Introduction & Overview 1

The RabbitCore RCM2200 is an advanced module that incorporates the
powerful Rabbit 2000
I/O ports and a 10Base-T Ethernet port, all on a PCB just half the size of a
business card.

™ microprocessor, flash memory, static RAM, digital

1.1 RCM2200 Description

The RCM2200 is a small-footprint module designed
for use on a motherboard tha t su ppli es power and
interface to real- worl d I/ O d evic es. I ts two 26- pin
connection headers provide 26 parallel user I/O
lines, shared with three serial ports, along wi th data,
address and control li nes. A f ourt h se rial port and
three additional I/O lin es are available on the pro­gramming header.

A fully-enabled slave po rt permits glueless master­slave interface with another Rabbit-based system.
The slave port may also be used wit h non- Rabbit
systems, although additi onal logi c may be required.

The RCM2200 is equipped with a 10Base-T Ether ­net port, 256k flash memory and 128k st ati c RAM.

1.1.1 Other Factory V ersions

To accommodate developers with specif ic needs,
alternate versions of th e RCM2200 mod ule can be
obtained in production quanti ties on special order.

In addition, a variant of t he RCM220 0 is avai lab le.
The RCM2300 omits the Ethernet connecti vit y but
offers a much small er f ootprint, one-half the size of
the RCM2200.

1.2 Developme nt Soft ware

The RCM2200 module uses the Dynamic C devel­opment environment for rapi d cr eat ion a nd debug­ging of runtime applications. Dynamic C provides a
complete development env iro nmen t wi th i nte grat ed
editor , compi ler and s ourc e-l evel debugger. It int er­faces directly with the ta rget sy stem, elimina ting the
need for complex and unreliabl e in- ci rcui t e mul a­tors.

Dynamic C must be installed on a Windows work­station with at least one f re e ser ia l ( COM) por t f or
communication with the target system. See Chapter
3, “Software Installatio n & Overview,” for complete
information on installing Dynamic C.

TIP… We recommend that anyone not

thoroughly familiar with Z-World
controllers at least read thr ough t he
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 produc t- spec ifi c i n for mati on con­tained in the RabbitCore RCM2200 User’s Manual,
several higher -l evel ref er ence manuals are provided
in HTML and PDF form on the accompanying CD­ROM. Advanced users will find these re fer ence s
valuable in developing s yste ms base d on the
RCM2200 module:

IMPORTANT! The RCM2200 mod-

ule requires Dynamic C v7.04 or
later for development. A compati­ble version is included on the
Development Kit CD-ROM.

1.3 How to Use This Manual

This Getting St art ed manual is int ende d to give
users a quick but solid start with the RCM2200
module. It does not contain deta il ed i nfor mati on on
the module hardware capabilit ies, the Dynamic C
development environment, or t he TCP/I P sof twar e
support for the integr at ed Eth ernet port. Most users
will want more detailed informa ti on on s ome or a ll
of these topics in order to p ut the RCM2200 module
to effective use.

1.3.1 Additional Product Information

Detailed information ab out t he RabbitCore
RCM2200 will be found in the RabbitCore
RCM2200 User’s Manual, provided on the acc om­panying CD-ROM in both HTML and Adobe PDF
format.

Some advanced users may choose to skip the rest of
this introductory manual and proceed directly with
the detailed hardware and software information in
the User’s manual.

1.3.3 Using Online Documentation

We provide the bulk of our user a nd reference docu­mentation in two electronic f ormat s, HTML and
Adobe PDF. We do this for several reasons .

We believe that providing al l use rs wi th o ur co m­plete library of product and reference manuals is a
useful convenience. However, printed manuals are
expensive to print, stoc k and s hip . Ra the r th an
include and charge for manual s t hat every user may
not want, or provide only product -spe cif ic manual s,
we choose to provide our complete do cumentation
and reference library in e lec tr onic form with every
development kit and with our Dynamic C de velop­ment 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.

Getting Started Manual Introduction & Overview 1–3

Providing this documentation i n el ect roni c f orm
saves an enormous amount of paper by no t pr inting
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 me ntat ion
menu is placed on the workstati on ’s desktop. Dou-
ble-click this icon to r each the menu. If the icon is
missing, create a new desktop icon that points to
default.htm in the docs fo lder, found in the
Dynamic C installation fo lder.

The latest versions of all documents are always
available for free, u nreg ist ere d downl oad f rom our
web sites as well.

Printing Electronic Manuals

We recognize that many users pre fer pri nte d ma nu­als for some uses. Users can easi ly print all or parts
of those manuals provided in el ect roni c form. The
following guidelines may be hel pful :

• 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 yoursel f, most re tai l
copy shops (e.g. Kinkos, AlphaGraphi cs, etc.)
will print the manual fr om the PDF file and
bind it for a reasonable cha rge—about what
we would have to charge for a pri nt ed and
bound manual.

2.2 Overvi ew of the

Prototyping Board

power supply against damage from
reversed raw power connections.

The Prototyping Board included i n the Develop­ment Kit makes it easy to connect an RCM2200
module to a power supply and a PC workstat io n for
development. It also provides some bas ic I /O
peripherals (switches and LEDs), as well as a proto­typing area for more advanc ed ha rdwar e deve lop ­ment.

For the most basic level o f eva lua tion and develop­ment, the Prototyping Board can be u sed wi thout
modification.

As you progress to more sophis ti cat ed experimenta­tion and hardware development, modif ic ations and
additions can be made to the boar d wit hout mod ify ­ing or damaging the RabbitCore mo dule it sel f.

The Prototyping Board is shown in Fi gure2–1 on
the next page, with its main features identified.

2.2.1 Prototyping Board Features

Power Connection A 3-pin header is

provided for connection to the power
supply. Note that it is symmetrical, with
both outer pins connected to ground and
the center pin connected to the raw V+
input. The cable of the wall transformer
provided with the North American ver­sion of the development kit ends in a
connector that is correctly connected in
either orientation.

Users providing their own power supply
should ensure that it delivers 8–24 VDC
at not less than 500 mA. The voltage reg­ulator will get warm in use. (Lower sup­ply voltages will reduce thermal
dissipation from the device.)

Regulated Power Supply The raw

DC voltage provided at the POWER IN
jack is routed to a 5-volt linear voltage
regulator, which provides stable power to
the RabbitCore module and the Prototyp­ing Board. A Shottky diode protects the

Power LED The power LED lights

whenever power is connected to the
development board.

Reset Switch A momentary-contact,

normally-open switch is connected
directly to the RabbitCore’s

/RES pin.

Pressing the switch forces a hardware
reset of the system.

I/O Switches & LEDs Two momen-

tary-contact, normally-open switches are
connected to the PB2 and PB3 pins of the
master RabbitCore module and may be
read as inputs by sample applications.

Two LEDs are connected to the PE1 and
PE7 pins of the master module, and may
be driven as output indicators by sample
applications.

The LEDs and switches are connected
through JP1, which has traces shorting
adjacent pads together. These traces may
be cut to disconnect the LEDs, and an 8­pin header soldered into JP1 to permit
their selective reconnection with jump­ers. See Figure 2–2 on page 2–4 for
details.

Expansion Areas The Prototyping

Board is provided with several unpopu­lated areas for expansion of I/O and
interfacing capabilities. See the next sec­tion for details.

Prototyping Area A generous proto-

typing area has been provided for the
installation of through-hole components.
Vcc (5 VDC) and Ground busses run
around the edge of this area. An area for
surface-mount devices is provided to the
right of the through-hole area. (Note that
there are SMT device pads on both top

2.2.2 Prototyping Board Expansion

The Prototyping Board comes with several unpopu­lated areas, which ma y be filled with components t o
suit the user’s development needs. After you have
experimented with the sample programs in
Section 3.5, you may wish to expand the bo ard’s
capabilities for further experimentation and devel­opment. Refer to the Prototyping Bo ard s chemat ic
(090–0122) for details as ne cessary .

Module Extension Headers

The com­plete pin set of both the Master and Slave
RabbitCore modules are duplicated at
these two sets of headers. Developers can
solder wires directly into the appropriate
holes, or, for more flexible development,
26-pin header strips can be soldered into
place. See Figure 1–1 on page 1–2 for the
header pinouts.

RS-232 Port Two 2-wire or one 4-wire

RS-232 serial port can be added to the
Prototyping Board by installing a driver
IC and four capacitors. The Maxim
MAX232CPE driver chip or a similar
device is recommended for the U2. Refer
to the Prototyping Board schematic for
additional details.

A 10-pin 0.1-inch spacing header strip
can be installed at J6 to permit connec­tion of a ribbon cable leading to a stan­dard DE-9 serial connector.

To disconnect these devices and permit
the pins to be used for other purposes, cut
the traces between the pin rows of JP1.
Use a knife or similar tool to cut or
break the traces crossing JP1 in the area
between the silk-screened arrows, as
indicated in Figure 2–2 below.

Use jumpers across the positions on JP1
if you need to reconnect any of the
devices later on.

Figure 2–2: JP1, seen from the underside

of the Prototyping Board. The connections to

the LEDs and switches ma y be bro ken by

cutting the four traces between the arrows.

2.3 Development Hardware

Connections

There are four steps to connecting the Prototyping
Board for use with Dynamic C and the sampl e pro­grams:

All RS-232 port components mount to
the underside of the Prototyping Board,
between the Master module connectors.

NOTE: The RS-232 chip, capacitor s

and header strip are available from
electronics distributors such as
Digi-Key.

Four I/O pins from the module are hard-

1. Attach the Rabbit Core modu le t o the Proto-

typing Board.

2. Connect the programmi ng ca ble b etwee n

the RabbitCore module and the workst a­tion PC.

3. Connect the module’s Ethernet port to a

PC’s Ethernet port, or to an Ethernet net­work.

4. Connect the power su pply t o t he Prototyp-

2.3.1 Attach Module to

Prototyping Board

Turn the Rabbi tCor e RCM2200 module so that the
Ethernet connector end of the mo dule exte nds off
the Prototyping Board, as shown in Figure 2–3
below. Align the module headers J4 and J5 i nto
sockets J1 and J2 on the Prot oty ping Boa rd.

Although you can install a s ingl e modu le into either
the Master or Slave position, a ll of t he development
board features (switches, LEDs, s eri al port drivers,
etc.) are connected to the Mast er position. We rec­ommend you install a single module i n the Mas te r
position.

IMPORTANT! It is important that you

line up the pins of the RabbitCor e
module headers J4 and J5 exactly
with the corresponding pins of
headers J1 and J2 on the Prototyp­ing Board. The header pins may
become bent or damaged if the pin
alignment is offset, and the module

will not work. Permanent elect rical
damage to the module may also
result if a misaligned modul e is
powered up.

Press the module’s pins firmly into the Prototyping
Board headers. The installed modul e i s shown i n

Note that the stripe on the cable is towards pin 1 of the header J5.

2.3.2 Connect Programming Cable

The programming cable connects the RabbitCore
module to the PC workstation running Dynamic C,
to permit download of programs and monitoring for
debugging.

Connect the 10-pin connect or of the progr amming
cable labeled PROG to header J1 on t he Rabb it ­Core RCM2200 module as shown in Fi gure 2–5. Be
sure to orient the marke d (us ual ly r ed) e dge of the
cable towards pin 1 of the conne ctor. (Do not use
the DIAG connector, which is us ed fo r a n ormal
serial connection.)

Connect the other end of th e pro gramming cabl e to
a COM port on your PC. Make a note of the por t t o
which you connect the cable, as Dyna mi c C need s

to have this parameter configured when it is
installed.

NOTE: COM 1 is the default port used

by Dynamic C.

2.3.3 Connect Ethernet Network Cable

Programming and development can be done wit h
the RabbitCore RCM2200 without connec ting the
Ethernet port to a network. However, if you will be
running the sample programs that use the Ethernet
capability or will be doing Ethernet-enabled devel­opment, you should connect the RabbitCore mod­ule’s Ethernet port at this time.

There are four options for connecting the Rabbit­Core module to a network for dev elop ment and

2–6 Hardware Setup RabbitCore RCM2200

runtime purposes. The firs t t wo opti ons permit total
freedom of action in select ing network addresses
and use of the “network,” as no action can interfere
with other users. We recommend one of these
options for initial deve lopment .

• No LAN — The simplest alternative for

desktop development. Connect the Rabbit­Core’s Ethernet port directly to the wor ksta -
tion’s network int erf ace car d, usi ng an RJ -45
crossove r cable. A crossover cable is a special
cable that flips some connec tions be twee n the
two connectors and permits dir ect conne ction
of two client systems. A sta ndar d RJ-4 5 net ­work cable will not work for this purpose.

• Micro-LAN — Another simple alternative

for desktop development. Use a small Ethe r­net 10Base-T hub and connect both t h e work ­station’s network interface car d and t he
RabbitCore’s Ethernet port to it, usi ng st an-
dard network cables.

The following options requir e mo re c are in ad dress
selection and testing act ions, as conflicts with other
users, servers and systems can occur:

2.3.4 Connect Power

When all other connections have b een made , you
can connect power to the RabbitCor e Prototyping
Board.

Hook the connector from the wal l trans for me r t o
header J5 on the Prototyping Boar d as s hown in
Figure 2–6 below . The conn ector may be attached
either way as long as it is not offset to one side.

Plug in the wall transformer. The power LED on
the Prototyping Board should light up. The Rabbit­Core 2000 and the Prototyping Board are now
ready to be used.

NOTE: A RESET button is provided

on the Prototyping Board to allow
hardware reset without disconnect­ing power.

To power down the Prototyping Board, unplug t he
power connector from J5. You should disconnect
power before making any circu it adju stment s i n the
prototyping area, changing any connec ti ons t o the
board, or removing the RabbitCore module from the
board.

• LAN — Connect the RabbitCore’s Et hernet

port to an existing LAN, pref era bly one to
which the development workstat ion is already
connected. You will need to obtain IP
addressing information fro m yo ur ne twork
administrator.

• WAN — The RabbitCore RCM2200 is

capable of direct connecti on t o the Internet
and other Wi de Area Networks, but excep­tional care should be used wit h IP a ddre ss
settings and all network-rel ated prog ramming
and development. We recommend that devel­opment and debugging be done on a l ocal
network before connectin g a Rabbi tCor e
system to the Internet.

TIP… Checking and debugging the

initial setup on a micro-LAN is rec­ommended before connecting the
system to a LAN or WAN.

2.4 Where Do I Go From Here?

We recommend that you proceed to the next chap­ter and install Dynamic C ( if y ou do not already
have it installed), t hen r un t he fi rst sample program
to verify that the RabbitCor e module and Prototyp­ing Board are set up and functioning correctly.

If everything appears to be workin g, we rec ommend
the following sequence of act ion:

1. Run all of t he sample progra ms described in

Section 3.5 to get a basic familiarity with
Dynamic C and the RabbitCore module’s
capabilities.

2. For further dev elop ment, refer to the Rab-

bitCore RCM2200 User’s Manual for
details of the module’s hardware and sof t-
ware components.

A documentation icon should have been
installed on your workstation’s desktop;

Software Installation & Overview 3

To develop and debug programs for the RabbitCore RCM2200 (and for all
other Z-World and Rabbit Semiconductor hardware), you must install and
use Dynamic C. This chapter tak es you thro ugh the ins tallati on of Dynam ic
C, and then provides a tour of its major features with respect to the Rabbit­Core RCM2200 module.

3.1 An Overview of Dynamic C

Dynamic C integrates the fo llo wing development
functions into one program:

• Editing

• Compiling

• Linking

• Loading

• In-Circuit Debugging

In fact, compiling, linking and loading are one func­tion. Dynamic C does not use an In-Cir cui t Emula ­tor; programs being developed a re downloaded to
and executed from the “target” system via an
enhanced serial-port conne cti on. Pr ogra m de vel op­ment and debugging take place sea mless ly across

Getting Started Manual Software Installation & Overview 3–1

this connection, greatly sp eedi ng sys te m de vel op­ment.

Other features of Dynamic C include:

• Dynamic C has an easy-to-use built-in text
editor. Programs can be exec uted and
debugged interactively at the source-code or
machine-code level. Pull-down menus and
keyboard shortcuts for most co mmands make
Dynamic C easy to use.

• Dynamic C also supports assembly language
programming. It is not necessary t o leave C or
the development system t o wri te a sse mbl y
language code. C and assembly language may
be mixed together.

• Debugging under Dynamic C includes the
ability to use printf commands, watch

expressions, breakpoint s and othe r advanced
debugging features. Watch expressions can be
used to compute C expressions invol vi ng the
target’s prog ram variables or functio ns. W atch
expressions can be evalua ted whil e stopped at
a breakpoint or while the target is running its
program.

• At least 50 MB of free hard drive space

• At least one free COM (serial) port for com-

munication with the tar get sys tems

• A 10Base-T Ethernet network interface port
(optional if you will not be using the
RCM2200’s Ethernet port)

• Dynamic C provides extensions to the C lan­guage (such as shared and protected var iables,
costatements and cofunctions ) t hat support
real-world embedded system development.
Interrupt service routines may be written in C.
Dynamic C supports cooperative and preemp­tive multi-tasking.

• Dynamic C comes with many function librar­ies, all in source code. These libraries sup port
real-time programming, ma chin e le vel I/O,
and provide standard string and math func­tions.

• Dynamic C compiles directly to memory .
Functions and libraries ar e compiled and
linked and downloaded on-the-f ly. On a fast
PC, Dynamic C can load 30,000 bytes of code
in 5 seconds at a baud rate of 115,200 bps.

3.2 System Requirements

To install and run Dynamic C, your syste m must be
running one of the following ope rat ing systems:

• Windows 95

• Windows 98

• A CD-ROM drive (for software installation)

3.3 Installing Dynamic C

Insert the Dynamic C CD-ROM in t he drive on your
PC. If autorun is enabled, the CD ins tal la ti on wil l
begin automatically.

If autorun is disabled or t he i nst all at ion ot her w ise
does not start, use the Windows
or Windows Disk Explo rer to l aunc h
from the root folder of the CD-ROM.

The installation program wil l gui de yo u thr ough t he
installation process. M ost ste ps of the process are
self-explanatory and n ot c overed in this section.
Selected steps that may be conf usi ng to some use rs
are outlined below. (Some of the installation utility
screens may vary slightl y fr om thos e shown.)

3.3.1 Program & Documentation

File Location

Dynamic C’s application, library and document ation
files can be installed i n any c onveni ent location on
your workstation’s hard drives.

Start | Run menu

SETUP.EXE

• Windows NT

• Windows ME

• Windows 2000

3.2.1 Hardware Requirements

The PC on which you install Dynamic C for d evel ­opment of RCM2200-based systems should have
the following hardware:

• A Pentium or later microprocessor

• 32 MB of RAM

3–2 Software Installation & Overview RabbitCore RCM2200

The default location, as shown i n the example
above, is in a folder named for t he version of
Dynamic C, placed in the root folder of the C: drive.
If this location is not suitable, enter a different root
path before clicking

Next >. Files are placed in the

specified folder, so do not set this location to a
drive’s root directory.

3.3.2 Installati on Type

Dynamic C has two components that can be
installed together or se par ate ly. One component is
Dynamic C itself, with the develo pme nt e nvir on­ment, support files and libr ari es. The other compo­nent is the documentation li brar y in HTML and
PDF formats, which may be left uninst all ed t o save
hard drive space or instal led elsewhere (on a sepa­rate or network drive, for ex ample) .

3.3.3 Select COM Port

Dynamic C uses a COM (serial) port to co mmuni­cate with the target deve lopment system. The instal­lation allows you to choose th e COM port that will
be used.

The default selection, as sh own in t he example
above, is COM1. You may select any available port
for Dynamic C’s use. If you are not certai n which
port is available, select COM1. This s ele cti on ca n
be changed later within Dynamic C.

The installation type is selected in the installation
menu shown above. The options are:

Typical Installation — Both Dynamic C

•

and the documentation librar y will be
installed in the spec if ied f ol d er ( def ault ).

Compact Installation — Only Dynamic C

•

will be installed.

Custom Installation — You wil l be

•

allowed to choose which component s ar e
installed. This choice is u sef ul to install or
reinstall just the documentation.

NOTE: The installation utility does not

check the selected COM port in any
way. Specifying a port in use by
another device (mouse, modem,
etc.) may cause temporary prob­lems when Dynamic C is started.

3.3.4 Desktop Icons

Once your installation is complete, you wil l have up
to three icons on your PC desktop, a s sho wn below.

One icon is for Dynamic C, one opens the documen ­tation menu, and the third is f or t he Rabb it Field
Utility, a tool used to download precompil ed so ft­ware to a target syst em.

Getting Started Manual Software Installation & Overview 3–3

3.4 Starting Dynamic C

Once the RabbitCore module is set up and con­nected as described i n Chapter 2 and Dynamic C ha s
been installed, start Dynami c C by doub le- cli cki ng
on the Dynamic C icon. Dynamic C should star t,
then look for the targ et system on the COM port you
specified during instal lat ion (by de faul t, COM1).
Once detected, Dynamic C should go thro ugh a
sequence of steps to cold-boot the module and com­pile the BIOS.

If you receive the messag e begi nni ng “BIOS

successfully compiled and
loaded…” you are ready to continue with the

sample programs in the next c hapt er.

3.4.1 Communication Error Messages

If you receive the messag e “No Rabbit Pro­cessor Detected,” the programming c abl e

may be connected to a different COM port, a con­nection may be faulty, or the target system may not
be powered up. First, check to see that the power
LED on the Prototyping Board is lit . If it is , chec k
both ends of the pr ogrammin g cable to ens ure that it
is firmly plugged into the PC and the RabbitCore’s
programming port, with the pin-1 e dge of the cabl e
matched to the pin-1 mark on the board. I f you are
using the Prototyping Board, ens ure t hat the mo d­ule is firmly and correctly installe d in its connector s.

If there are no faults wit h the hardware, select a dif­ferent COM port within Dynamic C. From t he
Options menu, select Communications. The dial og
shown should appear.

Select another COM port from the list, then click
OK. Press
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.

If Dynamic C appears to compile the BIOS succ ess ­fully, but you then receive a communica tion error
message, it is possible that your PC cannot handle
the 115,200 b ps bau d rat e. Try changing the baud
rate to 57,600 bps using this pr oced ure:

Ctrl-Y to force Dynamic C to recompile

1. In Dynamic C, open the BIOS so urce code

file, RABBITBIOS.C.
Change the line:

#define USE115KBAUD 1

to read as follow s:

#define USE115KBAUD 0

2. Open the Communications dialog in the

Dynamic C
from the

3. Save the changes us ing Fi le > Save.

Options menu. Select 57,600

Baud Rate list and click OK.

You should now receive th e "BIOS success­fully compiled" message without a follow-

ing communication error.

3.5 Sample Programs

To help familiarize you with the Ra bbit Core
RCM2200 modules, Dynamic C includes several
sample programs. Loading, executing a nd st udyi ng
these programs will give you a so li d hands-on over­view of the RabbitCore’s capabilities, as well as a
quick start with Dynamic C as an appl ic ation devel­opment tool.

NOTE: The sample programs assume

that you have at least an elemen­tary grasp of ANSI C. If you do not,
see the introductory pages of the

Dynamic C Premier User’s Man­ual for a suggested reading list.

3–4 Software Installation & Overview RabbitCore RCM2200

Of the many sample programs included wi th
Dynamic C, several are specific to t he RCM2 200
module. These programs will be found i n the

Samples/RCM22 00 folder.

• FlashLEDs.c

• PingLED.c

• EthCore1.c

We suggest that you examine the fo llowing five of
these sample programs, in order, to get a complete
tour of the capabilities of the RabbitCor e RCM2200
modules. They form a “lea rning arc ” from basic I/ O
control to advanced TCP/IP issues, including web
serving:

• FlashLED.c

• ToggleLED.c

Each of these programs is fully commented within
the source code. Refer to these comments for the
details of how each program works.

Once you have loaded and executed these five pro­grams and have an understanding of how Dynamic C
and the RCM2200 modules interact, you can move
on and try the other sample programs, or begin build­ing your own.

4.1 TCP/IP Connections

Before proceeding you will need to have the follow­ing items.

• If you don’t have Ethernet acces s, you wi ll

need at leas t a 10Base-T Ethernet card
(available from your favorite computer
supplier) installed in a PC.

• Two RJ-45 straight through Ethernet

cables and a hub, or an RJ-45 crossover
Ethernet cable.

The Ethernet cables and Ethernet hub are available
from Z-World in a TCP/IP tool kit. More inf orm a­tion is available at www.zworld.com

1. Connect the AC adapter and the program-

ming cable as sho wn in Ch apte r 2, “Hard­ware Setup.”

2. Ethernet Connect ions

If you do not have access to an Ethernet
network, use a crossover Ethernet cable to
connect the RCM2200 board to a PC with
at least a 10Base-T Ethernet card.

.

If you have Ethernet access, use a straight
Ethernet cable to establish an Ethernet
connection to the RCM2200 from an Eth­ernet hub.

The PC running Dynamic C through the
serial port on the RCM2200 does not need
to be the PC w ith the Ethernet card.

3. Apply Power

Plug in the AC adapter. The RCM2200 is
now ready to be used.

4.2 Running TCP/IP Sample Programs

We have provided a number of sample pro grams
demonstrating various us es of TCP/IP f or network­ing embedded systems. These programs req uir e that
the user connect his PC and the RCM2200 board
together on the same network. This networ k can be
a local private network (pr eferred for initial experi­mentation and debugging), or a connection via the
Internet.

Direct Connection

(Network of 2 computers)

Obtaining IP addresses to interact over an existing,
operating, network can inv olve a number of compli­cations, and must usually be done with c ooper at ion
from your ISP and/or network syste ms admini stra­tor (if your company has one). For thi s re ason, it is
suggested that the user begi n instead by using a
direct connection between a PC a nd the RCM2200
board using an Ethernet crossover cable or a simple
arrangement with a hub. (A cro ssove r ca ble should
not be confused with regular s tr aight through
cables.) The hub and a wide variet y of cabl es c an
also be purchased from a local computer store.

both networks service the same I P addr ess , the n
Windows may send a packe t i ntended for your pri­vate network to the corporate network. A similar sit­uation will take place if you use a dial-up line to
send a packet to the Internet. Windows may try to
send it via the local Ether net network if it is also
valid for that network.

The following IP addresses are set asi de f or local
networks and are not allo we d on t he In ter n et :

10.0.0.0 to 10.255.255.255, 172.16.0.0 to

172.31.255.255, and 192.168.0.0 to

192.168.255.255.

In order to set up this dire ct connection, the us er will
have to use a virgin PC (r ight out of the box), or dis­connect a PC from the corporate network, or as yet
another approach insta ll a second Ethernet adapter
and set up a separat e priva te net work a ttache d to th e
second Ethernet adapter. Disconnecting your PC
from the corporate network may be e asy or nearly
impossible, depending on how it is set up. Mobil e
PCs, such as laptops, are designe d to be conne cted
and disconnected, and will present the least prob­lem. If your PC boots from the network or is depen­dent on the network for some or all of i ts disks, t hen
it probably should not be dis connected. If a second
Ethernet adapter is used, be aware that Windows
TCP/IP will send messages to one ada pter or t he
other, d ependi ng on the I P address and the binding
order in Microsoft products. Thus you should have
different ranges o f I P addresses on your private net­work from those used on the corporate network. If

The RCM2200 board uses a 10Base-T type of Eth­ernet connection, which is the most c ommon
scheme. The RJ-45 connectors are si mi la r t o U. S.
style telephone connect ors , are except larger and
have 8 contacts.

An alternative to the di rect c onnectio n using a cr oss­over cable is a direct conne ction using a hub. The
hub relays packets received on any port to all of the
ports on the hub. Hubs are low in cost and are
readily available. The RCM2200 board uses 10
Mbps Ethernet, so the hub or Etherne t ada pte r must
be either a 10 Mbps unit or a 10/100 unit th at a dapts
to either 10 or 100 Mbps.

In a corporate setting where the Internet is brought
in via a high-speed lin e, there are typi cally machines
between the outside Inte rnet and the internal net­work. These machines include a combination of
proxy servers and firewalls that filter and multiplex

RCM2200 board could be given a fixe d addr ess so
any of the computers on the local network would be
able to contact it. It ma y be possible t o configure t he

probably be easier to place the cont roller direc tly on

Each decimal number must be between 0 and 255.

used to identify the local network. The highest
address (216.102.126.255) is u sed a s a br oadc ast
address. Usually one other addr ess is us ed f or t h e
address of the gateway out of t he ne twork. This

leaves 256 - 3 = 253 available IP addresses for the
example given.

4.4 How IP Addresses are Used

The actual hardware connec tio n via an Ethernet
uses Ethernet adapter addre sses (also called MAC
addresses.) These are 48- bit addr ess es a nd are
unique for every Ethernet adapter manufactured. In
order to send a packet to anot her c omputer, given
the IP address of the other computer, it is f ir st d ete r­mined if the packet needs t o be sent dir ect ly to the
other computer or to the gatewa y. In either case,
there is an IP address o n the loca l network to which
the packet must be sent. A ta ble i s mai ntai ned to
allow the protocol driver to determine the MAC
address corresponding to a particular IP address. If
the table is empty, the MAC address is determined
by sending an Ethernet broadcast packet to all
devices on the local network asking the device with
the desired IP address to an swer wi th i ts MAC
address. In this way, the table entry can be filled in.
If no device answers, then the d evic e is nonexistent
or inoperative, and the packe t ca nnot be sent.

(If you want to find the IP addr ess assigned by a
dial-up ISP, run the program winipcfg while con­nected and look at the addr ess for the ppp adapter
under Windows 9 8.)

In a typical corporat e net work t hat is i solated from
the Internet by a firewall and/ or proxy server using
address translation , the I P addr ess es a re not usually
actual Internet addresses and may be assigned stati­cally or dynamically. If they are assigned statically,
you only have to get an unused IP addr ess and
assign it to the RCM2200 board. I f t he IP a ddre sse s
are assigned dynamically, they you will have to get
an IP address that is valid bu t outside of th e range of
IP addresses that are assi gned dynamically. This
will enable you to communicate from a PC on th e
network to the RCM2200 board. If you want t o
communicate to the RCM2200 board from t he
external Internet, then a n act ual Int erne t I P address
must be assigned to the RCM2200 board. It may be
possible to setup the fir ewall to pass a real IP
address, or it may be necess ary to co nnect the
RCM2200 board in front of the firewal l t o ac com­plish this.

IP addresses are arbitra ry and can be allocated as
desired provided that they don’t conflict with other
IP addresses. However, if they are to be used with
the Internet, then they must b e number s th at a re
assigned to your connection by proper authorities,
generally by delegation via your service provider.

4.5 Dynamically Assigned Internet Addresses

In many instances, IP addresses are assigned tempo­rarily. This the normal procedure wh en you u se a
dial-up Internet servi ce pr ovider (ISP). Your system
will be provided wit h an I P addres s that i t can use t o
send and receive packets . This IP address will only
be valid for the durati on of the call, and further may
not actually be a real Int ernet IP address. Such an
address works for browsing the Web, but cannot be
used for transactions ori ginating elsewhere since no
other system has any way to know the I nter net
address except by firs t re cei ving a packet from you.

4.6 How to Set IP Addresses in the Sample Programs

Most of the sample programs such as s hown in t he
example below use macros to define t he I P addr ess
assigned to the board and the I P addr ess of t he ga te­way , if there is a gateway.

#define MY_IP_ADDRESS
"216.112.116.155"

#define MY_NETMASK
"255.255.255.248"

#define MY_GATEWAY
"216.112.116.153"

In order to do a direct c onnec ti on the fol lowi ng IP
addresses can be used for the RCM2200 bo ard:

#define MY_IP_ADDRESS "10.1.1.2"
#define MY_NETMASK

"255.255.255.248"
// #define MY_GATEWAY

"216.112.116.153"

4–4 Using the TCP/IP Fe atures RabbitCore RCM2200

In this case, the gateway is n o t us ed and is c om­mented out. The IP address of the boa rd i s de fin ed
to be 10.1.1.2. The IP address of you PC can b e
defined as 10.1.1.1.

4.7 How to Set Up your Computer’s IP Address For Direct Co nnect

When your computer is connected directly to the
RCM2200 board via an Ethernet connecti on, you
need to assign an IP address t o your computer. To
assign the PC the address 10 .1.1.1 wit h t he sub net­mask 255.255.255.248 under Windows 98, do the
following.

IP 10.1.1.1
Subnet mask

255.255.255.248

Click on St art > Settings > Control Panel to
bring up the Control Panel, and t hen dou ble- cl ick
the Network icon. In the window find the li ne of the
form TCP/IP > Ethernet adapter name. Dou­ble-click on this line t o bri ng up t he TCP/ IP pr oper ­ties dialog box. You can edit the IP address directly
and the subnet mask. (Disable “obtain an IP address
automatically.”) You may want to write down the
existing values in cas e you ha ve t o res tor e t hem
later. It is not necessary to edit the gateway address
since the gateway is not u sed wi th di rec t c onnect .

The method of setting the IP address may differ for
different versions of Windows, such as 95, NT or

2000.

The programs STATIC.C and SSI3.C (SAM-
PLES\TCPIP\HTTP) demonstrate how to make

the RCM2200 board be a Web server. This program
allows you to turn the LEDs on an attached Demon­stration Board from the Devel opment Kit on and off
from a remote Web browser. In order to run these
sample programs, edit the IP addr ess as f or t he
