t ISA expansion slot in PC/104 form factor. This expansion slot is primarily intended
for the PC/104 VGA adapter card option for use with an external monitor or LCD
touch screen display. Alternatively, an analog or digital I/O card, solid state memory
disk, or super I/O card (for floppy and hard drives, etc.) can be installed.
t Two general purpose PC Card (PCMCIA) slots. The top slot supports one type I, II
or III card for installing a hard disk, wireless network adapter, modem or other
device. The bottom slot accepts one type I or II card and is intended for holding a
memory card loaded with DOS for boot up and other system software. However,
either slot may be used to boot from and both slots are general purpose.
t Built-in 10BaseT Ethernet interface for direct connection to an existing Ethernet
network. This feature makes the unit just like any other client PC on the network.
t Built-in 4-line by 40-character LCD display with back light. The display reflects a
portion of the total video text screen according to the current position of the cursor.
Alternatively, a specified fixed portion of the 80 x 25 VGA text screen can be viewed
on the 4 x 40 display.
t Two standard RS-232 serial ports (COM1 and COM2) and an optional RS-485
adapter (COM4) for point-to-point communications.
t Internal PS-2 style keyboard and mouse input connectors for adding a full sized
external keyboard and a mouse.
t Built-in speaker and connection for an additional external speaker. The speaker
provides audible confirmation of bar code readings and boot-up status.
t A real-time clock powered by the rechargeable CMOS battery when power is not
applied to the unit. Approximately 3,000 hours of clock and CMOS operation is
possible from the battery without power. A jumper may be removed to disconnect
the battery if extended storage of the unit is required.
t Internal power supply regulator accepts AC or DC voltages from 18 to 28 VAC (24
VAC nominal) or 9 to30VDCsothata distributed wiring system maybeemployed.
External 110 VAC or 220 VAC power supply adapters with 24 VAC output can be
used to power the unit. Also a built-in battery charger circuit is provided for the
unit’s battery back-up option.
Note: The unit’s power switch can be disabled, preventing an operator from
accidentally turning off the unit.

FMT 3000 Hardware Reference Manual - Introduction
Data Collection Features
t Built-in bar code decoder supporting Codabar, Code 39, UPC, EAN/JAN/APN,
Interleaved 2 of 5, Industrial 2 of 5, MSI, Code 11, Code 128, Matrix 2 of 5, Plessy,
Code 16K, “K” Code, “WA” Code, postal code 1 and postal code red. The unit can
be programmed to ignore those code types that are not used in the system.
t Three interface connectors support bar code wands, slot readers and laser scanners.
Two DB9-pin connectors (for bar code and laser scanners) and one internal 5-pin
connector (for slot readers) are provided. Fully decoded and undecoded (less
expensive) laser input devices can be used. Bar code data received via the unit’s laser,
bar code or slot reader connectors may be “wedged” into the keyboard making it
appear as though the data was typed at the keyboard. This is performed by software
drivers. Physically wedging a device into the PS2 keyboard connector is an option
as well, as long as the device is designed to do so.
t An optional “good read” beep can be generated through the unit’s speaker, or an
external speaker, when a code is successfully read.
Mechanical Features
t The unit’s heavy duty case is injection molded from fire-retardant ABS. The main
circuit board is mounted to a metal base pan which forms the back of the unit. The
hinged case seals against foam gasket material on the metal base to resist moisture
and dust from entering the unit.
t A cutout in the base pan allows cable access to internal I/O connectors through the
rear of the unit. A plate covers the cutout when not in use. When routing cables
through the rear cable access opening, precautions should be taken to prevent any
water from entering the unit. A removable plug at the upper right side of the case
allows additional cable routing for externally mounted slot and card readers.
t Hinges connect the base pan to the plastic cover and provide 180 degree rotation to
provide access to cabling, memory cards and the PC/104 expansion connector. The
cover secures with a keyed lock at the top of the unit to prevent undesired access to
internal components.
t The65keyQWERTYkeypadismolded fromsiliconerubberandsealed withametal
bezel. Clear coated keycaps prevent abrasion and wear. A polycarbonate overlay
covers the metal bezel.
t Various I/O connectors (including bar code, laser and the COM2 port) are available
at the recessed area under the case front.

Optional Features
t Three mounting options are available: A flat wall mounting plate, a desk mount tilt
stand, and a wall mount tilt enclosure. Also, four adhesive backed rubber feet are
included to rest the unit flat on a table top. The wall plate allows mounting the unit
on a vertical surface. The desk mount tilt stand raises the unit at a 20 degree angle
for desk top use. The tilt wall enclosure angles the unit at 26 degrees for wall
mounting. Room inside this enclosure can house a power supply adapter and
cabling.
t Bracketsareavailableformountingbarcodeslotreadersandmagneticstripereaders
on the left or right hand sides of the unit when used in conjunction with the above
mounting options.
Note: The flat wall mount plate allows mounting of slot and stripe readers
on the right-hand side of the unit only.
t Data collection input device options include a keyboard “wedged” magnetic stripe
reader (track 1 and 2), a 7.5 mil red bar code slot reader, a 7.5 mil IR bar code slot
reader and a bar code laser wand. The magnetic stripe reader connects to the unit’s
internal PS/2 keyboard connector through a 6-pin mini DIN plug. The 7.5 mil red
and IR bar code readers interface to the unit through a 5-pin header inside the unit.
t The digital I/O option, which is implemented on the power I/O board of the unit,
provides six optically isolated digital inputs and two digital relay outputs for
applicationslikemachinemonitoringandaccesscontrol. Aremovable terminal strip
with screw-down type terminal connections allow external wires to interface with
the digital inputs and outputs.
t COM4 on the unit primarily supports the RS-485 serial communications option.
The option board plugs into a 10-pin connector on the power I/O board. The RS-
485 option board converts RS-232 level serial communication signals to half duplex
bidirectional isolated RS-422/485. Sockets are provided on the board for custom
installationofterminationandlinebiasresistors. A3-pinplugconnectorisprovided
for connection to an RS-485 line.
t Each unit contains a built-in battery charger for the optional NICAD battery back-
up pack. This pack mounts on top of, and plugs into, the power I/O board. It will
power the unit for 20 to 90 minutes depending on which options are installed (VGA
card, PC Cards, Digital I/O, etc.) and activity. An “on-battery” detect circuit senses
when the input power has been lost and the battery has taken over. A “low battery”
detect circuit automatically determines when the battery pack needs charging. A
“very low battery” circuit sense when only a few seconds of power are left. These

status signals allow for storing temporary buffers and for closing applications before
losing power.
t The PC/104 VGA adapter card option allows the unit to use an external full screen
monitor or LCD touch screen display. The primary use of the unit’s PC/104
connector is for VGA card installation. The built-in 4 x 40 LCD display is
operational even when the VGA adapter is used. Using the VGA adapter, a pointing
device, keyboard and sufficient disk space, the unit will be capable of running

FMT 3000 Hardware Reference Manual - Introduction
Functional Description
As seen in Block Diagram of the Unit on page 1-6, the unit is comprised of the following
functional sections:
tThe CPU area (CPU, memory, chipset, internal bus),
tCommunications port control (COM1-4 and LPT1 for the integral LCD display
interface),
tPC/104 expansion interface,
tBar code section (which also interfaces COM3),
tKeyboard control, PC Card (PCIMCA) interfaces,
tEthernet control and interface,
tPower supply, speaker, and digital I/O option section.
These functional areas are described below.
CPU
The CPU is a low power 486-DX2 capable of running at 33 MHz with external bus
components and at 66 MHz internally. Being low power, the CPU clock can also be slowed
to reduce power consumption through internal power management functions. The CPU has
an internal write-through cache and math coprocessor to further enhance performance.
The CPU chipset has power management features that reduce or eliminate the need for
external hardware controls or software programming to monitor and control system power
usage. The chipset also has other I/O lines to enable or disable COM ports, LCD backlight,
the on-board speaker, the Ethernet adapter and other system components.
There are 4 volume levels that the speakers may be set to (LOW, MED, HIGH, Very High).
The volume level is set via “INT 2F interrupt” functionality described in Chapter 9, Custom
Function Reference, of the FMT 3000 Software Manual.
Memory
The unit includes 1 MB of DRAM on-board. The on-board memory can be increased by
installing additional memory in the 72-pin SIMM expansion connector located on the unit’s
main board. The total system memory can be expanded from 1MB to 17MB (all possible
combinations are: 1, 2, 3, 5, 9, and 17MB total depending on whether a 1, 2, 4, 8 or 16MB
SIMM is added). The SIMM must be 70nSec or faster and operate in FPM (Fast Page Mode).

1-10
FMT 3000 Hardware Reference Manual - Introduction
Note: No system setup procedures are required after installing new memory
since the memory controller automatically scans the DRAM sites and
determines the amount of memory.
Communication Port Control
The unit has four serial communications ports (COM1 - 4) and one internal parallel port
(LPT1). The LPT1 port is used to interface the LCD display (described later in this section).
Two dual 550 type UARTS are used to provide the 4 serial ports.
COM1,COM2
Serialcommunications ports COM1 and COM2aregeneralpurpose9-pinRS-232 ports that
accept and output standard RS-232 signal voltage levels. The standard DB9-pin male
connector for COM1 is located inside the unit’s case, and the standard DB9-pin male
connector for COM2 is located at the recessed area at the front of the unit. Using ordinary
communications software, these ports can be used for any common serial communication
tasks (point-to-point or external modem communications).
COM3
COM3 is dedicated to interfacing to the bar code decoder. The decoder circuitry, which
provides three separate bar code and magnetic card reader interfaces, is described under the
Bar Code Decoder on page 1-12.
Communication PortWedging
Data from COM3 can be redirected (“wedged”) into the keyboard buffer via software
drivers. This allows data decoded from bar code devices appear directly in the keyboard
input stream. Information on keyboard wedging is found in Chapter 4, Bar Coding,of the
FMT 3000 Software Manual.
COM4
COM4 is primarily dedicated to supporting the RS-485 port option board which mounts to
an internal 10-pin connector on the power I/O board. The connector carries COM4’s Rx,
Tx,RTS/andCTS/signalsaswellas+5Vand GND to drive the RS-485optionboard. Signal
inputs unused by the RS-485 interface are tied to ground.
Normally, COM4 is enabled and uses IRQ 11. A category in the Setup utility (Chapter 2,
Installation) allows COM4 to be disabled (or enabled), making the port assignment and
associated IRQ available for use by PCMCIA or PC/104 devices.

FMT 3000 Hardware Reference Manual - Introduction
RS-485 Option Board
The RS-485 option board converts TTL level serial communication signals to half duplex
isolated RS-422/485. Sockets are provided on the option board for customer installation of
termination and line bias resistors. A 3 pin-plugable connector is provided for connection to
the RS-485 line.
LCD Display
As shown in the Block Diagram (refer to Figure 1-1 on page 1-6), the integral 4 x 40 LCD
display is driven by the LPT1 port of the “communications port section”. Internal firmware
drivers control the display. The Optrix B fluid supertwist LCD display has an industry
standard display window and integral backlight.
Through cursor movements, a display tracker function allows the user to view a selected 4 x
40windowofvideo screen area. Code extracted from the BIOS ROM on boot-up andplaced
in upper memory controls display interface functions. See Chapter 5, LCD Display,of the
FMT 3000 Software Manual for information on controlling and operating the 4 x 40 LCD
display. (Also check any “Readme” text files on the utility disks supplied with the product for
the latest information.)
Note: LPT1 is dedicated to supporting the display and is not accessible
through any general I/O connector for other use. If printing directly
from the unit is required, the printer must interface the unit through
a serial port or the through the network.
PC/104 Expansion Interface
A 16 bit PC/104 based expansion site is provided on board through a pair of socket
connectors (64 and 40 standard pins). The PC/104 standard defines an ISA expansion
connector in a pin and socket format for compact computer designs. The unit’s case, when
closed, allows one PC/104 card to be installed. For development purposes, more than one
card can be plugged in when the case is open.
On the FMT 3000, the primary use for this expansion site is for VGA card installation.
Alternative uses include analog and digital I/O cards, solid state memory disks, super I/O
cards (for floppy and hard drives), etc.
Several differences in the PC/104 expansion connector implementation on this unit from the
full PC/104 standard are listed below:

1-12
FMT 3000 Hardware Reference Manual - Introduction
t+5 V power is supplied to the connector. +12 V, -12 V and - 5 V are not provided,
however, a 4-pin Molex style header is provided on the main board to supply these
voltages from an external power source if required.
tDMA channels 0,1 and 2 are supported.
tIRQ7 and IRQ 12 are reserved by the CPU board and are NOT brought out to the
PC/104 connector
tNo Bus Master support.
The limitations listed may affect some analog I/O data acquisition PC/104 cards, but
otherwise should have little affect on the use of the expansion site.
Bar Code Decoder
The bar code decoder is implemented using a microcontroller programmed with decode
algorithms. The decoder communicates with the unit through COM3. The communication
parameter settings are fixed at 9600 baud using space parity.
Programming decoder options, such as enabling bar code symbologies or disabling reading
of data from a device, is done by sending various ASCII command codes to COM3. Decoded
input data can be either received through COM3, or “wedged” into the keyboard input
stream, making it appear that the data was typed at the keyboard. See the FMT 3000
SoftwareManualforbarcode programmingdetails.Both fullydecoded(more expensive)and
undecoded (less expensive) laser input devices can be used, increasing flexibility and
potentially reducing system cost.
Three separate connectors and signal paths are provided for connection of bar code wands,
slot readers, and laser scanners. Located at the front connector area on the unit is a DB9-pin
connector for bar code readers and a DB9-pin connector for non-decoded lasers. The DB9
connector labeled “Barcode” is for decoded lasers or wand type devices and the DB9
connector labeled “Laser” is for undecoded laser scanners only. Inside the unit’s case is a 5-
pin header for connecting magnetic slot readers. The decoder circuit imposes signal polarity
requirements on devices: bar code and slot devices must be black high, lasers devices must
be white high.
Normally, the decoder operates in a polled fashion, alternately enabling and sampling each
of the three device’s data line looking for data. If only one device is used, the other two may
be disabled to improve performance. Also, bar code symbologies may be eliminated to
increase performance.
The unit also provides for a beep to be generated by the internal speaker or external auxiliary
speaker when a good read of the bar code or laser device occurs. The beep may be disabled

1-13
FMT 3000 Hardware Reference Manual - Introduction
(see Chapter 9, Custom Function Reference, of the FMT 3000 Software Manual) if the bar
code device generates its own “good read” beep to prevent dual good read beeps.
Keyboard Control
The Keyboard Control section is used to scan the integral keypad, provide external keyboard
and mouse interfaces, and to interface the CPU. The connectors for the external keyboard
and mouse are located inside the unit’s case. Both connectors are 6-pin mini DIN PS/2 style.
Full 102 key keyboards are supported. The mouse interface is serial bus type.
Although not related to the functioning of the Keyboard Control section, the main chip used
in the keyboard scanner also provides the general purpose digital I/O lines used to implement
the optional digital I/O interface section (described later under the Power Supply and Digital
I/O section) and the speaker volume control.
Dual PC Card Slots (PCMCIA)
The 6720 dual slot PCMCIA controller (from CIRRUS Logic) provides full PCMCIA
memory and I/O card support for two PCMCIA slots. This includes internal buffering and
power control logic.
A dual stacked PCMCIA connector is provided on the main board of the unit. This part
stands off the PCB by 5mm to allow components to be located underneath it. Either Type I
or II cards may be inserted in either slot and a Type III card is allowed in the top slot.
Note: No +12 V supply is present on the board for flash programming, as
many flash cards can now operate from +5 V only.
Hot insertion (i.e., with power on) of PC Cards is supported (when both card and socket
services are loaded) but not recommended since the case must be open to install cards. Other
exposed components may be damaged or shorted if objects are accidentally dropped in the
unit while the power is on.
Chapter 6, PC Card Slots,of the FMT 3000 Software Manual discusses software support for
PC Card or PCMCIA devices.
Ethernet Interface
Each unit has a built-in Ethernet controller with a twisted-pair interface. The Ethernet
interface includes transmit and receive filters and diagnostic LED indicators (located inside
the unit’s case). The controller performs collision detection, re-transmission, automatic
polarity detection and correction on the twisted-pair, 10Base-T, cable. An 8-pin RJ-45
