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.

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
