LDS Plus TE Overview
LDS Plus is LXE’s DOS based LDS Terminal Emulator (TE) and allows an LDS host application
to communicate with an LXE DOS terminal.

messages, please refer to Chapter 2, “Getting Started”.

The LXE DOS terminal accepts data entry from the keyboard, barcode scanner and the auxiliary
(RS-232) input port. Data entry is possible only while the DOS terminal displays the compose
buffer.
(RS-232) input port. Data entry is possible only while the DOS terminal displays the compose
buffer.
Keyboard Data Entry
Once the LDS Plus TE is started, data can be entered with the keyboard. Keyboard data can be
entered into a data field and transmitted to the host; note that keyboard input is always enabled,
but it is subject to field control in forms. You might respond to a prompt sent by the host
application with a keyboard entry, such as a menu listing choices for your next action.

Barcode Data Entry
The LXE DOS computers support an accessory barcode reading device. Keyboard data entries can
be mixed with barcode data entries. Any scanner that decodes the barcode internally and outputs
an RS-232 data stream may be used. Barcode data entry can be enabled by a form header,
commands from the host or through the keyboard. Features of barcode data entry include
AutoAdvance, AutoTransmit, Truncation, Barkey (Scannable function key), Barcode Prefix and
Suffix and Barcode Braces. All these are described in a later chapter.

The serial port parameters may need to be changed (using the LDS Plus Configuration Utility) to
match the parameters of the scanner. Refer to the LXE DOS computer’s operator or reference
manual for more information on which COM ports are available for use with a scanner. The
default setting is Comm port 1 for the barcode scanner port and Comm port 2 for the standard
serial (AUX) port.

For example, the vehicle mount DOS computers feature a built in port for barcode input. The
handheld DOS computers feature an integrated laser scanner endcap. Many of the handheld
computers also have an RS-232 endcap that uses the same barcode reader as the vehicle mount
DOS computers.

RS-232 Data Entry
The LXE DOS computer accepts input from an RS-232 device connected to the RS-232 (AUX)
port of the computer. The AutoAdvance, AutoTransmit and Truncate features are also applied to
RS-232 input just as for barcode input. RS-232 input can be enabled by a form header, commands
from the host or by a keyboard keystroke.

from the host or by a keyboard keystroke.
The computer processes data from the RS-232 port the same way it processes barcode or keyed
data. The data is entered at the cursor position, and the data is subject to all of the barcode/RS-232
input menu parameters, such as truncate. The RS-232 Comm port must be activated before
sending data or receiving input.
