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.

Enter Program Mode
**Ability to Enter Program When this option is selected, pro-
Mode After Any Scan gramming can be entered by scann-ing
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 posi-
tion 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 delay Short Same
is ½ second, while the LONG SAME SYMBOL RE- Symbol Re-Scan
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
Symbol Re-Scan
Identical Symbol Re-Scan Indicator
During the same symbol timeout, the LED’s do not ** Disable Green LED
provide an indication of when the unit is ready to
begin scanning the same symbol again. To program
a LED to flash when thepreset delay is over, configure
the scanner to Green LED Enabled. Enable Green LED
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
re-scan. The default, 1 scan buffer only compares
new scanned data against the last bar code scanned.
2 scan buffers allow the scanner to test the last
2 bar codes scanned for same symbol re-scan **Enable 1 Scan Buffer
purposes.
