4. Turn the terminal/computer power back on. The scanner will beep twice.
5. Verify the scanner operation by scanning a bar code from the back cover of
this manual. The scanner will beep once.
The scanner is now connected and ready to communicate with your terminal/
PC. You must program the scanner for your interface before bar code data can
be transmitted to your terminal/PC. If you are using the scanner as a keyboard
wedge, turn to page 2-1. If the scanner is connected via a serial port, turn to
page 2-9. If this is a wand emulation application, turn to page 2-16, and for a
non decoded output connection, turn to page 6-2.

Parity Even
Data Format 7 data bits, parity bit, 1 stop bit (8 bit data)
RS-232 Interface
In Wand Emulation mode, the scanner decodes the bar code then sends data in
the same format as a wand scanner. The Same Code format transmits UPC,
EAN, Code 128 and Interleaved 2 of 5 bar codes without any changes, but con-
verts all other symbologies to Code 39.
The following Wand Emulation bar code sets the interface to Wand Emulation
mode and translates bar code data as Code 39 symbology. It also programs
the Transmission Rate to 25 inches per second, and Output Polarity to black
high.

Trigger Mode
Manual/Serial Trigger: You can activate the scanner either by pressing the
trigger, or using a serial trigger command (see "Trigger Commands" on page 12-
4). When in manual trigger mode, the scanner scans until a bar code is read, or
until the trigger is released.
When in serial mode, the scanner scans until a bar code has been read or until
the deactivate command is sent. In serial mode, the scanner can also be set to
turn itself off after a specified time has elapsed (see Serial Trigger Time Out,
which follows). Default for NCR RealScan 7837 High-Performance Scanner.
Manual/Serial Trigger
Serial Trigger Time Out: Use this selection to set a time out (in quarter sec-
onds) of the scanner’s trigger when using serial commands to trigger the scan-
ner. Once the scanner has timed out, it must be triggered again either serially
(see "Manual/Serial Trigger: You can activate the scanner either by pressing the
trigger, or using a serial trigger command (see "Trigger Commands" on
page 12-4). When in manual trigger mode, the scanner scans until a bar code is
3-4
Manual Trigger, Low Power: The scanner “sleeps,” using only 30 milliamps,
until the trigger is pulled. When the trigger is pulled, the scanner wakes up and
operates at reduced power until there is no triggering for the time set with the
Low Power Time Out bar code. There is a short delay in operation when the
scanner is first triggered, but there is no delay when operating in low power
mode.
Note: Manual Trigger, Low Power cannot be used with keyboard wedge appli-
cations.
Low Power Time Out: Scan the Low Power Time Out bar code to change the
time out duration. Then scan the time out duration (from 0-300 seconds) from
the inside back cover, and Save. Default = 2 minutes.
Note: If you make an error while scanning the digits (before scanning Save),
scan Discard on the back cover, scan the Lower Power Time Out bar
code, scan the correct digits, then Save again.

chart, page 4-6.)
Miscellaneous Commands
FB Suppress all occurrences of up to 15 different characters, starting at the cur-
rent cursor position, as the cursor is advanced by other commands. When
the FC command is encountered, the suppress function is terminated. The
cursor is not moved by the FB command. Syntax = FBnnxxyy . .zz where
nn is a count of the number suppress characters in the list and xxyy .. zz is
the list of characters to be suppressed. (xx stands for the hex value for an
ASCII code, see Decimal to Hex to ASCII Conversion chart, page 4-6.)
FC Disable suppress filter and clear all suppressed characters. Syntax = FC.
E4 Replaces up to 15 characters in the data string with user specified charac-
ters. Replacement continues until the E5 command is encountered. Syn-
tax = E4nnxx1xx2yy1yy2...zz1zz2 where nn is the total count of both
characters to be replaced plus replacement characters; xx1 defines charac-
ters to be replaced and xx2 defines replacement characters, continuing
through zz1 and zz2.
E5 Terminates character replacement. Syntax = E5.
FE Compare character in current cursor position to the character “xx.” If char-
acters are equal, increment cursor. If characters are not equal, no format
match. Syntax = FExx (xx stands for the hex value for an ASCII code, see
Decimal to Hex to ASCII Conversion chart, page 4-6.)
EC Check to make sure there is an ASCII number at the current cursor position.
If character is not numeric, format is aborted. Syntax = EC.

Code 39 Append
This function allows the scanner to append the data from several Code 39 bar
codes together before transmitting them to the host computer. When this
function is enabled, the scanner stores those Code 39 bar codes that start with
a space (excluding the start and stop symbols), and does not immediately
transmit the data. The scanner stores the data in the order in which the bar
codes are read, deleting the first space from each. The scanner transmits the
appended data when it reads a Code 39 bar code that starts with a character
other than a space. Default = Off.

The message length selection is used to set the valid reading length of the bar
code. If the data length of the scanned bar code doesn’t match the valid reading
length, the scanner will issue an error beep. You may wish to set the same value
for minimum and maximum length to force the scanner to read fixed length bar
code data. This helps reduce the chances of a misread.
EXAMPLE: Decode only those bar codes with a count of 9-20 characters.
Min. length = 09 Max. length = 20
EXAMPLE: Decode only those bar codes with a count of 15 characters.
Min. length = 15 Max. length = 15
For a value other than the minimum and maximum message length defaults,
scan the bar codes below, then scan the 2-digit value and Save bar codes on the
Programming Chart inside the back cover. Minimum and Maximum
lengths = 1-48.
Note: If you make an error while scanning the digits (before scanning Save),
scan Discard on the back cover, scan the Minimum or Maximum bar
code, scan the correct digits, and Save again.

Procedure
1. Use the cloning cable to connect the two scanners for cloning.
2. Connect the destination scanner to one of the 10 pin modular connectors on
the cloning cable.
3. Connect the source scanner (containing the new or updated software) to the
remaining 10 pin modular connector on the cloning cable.
4. Connect the power supply to the 4 pin mini-DIN connector located on the
cloning cable or the scanner cable.
5. Make sure both units are on, and then scan the “Clone Destination” bar
code with the destination scanner.
6. Scan the Clone Source bar code below with the source scanner. The scan-
ner’s “Good Read” LED begins blinking periodically indicating cloning is in
process.
7. When cloning is complete, the destination scanner will double beep. This
procedure takes approximately two minutes.
8. Disconnect the destination scanner from the cloning cable.
9. To clone another scanner, repeat steps 1 through 8.

The device must be set to an RS-232 interface (see page 1-6). The following
commands can be sent via a PC com port using terminal emulation software.
Conventions
The following conventions are used for menu and query command descriptions:
parameter A label representing the actual value you should send as part of a
command.
Prefix Tag SubTag {Data} [, SubTag {Data}] [; Tag SubTag {Data}] […] Storage
Prefix Three ASCII characters: SYN M CR (ASCII 22,77,13).
Tag A 3 character case-insensitive field that identifies the desired menu
command group. For example, all RS-232 configuration settings
are identified with a Tag of 232.
SubTag A 3 character case-insensitive field that identifies the desired menu
command within the tag group. For example, the SubTag for the
RS-232 baud rate is BDR.
Data The new value for a menu setting, identified by the Tag and Sub-
Tag.
12 - 1
Query Commands
Several special characters can be used to query the device about its settings.
12 - 2
Responses
The device responds to serial commands with one of three responses:
NAK Indicates the command was good, but the Data field entry was out of the
allowable range for this Tag and SubTag combination, e.g., an entry for a
minimum message length of 100 when the field will only accept 2 charac-
ters.
When responding, the device echoes back the command sequence with the
status character inserted directly before each of the punctuation marks (the
period, exclamation point, comma, or semicolon) in the command.
This response indicates that Codabar Coding Enable (CBRENA) has a range of
values from 0 to 1 (off and on).
Example: Example #2: What is the default value for Codabar Coding Enable?
Enter: cbrena^.
Response: CBRENA1[ACK]
This response indicates that the default setting for Codabar Coding Enable
(CBRENA) is 1, or on.
12 - 3
This response indicates that the device’s Codabar Coding Enable (CBRENA) is
set to 1, or on.
Example: Example #4: What are the device’s settings for all Codabar
selections?
Enter: cbr?.
Response: CBRENA1[ACK],
SSX0[ACK],
CK20[ACK],
CCT1[ACK],
MIN2[ACK],
MAX60[ACK],
DFT[ACK].
This response indicates that the device’s Codabar Coding Enable (CBRENA) is
set to 1, or on;
the Start/Stop Character (SSX) is set to 0, or Don’t Transmit;
the Check Character (CK2) is set to 0, or Not Required;
concatenation (CCT) is set to 1, or Enabled;
the Minimum Message Length (MIN) is 2 characters;
the Maximum Message Length (MAX) is 60 characters;
and the Default setting (DFT) has no value.
Trigger Commands
You can activate and deactivate the scanner with serial trigger commands.
First, the scanner must be put in Manual/Serial Trigger Mode either by scanning
the Manual/Serial Trigger Mode bar code (page 3-4), or by sending the Manual/
Serial Menu Command (page 12-8). Once the scanner is in serial trigger mode,
the trigger is activated and deactivated by sending the following commands:
Activate: SYN T CR
Deactivate: SYN U CR
The scanner scans until a bar code has been read, until the deactivate com-
mand is sent, or until the serial time out has been reached (see "Serial Trigger
Time Out" on page 3-5 for a description, and the serial command on page 12-
8).

Maintenance
The NCR RealScan 7837 High-Performance Scanner provides reliable and effi-
cient operation with a minimum of care. Although specific maintenance is not
required, the following periodic checks ensure dependable scanner operation:
! Caution:
Do not submerge the scanner in water. The scanner’s housing is not
water-tight.
Do not use abrasive wipers or tissues on the scanner’s window -
abrasive wipers may scratch the window.
Never use solvents (alcohol or acetone) on the housing or
window - solvents may damage the finish or the window.

Troubleshooting
The scanner automatically performs self-tests whenever you turn it on. If your
scanner is not functioning properly, review the following Troubleshooting Guide
to try to isolate the problem.
Is the power on? Is the red illumination beam on?

If the scanner isn’t reading symbols well, check that the symbols:
1. Aren’t smeared, rough, scratched, or exhibiting voids.
2. Aren’t coated with frost or water droplets on the surface.
3. Are enabled in the scanner or in the decoder to which the scanner connects.
Is the bar code displayed but not entered?
The bar code is displayed on the host device correctly, but you still have to
press a key to enter it (the Enter/Return key or the Tab key, for example).
You need to program a suffix. Programming a suffix enables the scanner to out-
put the bar code data plus the key you need (such as “CR”) to enter the data
into your application. Refer to "Prefix/Suffix Overview" on page 4-1 for further
information.
Does the scanner read the bar code incorrectly?
If the scanner reads a bar code, but the data is not displayed correctly on the
host screen:
1. The scanner may not be programmed for the appropriate terminal interface.
For example, you scan “12345” and the host displays “@es%.”
Reprogram the scanner with the correct Plug and Play or Terminal selection
bar code. See Chapter 1 and Chapter 2.
2. The scanner may not be programmed to output your bar code data properly.
For example, you scan “12345” and the host displays “A12345B.”
If you aren’t sure what programming options have been set in the scanner, or if
you want the factory default settings restored, scan "Factory Default
Settings" on page 11-1.
