Rabbit 2000 Dev Kit Getting Started

1. Introduction

The Rabbit® 2000 is a new and powerful microprocessor. Both hardware and software design are easy with the Rabbit.

This Development Kit has the essentials that you need to design your own a microprocessor-based system, and includes a complete software development system (Dynamic C). This kit contains a powerful single-board computer (the BL1810). With this kit you will be able to write and test complex software. You will be able to prototype circuits that interface to a Rabbit 2000 microprocessor.

1.1 Development Kit Contents

The Rabbit 2000 Development Kit contains the following items:

• BL1810 single-board computer.

• Prototyping Board.

• AC adapter, 12 V DC, 1 A. (Included only with Development Kits sold for the North American market. A header plug leading to bare leads is provided to allow overseas users to connect their own power supply with a DC output of 7.5-25 V.)

NOTE	The linear voltage regulator becomes rather hot for voltages above 15 V.

• 10-pin header to DE9 programming cable with integrated level-matching circuitry.

• Dynamic C CD-ROM, with complete product documentation on disk.

• This Getting Started manual.

• A bag of accessory parts for use on the Prototyping Board.

• Screwdriver.

• Rabbit 2000 Processor Easy Reference poster.

• Registration card.

1.2 Development Software

The BL1810 in the Development Kit uses the Dynamic C development environment for rapid creation and debugging of runtime applications. Dynamic C provides a complete development environment 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 2., "Detailed Installation Instructions." 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 Rabbit 2000 microprocessor. 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 Rabbit 2000 microprocessor to effective use.

1.3.1 Additional Product Information

Detailed information about the BL1810 will be found in the Jackrabbit (BL1800) User's Manual, provided on the accompanying CD-ROM in both HTML and Adobe PDF format.

NOTE	We recommend that anyone not thoroughly familiar with Z-World embedded control systems at least read through the rest of this manual to gain the necessary familiarity 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 BL1810:

• Dynamic C User's Manual

• Dynamic C Function Reference Manual

• Rabbit 2000 Microprocessor User's Manual

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 provide 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 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 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.

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 Rabbit-based systems at frequencies above 300 MHz are generally well below background noise levels.

The 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 BL1800 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 BL1800 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 BL1800 series boards that carry the CE mark.

• EN55022:1998 Class B

• FCC Part 15 Class B

In order for the BL1800s 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 communication. Depending on your application, you may need to add ferrite absorbers to the 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 BL1800s 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 the Jackrabbit model BL1810 included with the Rabbit 2000 Development Kit.

1.4.1 Spectrum Spreader

BL1800s that carry the CE mark have a Rabbit 2000 microprocessor that features a spectrum spreader, which helps to mitigate EMI problems. By default, the spectrum spreader is on automatically for BL1810 boards that carry the CE mark when used with Dynamic C 7.32 or later versions so as to maintain CE compliance, but the spectrum spreader may also be turned off or set to a stronger setting. The means for doing so is through a simple change to the following BIOS line.

#define ENABLE_SPREADER 1  // Set to 0 to disable spectrum spreader
                           // 1 to enable normal spreading, or
                           // 2 to enable strong spreading.

NOTE	The strong spectrum-spreading setting is not needed for any BL1810.

There is no spectrum spreader functionality for BL1800s that do not carry the CE mark or when using any BL1800 with a version of Dynamic C prior to 7.30.

1.4.2 Design Guidelines

Note the following requirements for incorporating the BL1800 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 BL1800 single-board computer to outdoor cables, the customer is responsible for providing CE-approved surge/lightning protection.

• Rabbit Semiconductor 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. Rabbit Semiconductor also recommends using properly shielded I/O cables in noisy electromagnetic environments.

• When installing or servicing the BL1800, it is the responsibility of the end-user to use proper ESD precautions to prevent ESD damage to the BL1800.

Safety

• For personal safety, all inputs and outputs to and from the BL1800 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 BL1800 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.

1.4.3 Interfacing the BL1800 to Other Devices

Since the BL1800 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.
