Extech Data Systems Celebrates 10 Years
Design and Manufacture Battery Operated Portable Printers
Extech Data Systems, the Portable Printing Division of Extech Instruments, started Engineering
development of a new line of portable instrumentation in 1988, just ten years ago. The first
products from this development, a portable battery operated printer and a portable modem were
introduced in 1989. Designed specifically for the Psion Organiser, this initial foray into the world
of mobile computing proved highly successful. The advent of a low cost, battery operated
portable printer allowed innovative individuals and organizations to develop system solutions for
a variety of interesting applications, including:
§ Duty Gear who developed ‘Ticket Writer,’ a self-contained portable computer system,
programmable that generates parking tickets directly from Extech’s integral printer.
§ Precision Systems who introduced PESTWARE a “revolutionary, cost saving
productivity tool designed to reduce paperwork, handwritten work orders and invoices” for
the Pest Control industry. Using an Extech Comms printer, the system prints work orders and
invoices on the job site.
§ Harvest Computer Consulting who designed Farm Handy™ specifically for agricultural
payrolls using compensation based on a piece rate. The system allows for immediate printing
of receipts for employees.
§ Joint Technologies Ltd. who introduced CoinTRAX© Model 50, a portable coin counting
system that provides fast, accurate accounting of coin and token income from various
machines, companies and locations. CoinTRAX© also provides count verification of tagged
bags, totes, coin rolls and over-the-counter receipts.
Introduction of the mini-serial printer increased the potential for our printers, allowing
integration with virtually any RS232 serial device, including portable computers, pen computers,
vending machines and weighing scales.
§ Streetguard™ Inc. who developed Streetguard VVRS, a hand-held pen computer based
parking ticket writing system that allows writing of the ticket directly on the pen computer
screen and then printing out to the Extech Mini Serial Printer.
In 1991, we introduced a built-in magnetic card reader (MCR) option — available to read either
tracks 1 and 2 or tracks 2 and 3. Both tracks are read and decoded simultaneously. Decoded data
was transferred to the host computer, via the serial port, for verification and consolidation into
receipt form. The completed data is then sent back to the printer for receipt printing. Nowadays,
data transfer is possible through the serial port, bi-directional parallel port or the IrDA port. A
unique two-way communication protocol allows for the decoded data from the magnetic card to
be transmitted to the host computer. Again, a number of interesting applications have been
developed, including:
§ Micros’ Hospitality: visit the Fleet Center in Boston for a Celtics or Bruins game and
enjoy the rapid food system made possible by Micros’ pioneering ordering system. Linking a
hand held pen computer system, local radio network system and an Extech printer with builtPage 2
in magnetic card reader allows fans to order directly from their seat. The order is radioed to
the kitchen, filled and delivered right to the seat. Payment by credit card is made,
authorization obtained over the radio network and on to the next fan! The system is so quick,
additional kitchen space was added!
§ Swedish Railway who introduced “the first computerized conductors in the world”
equipped with a hand held computer and an Extech Mini Serial Printer enabling passengers to
purchase their ticket on the train. A magnetic card reader, integrated right into the printer
means the passenger can pay by credit card as well as cash. The magnetic card reader is set to
read tracks 2 and 3 simultaneously, decode the data and transfer it to the hand held computer.
Extech Data Systems — Ten Years On
EXTECH Data Systems nowadays designs and manufactures battery operated, portable printers
for portable and mobile computing applications. Powerful micro-controllers on highly integrated
circuit boards manage all the features supported by the printers. Custom firmware and printer
designs are provided to meet a wide range of application requirements including special graphics,
simultaneous read of dual track magnetic cards, datalogging, etc. The user may choose impact or
thermal print heads. A full range of communication interfaces is available: serial (RS232),
parallel (unidirectional and bi-directional), infrared IrDA or ASK), and magnetic card reader. All
data interfaces are DOS and Windows compatible. Integration with hand-held computers, PDAs,
pen computers and notebook computers is easily accomplished by OEMs and their system
integrators.
The printers may be operated from a battery pack or from an AC power adapter. Battery
operation provides up to 2 hours of continuous print time - more than sufficient for a normal
shift’s work. A fast charge circuit fully charges the battery in 90 minutes. The high impact plastic
housing encloses easily loaded, single or two-ply paper rolls. Connectors are placed for wearing
comfort and to minimize exposure to the elements. Membrane switches with bright LEDs are
easily reached when worn on a belt or placed on a desk. Typical applications include field sales,
field service, meter reading, route accounting, ticket issuance, and more. Recent product
developments include:
§
Series 2000 (updated impact printer range) and Series 2000T (new thermal printer range).
The new products incorporate a larger paper roll, a new IrDA wireless communication
system, an improved battery charging system, large memory and a new body housing with
built-in belt clip
§
Built-in magnetic card reader version especially suitable for field applications where
payment is preferred at the time of service delivery. Mobile point of sale applications
(EPOS) can also benefit from use of this new printer. Integration with wireless systems
makes credit card authorization possible (EFTPOS)

Section 3 ... Battery
Battery Recharging Operation
§
The Extech Printers features an internal fast battery recharge system. This system is
designed to fast charge the battery cartridges in 90 minutes using 120V/9VDC/1.0A
power adapter (PN# 152120). This adapter is designed for North American use. Both
220V (PN# 152320) and 240V (PN# 152340) versions are available for international use.
§
The battery voltage, temperature and maximum charge time are monitored during battery
recharge cycle.
Initiating Fast-Charge
§
The battery Fast-charge is initiated, when the power adapter is applied to the printer.
§
The battery's voltage and temperature are checked by the fast-charge controller before the
start of the fast recharge process.
§
If the battery voltage or the temperature is outside of the fast-charge limits, the charger
defaults to trickle charge at C/64 rate.
§
If the battery voltage and the temperature are valid the yellow <CHARGE> LED is
illuminated and the fast-charge at the 1C rate is initiated. The battery temperature and
voltage limits are as follows:
Ÿ
Temperature:
less then 50C
Ÿ
Voltage:
greater than 2 VDC or less than 7 VDC.
Fast-Charge Termination
§
The controller continues the fast-charge process until any one of the following charge
termination conditions are encountered:
Ÿ
Peak battery pack voltage is detected.
Ÿ
Recharger Timer time-out (90 minutes).
Ÿ
Battery temperature greater then 50C
§
The yellow fast <CHARGE> LED is turned off at the end of the fast charge cycle and a 5
minute Top-off charge cycle is initiated. The Top-off charge cycle insures full battery
charge.
§
Pulsed trickle charge cycle follows the Top-off cycle. The battery is trickle charged at
C/64 rate.

Resident Character Sets (S2000i)
§
There are 3 resident fonts for the 2000i.
CHARACTER NAME
MSP FONT
International character set (Standard)
Hebrew character set
IBM compatible character set
ESC+F+1
ESC+F+2
ESC+F+3
§
The characters are formed using a 5x7 matrix. The first 127 entries in the font table are
ASCII characters. Characters 0 through 31 are ASCII printer control characters, while 32
through 127 are the 96 ASCII alpha numeric upper and lower case characters
§
The alternate (extended) characters for each font type are from 128 through 255
§
The printer defaults to Standard font on initial power up or upon receiving the CANCEL
command (^X,18H,24).
Character Size
§
Four character sizes can be selected through the communication interface, by sending
control characters to the printer
Character Size
Normal
Expanded (Double Wide)
Extended (Double Height)
Large (double wide and double height)
Dot matrix size
5x7
10x7
5x14
10x14
Normal Character
§
The Normal characters are formed using a 5x7 dot matrix. The printer defaults to 5x7
matrix Normal character size upon initial power-up.
Expanded Character
§
Expanded size or double wide characters are formed by using 10x7 dot matrix.
§
Expanded print is selected by sending the EXPAND character command (0E/14) to the
printer, all succeeding characters are printed in Expanded form. Sending the EXPAND
OFF character (0F/15) or Carriage Return resets the Expanded print to normal print.
Extended Character
§
The Extended or double height characters are formed by using a 5x14 dot matrix.
§
Extended Print can be selected through the communication interface by sending the
EXTEND command (1C/28) character. EXTEND (1D/29) or Carriage return resets the
Extended print to normal print.
Large Character
Page 17
§
The Large characters are formed by using a 10x14 dot matrix. Large character print is
selected if both Expanded and Extended print is selected. To reset large print to normal
print, Expanded and Extended prints must be disabled or Carriage return sent to printer.
Dot Addressable Graphics
§
The SERIES 2000i can print special symbols, graphs and characters if operated in the
Dot Addressable Graphics mode.
§
In the Dot Addressable Graphics mode of operation, the printer prints one dot line at a
time. Each horizontal dot line is made out of (1x6) dot cells, and the total number of dot
cells per line is the same as the maximum number of columns on the printer.
§
Each dot in a (1x6) dot cell can be turned ON or OFF by sending specific ASCII
characters.
§
The graphics mode is invoked by sending ASCII characters 'ESC' (1B/27) followed by
'G'. Dot line printing starts upon receiving enough dot cells to complete a dot line, or
ASCII 'CR' (0DH) or ASCII 'LF' (0AH)
§
The graphics mode is terminated by sending ASCII characters 'ESC', followed by 'A'.
Graphic Character Set
§
The graphic character set extends from the character '?'(3FH) to TILDA (7EH). Bits 1
through 6 of the characters received are used to turn ON or OFF the dots in a dot cell.
§
If a bit is set (=1), a dot is enabled, otherwise the dot is disabled.
§
For example for ASCII '?' (3FH or 00111111B), bits 1 through 6 are set. Sending
consecutive '?'s will form a one dot solid line across the paper.
Page 18
Section 6 ... S 2000T Character Sets
Resident Character Sets
§
The Series 2000T has two resident character sets, the standard international and IBM
compatible character sets. For both resident character sets, the lower 128 bit values follow
the ASCII standard. Characters 0 through 31 are reserved ASCII printer control
characters, while 32 through 127, are the ASCII alpha numeric upper lower case
characters. The extended characters are from 128 to 255.
§
For the international character set, the upper 128 bit values code a collection of characters
and symbols.
§
The IBM compatible character set, the upper 128 bit values code a collection of block
graphic characters and special characters for drawing frames and boxes.
§
The printer defaults to the international character set on initial power up. To select an
alternate character set the following command strings are recognized.

§
Both fonts are monospaced, meaning for each character pitch selected (cpi) all the
characters are exactly the same width, making page layout easy to control. The MSP
compatible dot matrix font are based on a single 6x16 font table. The printer modifies this
table to yield various widths and weights.
§
Four different font tables are used to generate the courier font typefaces. On initial power
up, the printer defaults to 42 column, 21 cpi courier typeface. For the Courier normal
characters, the individual lines or strokes of each character are finer, giving a more airy
feel to the typeface. Courier bold characters have a heavier or thicker line width, putting
more emphasis in the text.
6-Bit Dot Addressable Graphics commands:
§
The printer will operate in 6-Bit Dot Addressable Graphics mode on receiving the Esc-G
graphic command. While in this mode the printer prints one dot line at a time on receipt
of 64 graphic characters or LF command. The LF command advances the paper by one
dot line.
§
Each horizontal graphic dot is made from 1x6 dot cells; the total number of dot cells per
line is 64, corresponding to the 384 total dots per line capacity. Each dot in a dot cell can
be turned on or off by sending specific ASCII characters. For example, #F hex will
energize all dots, while 40 hex de-energizes all the dots.
Select 6 Bit Addressable Graphic Mode:
<ESC> <G>

Section 7 ... Operating in MS-DOS World
For proper operation of the S2000T printers in the DOS environment, the following are required:
FOR SERIES 2000T - Serial Printer Version
§
Use DOS print command to print, or Write Direct to printer port.
§
Set the PC's communication baud using DOS MODE command: Printer and PC baud rate
and parity have to match.
Ÿ
§
Redirect PC's serial (COM) port to parallel (LPT)
Ÿ
§
MODE com1:19200,n,8,1
MODE lpt1:=com1:
Set the printer port for infinite retry using the DOS MODE command.
Ÿ
MODE LPT1:,,P
FOR SERIES 2000T - IrDA Printer Version
§
To operate the IrDA interface in MS-DOS environment, an IrDA device driver is
required. IrDA.SYS device driver is available from Extech.
§
Install the file IrDA.SYS to the boot fixed drive.
§
Next, modify the CONFIG.SYS file to include IrDA.SYS as one of the device drivers.
For example: DEVICE = C:\IrDA.SYS COM1 IRQ4 ADDR3F8 ; where C:\ is the path of
where you copied IrDA.SYS to, COM1 is the comport you choose, IRQ4 is the interrupt
request of that com port, and ADDR3F8 is the base address of that com port.
§
Finally, modify the AUTOEXEC.BAT file to include a command to reroute one of the
line printers to the com port, for example:
Ÿ
§
MODE LPT1:=COM1:
Re-boot DOS so that the modified CONFIG.SYS and AUTOEXEC.BAT take effect.
From that point on, anything you send to the rerouted line printer will go through the
IrDA.SYS driver.
Operating in Windows
§
To insure proper operation of the SERIES 2000 parallel version, in windows environment
the following are required.
§
Select Generic/text only printer driver.
§
Use Windows printer manager.
§
For the SERIES 2000 serial version, set the PC's serial port (COM1) baud rate and parity
to match printer.
§
Use printer Self-Test to verify baud rate and parity setting.
Page 21
Section 8 ... Supervised Mode Operation
§
The S2000T printers can be operated in a supervised mode. A single byte supervision
command <0x02> (^B), allows polling the status of the printer.
§
The printer transmits the three types of status strings upon receiving the supervision
request command byte:
•
Print buffer status:
<ESC> <B>
•
Battery Voltage status:
<ESC> <V> <4 ASCII digits><CR><LF>
•
MCR status:
<ESC> <M><4 ASCII digits><CR><LF>
<4 ASCII digits><CR><LF>
§
The four ASCII digits report the number of characters in print buffer, current battery
voltage level and Magnetic Card Reader (MCR) status. These digits are in "converted
hexadecimal" format. To reconvert these digits to hexadecimal form, subtract <0x30>
from each digit received.
§
In general, the printer can be polled as often as needed. The poll response is transmitted
as one complete transaction with no XON/XOFF, ^D or AuxOff in the middle of
response.
§
The examples below illustrate the supervisory response strings.
Print buffer status
§
For Example if <0x04D2> characters are in the print buffer, the following string is
returned upon receiving a <0x02> poll command.
<0x1B> <0x42>
<0x30> <0x34> <0x3D> <0x32>
<ESC> <B>
----<4 ASCII digits>----
<0x0D> <0x0A>
<CR>
<LF>
Magnetic card reader status
§
For Example, if the following Magnetic card read command is issued (esc-M-9-9-1-CRLF), the following is returned upon receiving a <0x02> poll command.
<0x1B> <0x4D>
<0x30> <0x39> <0x39> <0x31>
<0x0D> <0x0A>
<ESC> <M>
<time out>
<CR>
<track>
Page 22
<LF>
Printer battery level status
§
For Example, if the printer battery voltage is at 6.58 volts the following battery status
string is returned upon receiving a <0x02> poll command.
<0x1B> <0x4D> <0x00> <0x36> <0x35> <0x38>
§
<0x0D> <0x0A>
The internal battery voltage can vary from 5.00 (depleted) to 7.25 (full charge) volts.
Page 23
Section 9 ... Auto Power Down Feature
§
In order to conserve battery life the S2000T printer features a auto power down timer.
The power down timer defaults to 20 seconds on initial power up.
§
The auto power down timer can be set by sending recognized command string or disabled
by activating the <RTS> input line or setting the auto power down timer to zero.
§
The auto power down command string:
ESC
M

§
The first two characters "ESC" and "M" are command header characters. The next two
digits ASCII "01" through "99" sets the time-out in seconds, while the last two characters
are the command terminator characters.
§
Sending ESC-C resets the auto timer to initial power up default setting of 20 seconds.

Section 12 ... Magnetic Card Reader
Introduction
Ÿ
An optional Magnetic Card Reader is available for the S2000T series printers. This
option is designed to read Magnetic Cards conforming to ISO standards (ABA, IATA,
MINTS and THRIFT), convert the encoded signals to ASCII format and transmit the
information to the host computer or terminal.
Ÿ
Two Types of Magnetic Card Reader Heads are available. The part number, Model
number and functional description of each type are summarized below.

Interfacing to the Magnetic Card Reader
§
This section details the software steps required to access the Magnetic Card Reader from
a computer or from a terminal.
§
Select the printer
§
The Host Selects the S2000T printer by activating the RTS input line or sending wake-up
character to the printer.
§
The Printer Sends the XON command to the Host to indicate ready to receive Command
strings. The host has to wait for XON before proceeding.
§
Select the Magnetic Card Reader
Ÿ
§
The Host sends ASCII serial command string to enable the Magnetic Card Reader. The
printer turns on the <READY> LED if the proper command string is received.
Receive the ASCII Data Output from printer
Ÿ
Once the magnetic card is swiped by the operator, the printer transmits in ASCII format
<Track Data> or <Error Message>. A good read automatically turns off the reader. The
printer turns on the red <ERROR> LED if an error is encountered.
Page 42
Recognized Magnetic Card command strings
§
Six Magnetic Card command strings are recognized by the printer, these commands are
summarized in the table below:
Magnetic Card Command String
ESC - M - nn - 1 - CR
ESC - M - nn - 2 - CR
ESC - M - nn - 3 - CR
ESC - M - nn - 4 - CR
ESC - M - nn - 5 - CR
ESC - C
Description
Read Track1 only
Read Track2 only
Read Track3 only
Read Track1 and Track2 simultaneously
Read Track2 and Track3 simultaneously
Cancel Read
Turns off the <READY> LED
(nn = ASCII "01" through "99" seconds)
§
The command syntax is as follows:
ESC
M
(1)
§
§
CR
(4)
The first two characters "ESC" "M" turn on the Card Reader.
Set the Card Read Time-out
Ÿ
§
Track #
(3)
Turn On the Card Reader
Ÿ
§
nn
(2)
The next two digits "01" through "99" sets the time-out in seconds before the
turns off the Card Reader. A good read automatically turns off the reader.
printer
Select Track number to read
Ÿ
The Fifth character specifies the Track number's) to read.
Ÿ
Sending "1", "2" or "3" enables read of single track 1, 2 or 3.
Ÿ
Sending "4" enables simultaneous read of tracks 1 and 2.
Ÿ
Sending "5" enables simultaneous read of tracks 2 and 3.
Ÿ
There is currently no command to read tracks 1, 2 and 3 simultaneously.
Terminate command string
Ÿ
The S2000 waits for Carriage return character before start of the magnetic card read
process.
Track Data Output Format
§
The <Track Data> retrieved from magnetic card is transmitted to the Host in ASCII
format. The <Track Data> format is as follows:
Ÿ
/1/ <TRACK 1 DATA> <CR> <LF>
Ÿ
/2/ <TRACK 2 DATA> <CR> <LF>
Ÿ
/3/ <TRACK 3 DATA> <CR> <LF>
Page 43
§
The first three characters (/,1,/) flag the track number. The track data follows the third
character, CR-LF terminates the <Track Data> string.
Read Error Messages
§
§
All error messages are prefaced by <ESC><E> characters. Following these two characters
is a comma, the error number in ASCII (01 through 99), another comma, English
description of the error encountered and finally CR-LF terminating the <Error Message>
string. The syntax is as follows:
Ÿ
<ESC><E>, nn, Error text in ASCII, <CR><LF>
Ÿ
Where nn is error number encountered.
Nine (9) types of Read Error messages may be transmitted by the Mag card reader. The
following messages terminated with CR-LF are returned by the firmware:
Error #
Error Message Transmitted
01
Parity Error
02
Checksum Error
03
End Sentinel Not Found
04
Too Many Characters
05
Time-out Expired
06
Invalid Character
07
Invalid Track Number
08
Unsupported Track Selected
09

Read Error Messages
Error #
Error Message Description
01
The Parity of the character read is opposite of the
card default parity.
02
The Checksum calculated did not match the one on the
card. The checksum is calculated by Exclusive-OR'ing
all the valid data on the card including Begin Sentinel
and End Sentinel, but excluding the checksum byte.
03
End Sentinel must exist on all cards, Reader did not
find the End Sentinel.
04
The Maximum number of characters allowed for a track
was exceeded. This may happen if End Sentinel is not
found.
05
The command time-out has expired.
Page 44
06
The Track Reader Escape command string transmitted
by Host contained an invalid character.
07
Invalid Track Number is selected. Tracks "1", "2" or
“3" can be selected.
08
Unsupported Track is Selected. Tracks "1", "2" or
"3" can be selected.
09
"Cancel Request" error string is transmitted if Host
cancels Magnetic card read in process.
Magnetic Card Reader Operation in IrDA Mode
§
The way we handle the magnetic card data is the same as for printing data. Esc-M is sent
to the printer in the same way as any other data and the magnetic card reading data is sent
back the same way (only that it is in the reverse direction).
§
IrDA protocol has no knowledge of this at all, they are both "user data". Thus, at least in
principle, there is no need to modify anything in the IrDA Stack.
§
IrCOMM-3 wire raw is designed to deliver a single stream of "user data" in either
direction. "User data" can be the ASCII code for "A", <CR>, Esc, or anything. In our
case, "user data" happen to be Esc-M in one direction and magnetic card data in the
other.
§
IrLPT is almost identical to IrCOMM 3-wire raw, except that most people incorrectly
assume that data flows in one direction only.
§
Early printers were unidirectional; however, more are now bi-directional, like our Series
2000.

Section 13 ... Extech IR-XMODEM Protocol
§
This is a proposed protocol for bi-directional data transfer through an Infrared channel. The
protocol is based on packet transfer utilizing checksum error detection. Format of the data
packet is shown below:
SOH (0x01)
§
SEQ
CSEQ
...DATA [128 Bytes]...
Checksum
When powered on, the Extech printer will default to slave mode, requesting to receive
packets (sending a NAK character every 10 seconds). After receiving a magnetic card reader
request and the master closes the connection, the Extech printer switches to master mode. In
master mode the printer waits to receive a transmission request (NAK).
Summary of Extech IR-XMODEM transmission procedure:
