Overview
There are two models of the MS140 decoded slot reader available:
• The MS140-3 keyboard wedge slot reader which supports PC/AT, XT,
notebooks and Macintosh computers
• The MS140-2 RS232 interface slot reader that supports computers with
RS232 serial port.
Both of these readers support the most popular bar code symbologies, like
Code 39, UPC/EAN, Interleaved 2 of 5, Standard 2 of 5, Code 128, Codabar,
MSI, Code 11, Code 93, etc.
MS140-3 Keyboard Wedge
Setup of the keyboard wedge reader can be done in three different ways:
• Via computer keyboard of a desktop PC.
Or
• By Scanner Configuration Manager Software to configure the scanner
setting through the keyboard port.
Or
• By using the custom labels (batch setup).
Installation:
The picture below illustrates how to connect the reader to your computer.
Follow these procedures for installation:
1. Turn off computer power.
2. Unplug keyboard from computer. Plug the reader into computer’s
keyboard port and the keyboard into the reader.
3. Turn on power. One long beep from the reader indicates successful
power-up.

The default device ID of the reader is set to PC/AT. If your computer is not a
PC/AT, please perform the setup on a PC/AT machine first in order to select a
correct device ID. The device ID “06” (Keyboardless) is for notebook
computers.

Keyboard Wedge Setup
The reader’s behavior can be changed via a setup routine in the reader. Setup
can be performed on a PC/AT computer with any text editor program, such as
Notepad, WordPad, etc. After the text editor program is running, there are
three different ways to enter setup:
• Swipe the “Keyboard Wedge Setup Label” bar code located on the cover
page of this manual.
Or
• Press the left and right SHIFT keys simultaneously within the first 20
keystrokes after computer power up. (This will apply when the reader
has device ID set to PC/AT interface only. Swipe the “Enter Setup”
label if you have this manual handy.)
Or
• Use custom labels (batch setup).
When the reader enters the setup mode, a selection menu will be displayed on
the screen. Please refer to the MS140 Setup Manual Section.
MS140-2 RS232 Wedge
Setup of the RS232 wedge reader can be done in two different ways:
• Through a modem communication utility (such as HyperTerminal).
Or
• Via custom labels (batch setup).
Installation:
The picture below shows how to connect the reader to your computer. Use the
following procedures for installation:
1. Turn off computer power.
2. Plug the reader into the computer’s RS232 port.
3. Turn on power. One long beep from the reader indicates successful
power-up.

RS232 Interface Setup
The reader’s behavior can be changed through a setup routine in the reader.
Setup can be performed (at 9600 baud rate, 8bits and no parity) with any
modem communication utility, such as Windows’ HyperTerminal. To enter
Setup mode, start the Communication utility on the PC and swipe “RS232
Interface Setup Label” bar code label located on the back page of this manual.
On entering the Setup mode, a selection menu will be displayed on the screen
as follow:

Use numeric keys on the top of alphabetic keys for digit input.
0-Device 1-Scanner 2-Barcode 3-MSR 4-Others 5-RS232 6-Default 7-dump
8-Exit
Select==> _
Follow the prompts and make your selections accordingly. The setup
procedure is that simple. (Use Ctrl_R in lieu of the shift key in a string input
procedure. This method allows the user to input ASCII characters into a
string.)
Batch Setup
If more than one scanner needs to be configured, you can duplicate the settings
of the Master Scanner to the others. This is done by producing a set of custom
setup labels (derived from the master scanner) and then scanning these labels
to configure the other scanners. Selecting the Dump command in setup mode
or swiping the “Dump Setting” label below will dump the settings of the
reader to the screen as one or several ASCII string(s). Use any barcode
printing software, select Code 39 symbology, and use the output string(s) to
generate barcode labels. You can then scan these batch setup labels to
duplicate the settings.

Scanner Configuration Manager
Scanner Configuration Manager is a utility program to configure scanner
settings on a computer using the Windows 95/98 operating system. Use the
program to define the settings and then download the parameters to the
scanner. Download the program from our web site at www.unitech-adc.com.
