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 Α razz sound
when:
¾the bar code it is scanning is not a program mode code type;
¾the feature is not currently supported in the firmware;
¾the 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.

Enter Program Mode
**Ability to Enter Program When this option is selected, pro-
Mode After Any Scan gramming can be entered by scann-
gin the ENTER/EXIT PROGRAM
MODE bar code after power up or
during normal scanning operation.
Enter Program Mode When this option is selected, the
Only on First Scan scanner will only enter program
mode after power-up. Scan the
ENTER/ EXIT PROGRAM MODE
bar code immediately after the scan-
ner first receives power. This option
prevents the scanner from accident-
ally entering program mode during
normal scanning operation.
Recall Defaults
If during programming of the scanner,
there is a need to return to the original Recall Defaults
factory settings, scan the RECALL
DEFAULTS bar code. Any settings
selected during that session or a
previous session will be lost.

Laser Activation Range
Short Range Activation When this option is selected, the IR sensor
Out of the Stand is guaranteed to be activated when the posi-
tion of the scanning window three inches
from the object.
Short Range Activation When this option is selected, the IR sensor
In the Stand is guaranteed to be activated when an object
is presented three inches from the scanning
window.
**Long Range Activation When this option is selected, the IR sensor
Out of the Stand is guaranteed to be activated when the
position of the scanning window is eight
inches from the object.
**Long Range Activation When this option is selected, the IR sensor
In the Stand is guaranteed to be activated when an object
is presented eight inches from the scanning
window.
Laser Operation
** Normal Scan This option is the default setting. When the laser is
activated by the IR sensor, the laser beam emits from
the output window and displays a constant, horizontal
line until a bar code is sensed or until the scanner
timeout elapses.
Pulsing Scan When the laser is activated by the IR sensor, the laser
beam emits from the output window and displays a
horizontal line that pulses until a bar code is sensed or
until the scanner timeout elapses.
Custom Scan This option is available for special applications.
Do not scan the CUSTOM SCAN bar code unless
instructed by a Metrologic representative.

Same Symbol Re-Scan
The scanner is programmed with a same symbol timeout.
For SHORT SAME SYMBOL RE-SCAN, the time Symbol Re-Scan
delay is 2second, while the LONG SAME SYMBOL
RE- SCAN delay is 1 second. These numbers represent
how much time that a bar code must be out of the scan
field before that bar code can be scanned again. ** Long Same

Identical Symbol Re-Scan Indicator
During the same symbol timeout, the LEDs does ** Disable Green LED

the scanner to Green LED Enabled.

1 vs. 2 Scan Buffers
This feature controls the number of bar codes Enable 2 Scan Buffers
considered for the purposes of the same symbol

new scanned data against the last bar code scanned.
2 scan buffers allow the scanner to test the last

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 scanners parity must match the hosts parity.
**Space Parity Select this option to make the parity bit always 0.
PA1
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.
PA2
Odd Parity Select this option to make the additional parity bit either
a 0 or 1 to guarantee an odd number of bits.
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 devices
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 trans-
mit 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.

RS-232 Parameter - Hardware Handshaking
To prevent scanned information from being lost Enable RTS/CTS
during transmission, your host device may require
an RTS/CTS signal. When the RTS/CTS (Request
To Send/Clear To Send) is enabled, the scanner
will output an RTS signal and wait for a CTS ** Disable RTS/CTS
signal before any data is transmitted. The default
setting of RTS/CTS is disabled. If necessary, scan
the ENABLE RTS/CTS bar code.
** Character RTS/CTS
activate and .
Message RTS/CTS When this option is chosen, the scanner will
activate and deactivate its RTS signal on each
message that it transmits. This mode should
normally be enabled for Sanyo registers.
RS-232 Parameter - Software Handshaking
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.
Enable ACK/NAK When this option is enabled, the scanner will not
scan again unless an ACK (ASCII 06H) is
received after transmission of a bar code. If an
NAK (ASCII 15H) is received, the scanner will
** Disable ACK/NAK retransmit the bar code.
Enable XON/XOFF When this option is enabled, the scanner will
stop transmission whenever an XOFF (ASCII
13H) is received. Transmission will resume after
an XON (ASCII 11H) is received.

When the DTR (Data Terminal Ready) input Enable DTR Input

scanners DTR input pin. The scanner can be
disabled by making DTR inactive (-12V) at ** Disable DTR Input
the DTR input pin.
The DTR Scan Disable feature will prevent
any scanning when the Enable DTR input Enable DTR Scan Disable
feature is chosen. Before enabling the Enable

feature, scan the Recall Defaults bar code.

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.
**Disable LRC Calc+
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
First RS232 Byte
When the LRC is enabled, the scanner defaults to
starting the LRC on the second byte of information
transmitted. Optionally, the calculation can start on **Start LRC on
