Frequently Asked Questions - MS140 Unitech

How do I connect the MS140-3 keyboard wedge reader to my computer?

Turn off the computer, unplug the keyboard, plug the reader into the keyboard port, then plug the keyboard into the reader. Turn on the computer; a long beep indicates successful power-up.

How do I enter setup mode for the keyboard wedge reader?

You can swipe the 'Keyboard Wedge Setup Label' barcode, or press both left and right SHIFT keys within the first 20 keystrokes after power-up (if device ID is PC/AT). If you have the manual, swipe the 'Enter Setup' label.

What should I do if my computer is not PC/AT?

The default device ID is PC/AT. First set up on a PC/AT machine to select the correct device ID (e.g., device ID '06' for notebook computers). Then connect to your computer.

How do I configure the RS232 interface reader?

Connect the reader to the RS232 port, turn on power. Use a modem communication utility (e.g., HyperTerminal) at 9600 baud, 8 data bits, no parity. Swipe the 'RS232 Interface Setup Label' to enter setup mode.

Can I configure multiple scanners with the same settings?

Yes, use the batch setup feature. In setup mode, select the Dump command or swipe the 'Dump Setting' label to get ASCII strings. Generate Code 39 barcode labels from those strings and scan them on other scanners.

What is the Scanner Configuration Manager?

It is a utility program for Windows 95/98 that allows you to define scanner settings and download them to the scanner via the keyboard port. It can be downloaded from www.unitech-adc.com.

How do I change the baud rate of the RS232 reader?

Enter setup mode using the setup label, then select the baud rate option from the menu. The default is 9600. You can choose from 300, 600, 1200, 2400, 4800, 9600, or 19200 bps.

What barcode symbologies does the MS140 support?

It supports popular symbologies including Code 39, UPC/EAN, Interleaved 2 of 5, Standard 2 of 5, Code 128, Codabar, MSI, Code 11, Code 93, and more.

How do I reset the reader to factory defaults?

You can reset by scanning a specific reset barcode if available, or by reconfiguring each parameter manually. The manual does not provide a single reset label; contact Unitech support for assistance.

What should I do if the reader does not beep after power-up?

Check connections: ensure the reader is properly plugged in. For wedge models, verify the keyboard is plugged into the reader. If no beep, try a different computer port or contact support.

USER MANUAL MS140 Unitech

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.

The default baud rate of the reader is set to 9600, no parity, and 8 data bits.

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:

MS140 SETUP MENU

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.
