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...

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.

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 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...

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.

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-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.
