Keyboard Style
This programs keyboard styles, such as Caps Lock and Shift Lock.  If you have used Keyboard Conversion settings, they will 
override any of the following Keyboard Style settings.  Default = Regular.
Regular is used when you normally have the Caps Lock key off.
Caps Lock is used when you normally have the Caps Lock key on.

Shift Lock is used when you normally have the Shift Lock key on (not common to U.S. keyboards).
Automatic Caps Lock is used if you change the Caps Lock key on and off.   The software tracks and reflects if you have Caps 
Lock on or off . This selection can only be used with systems that have an LED that notes the Caps Lock status (AT keyboards).
Autocaps via NumLock bar code should be scanned in countries (e.g., Germany, France) where the Caps Lock key cannot be 
used to toggle Caps Lock.  The NumLock option works similarly to the regular Autocaps, but uses the NumLock key to retrieve 
the current state of the Caps Lock.
Emulate External Keyboard should be scanned if you do not have an external keyboard (IBM AT or equivalent).  
Note: After scanning the Emulate External Keyboard bar code, you must power cycle your computer.
Keyboard Conversion
Alphabetic keyboard characters can be forced to be all upper case or all lowercase.  So if you have the following bar code: 
“abc569GK,” you can make the output “ABC569GK” by scanning Convert All Characters to Upper Case, or to “abc569gk” by 
scanning Convert All Characters to Lower Case.  
These settings override Keyboard Style selections.  
Note: If your interface is a keyboard wedge, first scan the menu code for Automatic Caps Lock (page 2-16).  Otherwise, your 
output may not be as expected.  
Default = Keyboard Conversion Off.

Control Character Output
This selection sends a text string instead of a control character.  For example, when the control character for a carriage return is 
expected, the output would display [CR] instead of the ASCII code of 0D.  Refer to ASCII Conversion Chart (Code Page 
1252)on page A-3.  Only codes 00 through 1F are converted (the first column of the chart).  Default = Off.
Note: Control + X (Control + ASCII) Mode overrides this mode.  
Keyboard Modifiers
This modifies special keyboard features, such as CTRL+ ASCII codes and Turbo Mode.
Control + X (Control + ASCII) Mode On:The scanner sends key combinations for ASCII control characters for values 00-1F.  
Windows is the preferred mode.  All keyboard country codes are supported.  DOS mode is a legacy mode, and it does not sup-
port all keyboard country codes.  New users should use the Windows mode.  Refer to Keyboard Function Relationships, page 
10-1 for CTRL+ X Values. 
Windows Mode Prefix/Suffix Off:  The scanner sends key combinations for ASCII control characters for values 00-1F, but it 
does not translate prefix or suffix information.
 Default = Control + X Mode Off.

Tu r b o  M o d e :The scanner sends characters to a terminal faster.  If the terminal drops characters, do not use Turbo Mode.   
Default = Off.
Numeric Keypad Mode:Sends numeric characters as if entered from a numeric keypad.  Default = Off.
Automatic Direct Connect Mode:This selection can be used if you have an IBM AT style terminal and the system is dropping 
characters.  Default = Off.
RS232 Modifiers
RS232 Baud Rate
Baud Rate sends the data from the scanner to the terminal at the specified rate.  The host terminal must be set for the 
same baud rate as the scanner.  Default = 115,200.

RS232 Word Length: Data Bits, Stop Bits, and Parity
Data Bits sets the word length at 7 or 8 bits of data per character.  If an application requires only ASCII Hex characters 0 
through 7F decimal (text, digits, and punctuation), select 7 data bits.  For applications that require use of the full ASCII set, 
select 8 data bits per character.  Default = 8.
Stop Bits sets the stop bits at 1 or 2.  Default = 1.
Parity provides a means of checking character bit patterns for validity.
Default = None.

RS232 Receiver Time-Out
The unit stays awake to receive data until the RS232 Receiver Time-Out expires.  A manual or serial trigger resets the time-
out.  When an RS232 receiver is sleeping, a character may be sent to wake up the receiver and reset the time-out.  A trans-
action on the CTS line will also wake up the receiver.  The receiver takes 300 milliseconds to completely come up.  Change 
the RS232 receiver time-out by scanning the bar code below, then scanning digits  from the inside back cover of this man-
ual, then scanning Save. The range is 0 to 300 seconds.   Default = 0 seconds (no time-out - always on).

RS232 Handshaking
RS232 Handshaking allows control of data transmission from the scanner using software commands from the host device.    
When RTS/CTS is turned Off, no data flow control is used.  
Flow Control, No Timeout:  The scanner asserts RTS when it has data to send, and will wait indefinitely for CTS to be 
asserted by the host.
Two-Direction Flow Control:  The scanner asserts RTS when it is OK for the host to transmit.  The host asserts CTS 
when it is OK for the device to transmit.
Flow Control with Timeout:  The scanner asserts RTS when it has data to send and waits for a delay (see RS232 
Timeout on page 2-21) for CTS to be asserted by the host.  If the delay time expires and CTS is not asserted, the device 
transmit buffer is cleared and scanning may resume.  Default = RTS/CTS Off.
RS232 Timeout
When using Flow Control with Timeout, you must program the length of the delay you want to wait for CTS from the host.  
Set the length (in milliseconds) for a timeout by scanning the bar code below, then setting the timeout (from 1-5100 millisec-
onds) by scanning digits from the inside back cover, then scanning Save. 
XON/XOFF
Standard ASCII control characters can be used to tell the scanner to start sending data (XON/XOFF On) or to stop sending 
data (XON/XOFF Off).  When the host sends the XOFF character (DC3, hex 13) to the scanner, data transmission stops.  
To resume transmission, the host sends the XON character (DC1, hex 11).  Data transmission continues where it left off 
when XOFF was sent.  Default = XON/XOFF Off.

ACK/NAK
After transmitting data, the scanner waits for an ACK character (hex 06) or a NAK character (hex 15) response from the 
host. If ACK is received, the communications cycle is completed and the scanner looks for more bar codes.  If NAK is 
received, the last set of bar code data is retransmitted and the scanner waits for ACK/NAK again.  Turn on the ACK/NAK 
protocol by scanning the ACK/NAK On bar code below.  To turn off the protocol, scan ACK/NAK Off.  Default = ACK/NAK 
Off.
Scanner to Bioptic Communication
The following settings are used to set up communication between Honeywell scanners and bioptic scanners.  
Note: The scanner’s baud rate must be set to 38400 and the RS232 timeout must be set to 3000 in order to communicate with 
a bioptic scanner.  See  RS232 Modifiers on page 2-18, and RS232 Timeouton page 2-21 for further information.
Scanner-Bioptic Packet Mode
Packet Mode On must be scanned to set the scanner’s format so it is compatible with a bioptic scanner.  Default = Packet 
Mode Off.
Scanner-Bioptic ACK/NAK Mode
Bioptic ACK/NAK On must be scanned so the scanner will wait for an ACK or NAK from a bioptic scanner after each 
packet is sent.  The Scanner-Bioptic ACK/NAK Timeout (below) controls how long the scanner will wait for a response.  
Default = Bioptic ACK/NAK Off.
 * XON/XOFF Off
ACK/NAK On
 * ACK/NAK Off
* Packet Mode Off 
Packet Mode On 
* Bioptic ACK/NAK Off

Scanner-Bioptic ACK/NAK Timeout
This allows you to set the length (in milliseconds) for a timeout for a bioptic scanner’s ACK/NAK response.  Scan the bar 
code below, then set the timeout (from 1-30,000 milliseconds) by scanning digits from the inside back cover, then scanning 
Save.   Default = 5100.
