1.2 Development Software
The Jackrabbit uses the Dynamic C development environment for rapid creation and
debugging of runtime applications. Dynamic C provides a complete development environ-
ment with integrated editor, compiler and source-level debugger. It interfaces directly with
the target system, eliminating the need for complex and unreliable in-circuit emulators.
Dynamic C must be installed on a Windows workstation with at least one free serial USB
or COM port for communication with the target system. See Chapter 3., “Software Instal-
lation & Overview,” for complete information on installing Dynamic C.
1.3 How to Use This Manual
This Getting Started manual is intended to give users a quick but solid start with the Jack-
rabbit. It does not contain detailed information on the hardware capabilities or the
Dynamic C development environment. Most users will want more detailed information on
some or all of these topics in order to put the Jackrabbit to effective use.
1.3.1 Additional Product Information
Detailed information about the Jackrabbit will be found in the Jackrabbit (BL1800)
User’s Manual, provided on the accompanying CD-ROM in both HTML and Adobe PDF
format.
TIP: We recommend that anyone not thoroughly familiar with Z-World embedded con-
trol systems at least read through the rest of this manual to gain the necessary familiar-
ity to make use of the more advanced information.
1.3.2 Additional Reference Information
In addition to the product-specific information contained in the Jackrabbit (BL1800)
User’s Manual, several higher level reference manuals are provided in HTML and PDF
form on the accompanying CD-ROM. Advanced users will find these references valuable
in developing systems based on the Jackrabbit:
•Dynamic C User’s Manual
•Dynamic C Function Reference Manual
•Rabbit 2000 Microprocessor User’s Manual

Getting Started Manual 5
1.3.3 Using Online Documentation
We provide the bulk of our user and reference documentation in two electronic formats,
HTML and Adobe PDF. We do this for several reasons.
We believe that providing all users with our complete library of product and reference
manuals is a useful convenience. However, printed manuals are expensive to print, stock
and ship. Rather than include and charge for manuals that every user may not want, or pro-
vide only product-specific manuals, we choose to provide our complete documentation
and reference library in electronic form with every development kit and with our Dynamic
C development environment.
NOTE: The most current version of Adobe Acrobat Reader can always be downloaded
from Adobe’s web site at http://www.adobe.com.
We recommend that you use version 4.0 or later.
Providing this documentation in electronic form saves an enormous amount of paper by
not printing copies of manuals that users don’t need.
Finding Online Documents
The online documentation is installed along with Dynamic C, and an icon for the docu-
mentation menu is placed on the workstation’s desktop. Double-click this icon to reach the
menu. If the icon is missing, create a new desktop icon that points to default.htm in the
docs folder, found in the Dynamic C installation folder.
The latest versions of all documents are always available for free, unregistered download
from our web sites as well.
Printing Electronic Manuals
We recognize that many users prefer printed manuals for some uses. Users can easily print
all or parts of those manuals provided in electronic form. The following guidelines may be
helpful:
•Print from the Adobe PDF versions of the files, not the HTML versions.
•If your printer supports duplex printing, print pages double-sided.
•If you do not have a suitable printer or do not want to print the manual yourself, most
retail copy shops (e.g. Kinkos, AlphaGraphics, etc.) will print the manual from the PDF
file and bind it for a reasonable charge—about what we would have to charge for a
printed and bound manual.

6Jackrabbit (BL1800)
1.4 CE Compliance
Equipment is generally divided into two classes.
These limits apply over the range of 30–230 MHz. The limits are 7 dB higher for frequen-
cies above 230 MHz. Although the test range goes to 1 GHz, the emissions from Rabbit-
based systems at frequencies above 300 MHz are generally well below background noise
levels.
The Jackrabbit BL1800 single-board computer has been tested and was
found to be in conformity with the following applicable immunity and
emission standards. The BL1810 and BL1820 single-board computers
are also CE qualified as they are sub-versions of the BL1800 single-
board computer. Boards that are CE-compliant have the CE mark.
NOTE: Earlier versions of the BL1800 sold before 2002 that do not have the CE mark
are not CE-complaint.
Immunity
The Jackrabbit series of single-board computers meets the following EN55024/1998
immunity standards.
•EN61000-4-3 (Radiated Immunity)
•EN61000-4-4 (EFT)
•EN61000-4-6 (Conducted Immunity)
Additional shielding or filtering may be required for a heavy industrial environment.
Emissions
The Jackrabbit series of single-board computers meets the following emission standards
with the Rabbit 2000 spectrum spreader turned on and set to the normal mode. The spectrum
spreader is only available with Rev. C or higher of the Rabbit 2000 microprocessor. This
microprocessor is used in all Jackrabbit series boards that carry the CE mark.
•EN55022:1998 Class B
•FCC Part 15 Class B
In order for the Jackrabbit boards to meet these EN55022:1998 Class B standards, you
must add ferrite absorbers to the serial I/O cables used for RS-232 and RS-485 serial com-
munication. Depending on your application, you may need to add ferrite absorbers to the
CLASS A CLASS B
Digital equipment meant for light industrial use Digital equipment meant for home use
Less restrictive emissions requirement:
less than 40 dB µV/m at 10 m
(40 dB relative to 1 µV/m) or 300 µV/m
More restrictive emissions requirement:
30 dB µV/m at 10 m or 100 µV/m

Getting Started Manual 7
digital I/O cables. Your results may vary, depending on your application, so additional
shielding or filtering may be needed to maintain the Class B emission qualification.
NOTE: If no ferrite absorbers are fitted, the Jackrabbit boards will still meet
EN55022:1998 Class A requirements as long as the spectrum spreader is turned on.
The spectrum spreader is on by default for Jackrabbit models BL1810 and BL1820. The
spectrum spreader is off by default for the Jackrabbit model BL1800, and must be turned
on with at least one wait state in order for the BL1800 model to be CE-compliant. Section
2.7.3 in the Jackrabbit (BL1800) User’s Manual provides further information about the
spectrum spreader and its use, and includes information on how to add a wait state.
1.4.1 Design Guidelines
Note the following requirements for incorporating the Jackrabbit series of single-board
computers into your application to comply with CE requirements.
General
•The power supply provided with the Development Kit is for development purposes
only. It is the customer’s responsibility to provide a CE-compliant power supply for the
end-product application.
•When connecting the Jackrabbit single-board computer to outdoor cables, the customer
is responsible for providing CE-approved surge/lightning protection.
•Z-World recommends placing digital I/O or analog cables that are 3 m or longer in a
metal conduit to assist in maintaining CE compliance and to conform to good cable
design practices. Z-World also recommends using properly shielded I/O cables in noisy
electromagnetic environments.
•When installing or servicing the Jackrabbit, it is the responsibility of the end-user to use
proper ESD precautions to prevent ESD damage to the Jackrabbit.
Safety
•For personal safety, all inputs and outputs to and from the Jackrabbit series of single-
board computers must not be connected to voltages exceeding SELV levels (42.4 V AC
peak, or 60 V DC). Damage to the Rabbit 2000 microprocessor may result if voltages
outside the design range of 0 V to 5.5 V DC are applied directly to any of its digital
inputs.
•The lithium backup battery circuit on the Jackrabbit single-board computer has been
designed to protect the battery from hazardous conditions such as reverse charging and
excessive current flows. Do not disable the safety features of the design.
1.4.2 Interfacing the Jackrabbit to Other Devices
Since the Jackrabbit series of single-board computers is designed to be connected to other
devices, good EMC practices should be followed to ensure compliance. CE compliance is
ultimately the responsibility of the integrator. Additional information, tips, and technical
assistance are available from your authorized Z-World distributor, and are also available
on our Web site at www.zworld.com.

10 Jackrabbit (BL1800)
2.2 Prototyping Board
The Prototyping Board included in the Development Kit makes it easy to connect a Jack-
rabbit board to a power supply and a PC workstation for development. It also provides
some basic I/O peripherals (switches and LEDs), as well as a prototyping area for more
advanced hardware development.
For the most basic level of evaluation and development, the Prototyping Board can be
used without modification.
As you progress to more sophisticated experimentation and hardware development, modi-
fications and additions can be made to the board without modifying or damaging the Jack-
rabbit board itself.
The Prototyping Board is shown below in Figure 2, with its main features identified.

2.2.1 Prototyping Board Features
•Power LED—The power LED lights whenever power is connected to the Prototyping
Board.
•Reset Switch—A momentary-contact, normally open switch is connected directly to the
Jackrabbit’s /RESET_IN pin. Pressing the switch forces a hardware reset of the system.
•I/O Switches and LEDs—Four momentary-contact, normally open switches are con-
nected to the PB2–PB5 pins of the Rabbit 2000 microprocessor on the Jackrabbit, and
may be read as inputs by sample applications.
Four LEDs are connected to the PA1–PA4 pins of the of the Rabbit 2000 microproces-
sor on the Jackrabbit, and may be driven as output indicators by sample applications.
•Prototyping Area—A generous prototyping area has been provided for the installation
of through-hole components. Several areas for surface-mount devices are also avail-
able. (Note that there are SMT device pads on both top and bottom of the Prototyping
Board.)
•Extension Headers—The complete pin sets of the Jackrabbit are duplicated at these
two sets of headers. Developers can solder wires directly into the appropriate holes, or,
for more flexible development, 40-pin header strips can be soldered into place. See
Figure 1 for the header pinouts.
•RS-232—Two 3-wire or one 5-wire RS-232 serial port are available on the Prototyping
Board. Refer to the Prototyping Board schematic (090-0088) for additional details.
A 10-pin 0.1-inch spacing header strip is installed at J1 to permit connection of a ribbon
cable leading to a standard DE-9 serial connector.

2.3 Development Hardware Connections
There are three steps to connecting the Prototyping Board for use with Dynamic C and the
sample programs:
1. Attach the Jackrabbit to the Prototyping Board.
2. Connect the programming cable between the Jackrabbit and the workstation PC.
3. Connect the power supply to the Jackrabbit.

Getting Started Manual 13
2.3.1 Attach Jackrabbit to Prototyping Board
To attach the Jackrabbit board to the Prototyping Board, turn the Jackrabbit board over so
that the battery is facing up. Plug the pins from headers J4 and J5 on the bottom side of the
Jackrabbit board into the header sockets at J2 and J6 on the Prototyping Board as indicated
in Figure 3.
Figure 3. Attach Jackrabbit Board to Prototyping Board
NOTE: It is important that you line up the pins on headers J4 and J5 of the Jackrabbit
board exactly with the corresponding pins of header sockets J2 and J6 on the Prototyp-
ing Board. The header pins may become bent or damaged if the pin alignment is offset,
and the Jackrabbit might not work. Permanent electrical damage to the may also result
if a misaligned Jackrabbit is powered up.
Press the Jackrabbit’s pins firmly into the Prototyping Board headers.

2.3.2 Connect Programming Cable
The programming cable connects the Jackrabbit to the PC running Dynamic C to down-
load programs and to monitor the Jackrabbit during debugging.
Connect the 10-pin connector of the programming cable labeled PROG to header J3 on
the Jackrabbit board as shown in Figure 4. Be sure to orient the marked (usually red) edge
of the cable towards pin 1 of the connector. (Do not use the DIAG connector, which is used
for a normal serial connection.)
NOTE: Use only the programming cable that has a red shrink wrap around the RS-232
level converter (Z-World part number 101-0513), which is supplied with the Develop-
ment Kit. Other Z-World programming cables might not be voltage-compatible or their
connector sizes may be different.
Figure 4. Power and Programming Cable Connections

2.3.3 Connect Power
When all other connections have been made, you can connect power to the Jackrabbit.
Hook up the connector from the wall transformer to header J1 on the Jackrabbit board as
shown in Figure 4. The orientation of this connector is not important since the VIN (posi-
tive) voltage is the middle pin, and GND is available on both ends of the three-pin header J1.
Plug in the wall transformer. The Jackrabbit board and the Prototyping Board are ready to
be used.
NOTE: A RESET button is provided on the Prototyping Board (see Figure 3) to allow
hardware reset without disconnecting power.
To power down the Jackrabbit, unplug the power connector from J1. You should discon-
nect power before making any circuit adjustments in the prototyping area, changing any
connections to the board, or removing the Jackrabbit from the Prototyping Board.
2.3.3.1 Overseas Development Kits
Development kits sold outside North America include a header connector that may be
connected to 3-pin header J1 on the Jackrabbit. The connector may be attached either way
as long as it is not offset to one side. The red and black wires from the connector can then
be connected to the positive and negative connections on your power supply. The power
supply should deliver 7.5 V–25 V DC at 5 W.

16 Jackrabbit (BL1800)
2.4 Run a Sample Program
If you already have Dynamic C installed, you are now ready to test your programming
connections by running a sample program.
If you are using a USB port to connect your computer to the Jackrabbit, choose Options >
Project Options and select “Use USB to Serial Converter” under the Communications
tab.
Find the file PONG.C, which is in the Dynamic C SAMPLES folder. To run the program,
open it with the File menu (if it is not still open), compile it using the Compile menu, and
then run it by selecting Run in the Run menu. The STDIO window will open and will dis-
play a small square bouncing around in a box.

2.4.1 Troubleshooting
If Dynamic C appears to compile the BIOS successfully, but you then receive a communi-
cation error message when you compile and load the sample program, it is possible that
your PC cannot handle the higher program-loading baud rate. Try changing the maximum
download rate to a slower baud rate as follows.
•Locate the Serial Options dialog in the Dynamic C Options > Project Options >
Communications menu. Select a slower Max download baud rate.
If a program compiles and loads, but then loses target communication before you can
begin debugging, it is possible that your PC cannot handle the default debugging baud
rate. Try lowering the debugging baud rate as follows.
•Locate the Serial Options dialog in the Dynamic C Options > Project Options >
Communications menu. Choose a lower debug baud rate.
If there are any other problems:
•Check to make sure you are using the PROG connector, not the DIAG connector, on the
programming cable.
•Check both ends of the programming cable to ensure that they are firmly plugged into
the PC and the programming port on the Jackrabbit.
•Ensure that the Jackrabbit is firmly and correctly installed in its connectors on the
Prototyping Board.
•Select a different COM port within Dynamic C. From the Options menu, select
Project Options, then select Communications. Select another COM port from the
list, then click OK. Press <Ctrl-Y> to force Dynamic C to recompile the BIOS. If
Dynamic C still reports it is unable to locate the target system, repeat the above steps until
you locate the active COM port.
