OEM User’s Manual 5
1.4 Certifications
The systems integrator and the end-user are ultimately responsible for the channel range
and power limits complying with the regulator y requirements of the co untry 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, 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.
1.4.1 FCC Part 15 Class B
The RCM5400W RabbitCore module has been tested and found to comply with the l imits

2. GETTING S TARTED
This chapter describes the RC M540 0W hardw are i n m ore detai l, a nd
explains how to set up and use the accompanying Prototyping Board.
NOTE: This chapter (and this manual) assume that you have the RCM5400W Develop-
ment Kit. If you purchased an RCM5400W or RCM5450W module by itself, you will
have to adapt the information in this chapter and elsewhere to your test and development setup.
2.1 Install Dynamic C
To develop and debug programs for the RCM5400W series of modules (and for all other
Rabbit Semiconductor hardware), you must install and use Dynamic C.
If you have not yet installed Dynamic C version 10.40 (or a later version), do so now by
inserting the Dynamic C CD from the Development 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.
Dynamic C uses a COM (serial ) port to communica te with the tar get deve lopment sy stem.
The installation allows you to choose the COM port that will be used. The default selection is COM1. You may select any available port for Dynamic C’s use. If you are not certain which port is available, select COM1. This selection can be changed later within
Dynamic C.
NOTE: The installation utility does not check the selected COM port in any way. Speci-
fying a port in u se by a not her device (mouse, modem, et c.) may l ea d t o a message such
as
"could not open serial port" when Dynamic C is started.
Once your installation is complete, you will have up to three new icons on your PC desktop. One icon is for Dynamic C, another 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.
OEM User’s Manual 9
2.2 Hardware Connections
There are three steps to connecting the Prototyping Board for use with Dynamic C and the
sample programs:
1. Prepare the Prototyping Board for Development.
2. Attach the antenna to the RCM5400W module.
3. Attach the RCM5400W module to the Prototyping Board.
4. Connect the programming cable between the RCM5400W and the PC.
5. Connect the power supply to the Prototyping Board.
CAUTION: Provide ESD protection such as smocks and grounding straps on your
footwear.while assembling the RCM5400W module, installing it on another
board, and while making or removing any connections.
Remember to use ESD protection re gardl ess of whet her you are worki ng with th e
RCM5400W module on the Prototyping Board or in your own OEM application.
2.2.1 Step 1 — Prepare the Prototyping Board for Development
Snap in four of the plastic standoffs supplied in the bag of accessory parts from the Development Kit in the holes at the corners as shown in Figure 2.
NOTE: Be sure to use the hole th at is point ed ou t toward s the bot tom left of the Pr ototyp -
ing Board since the hol e below it is used f or a stan doff when mounting the RCM5400W
on the Prototyping Board.

Figure 4. Install the Module on the Prototyping Board
NOTE: It is important that you line up the pins on header J1 of the module exactly with
socket RCM1 on the Pr ototyp ing Boa rd. The header pins may bec ome bent or da maged
if the pin alignment is offset, and the module will not work. Permanent electrical damage to the module may also result if a misaligned module is powered up.
Press the module’s pins gently into the Prototyping Board socket—press down in the area
above the header pins. For additional integrity, you may secure the RCM5400W to the
standoffs from the top using the remaining three screws and washers.

2.2.4 Step 4 — Connect Programming Cable
The programming cable connects the module to the PC running Dynamic C to download
programs and to monitor the module during debugging.
Connect the 10-pin connector of the programming cable labeled
PROG to header J2 on
the RCM5400W as shown in Figure 5. Be sure to orient the marked (usually red) edge of
the cable towards pin 1 of the connector. (Do not use the DIAG connector, which is used
for a normal serial connection.)

Figure 5. Connect Programming Cable and Power Supply
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 dr i ve rs . 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.

2.2.5 Step 5 — Connect Power
Once all the other connections have been made, you can connect power to the Prototyping
Board.
If you have the universal AC adapter, p repare the AC adapter for the country where it will
be used by selecti n g th e a pp ro p ri at e p lu g . Snap in the top of the plug assembly into the slot
at the top of the AC adapter as shown in Figure 5, then press down on the plug until it
clicks into place.
Connect the AC adapter to 3-pin header J1 on the Prototyping Board as shown in Figure 5
above. The connector may be attached either way as long as it is not offset to one side—
the center pin of J1 is always connected to the positive terminal, and either edge pin is
ground.
Plug in the AC adapter. The
PWR LED on the Prototyping Board next to the power con-
nector at J1 should light up. The RCM5400W and the Prototyping Board are now ready to
be used.
NOTE: A RESET button is provided on the Pro totyping Bo ard next t o the batt ery holder
to allow a hardware reset without disconnecting power.
14 RabbitCore RCM5400W
2.3 Run a Sample Program
If you already have Dynamic C installed, you are now ready to test your programming
connections by running a sample program. 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 menu. Then click
on the “Communications” tab and verify that Use USB to Serial Converter 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.
Now find the WIFISCAN.C sample program in the Dynamic C Samples\WiFi folder,
open it with the File menu, then compile and run the sample program by pressing F9.
The Dynamic C STDIO window will display Starting scan...., and will display a list
of access points/ad-hoc hosts as shown here.
The following fields are shown in the Dynamic C STDIO window.
• Channel—the channel the access point is on (1–11).
• Signal—the signal strength of the access point.
• MAC—the hardware (MAC) address of access point.
• Access Point SSID—the SSID the access point is using.

If you receive the message Could Not Open Serial Port, check that the COM port
assigned to the USB programming cable was identified and set up in Dynamic C as
described in the preceding section.
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 tar get
system may not be powered up. First, check to see that the power LED on the Prototyping
Board is lit. If the LED is lit, ch eck both ends of the programm ing cable to ensure tha t it is
firmly plugged into the PC and the programming header on the RCM5400W 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
Prototyping 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 Opti ons 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 Serial Options dialog on the “Communications” tab in the Dynamic C
Options > Project Options menu. Choose a lower debug baud rate. Click OK to save.
Press <Ctrl-Y> to force Dyn a m i c C to re compile th e B I O S . You should receive a Bios
compiled successfully
message once this step is completed successfully.

3. RUNNING SAMPLE PROGRAMS
To develop and debug programs for the RCM5400W (and for all
other Rabbit hardware), you must install and use Dynamic C.
This chapter provides a tour of its m ajor features with respect to
the RCM5400W modules.
3.1 Introduction
To help familiarize you with the RCM5400W modules, Dynamic C includes several sample programs. Loading, executing and studying these programs will give you a solid
hands-on overview of the RCM5400W’s capabilities, as well as a quick start with
Dynamic C as an application development tool.
This chapter provides sam ple programs t hat illust rate the digital I/O and s erial capabil ities
of the RCM5400W RabbitCore module. Section 6.2.4 discusses the sample programs that
illustrate the Wi-Fi features.
NOTE:
In order to run the sample programs discussed in this chapter and elsewhere in this manual,
1. Your module must be plugged in to the Prototyping Board as described in Chapter 2,
“Getting Started.”
2. Dynamic C must be installed and running on your PC.
3. The programming cable must connect the programming header on the module to your
PC.
4. Power must be applied to the module through the Prototyping Board.
Refer to Chapter 2, “Getting Started,” if you need further information on these steps.
To run a sample program, open it with the File menu, then compile and run it by pressing
F9.
Each sample program has comments that describe the purpose and function of the program. Follow the instructions at the beginning of the sample program.
Complete information on Dynamic C is provided in the Dynamic C User’s Manual.

3.2 Sample Programs
Of the many sample programs included with Dynamic C, several are specific to the
RCM5400W modules. These programs will be found in the SAMPLES\RCM5400W folder.
• CONTROLLED.C—Demonstrates use of the digital outputs by having you turn LEDs
DS2 and DS3 on the Prototyping Board on or off from the STDIO window on your PC.
Parallel Port B bit 2 = LED DS2
Parallel Port B bit 3 = LED DS3
Once you compile and run CONTROLLED.C, the following display will appear in the
Dynamic C STDIO window.
Press “2” or “3” on your keyboard to select LED DS2 or DS3 on the Prototyping
Board. Then follow the prompt in the Dynamic C STDIO window to turn the LED ON
or OFF. A logic low will light up the LED you selected.
• FLASHLED1.C—demonstrates the use of assembly language to flash LEDs DS2 and
DS3 on the Prototyping Board at different rates. Once you have compiled and run this
program, LEDs DS2 and DS3 will flash on/off at different rates.
• FLASHLED2.C—demonstrates the use of cofunctions and costatements to flash LEDs
DS2 and DS3 on the Prototyping Board at different rates. Once you have compiled and
run this program, LEDs DS2 and DS3 will flash on/off at different rates.
20 RabbitCore RCM5400W
• TAMPERDETECTION.C—demonstrates how to detect an attempt to enter the bootstrap
mode. When an attempt is detected, the battery-backed onchip-encryption RAM on the
Rabbit 5000 is erased. This battery-backed onchip-encryption RAM can be useful to
store data such as an AES encryption key from a remote location.
This sample program shows how to load and read the battery-backed onchip-encryption
RAM and how to enable a visual indicator.
Once this sample is compiled and running (you pressed the
F9 key while the sample
program is open), remove the programming cable and press the reset button on the
Prototyping Board to reset the module. LEDs DS2 and DS3 will be flashing on and off.
Now press switch S2 to load the battery-backed RAM with the encryption key. The
LEDs are now on continuously. Notice that the LEDs will stay on even when you press
the reset button on the Prototyping Board.
Reconnect the programming cable briefly and unplug it again to simulate an attempt to
access the onchip-encryption RAM. The LEDs will be flashing because the batterybacked onchip-encryption RAM has been erased. Notice that the LEDs will continue
flashing even when you press the reset button on the Prototyping Board.
You may press switch S2 again and repeat the last steps to watch the LEDs.
• TOGGLESWITCH.C—demonstrates the use of costatements to detect switch presses
using the press-and-release method of debouncing. LEDs DS2 and DS3 on the Prototyping Board are turned on and off when you press switches S2 and S3. S2 and S3 are
controlled by PB4 and PB5 respectively.
Once you have loaded and executed these five programs and have an understanding of
how Dynamic C and the RCM5400W modules interact, you can move on and try the other
sample programs, or begin building your own.
OEM User’s Manual 21
3.2.1 Use of Serial Flash
The following sample programs can be found in the SAMPLES\RCM5400W\Serial_Flash
folder.
• SERIAL_FLASHLOG.C—This program runs a simple Web server and stores a log of
hits on the home page of the serial flash “server.” This log can be viewed and cleared
from a browser at http://10.10.6.100/. You will likely have to first “configure” your network interface card for a “10Base-T Half-Duplex,” “100Base-T Half-Duplex,” or an
“Auto-Negotiation” connection on the “Advanced” tab, which is accessed from the
control panel (
Connections
Start > Settings > Control Panel) by choosing Network
.
• SFLASH_INSPECT.C—This program is a handy utility for inspect ing the contents of a
serial flash chip. When the sample program starts running, it attempts to initialize a
serial flash chip on Serial Port B. Once a serial flash chip is found, the user can perform
five different commands to print out the contents of a specified page, set all bytes on
the specified page to a single random value, clear (set to zero) all the bytes in a specified page, set all bytes on the specified page to a given value, or save user-specified text
to a selected page.

3.2.2 Serial Communication
The following sample programs are found in the SAMPLES\RCM5400W\SERIAL folder.
FLOWCONTROL.C—This program demonstrates how to configure Serial Port D for
•
CTS/R TS flow control with serial data coming from Serial Port C (TxC) at 1 15, 200 bps .
The serial data received are displayed in the STDIO window.
To set up the Prototyping Board, you will need to tie TxD and RxD
together on the RS-232 header at J4, and you will also tie TxC and
RxC together using the jumpers supplied in the Development Kit as
RxC TxC
TxD RxD
GND
shown in the diagram.
A repeating triangular pattern should print out in the STDIO window.
The program will periodically switch flow contr ol on or off to demonstrate th e eff ect of
flow control.
If you have two Prototyping Boards with modules, run this sample program on the
sending board, then disconnect the programming cable and reset the sending board so
that the module is operating in the Run mode. Connect TxC, TxD, and GND on the
sending board to RxC, RxD, and GND on the other board, then, with the programming
cable attached to the other module, run the sample program.
• PARITY.C—This program demonstrates the use of parity modes by
RxC
TxD
TxC
RxD GND
repeatedly sending byte values 0–127 from Serial Port C to Serial Port D.
The program will switch between generating parity or not on Serial
Port C. Serial Port D will always be checking parity, so parity errors
should occur during every other sequence.
J4
J4
To set up the Prototyping Board, you will need to tie TxC and RxD together on the
RS-232 header at J4 using one of the jumpers supplied in the Development Kit as
shown in the diagram.
The Dynamic C STDIO window will display the error sequence.
• SERDMA.C—This program demonstrates using DMA to transfer data from a circ ular
buffer to the serial port and vice versa. The Dynamic C
STDIO window is used to view or
clear the buffer.
Before you compile and run the sample program, you
will need to connect the RS-232 he ade r a t J4 to y our PC
as shown in the diagram using the serial to DB9 cable
supplied in the Development Kit.
Colored
edge
Once you have compiled and run the sample program,
start Tera Term or another terminal emulation program
to connect to the selected PC serial port at a baud rate of
115,200 bps. You can observe the output in the Dynamic C
STDIO window as you type in T e ra Term, and you can
also use the Dynamic C STDIO window to clear the
buffer.

• SIMPLE3WIRE.C—This program demonstrates basic RS-232 serial
communication. Lower case characters are sent on TxC, and are
received by RxD. The received characters are converted to upper case
and are sent out on TxD, are received on RxC, and are displayed in the
Dynamic C
STDIO window.
RxC TxC
TxD RxD
J4
GND
To set up the Prototyping Board, you will need to tie TxD and RxC together on the
RS-232 header at J4, and you will also tie RxD and TxC together using the jumpers
supplied in the Development Kit as shown in the diagram.
• SIMPLE5WIRE.C—This program demonstrates 5-wire RS-232 serial communication
with flow control on Serial Port D and data flow on Serial Port C.
To set up the Prototyping Board, you will need to tie TxD and RxD
together on the RS-232 header at J4, and you will also tie TxC and
RxC together using the jumpers supplied in the Development Kit as
RxC TxC
TxD RxD
J4
GND
shown in the diagram.
Once you have compiled and run this program, you can test flow con-
trol by disconnecting the TxD jumper from RxD while the program is running. Characters will no longer appear in the STDIO window, and will display again once TxD is
connected back to RxD.
If you have two Prototyping Boards with modules, run this sample program on the
sending board, then disconnect the programming cable and reset the sending board so
that the module is operating in the Run mode. Connect TxC, TxD, and GND on the
sending board to RxC, RxD, and GND on the other board, then, with the programming
cable attached to the other module, run the sample program. Once you have compiled
and run this program, you can test flow control by disconnecting TxD from RxD as
before while the program is running. Since the J4 header locations on the two Prototyping
Boards are connected with wires, there are no slip-on jumpers at J4 on either Pr ototyping
Board.
• SWITCHCHAR.C—This program demonstrates transmitting and then receiving an
ASCII string on Serial Ports C and D. It also displays the serial data received from both
ports in the STDIO window.
To set up the Prototyping Board, you will need to tie TxD and RxC
together on the RS-232 header at J4, and you will also tie RxD and
TxC together using the jumpers supplied in the Development Kit as
shown in the diagram.
RxC TxC
TxD RxD
J4
GND
Once you have compiled and run this program, press and release
switches S2 and S3 on the Prototyping Board. The data sent between the serial ports
will be displayed in the STDIO window.
