
learn about LDS Plus, and then referring to it when you need more information about a particular
subject. This guide takes you through all aspects of the installation and configuration of the LXE
LDS Plus TE.
Note: For details concerning LXE certified DOS devices and future capabilities, contact the
LXE Product Marketing department.
LXE Legacy Terminals vs LXE DOS Computers
The 900 MHz radio system is obsolete. Please see “Getting Help”, later in this
chapter, for information regarding this radio system and the LDS Plus terminal
emulation.
Devices used in the LXE Legacy LDS I system (LXE 1280, 1290, 2280, 2285, 2286 and 2315
terminals and the 5460 wireless modem) are frequently called “LXE RF terminals”.
To distinguish between the Legacy LDS I terminals and LXE certified DOS computers required
for LDS Plus (e.g. 13XX vehicle mount and MXX hand held computers) this reference guide
refers to LDS Plus devices as DOS terminals or DOS computers.
2 About this Guide
LDS Plus Reference Guide E-SW-LDSPLUSRG-G
In This Guide
Chapter 1, “Introduction”, describes this reference guide’s structure, the function and layout of
an LXE Radio Frequency Data Communication system, an overview of the LDS Plus TE system,
and describes RF backbone compatibility with LDS Plus.
Chapter 2, “Getting Started”, takes you through installation, initial setup of the LDS Plus
software and system, and logging in. Instructions are included for using LDS Plus key sequences,
manipulating the Compose and Receive buffers and working with forms.
Chapter 3, “Configuration Utility”, contains information and instructions relating to the
configuration utility resident in each LDS Plus device. Configuration parameter instructions are
included in this chapter.
Chapter 4, “Messages”, presents information and instruction for the host programmer when
working with LDS Plus messages. It includes information and instruction for LDS Plus inbound
and outbound messages, broadcast messages and protocol messages.
Chapter 5, “Expanded Functions”, presents information and instruction for the host
programmer when creating messages using CTRL characters and N/EF characters.
Appendix A, “LDS Plus Screen Messages”, contains an alphabetical list of LDS Plus messages;
general information, error messages and fatal error messages. The expected user response to each
message is included.
Appendix B, “Files”, outlines the LDS Plus file structure on a DOS computer running LDS Plus
and includes examples of important files.
Appendix C, “Code Tables and Character Sets”, contains graphics and tables portraying
decimal - hexadecimal equivalent values, CTRL Bit Patterns, Form and Non-Form characteristics,
the list of National Replacement Sets (NRC Sets), the 8-Bit Code Table, and the DOS U.S. ASCII
Character Set.
Appendix D, “Broadcast and Protocol Messages”, presents information and instruction for the
host programmer when working with LDS Plus broadcast and protocol messages.
Appendix E, “Key Maps”, describe the LDS specific keypresses to use when operating LXE
DOS certified computers.
