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...

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...

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....

RS485
Scan one of the following “Plug and Play” codes to program the scanner for 
an IBM POS terminal 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:
* Suffixes programmed for Code 128 with IBM 4683 Port 5B, IBM 4683 Port 9B
HHBCR-1, and IBM 4683 Port 17 Interfaces

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...

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...

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...

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...

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 =...
