Note: These terminal interfaces reflect the current level of firmware. New

interfaces may be added to those listed in Table 1. Contact Customer
Service for an updated list.

1.2 System Hardware Overview (2000/R and 2000/C)

The basic SCANTEAM 2000 system includes connectors that are
compatible with a bar code scanner, a magnetic stripe reader, RS–232D
Aux port, and terminal and PC interface cables. All SCANTEAM 2000
decoder and keyboard interface hardware is mounted on a single, printed
circuit board. The electronics is housed in a rugged, plastic cabinet that
can be securely attached to the terminal.

1.2.1 Connection Options

The SCANTEAM 2000 Series has two connection schemes that can be
selected depending upon the requirements of the bar code application. In
the first connection scheme, illustrated in Figure 1.1, the decoder is used as
a keyboard wedge.

Figure 1.1 Keyboard Wedge Connection

SCANTEAM 2000 Hardware/Software Overview

In this configuration the SCANTEAM 2000 provides a transparent
interface between the keyboard and the keyboard input port of the terminal
or PC. Output data format from the decoder unit is programmed using a
bar code programming menu. When installed, bar code symbols decoded
by the SCANTEAM 2000 are translated to corresponding keyboard
keycodes and sent to the keyboard input port of the terminal or PC. Thus,
bar code data appears as if it had been keyed in at the keyboard.

Figure 1.2 illustrates the second connection scheme. The SCANTEAM
2000 is configured for direct connection.

Figure 1.2 Direct Connection

With the addition of optional field installable IC’s, the SCANTEAM 2000
supports IBM 4683 Port 17/5B/9B and RS–232 (“serial wedge”)
input/output capability.

SCANTEAM 2000 Hardware/Software Overview

1–3

1.2.2 Serial Wedge Capability ( 2000/ C Only)

The SCANTEAM 2000/C may also be used as a serial wedge. In this
configuration the SCANTEAM 2000/C is hooked to both a terminal and a
host computer. The decoded information is displayed on the terminal and
gathered and disseminated on the host. For example, if, in a commercial
environment, bar code readers are used to gather production data, an
assembler may complete a job and indicate that the job is finished by
scanning the information using a bar code reader. The SCANTEAM
2000/C then decodes the information and sends it to a terminal on a
supervisor’s desk, and simultaneously, sends it to a host computer where
the job is registered as done, inventory counts are changed, and the master
schedule is updated.

The serial wedge capabilities are compatible with RS–232 levels, offering
programmable communication to the host, to the terminal, or to both.
When idle, the SCANTEAM 2000/C enables the loop through of both
T erminal TX, RX, and Host TX, RX. All lines are monitored before data
is transmitted to make dure that the data being sent through the 2000 will
not be corrupted. The 2000 does not support RTS/CTS handshaking and is
not capable of processing and receiving data.

The programmable serial wedge parameters are baud rate (300–19200 bps),
parity (odd, even, mark/none, space), data bits (7, 8), and output modes (T o
Host and T erminal, To Host, or To Terminal).

1.2.3 Cloning

The SCANTEAM 2000 Series wedge includes a cloning capability which
provides a way to re–program installed wedges from a “source” wedge.
This capability eliminates the need to use a PC for each download. You
would use the Flash E Prom software program at a terminal to download
the information to the SCANTEAM 2000 “source” wedge. The Flash E
Prom is a programmable/erasable ROM (Read Only Memory) which
enables you to download new interfaces and upgrades without opening the
decoder. The “source” wedge would then be used to program the
“destination” wedges.

Note: Some terminals and power supplies support only one wedge.

Note: If you are using the cloning feature, make sure that the “source” wedge

is at the latest firmware revision level.

If you are going to use the cloning capability, make sure that the “source”
wedge is at the latest revision level of firmware. When you use the cloning
capability, you must make sure that the parity and baud rate of the
“destination” and the “source” are the same.

SCANTEAM 2000 Hardware/Software Overview

1–5

After you check the parity, baud rate, and RS–232D chip compatibility, you
would scan the bar code below. The “source” wedge sends a Syn Del
Return message to the “destination” putting it in cloning mode.

Cloning Bar Code

Caution: DO NOT scan this bar code unless you are going to clone a

wedge. If you do, you will lock up your wedge and will have to
turn the power off and back on.

The “source” then sends 512 64 byte blocks of information followed by a
block check character. This takes approximately 20 seconds. When the
information has been downloaded to the “source,” ROM and RAM tests
are performed. If the cloning is successful in the 2000R, one beep will
sound. If the cloning is successful in the 2000C, two beeps will sound. If
the 2000 fails the ROM and/or RAM tests, you will hear three beeps (five
beeps if both tests fail).

The following figure illustrates the pin layout for the cloning cable.

1.2.4 Interface Cables/Connectors

The SCANTEAM 2000/R is configured for a particular interface by
connecting the correct interface cable. The unit supports OCR interfaces
with +5V only pull–ups in the host device. Higher voltage pull–ups may
damage the SCANTEAM 2000 output chips.

The SCANTEAM 2000/C is configured by scanning the proper terminal ID
from the Programming Menu and by connecting the proper interface cable.

The OCR, OCIA and RS–232D cable connectors on the terminal end vary
in connector type and pinout as determined by your equipment.

1.3 System Software Overview

1.3.1 Programmable Selections

The SCANTEAM 2000 can be programmed to autodiscriminate among the
following bar code symbologies and their variations: CODABAR, Code 3
of 9, UPC, EAN/JAN, Code 2 of 5, Interleaved 2 of 5, Code 93, MSI, Code
128, Matrix 2 of 5, Plessey, and Code 11.

The SCANTEAM 2000/R software is designed to support keyboards
equipped with either data entry or telephone style number pads, and is
capable of emulating keyboard function keys.

The SCANTEAM 2000/C software is configured to support data entry or
CTRL + keyboard configurations. Refer to page 6 of the SCANTEAM
2000 Programming Menu.

In addition to decoding selections, data output formats and auxiliary port
parameters are also menu programmable using the SCANTEAM 2000
scanning device.

1.3.2 Non–Volatile Memory

The SCANTEAM 2000 contains 512 bytes of non–volatile memory which
are used to store operating parameters programmed by means of the bar
code programming menu.

SCANTEAM 2000 Hardware/Software Overview

1–7

An internal power monitor circuit resets the SCANTEAM 2000 hardware
when the nominal +5.0V operating voltage drops below +3.9V. A
software watchdog routine re–initializes the SCANTEAM 2000 if illegal
program execution occurs. A power monitor circuit is included to
re–initialize the SCANTEAM 2000 in the event a temporary power
interruption.

1.3.3 Memory Tests (2000/R ONLY)

When powered–up the SCANTEAM 2000 performs a ROM test and a
RAM test. A test failure causes the SCANTEAM 2000 to issue a single or
double beep sequence, respectively. A test of non–volatile memory
contents also is performed. If the SCANTEAM 2000 fails this test, it
issues a triple beep. Refer to T able 4.1 in Chapter 4, Programming the
Decoder for the beeper sequence and meaning.

1.4 Scanning Devices

The SCANTEAM 2000 is compatible with all Welch Allyn contact and
non–contact bar code scanners, including bar code contact wands, laser
guns, CCDs, and swipe readers. In addition, the product offers a dedicated
port for magnetic stripe scanning applications and supports “triple track”
scanning. Consult your Welch Allyn Sales Coordinator for specific model
numbers of compatible scanners.

2.2 Terminal Interface Cable

A single T erminal Interface Cable (depending upon decoder application) is
supplied with every SCANTEAM 2000 decoder. Interface cable options
and their associated part numbers are listed in Appendix C.

Keyboard Interface cables are custom fabricated for the designated
terminal/keyboard layout. They are properly terminated with all necessary
connector(s) to mate with the user terminals. The user end of T erminal
Interface Cables intended for OCR (SCANTEAM 2000/R),
OCIA(SCANTEAM 2000/R), and RS–232D applications varies in
connector type and pinout as required by your device.

2.3 Interface Port

The SCANTEAM 2000 Interface Port is a 40–pin high density connector
located on the back panel. This connector provides the signals necessary to
connect to and operate with the terminal. The output data format of the
Interface Port must be programmed before the decoder communicates
properly with the terminal.

The Interface Port is programmed using the Data Formatting Editor, the
Bar Code Chart, and Auxiliary Port Data Formatter pages in the
SCANTEAM 2000/R/C Programming Menu. Instructions for their use are
contained in Chapter 4, Programming the Decoder.

2–2

Hardware Description

2.4 Auxiliary Port

2.4.1 Description

The SCANTEAM 2000 Auxiliary port is a 6–pin modular connector on the
rear panel of the decoder. It is only supported if the SCANTEAM 2000 is
equipped with an option chip configured for Aux RS–232D. The function
of this port is to transmit RS–232D data with RTS/CTS handshake and
receive the same according to the protocols outlined in Chapter 4,
Programming the Decoder.

The SCANTEAM 2000/R decoder must receive input data with the
following format: 1 Start, 7or 8 Data, 1 Parity, and 1 Stop Bit. The Aux
port can be programmed to operate at baud rates of 300, 600, 1200, 2400,
4800, 9600, 19200, and 38400 and with mark, space, even, odd, or none
parity. For proper operation the SCANTEAM 2000 must be programmed
for the same baud rate and parity as the connected RS–232D device.

The SCANTEAM 2000/R Aux Port is equipped with a buffer that holds up
to 256 characters. If an incoming message exceeds this length, the decoder
stores the extra characters by overwriting those characters stored at the
beginning of the buffer.

2.4.2 Basic Receive Operation

In the SCANTEAM 2000/R decoder data transfer is initiated when the
RS–232D device sends data. (Refer to Page 4–24 for 2000/C information.)
The SCANTEAM 2000 continues to receive and store data until receipt of
an End of Record Character.

The SCANTEAM 2000 lowers the CTS line and transmits the data to the
POS interface or terminal. Data is framed by the Preamble/Postamble if
preambles or postambles have been programmed. When all data has been
sent to the POS interface or terminal, the SCANTEAM 2000 raises the
CTS line causing the Aux Port to return to ready status. New Aux Port
data is now permitted. Refer to Chapter 4, Programming the Decoder, for
information on the operation of the 2000/C.

Hardware Description

2–3

Aux Port data can be formatted according to the SCANTEAM 2000
terminal program requirements for keyboard interface applications using
the Data Formatter page in the programming menu. Instructions
concerning the formatting are contained in Chapter 4, Programming the
Decoder of this manual.

2.4.3 Transmit Operation

When RS232 Aux transmission is needed. select the terminal selection 00.
Data is sent with preambles and postambles if preambles/postambles are
programmed using valid ASCII characters (00–7F Hex).

2.5 Scanner Ports

The SCANTEAM 2000 features two scanner ports that are compatible with
all Welch Allyn industrial grade digital wand–type scanners, as well as the
Welch Allyn Model 5500 Series and 3000 CCD scanners. Some
non–Welch Allyn scanners may also be supported.

2.6 Magnetic Stripe Triple Track Reader (MSR) Port

The MSR port on the front panel of the SCANTEAM 2000 is dedicated to
the MSR 6900 magnetic stripe reader and is designed to accept undecoded
digital signals. T o process output from the reader, the MSR port must be
programmed through the scanner port using the programming menu. The
SCANTEAM 2000 MSR port cannot be programmed using the magnetic
stripe reader.

Data contained on bank credit cards and travel and entertainment cards
(i.e., American Express, etc.) as defined by ANSI are contained on tracks
1, 2, and/or 3 as shown in T able 2.1. The SCANTEAM 2000 user may
select either track as a source for data: (a) either track 1, 2, or 3; (b) tracks
1, 2, and 3; or (c) any one combination of the eight desired coding.
Specific instructions for programming the MSR port are discussed in
Chapter 4 of this manual and described in the SCANTEAM 2000
Programming Menu.
