User’s Manual 5
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 BL2000 single-board computer has been tested and was found to
be in conformity with the following applicable immunity and emission
standards. The BL2010, BL2020, and BL2030 single-board computers
are also CE qualified as they are sub-versions of the BL2000 single-
board computer. Boards that are CE-compliant have the CE mark.
NOTE: Earlier versions of the BL2000 sold before 2003 that do not have the CE mark
are not CE-compliant.
Immunity
The BL2000 series of single-board computers meets the following EN55024/1998 immu-
nity 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 BL2000 series of single-board computers meets the following emission standards
using the enhanced-EMI PCB, Part# 175-0224 Rev. A, and the 668-0003 Rev. A Rabbit
2000 microprocessor.
•EN55022:1998 Class B
•FCC Part 15 Class B
Your results may vary, depending on your application, so additional shielding or filtering
may be needed to maintain the Class B emission qualification.
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

1.4.1 Design Guidelines
Note the following requirements for incorporating the BL2000 series of single-board com-
puters into your application to comply with CE requirements.
General
•The power supply provided with the Tool 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 BL2000 single-board computer to outdoor cables, the customer is
responsible for providing CE-approved surge/lighting 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.
•When installing or servicing the BL2000, it is the responsibility of the end-user to use
proper ESD precautions to prevent ESD damage to the BL2000.
Safety
•All inputs and outputs to and from the BL2000 series of single-board computers must
not be connected to voltages exceeding SELV levels (42.4 V AC peak, or 60 V DC).
•The lithium backup battery circuit on the BL2000 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 BL2000 to Other Devices
Since the BL2000 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.

2. GETTING STARTED
Chapter 2 explains how to connect the programming cable and
power supply to the BL2000.
2.1 BL2000 Connections
1. Attach the BL2000 to the plastic enclosure base.
Position the BL2000 over the plastic enclosure base as shown below in Figure 2. Attach
the BL2000 to the base at the top left and bottom right positions using the two 4-40 × ¼
screws supplied with the enclosure.
Figure 2. Attach BL2000 to Plastic Enclosure Base
The plastic enclosure base facilitates handling the BL2000 during development, and pro-
vides an attractive mounting alternative. Alternatively, you may wish to use standoffs to
protect the components on the other side of the board. The plastic enclosure is offered as a
separate option when individual BL2000 boards are purchased.
NOTE: Appendix B, “Plastic Enclosure,” provides additional information and specifica-
tions for the plastic enclosure.

2. Connect the programming cable to download programs from your PC and to debug the
BL2000.
Connect the 10-pin PROG connector of the programming cable to header J5 on the BL2000.
Ensure that the colored edge lines up with pin 1 as shown. (Do not use the DIAG connector,
which is used for monitoring only, as explained in Appendix E, “Programming Cable.”)
Connect the other end of the programming cable to a COM port on your PC. Make a note of
the port to which you connect the cable, as Dynamic C will need to have this parameter con-
figured. Note that COM1 on the PC is the default COM port used by Dynamic C.
Figure 3. Programming Cable Connections
3. Connect the power supply.
Plug the DC end of the power sup-
ply into jack J7, which is labeled
POWER IN, as shown in Figure 4.
4. Apply power.
Plug in the AC adapter. If you are
using your own power supply, it
must provide 9 V to 40 V DC—
voltages outside this range could
damage the BL2000.
The green PWR LED and the red
BAD LED should come on, indicat-
ing that the BL2000 is now ready to be used.
NOTE: A hardware RESET is done by unplugging the AC adapter, then plugging it back in, or
by momentarily grounding the board reset input at pin 9 on screw terminal header J2.

2.2 Installing Dynamic C
If you have not yet installed Dynamic C version 7.04 (or a later version), do so now by
inserting the Dynamic C CD in your PC’s CD-ROM drive. The CD will auto-install unless
you have disabled auto-install on your PC.
If the CD does not auto-install, click Start > Run from the Windows Start button and
browse for the Dynamic C setup.exe file on your CD drive. Click OK to begin the
installation once you have selected the setup.exe file.
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.
The Dynamic C User’s Manual provides detailed instructions for the installation of
Dynamic C and any future upgrades.
NOTE: If you have an earlier version of Dynamic C already installed, the default instal-
lation of the later version will be in a different folder, and a separate icon will appear on
your desktop.

10 Wildcat (BL2000)
2.3 Starting Dynamic C
Once the BL2000 is connected to your PC and to a power source, start Dynamic C by dou-
ble-clicking on the Dynamic C icon or by double-clicking on dcrabXXXX.exe in the Dynamic
C root directory, where XXXX are version-specific characters.
Dynamic C defaults to using the serial port on your PC that you specified during installa-
tion. If the port setting is correct, Dynamic C should detect the BL2000 and go through a
sequence of steps to cold-boot the BL2000 and to compile the BIOS. (Some versions of
Dynamic C will not do the initial BIOS compile and load until the first time you compile a
program.)
If you receive the message No Rabbit Processor Detected, the programming
cable may be connected to the wrong COM port, a connection may be faulty, or the target
system may not be powered up. First, check both ends of the programming cable to ensure
that it is firmly plugged into the PC and the programming port.
If there are no faults with the hardware, select a different COM port within Dynamic C.
From the Options menu, 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. You should receive a Bios compiled successfully message
once this step is completed successfully.
If Dynamic C appears to compile the BIOS successfully, but you then receive a communi-
cation error message when you compile and load a 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 > 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 > Communications
menu. Choose a lower debug baud rate.

2.4 PONG.C
You are now ready to test your set-up by running a sample program.
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.
This program does not test the serial ports, the I/O, or the TCP/IP part of the board, but
does ensure that the board is basically functional. The sample program described in
Section 5.3, “Run the PINGME.C Sample Program,” tests the TCP/IP portion of the
board.
2.5 Where Do I Go From Here?
NOTE: If you purchased your BL2000 through a distributor or Z-World partner, contact
the distributor or Z-World partner first for technical support.
If there are any problems at this point:
•Check the Z-World Technical Bulletin Board at www.zworld.com/support/bb/.
•Use the Technical Support e-mail form at www.zworld.com/support/support_submit.html.
If the sample program ran fine, you are now ready to go on to explore other BL2000 fea-
tures and develop your own applications.
Chapter 3, “Subsystems,” provides a description of the BL2000’s features, Chapter 4,
“Software,” describes the Dynamic C software libraries and introduces some sample pro-
grams, and Chapter 5, “Using the TCP/IP Features,” explains the TCP/IP features.

3.1.1 Headers and Screw Terminals
All BL2000 models are equipped with 1 × 12 screw terminal strips (J2, J4, J8, and J9) and
a 2-pin power jack (J7). The BL2000 and BL2010 also have the RJ-45 Ethernet jack (J6).
There is provision on the circuit board to accommodate 2 × 17 IDC headers or 1 × 17
friction-lock connectors with a pitch of 0.1" instead of the screw terminal strips. The
pinouts for these connectors are shown in Figure 6(b).
Figure 6(b). BL2000 Pinouts (other 0.1" headers)
3.1.2 Power Supply Pins
Instead of connecting an AC adapter to the power supply jack, J7, the input power supply
(9 V to 40 V DC) may be connected to pins 12 and 11 on header J2 (see Figure 6(a) or
Figure 6(b)).
Pin 12 on header J9 or J10 is normally GND by factory default, but may be changed to
Vcc by removing resistor R161 and installing resistor R160. See Appendix C, “Power
Supply,” for more information on this configuration and for information on backup-
battery options.

3.2 Digital I/O
3.2.1 Digital Inputs
The BL2000 has 11 digital inputs, IN0–IN10, each of which is protected over a range of
–36 V to +36 V. The inputs are factory-configured to be pulled up to +5 V, but they can
also be pulled down by moving the surface-mounted jumper at JP6 as shown in Figure 7.
