1. Getting Started

The NCR RealScan 7837 Mid-Range Linear Imager replaces

traditional laser bar code scanners with a high speed scanner at

a lower cost. Equipped with a new generation light

intensifier and optical design, the 7837 Mid-Range Scanner has

a high intensity aiming line and captures bar codes from as far

away as 8 inches (20.3 cm). The unique decoding engine

gives the 7837 Mid-Range Scanner exceptionally fast and

accurate scanning capabilities. Since the built-in flash

memory makes the 7837 Mid-Range Scanner

field-upgradeable, the scanner’s programming is always

up-to-date.

About This Manual

This User’s Guide provides installation and programming

instructions for the NCR 7837 Mid-Range Scanner

(7837-0000-9090). Customer support information is also

included.

NCR's scanners are factory programmed for the most common

terminal and communications settings. If you need to change

these settings, programming is accomplished by scanning the

bar codes in this user’s guide.

Getting Started

1-2

The RealScan 7837 Mid-Range Scanner comes with a main

cable equipped with a RJ-45 phone plug, which can provide

multiple host interface connections when combined with a host

adapter cable. Please note that a separated cable adapter is

needed to complete the cable connection for product

installation.

2. Terminal Interfaces

The NCR RealScan 7837 Mid-Range Scanner is easily

configured to work with a variety of interfaces by installing the

desired cable adapter and by programming the selected

terminal interface. After identifying the communication

interface you will use and obtaining the suitable interface

adapter cable, plug the

RJ45 Phone Plug

of the 7837

Mid-Range Scanner main cable into the connector of the

selected interface cable adapter. Please make sure the

connector clicks into place securely.

7837 Mid-Range Main Cable

All scanners have been preset to the “

IBM

PC/AT, PS/2

Keyboard Wedge

” interface. If you need to change the host

interface, please refer to the “Host Interface Selection”

described in Chapter 3 to find your desired interface. The

following paragraphs provide the installation of the most

popular host interfaces.

Keyboard Wedge Interface

The keyboard wedge interface allows data transmission from

the scanner to the host through the existing keyboard port as

traditional keyboard input.

PC/AT, PS/2 Keyboard Wedge

For the keyboard wedge solution, the scanner must work with

the existing keyboard concurrently. If you want to link the

scanner to a computer keyboard port without a PC/AT or PS/2

keyboard, please select “

Emulate External Keyboard.

”

This selection instructs the scanner to perform the power-on

handshaking and routine reply between computer and

keyboard.

 Verify the RS-232 port (COM1 or COM2) available on your

computer system.

 Plug the RJ45 phone plug of the main cable into the RS-232

cable adapter.

 Plug the 9-pin or 25-pin D-sub connector of the cable converter

into the desired serial port on your system.



A

ttach the power outlet plug of the optional AC power adapter to

the side power jack of the D-sub connector.

You will hear the

power-on beep twice to signal that the scanner is ready for bar

code reading. Scan the “RS-232 Serial Interface” bar code to

configure the scanner to perform the RS-232 serial interface

operation.

RS-232 Serial Interface

 Scanning the RS-232 interface bar code above configures the

scanner’s serial parameters to 9600 Baud, 8 data bits, no parity,

and 1 stop bit, no handshaking.

Please note that the RS-232 settings of the host system must

match the scanner’s RS-232 settings.

3. Programming the

Scanner

To configure the RealScan 7837 Mid-Range scanner, use the

programming bar codes in this user’s guide.

Data Editor

Data Editor is an Artificial Intelligence-based expert system

used to format the scanned data before it is transmitted to the

host system. The Data Editor has been embedded in the

scanner. You gain access to desired Data Editor’s functions via

scanning the menu’s bar code.

Data Format Editor

The ultra powerful data editing functions provided by the Data

Editor are controlled by user-defined rules. Through

independent rules, users can easily get the following

functionality:

 General Transmission Control

The available parameters include “Preamble,” “Postamble,”

“Suffix,” “Symbol ID and Data Length Transmission,” and

“Transmission Time Control.”

 Advanced Data Verification

The user can base the specific data format on the desired Bar

Code Symbologies to select “Valid ASCII Domain,” “Valid

Data Length Domain,” and “Matched Data Value” to establish

any desired filtering algorithm. This feature not only provides

an on-scanner data filter without application software

modification, but also reduces the error reading rate and

improves data capture reliability.

 Field Oriented Data Formatter

The Field Oriented Data Formatter allows the user to flexibly

divide scanned data by “Delimiter” or “Length.” When used

with “Added Field” and “Transmission Sequence

Arrangement” features, you can implement “

Insert

,”

“

Delete

,”

“

Replace

,”

“

Re-organize

,” and other data

editing capabilities beyond your imagination.

Bar Code Programming Menu

The bar code commands are specially designed

Proprietary

bar code labels that allow you to set the scanner’s internal

programming parameters. The three main programming bar

code types are referred to as

System Command

,

Family

Code

, and

Option Code

. With the exception of the Option

Code bar codes, which are found in the Appendix of the book,

each programmable family is contained on one page, and each

page includes all of the bar codes needed to program the

scanner. Refer to the flow chart on page 3-4 for further

clarification.

System Command

The System Command is the highest level bar code command

that directs the scanner to perform immediate operations, such

as entering programming mode (

PROGRAM

), exiting

programming mode (

EXIT

), listing system information

(

SYSLIST

), recovering to factory preset configurations

(

M_DEFAULT

), and so on. Please note that all system

commands will take a few seconds to complete the operations.

The user must wait for the completion beeps before scanning

another bar code.

Family Code

The Family Code is scanned to select the user desired

programming family. More than one hundred programming

families have been provided to meet any specific requirements.

Option Code

The Option Codes is a set of bar code commands represented

by “

0–9

,” “

A–F

,” and finishing selection (

FIN

). For most

settings, you must select at least one option code following the

family code selection to set the desired parameter for the

selected programming family.

Programming Procedures

As you scan the bar code command to select the desired

parameters, the information is stored in the scanner’s internal

Flash Memory ASIC or non-volatile memory. If you turn off

the unit, the Flash Memory ASIC or non-volatile memory

retains all programmed settings.

Programming the Scanner

3-3

Program & End

Scan

“PROGRAM”

Scanner enters programming mode,

and inhibits all non-programming functions.

Scan

“END”

Scanner exits programming mode, and stores all

parameters in Flash Memory ASIC or non-volatile memory,

then issues the completion beep (3 short beeps).

Please note that the scanner will take 3-4 seconds to store

parameters in internal Flash Memory ASIC or non-volatile

memory after you scan the “

END

.” Please

do not

turn off

the power before the completion beep. It may destroy all

configured parameters.

System List & Master Default

Scan “

M_DEFAULT

”

Scanner returns all programmable

parameters to factory preset configurations,

then issues the completion beep (

3 short beeps

).

Scan “

SYSLIST

”

Scanner lists the product information and

revision number to host via selected host interface,

then issues the completion beep (

3 short beeps

).
