Honeywell 1900gsr 2 User Manual

							Xenon/Granit User Guide31 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 soft-
ware 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 key-
boards).
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 Num-
Lock 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 key-
board (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 31). 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 342. 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 key-
board country codes are supported. DOS mode is a legacy mode, and it does not 
support all keyboard country codes. New users should use the Windows mode. 
Refer to ASCII Conversion Chart (Code Page 1252), page 342 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 infor-
mation.
Default = Control + X Mode Off.
Turbo Mode: 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.

style terminal and the system is dropping characters. Default = Off.

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 punctua-
tion), 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 transaction 
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 Programming Chart, beginning on page 
353, then scanning Save. The range is 0 to 300 seconds. Default = 0 seconds (no 
time-out - always on).

RS232 Handshake
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 37) 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 time-
out by scanning the bar code below, then setting the timeout (from 1-5100 milli-
seconds) by scanning digits from the Programming Chart, beginning on page 353, 
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 scan-
ners 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 
34, and RS232 Timeout on page 37 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.
Scanner-Bioptic ACK/NAK Timeout
This allows you to set the length (in milliseconds) for a timeout for a bioptic scan-
ner’s ACK/NAK response. Scan the bar code below, then set the timeout (from 1-
30,000 milliseconds) by scanning digits from the Programming Chart, beginning 
on page 353, then scanning Save. Default = 5100.
