Reading Techniques
The scanner has a view finder that projects a bright red aiming beam that corre-
sponds to the scanner’s horizontal field of view.  The aiming beam should be 
centered horizontally over the bar code and must highlight all the vertical bars of 
the bar code.  It will not read if the aiming beam is in any other direction.
The aiming beam is smaller when the scanner is closer to the code and larger 
when it is farther from the code.  Symbologies with smaller bars or elements (mil 
size) should be read closer to the unit.  Symbologies with larger bars or ele-
ments (mil size) should be read farther from the unit.   To read single or multiple 
symbols (on a page or on an object), hold the scanner at an appropriate dis-
tance from the target, pull the trigger, and center the aiming beam on the sym-
bol.  If the code being scanned is highly reflective (e.g., laminated), it may be 
necessary to tilt the code up 15° to 18° to prevent unwanted reflection.
Menu Bar Code Security Settings
Honeywell scanners are programmed by scanning menu bar codes or by send-
ing serial commands to the scanner.  If you want to restrict the ability to scan 
menu codes, you can use the Menu Bar Code Security settings.  Please contact 
the nearest technical support office (see Limited Warranty on page 12-1) for fur-
ther information.
Setting Custom Defaults
You have the ability to create a set of menu commands as your own, custom 
defaults.  To do so, scan the Set Custom Defaults bar code below before each 
menu command or sequence you want saved.  If your command requires scan-
ning numeric codes from the back cover, then a Save code, that entire 
sequence will be saved to your custom defaults.  Scan the Set Custom 
Defaults code again before the next command you want saved to your custom 
defaults.  
Good Read Bad Read 
						

							1 - 6
When you have entered all the commands you want to save for your custom 
defaults, scan the Save Custom Defaults bar code.
You may have a series of custom settings and want to correct a single setting.  
To do so, just scan the new setting to overwrite the old one.  For example, if you 
had previously saved the setting for Beeper Volume at Low to your custom 
defaults, and decide you want the beeper volume set to High, just scan the Set 
Custom Defaults bar code, then scan the Beeper Volume High menu code, 
and then Save Custom Defaults.  The rest of the custom defaults will remain, 
but the beeper volume setting will be updated.
Resetting the Custom Defaults
If you want the custom default settings restored to your scanner, scan the Acti-
vate Custom Defaults bar code below.  This resets the scanner to the custom 
default settings.  If there are no custom defaults, it will reset the scanner to the 
factory default settings.  Any settings that have not been specified through the 
custom defaults will be defaulted to the factory default settings.

Programming the Interface
Introduction
This chapter describes how to program your system for the desired interface.
Programming the Interface - Plug and Play
Plug and Play bar codes provide instant scanner set up for commonly used 
interfaces.
Note: After you scan one of the codes, power cycle the host terminal to have 
the interface in effect.
Keyboard Wedge
If you want your system programmed for an IBM PC AT and compatibles 
keyboard wedge interface with a USA keyboard, scan the bar code below.  
Keyboard wedge is the default interface.
Note: The following bar code also programs a carriage return (CR) suffix.
IBM PS2 Keyboard
The following bar code programs you scanner for an IBM PS2 keyboard 
wedge interface with a USA keyboard.
Note: The following bar code also programs a carriage return (CR) suffix.
RS232 Serial Port
The RS232 Interface bar code is used when connecting to the serial port 
of a PC or terminal.  The following RS232 Interface bar code also pro-
grams a carriage return (CR) and a line feed (LF) suffix, baud rate, and 
data format as indicated below.

USB IBM SurePos
Scan one of the following “Plug and Play” codes to program the scanner for 
an IBM SurePos (USB handheld scanner) or IBM SurePos (USB tabletop 
scanner) interface.
Note: After scanning one of these codes, you must power cycle the cash 
register.
Each bar code above also programs the following suffixes for each symbol-
ogy:
IBM Secondary Interface
On some older IBM cash registers, it may be necessary to disable the sec-
ondary or management interface.   In particular, it has been found neces-
sary on IBM registers using the 4690 V2R4 operating system.  The 
following bar codes are used for this purpose.  Default = Enable Secondary 
Interface.

USB PC or Macintosh Keyboard
Scan one of the following codes to program the scanner for USB PC Key-
board or USB Macintosh Keyboard.  Scanning these codes also adds a CR 
and LF.
USB HID
Scan the following code to program the scanner for USB HID bar code 
scanners.
HID Fallback Mode
If you attempt to set a USB interface for your scanner, but the setup fails on 
the host system, you can program the scanner to fall back to a HID key-
board interface after a set length of time.  For example, if the scanner is 
configured for Serial Emulation Mode, but the host system does not have 
the correct driver, the scanner would fail.  If you set the HID Fallback Mode  
for a set length of time, for example, 5 minutes, the scanner would change 
to a HID keyboard interface after 5 minutes of trying to configure as serial 
emulation.  
A unique beep sequence indicates that this mode has been entered.  While 
in HID Fallback Mode, the scanner will not scan normal bar codes and 
sounds a unique beep sequence that indicates the scanner is in Fallback 
Mode.  Menu codes can still be scanned while in HID Fallback Mode, allow-
ing you to change the scanner’s programming.

Scan the bar code below, then set the length for the HID Fallback (from 0-
60 minutes) by scanning digits from the Programming Chart, then scanning 
Save.   Default = 5 minutes.   
USB Serial Commands
USB Serial Emulation
Scan one of the following codes to program the scanner to emulate a regu-
lar RS232-based COM Port.  If you are using a Microsoft® Windows® PC, 
you will need to download a driver from the Honeywell website 
(www.honeywellaidc.com).  The driver will use the next available COM Port 
number.  Apple® Macintosh computers recognize the scanner as a USB 
CDC class device and automatically uses a class driver. 
Scanning either of these codes also adds a CR and LF.
Note: No extra configuration (e.g., baud rate) is necessary.

ACK/NAK Mode
Communication Timeout
This allows you to set the length (in milliseconds) for a timeout for the host 
ACK/NAK response.  Scan the bar code below, then set the timeout (from 
0-65535 milliseconds) by scanning digits from the Programming Chart, 
then scanning Save.   Default = 2000 ms.
Timeout Retries
This setting limits the number of Communication Timeout retries.  If the 
Timeout Retries is set to 0, the transmission is terminated after the ini-
tial Communication Timeout.  Scan the bar code below, then set the 
number of retries (from 0-255) by scanning digits from the 
Programming Chart, then scanning Save. (5 is the recommended set-
ting.)  Default = 0.

Communication Timeout Beeper
This selection programs the scanner to issue an error beep when a 
communication timeout has occurred.  The error beep sound is pro-
grammed using Number of Beeps – Error (page 3-4).  Default = On. 
NAK Retries
This selection limits the number of NAK retries that can occur in ACK/NAK 
mode.  Scan the bar code below, then set the number of retries (from 0-
255) by scanning digits from the Programming Chart, then scanning Save. 
(5 is the recommended setting.)  Default = 0, or disabled.
Support BEL/CAN in ACK/NAK
This protocol responds to  and  commands when in ACK/
NAK mode.  The scanner sounds an error tone when a  command is 
sent from the host.   terminates the transmission.  Default = BEL/
CAN Off.
