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

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

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.

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.

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 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 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 When this option is chosen, the scanner will

activate and deactivate its RTS signal on each

character that it transmits.

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.

RS-232 Parameter - Scanning Control (DTR Signal)

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

is enabled, the scanner will not transmit unless

an active (+12V) DTR signal is present on the

scanner’s 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

DTR Scan Disable feature, first scan the EN-

ABLE DTR INPUT bar code. To turn off this

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

the first byte transmitted. Second RS232 Byte
