**It is best to use the Plug and Play bar codes, beginning on page 1-24 to program these
interfaces, rather than scanning the terminal ID listed in this table.

Scan the appropriate country code below to program the keyboard for your 
country. As a general rule, the following characters are supported, but need 
special care for countries other than the United States:

Keyboard Style
This programs keyboard styles, such as Caps Lock and Shift Lock.  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 (AT and PS/2 
only). This selection can only be used with systems that have an LED which 
notes the Caps Lock status.
Autocaps via NumLock bar code should be scanned in countries (e.g., Ger-
many, France) where the Caps Lock key cannot be used to toggle Caps Lock.  
The NumLock option works similarly to the regular Auotcaps, but uses the Num-
Lock 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 Modifiers
This modifies special keyboard features, such as CTRL+ ASCII codes and 
Turbo Mode.
Control + ASCII Mode On:The image scanner sends key combinations for 
ASCII control characters for values 00-1F.  Refer to Keyboard Function 
Relationships, page 7-1 for CTRL+ ASCII Values.
  Default = Off
Turbo Mode:
The image 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
Control + ASCII Mode On

Connecting the Base with RS-232 Serial Port
1. Turn off power to the terminal/computer.
2. Connect the appropriate interface cable to the base.
Note: For the base to work properly, you must have the correct cable for your 
type of terminal/computer.
3. Plug the serial connector into the serial port on your computer.  Tighten the 
two screws to secure the connector to the port.
4. Plug the power supply barrel connector to the base, and plug the power 
supply into the AC source.
5. Once the base has been fully connected, power up the computer.
All communication parameters between the image scanner and terminal must 
match for correct data transfer through the serial port using RS-232 protocol.  
Scanning the RS-232 interface bar code, programs the image scanner for an 
RS-232 interface at 115,200 baud, parity–none, 8 data bits, 1 stop bit, and adds 
a suffix of a CR LF.

RS-232 Baud Rate
Baud Rate sends the data from the image scanner to the terminal at the speci-
fied rate.  The host terminal must be set for the same baud rate as the image 
scanner.  
Default = 115,200.
RS-232 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 applica-
tion requires only ASCII Hex characters 0 through 7F decimal (text, digits, and 
punctuation), select 7 data bits.  For applications which 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.
RS-232 Handshaking
RS-232 Handshaking allows control of data transmission from the image scan-
ner using software commands from the host device.  CTS/RTS operates in 
mode 2.  When this feature is turned 
Off, no data flow control is used.  When 
Data Flow Control is turned On, the host device suspends transmission by 
sending the XOFF character (DC3, hex 13) to the image scanner.  To resume

transmission, the host sends the XON character (DC1, hex 11).  Data transmis-
sion continues where it left off when XOFF was sent.  Default = RTS/CTS, XON/
XOFF and ACK/NAK Off.
Host ACK Selection
Some applications require that the host terminal (or server) approve or reject 
incoming bar code data and notify the operator of these actions.  These applica-
tions require that the host maintain control over the response indicators emitted 
from the source image scanner.  Turning the Host ACK selection on, configures 
the cordless system image scanners to respond to commands from the host 
system.
The following criteria must be met for the Host ACK to work correctly:
 The cordless system must be configured for Host Port RS-232 (terminal ID = 
000)  or USB COM Emulation (terminal ID = 130).
 RTS/CTS is defaulted off.  You must enable it if the host system requires it.
 Host ACK must be enabled (page 2-12). 
 System performance degrades when using Host ACK at rates lower than 
9600.
 The host terminal software must be capable of interpreting the bar code data, 
make decisions based on the data content, and send out appropriate escape 
commands to the source image scanner.
Escape commands are addressed to the source image scanner via “Application 
Work Groups.” Once a command is sent, all image scanners in a group respond 
to that command.  Because of this situation, it is recommended that each 
image scanner is assigned to its own group in host ACK mode.
The commands to which the image scanner responds are listed on page 2-13.  
The  is a 1B in hex.  A typical command string is y  x, where “y” is 
the application work group number, “ x” is the escape command, and the 
comma is the terminator
, which is required.

Commands may be strung together to create custom response sequences.  An 
example of a command string is listed below.
0456,
The above example will make an image scanner in application work group zero 
beep low, medium, high.
Once Host ACK is enabled, the system works as follows:
 The image scanner reads a code and sends data to the base/host system.  
No audible or visual indication is emitted until you receive an escape 
command.  The image scanner read illumination goes out upon a successful 
read.
 Image Scanner is suspended until 1) a valid escape string is received from 
the host system (via the base) or 2) the image scanner “times out.”
 Once condition 1 or 2 above has been met, the image scanner is ready to 
scan again, and the process repeats.
Time out is indicated by three rapid beeps at the same pitch.  A time out occurs 
if the source image scanner does not receive a valid escape command in 10 
seconds.  If a time out occurs, the operator should check the host system to 
understand why a response to the image scanner was not received.
