1.5 CE Compliance

Equipment is generally divided into two classes.

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

These limits apply over the range of 30–230 MHz. The limits are 7 dB higher for frequen­cies above 230 MHz. Although the test range goes to 1 GHz, the emissions from Rabbit­based systems at frequencies above 300 MHz are generally well below background noise
levels.

The BL4S200 single-board computer has been tested and was found to
be in conformity with the following applicable immunity and emission
standards. The BL4S210, BL5S220, and BL4S230 single-board
computers are also CE qualified as they are sub-versions of the BL4S200
single-board computer. Boards that are CE-compliant have the CE mark.

Immunity

The BL4S200 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 BL4S200 series of single-board computers meets the following emission standards.

• 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.

BL4S200 User’s Manual 11

1.5.1 Design Guidelines

Note the following requirements for incorporating the BL4S200 series of single-board
computers 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 BL4S200 single-board computer to outdoor cables, the customer

is responsible for providing CE-approved surge/lighting protection.

• Rabbit 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 BL4S200, it is the responsibility of the end-user to use

proper ESD precautions to prevent ESD damage to the BL4S200.

Safety

• All inputs and outputs to and from the BL4S200 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 BL4S200 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.

1.5.2 Interfacing the BL4S200 to Other Devices

Since the BL4S200 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 Rabbit distributor, and are also available on
our Web site at www.rabbit.com.

BL4S200 User’s Manual 12

1.6 Wi-Fi Certifications (BL5S220 Model only)

The systems integrator and the end-user are ultimately responsible for the channel range
and power limits complying with the regulatory requirements of the country where the end
device will be used. Dynamic C function calls and sample programs illustrate how this is
achieved by selecting the country or region, which sets the channel range and power limits
automatically. See Section 6.2.4.1 for additional information and sample programs dem­onstrating how to configure an end device to meet the regulatory channel range and power
limit requirements.

Only RCM5400W modules bearing the FCC certification are certified for use in Wi-Fi
enabled end devices associated with the BL5S220 model, and any applications must have
been compiled using Dynamic C v. 10.40 or later. The certification is valid only for
RCM5400W modules equipped with the dipole antenna that is included with the modules,
or a detachable antenna with a 60 cm coaxial cable (Digi International part number

29000105). Changes or modifications to this equipment not expressly approved by Digi
International may void the user's authority to operate this equipment.

In the event that these conditions cannot be met, then the FCC certification is no longer
considered valid and the FCC ID can not be used on the final product. In these circum­stances, the systems integrator or end-user will be responsible for re-evaluating the end
device (including the transmitter) and obtaining a separate FCC certification.

NOTE: Any regulatory certification is voided if the RF shield on the RCM5400W

module is removed.

1.6.1 FCC Part 15 Class B

The RCM5400W RabbitCore module has been tested and found to comply with the limits
for Class B digital devices pursuant to Part 15 Subpart B, of the FCC Rules. These limits
are designed to provide reasonable protection against harmful interference in a residential
environment. This equipment generates, uses, and can radiate radio frequency energy, and
if not installed and used in accordance with the instruction manual, may cause harmful
interference to radio communications. However, there is no guarantee that interference
will not occur in a particular installation. If this equipment does cause harmful interfer­ence to radio or television reception, which can be determined by turning the equipment
off and on, the user is encouraged to try and correct the interference by one or more of the
following measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment and the receiver.

• Connect the equipment into an outlet on a circuit different from that to which the

receiver is connected.

• Consult the dealer or an experienced radio/TV technician for help.

Chapter 2 explains how to connect the programming cable and
power supply to the BL4S200.

2.1 Preparing the BL4S200 for Development

Position the BL4S200 as shown below in Figure 2. Attach the four stand-offs supplied
with the Tool Kit in the holes at the corners as shown.

Figure 2. Attach Stand-Offs to BL4S200 Board

The stand-offs facilitate handling the BL4S200 during development, and protect the bot­tom of the printed circuit board against scratches or short circuits while you are working
with the BL4S200.

NOTE: If you ever need to remove the RabbitCore module, take care to keep the BL4S200

main boards and their corresponding RabbitCore modules paired since the RabbitCore
modules store calibration constants specific to the BL4S200 main board to which they
are plugged in. If you use a RabbitCore module from a different model in the BL4S200
series, your specific BL4S200 model may no longer operate as designed.

1. Connect the programming cable to download programs from your PC and to program
and debug the BL4S200.

Connect the 10-pin PROG connector of the programming cable to header J1 on the
BL4S200’s RabbitCore module (the programming header is labeled J2 on the BL5S220
and BL4S230 models). Ensure that the colored edge lines up with pin 1 as shown. (Do not
use the DIAG connector, which is used for monitoring only.) Connect the other end of the
programming cable to an available USB port on your PC or workstation.

Connect the other end of the programming cable to an available USB port on your PC or
workstation.

Your PC should recognize the new USB hardware, and the LEDs in the shrink-wrapped
area of the USB programming cable will flash — if you get an error message, you will
have to install USB drivers. Drivers for Windows XP are available in the Dynamic C

Drivers\Rabbit USB Programming Cable\WinXP_2K folder — double-click
DPInst.exe to install the USB drivers. Drivers for other operating systems are available

online at www.ftdichip.com/Drivers/VCP.htm.

BL4S200 User’s Manual 17

Figure 3. Programming Cable Connections

NOTE: Never disconnect the programming cable by pulling on the ribbon cable.

Carefully pull on the connector to remove it from the header.

2. Connect the power supply to header J5 on the BL4S200 as shown in Figure 4. Be sure
to match the latch mechanism with the top of the connector to header J5 on the
BL4S200 as shown. The Micro-Fit® connector will only fit one way.

Figure 4. Power Supply Connections

3. Apply power.

Once all the other connections have been made, you may connect power to the BL4S200.

First, prepare the AC adapter for the country where it will be used by selecting the plug.
The Tool Kit presently includes Canada/Japan/U.S., Australia/N.Z., U.K., and European
style plugs. Snap in the top of the plug assembly into the slot at the top of the AC adapter
as shown in Figure 4, then press down on the spring-loaded clip below the plug assembly
to allow the plug assembly to click into place. Release the clip to secure the plug assembly
in the AC adapter.

Plug in the AC adapter. The red LED next to the power connector at J5 should light up.
The BL4S200 is now ready to be used.

CAUTION: Unplug the power supply while you make or otherwise work with the connections

to the headers. This will protect your BL4S200 from inadvertent shorts or power spikes.

2.2.1 Hardware Reset

A hardware reset is done by unplugging the power supply, then plugging it back in, or by
pressing the RESET button located just below the RabbitCore module.

BL4S200 User’s Manual 18

2.3 Installing Dynamic C

If you have not yet installed Dynamic C version 10.42 (or a later version), do so now by
inserting the Dynamic C CD from the BL4S200 Tool Kit in your PC’s CD-ROM drive. If
autorun is enabled, the CD installation will begin automatically.

If autorun is disabled or the installation does not start, use the Windows Start | Run menu
or Windows Disk Explorer to launch setup.exe from the root folder of the CD-ROM.

The installation program will guide you through the installation process. Most steps of the
process are self-explanatory.

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.

The online documentation is installed along with Dynamic C, and an icon for the docu­mentation 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 docu-

ments 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.

Once your installation is complete, you will have up to three icons on your PC desktop.
One icon is for Dynamic C, one opens the documentation menu, and the third is for the
Rabbit Field Utility, a tool used to download precompiled software to a target system.

If you have purchased any of the optional Dynamic C modules, install them after installing
Dynamic C. The modules may be installed in any order. You must install the modules in
the same directory where Dynamic C was installed.

BL4S200 User’s Manual 19

2.4 Starting Dynamic C

Once the BL4S200 is connected to your PC and to a power source, start Dynamic C by
double-clicking on the Dynamic C icon on your desktop or in your Start menu. Select

Store Program in Flash on the “Compiler” tab in the Dynamic C Options > Project
Options
Serial Converter

menu. Then click on the “Communications” tab and verify that Use USB to

is selected to support the USB programming cable. Click OK.

You may have to select the COM port assigned to the USB programming cable on your
PC. In Dynamic C, select Options > Project Options, then select this COM port on the
“Communications” tab, then click OK. You may type the COM port number followed by

Enter on your computer keyboard if the COM port number is outside the range on the

dropdown menu.

2.5 Run a Sample Program

You are now ready to test your set-up by running a sample program.

Use the File menu to open the sample program PONG.C, which is in the Dynamic C

SAMPLES folder. Press function key F9 to compile and run the program. The STDIO

window will open on your PC and will display a small square bouncing around in a box.

This program shows that the CPU is working. The sample program described in
Section 5.2.3, “Run the PINGME.C Demo,” tests the TCP/IP portion of the board.

2.5.1 Troubleshooting

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 to see that the red power LED next to header J5
is lit. If the LED is lit, check both ends of the programming cable to ensure that it is firmly
plugged into the PC and the programming header on the BL4S200 with the marked (col­ored) edge of the programming cable towards pin 1 of the programming header. Ensure
that the module is firmly and correctly installed in its connectors on the BL4S200 board.

If Dynamic C appears to compile the BIOS successfully, but you then receive a communi­cation 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

Options > Project Options menu. Select a slower Max download baud rate. Click OK

Serial Options dialog on the “Communications” tab in the Dynamic C

to save.

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

Options > Project Options menu. Choose a lower debug baud rate. Click OK to save.

Serial Options dialog on the “Communications” tab in the Dynamic C

Press <Ctrl-Y> to force Dynamic C to recompile the BIOS. You should receive a Bios

2.8 Where Do I Go From Here?

NOTE: If you purchased your BL4S200 through a distributor or Rabbit partner, contact

the distributor or partner first for technical support.

If there are any problems at this point:

• Use the Dynamic C Help menu to get further assistance with Dynamic C.

• Check the Rabbit Technical Bulletin Board and forums at www.rabbit.com/support/bb/

and at www.rabbit.com/forums/.

• Use the Technical Support e-mail form at www.rabbit.com/support/.

If the sample program ran fine, you are now ready to go on to explore other BL4S200
features and develop your own applications.

When you start to develop your application, run USERBLOCK_READ_WRITE.C in the

SAMPLES\UserBlock folder to save the factory calibration constants before you run any

other sample programs in case you inadvertently write over them while running another
sample program.

Chapter 3, “Subsystems,” provides a description of the BL4S200’s features, Chapter 4,
“Software,” describes the Dynamic C software libraries and introduces some sample
programs, and Chapter 5, “Using the Ethernet TCP/IP Features,” explains the TCP/IP fea­tures.

3.1.1 Connectors

Standard BL4S200 models are equipped with seven polarized 2 × 5 Micro-Fit® connectors
(J1–J4 and J9–J11), one polarized 2 × 7 Micro-Fit® connector (J12), and one polarized
2 × 3 connector at J7 to supply power (DCIN and +5 V) to up to two RabbitNet periph-

®

eral expansion boards. The polarized 2 × 2 Micro-Fit

connector at J5 is for the main

power supply connections.

The RJ-45 jacks at J6 and J8 labeled RabbitNet are serial I/O expansion ports for use with
RabbitNet peripheral expansion boards. The RabbitNet jacks do not support Ethernet con­nections. Be careful to make your Ethernet connection to the Ethernet jack on the Rab­bitCore module (note that the wireless BL5S220 and BL4S230 models do not have an
Ethernet port).

3.2.1 Configurable I/O

3.2.1.1 Digital Inputs

The BL4S200 has 32 configurable I/O, DIO0–DIO31, each of which may be configured
individually in software as either digital inputs or as sinking digital outputs. By default, a
configurable I/O channel is a digital input, but may be set as a sinking digital output by
using the setDigOut() function call. The inputs are factory-configured to be pulled up
to +5 V, but they can also be pulled up to +K or DCIN, or pulled down to 0 V in banks by
changing a jumper as shown in Figure 7.

CAUTION: Do not simultaneously jumper more than one setting on a particular
jumper header (JP9, JP8, JP1, and JP2) when configuring a bank of configurable I/O.

The actual switching threshold is approximately

1.40 V. Anything below this value is a logic 0,
and anything above 1.90 V is a logic 1. The con­figurable I/O are each fully protected over a
range of 0 V to +36 V, and can handle short
spikes from -5 V to +40 V.

NOTE: If the inputs are pulled up to +Kx, the

voltage range over which the digital inputs
are protected changes to 5 V - Kx to +36 V.

CAUTION: Do not allow the voltage on a configurable I/O pin to exceed +Kx to

When you configure a configurable I/O
pin as a sinking output, be sure to con­nect an external voltage source up to
36 V DC across the corresponding
+Kx and GND on connector J1, J2, J9,
or J10, and set the pullup jumper on
the corresponding JP1/JP2/JP8/JP9
header to +Kx.

3.2.1.3 Configurable I/O Special Uses

Individual configurable I/O pins may be used for interrupts, input capture, as quadrature
decoders, or as PWM outputs. The use of these channels for PWM, interrupts, input cap­ture, and as quadrature decoders is described in the Rabbit RIO User’s Manual.

Blocks of configurable I/O pins are associated with counters/timers on the three Rabbit RIO
chips that support them. Table 5 provides complete details for these associations.

Configurable I/O pins DIO30 and DIO31 fully support all input-associated special uses
such as interrupts and input captures, but otherwise they are limited to function only as
regular digital I/O pins because their outputs are latch-driven since sufficient Rabbit RIO
resources are not available to support their use for specialized outputs.

Appendix D provides further details on the blocks and pins associated with each Rabbit
RIO chip to facilitate configuring each block consistently and to identify misconfigured
pins when a software function call returns a Mode Conflict error code.
