Scope of the MS951 Programming Guide

This Manual contains all of the configuration codes for all versions of the
MS951 hand-held bar code scanner products.

Not all hardware versions of the scanner support all of the features universally.
PC Keyboard Wedge units do not use baud rates. Light Pen emulation
scanners should not try to drop UPC/EAN check digits. Some features will
deliver different results based upon the primary interface selected.

Emphasis will be placed on PC Keyboard Wedge and RS-232 applications.
Keyboard Wedge units default to Keyboard Wedge communications. All other
units default to RS-232 parameters.

Programming the Scanner

The scanner is shipped from the factory programmed to a set of default
conditions noted in this guide by an asterisk that appears before the brief
definition. Since each host system is unique, the scanner has to be configured
to match your host system requirements.

1. Connect the scanner to the host system or power source.
(Refer to the Installation and User’s Guide MLPN 2365.)

2. Scan the ENTER/EXIT PROGRAM MODE bar code.
(The unit will beep three times.)

Enter/Exit

Program Mode

* *

3. Scan by positioning the output window within two inches of each code.
(When the first menu selection has been scanned, the laser will stay on
until the ENTER/EXIT PROGRAM MODE code is scanned again. If
no scanning occurs for 30 seconds while the scanner is in program
mode, the unit will beep three times and all changes made will be lost.
If this occurs, return to Step 1.)

4. Upon completing the scanning of the appropriate configuration options,
scan the ENTER/EXIT PROGRAM MODE bar code again. (The new
options will be saved and the scanner is ready for normal operation.)

Note: While in program mode, the scanner will make a “razz” sound when:

! the bar code it is scanning is not a program mode

code type;

! the feature is not currently supported in the firmware;
! the feature is not supported on the scanner’s hardware

configuration.

The sound serves as an audible indication that the scanner will not
support that feature.

RS-232 Parameter - Baud Rate

A baud rate is a unit that measures the speed with which information is
transferred. The baud rate of the scanner must equal the baud rate of the host
device. The available baud rates range from 300 to 38400.

RS-232 Parameter - Parity

Parity is an additional digit that makes the number of bits in the ASCII code
odd or even. The scanner’s parity must match the host’s parity.

**Space Parity Select this option to make the parity bit always 0.

P A 1

Even Parity Select this option to make the additional parity bit either a

0 or 1 to guarantee an even number of bits.

Mark Parity Select this option to make the parity bit always 1.

P A 2

Odd Parity Select this option to make the additional parity bit either a

0 or 1 to guarantee an odd number of bits.

P A 4

RS-232 Parameter - Data Bits

RS-232 serial communication requires ASCII data to 8 Data Bits
be transmitted in either 7 or 8 data bits. In addition,
one parity bit will be transmitted. If necessary, scan the
appropriate bar code that matches your host device’s
requirements.

Generally, if 7 data bits are selected, 2 stop bits are ** 7 Data Bits
transmitted. If 8 data bits are selected, 1 stop bit is
transmitted . Stop bits are actually just an idle trans­mit line. From the scanners perspective, they are only
important if the scanner is receiving more than 1 byte
of information at a time. For most applications, the
scanner is a transmit only device.

during transmission, your host device may require
an RTS/CTS signal. When the RTS/CTS (Request

setting of RTS/CTS is disabled. If necessary, scan

For control of the data transmission process, use ACK/NAK or XON/XOFF
instead of or in addition to the RTS/CTS hardware handshaking option.

Longitudinal Redundancy Check (LRC)

A Longitudinal Redundancy Check (LRC)is an Enable LRC Calc+
error checking character that is calculated across Transmit RS232
a sequence of data characters. It is determined by
eXclusive ORing (XOR) the characters to be
checked, starting with an initial value of 00H.

The result, an "LRC byte" is then transmitted Transmit RS232
following the data stream and used by the receiving
computer to determine if the information was received
correctly. In the scanner's case, XOR is performed

prior to adding parity bits. Start LRC on
