RabbitCore RCM3305/RCM3315

User’s Manual 1
1. INTRODUCTION
The RCM3305 and RCM3315 RabbitCore modules feature a
compact module that incorporates the latest revision of the power-
ful Rabbit®3000 microprocessor, flash memory, mass storage
(serial flash), static RAM, and digital I/O ports. The RCM3305
and RCM3315 feature an integrated 10/100Base-T Ethernet port,
and provide for LAN and Internet-enabled systems to be built as
easily as serial-communication systems.
In addition to the features already mentioned above, the RCM3305 and RCM3315 have
two clocks (main oscillator and real-time clock), reset circuitry, and the circuitry necessary
for management of battery backup of the Rabbit 3000’s internal real-time clock and the
static RAM. Two 34-pin headers bring out the Rabbit 3000 I/O bus lines, parallel ports,
and serial ports.
The RCM3305’s and the RCM3315’s mass-storage capabilities make them suited to running
the optional Dynamic C FAT file system module and the featured remote application
update where data are stored and handled using the same directory file structure com-
monly used on PCs.
The RCM3305 or RCM3315 receives +3.3 V power from the customer-supplied mother-
board on which it is mounted. The RCM3305 and RCM3315 can interface with all kinds
of CMOS-compatible digital devices through the motherboard.
The Development Kit has what you need to design your own microprocessor-based
system: a complete Dynamic C software development system and a Prototyping Board
that allows you to evaluate the RCM3305 or RCM3315, and to prototype circuits that
interface to the RCM3305 or RCM3315 module.

2RabbitCore RCM3305/RCM3315
1.1 RCM3305/RCM3315 Features

•Supports 1.15 Mbps IrDA transceiver
The RCM3900/RCM3910 and RCM3365/RCM3375 RabbitCore modules are similar to
the RCM3305/RCM3315 and RCM3309/RCM3319, but they use fixed NAND or remov-
able media for their mass-storage memories instead of the fixed serial flash options of the
RCM3305/RCM3315 and the RCM3309/RCM3319.

User’s Manual 3
Table 1 below summarizes the main features of the RCM3305 and the RCM3315 modules.
The RCM3305 and RCM3315 are programmed over a standard PC serial port through a
programming cable supplied with the Development Kit, and can also be programed through
a USB port with an RS-232/USB converter, or directly over an Ethernet link using the fea-
tured remote application update or the Dynamic C download manager with or without a
RabbitLink.
Appendix A provides detailed specifications for the RCM3305 and the RCM3315.

1.2 Comparing the RCM3309/RCM3319 and RCM3305/RCM3315
We can no longer obtain certain components for the RCM3305/RCM3315 RabbitCore
modules that support the originally specified -40°C to +70°C temperature range. Instead of
changing the design of the RCM3305/RCM3315 RabbitCore modules to handle available
components specified for the original temperature range, we decided to develop a new
product line — the RCM3309/RCM3319 — based on the RCM3900 RabbitCore modules
that were released for the same reason.
The RCM3309/RCM3319 modules are similar in form, dimensions, and function to the
RCM3305/RCM3315 modules. We strongly recommend that existing RCM3305/3315
customers and designers of new systems consider using the new RCM3309/RCM3319
RabbitCore modules.
This section compares the two lines of RabbitCore modules.
•Temperature Specifications — RCM3305/RCM3315 RabbitCore modules manufac-
tured after May,2008, are specified to operate at 0°C to +70°C. The RCM3309/
RCM3319, rated for -40°C to +85°C, are offered to customers requiring a larger
temperature range after May,2008.
•Maximum Current — The RCM3305/RCM3315 draws 390 mA vs. the 325 mA
required by the RCM3309/RCM3319.
•LEDs — The SPEED and user (USR/BSY)LED locations have been swapped between
the RCM3305/RCM3315 and the RCM3309/RCM3319, the LNK/ACT LEDs have been
combined to one LED on the RCM3309/RCM3319, and the RCM3309/RCM3319 has
an FDX/COL LED instead of the SF LED on the RCM3305/RCM3315. The SF LED
on the RCM3305/RCM3315 blinks when data are being written to or read from the
serial flash. The FDX/COL LED on the RCM3309/RCM3319 indicates whether the
Ethernet connection is in full-duplex mode (steady on) or that a half-duplex connection
is experiencing collisions (blinks).
NOTE: The change in LED indicators means that there is no indication on the
RCM3309/RCM3319 when data are being written to or read from the serial flash.
•Ethernet chip. A different Ethernet controller chip is used on the RCM3309/RCM3319.
The Ethernet chip is able to detect automatically whether a crossover cable or a straight-
through cable is being used in a particular setup, and will configure the signals on the
Ethernet jack interface.
•Dynamic C — As long as no low-level FAT file system calls were used in your applica-
tion developed for the RCM3305/RCM3315, you may run that application on the
RCM3309/RCM3319 after you recompile it using Dynamic C v. 9.60.

User’s Manual 5
1.3 Advantages of the RCM3305 and RCM3315

2. GETTING STARTED
This chapter describes how to set up and use an RCM3305 series
module and the Prototyping Board included in the Development Kit.
NOTE: It is assumed that you have a Development Kit. If you purchased an RCM3305
series module by itself, you will have to adapt the information in this chapter and else-
where to your test and development setup.
2.1 Install Dynamic C
To develop and debug programs for an RCM3305 series module (and for all other Rabbit
hardware), you must install and use Dynamic C.
If you have not yet installed Dynamic C version 9.25 (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 otherwise 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 communicate with the target development system.
The installation allows you to choose the COM port that will be used. The default selec-
tion is COM1. You may select any available port for Dynamic C’s use. If you are not cer-
tain 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 use by another device (mouse, modem, etc.) may lead to 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 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 the optional Dynamic C Rabbit Embedded Security Pack, install it
after installing Dynamic C. You must install the Rabbit Embedded Security Pack in the
same directory where Dynamic C was installed.

10 RabbitCore RCM3305/RCM3315
2.2 Hardware Connections
There are three steps to connecting the Prototyping Board for use with Dynamic C and the
sample programs:
1. Attach the RCM3305 series RabbitCore module to the Prototyping Board.
2. Connect the programming cable between the RCM3305 series RabbitCore module and
the workstation PC.
3. Connect the power supply to the Prototyping Board.
2.2.1 Step 1 — Attach Module to Prototyping Board
Turn the RCM3305 series module so that the Ethernet jack is facing the direction shown in
Figure 2 below. Align the pins from the headers on the bottom side of the module into
header sockets JA and JB on the Prototyping Board.
Figure 2. Install the RCM3305/ Series Module on the Prototyping Board
NOTE: It is important that you line up the pins from the headers on the bottom side of the
RCM3305 series module exactly with the corresponding pins of header sockets JA and
JB 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 electrical damage to the
module may also result if a misaligned module is powered up.
Press the module’s pins firmly into the Prototyping Board header sockets—press down in
the area above the header pins using your thumbs or fingers over the connectors as shown
in Figure 2. Do not press down on the middle of the RCM3305 series module to avoid
flexing the module, which could damage the module or the components on the module.
Should you need to remove the RCM3305 series module, grasp it with your fingers along the
sides by the connectors and gently work the module up to pull the pins away from the sockets
where they are installed. Do not remove the module by grasping it at the top and bottom.

nonprogramming serial connection.)
Figure 3(b). Connect Programming Cable and Power Supply
NOTE: Be sure to use the serial programming cable (part number 101-0542)—the pro-
gramming cable has blue shrink wrap around the RS-232 converter section located in the
middle of the cable. The USB programming cable and programming cables with clear or
red shrink wrap from other Rabbit kits are not designed to work with RCM3305/
RCM3315 modules.
Connect the other end of the programming cable to a COM port on your PC.
NOTE: It may be possible to use an RS-232/USB converter with the serial programming
described in this section. An RS-232/USB converter (part number 20-151-0178) is
available through the Web store. Note that not all RS-232/USB converters work with
Dynamic C.

If you have the universal power supply, prepare the AC adapter for the country where it
will be used by selecting the plug. The RCM3305 Series Development 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 3(a),
then press down on the spring-loaded clip below the plug assembly to allow the plug
assembly to click into place.
Depending on the style of adapter, connect the AC adapter to 3-pin header J2 or jack J1 on
the Prototyping Board as shown in Figure 3(a) or Figure 3(b).
Plug in the AC adapter. The red CORE LED on the Prototyping Board should light up.
The RCM3305 series RabbitCore module and the Prototyping Board are now ready to be
used.
NOTE: A RESET button is provided on the Prototyping Board to allow a hardware reset
without disconnecting power.
2.2.3.1 Alternate Power-Supply Connections
All Development Kits sold up to May, 2008, included a header connector that may be used
to connect your power supply to 3-pin header J2 on the Prototyping Board. The connector
may be attached either way as long as it is not offset to one side—the center pin of J2 is
always connected to the positive terminal, and either edge pin is negative. The power
supply should deliver 8 V to 30 V DC at 8 W.

2.3 Starting Dynamic C
NOTE: Dynamic C v. 9.60 or a later version is required if you are using an RCM3309 or
an RCM3319 RabbitCore module.
Once the RCM3305 series module is connected as described in the preceding pages, start
Dynamic C by double-clicking on the Dynamic C icon on your desktop or in your Start
menu. Select Code and BIOS in Flash, Run in RAM on the “Compiler” tab in the
Dynamic C Options > Project Options menu. Click OK.
If you are using a USB port to connect your computer to the RCM3305/RCM3315 module,
choose Options > Project Options and select “Use USB to Serial Converter” on the
Communications tab. Click OK.
2.4 Run 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 win-
dow 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 6.5, “Run the PINGME.C Sample Program,” tests the TCP/IP portion of the board.
2.4.1 Troubleshooting
If Dynamic C cannot find the target system (error message "No Rabbit Processor
Detected."):
•Check that the RCM3305 series module is powered correctly — the red CORE LED on
the Prototyping Board should be lit when the module is mounted on the Prototyping Board and
the AC adapter is plugged in.
•Check both ends of the programming cable to ensure that they are firmly plugged into
the PC and the PROG connector, not the DIAG connector, is plugged in to the program-
ming port on the RCM3305 series module with the marked (colored) edge of the pro-
gramming cable towards pin 1 of the programming header.
•Ensure that the RCM3305 series module is firmly and correctly installed in its connec-
tors on the Prototyping Board.
•Dynamic C uses the COM port or USB port specified during installation. Select a dif-
ferent COM port within Dynamic C. From the Options menu, select Project Options,
then 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 COM
port used by the programming cable.
•If you get an error message when you plugged the programming cable into a USB port,
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 sys-
tems are available online at www.ftdichip.com/Drivers/VCP.htm.
