Installing and Running Dynamic C
Once the RCM3700 is connected and Dynamic C is installed as described in the preceding pages, start
Dynamic C by double-clicking on the Dynamic C icon or by double-clicking on dcrab_XXXX.exe in
the Dynamic C root directory, where XXXX are version-specific characters. Dynamic C uses the serial port
specified during installation.
If you are using a USB port to connect your computer to the RCM3700 module, choose Options >
Project Options and select “Use USB to Serial Converter” under the Communications tab.
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 window will open on your PC and will
display a small square bouncing around in a box.
Troubleshooting
If Dynamic C cannot find the target system (error message "No Rabbit Processor Detected."):
• Check that the RCM3750 is powered correctly — the power LED above the RESET button on the
Prototyping Board should be lit.
• Check to make sure you are using the PROG connector, not the DIAG connector, on the programming
cable.
• Check both ends of the programming cable to ensure that they are firmly plugged into the PC and the
programming port on the RCM3750.
• Ensure that the RCM3750 module is firmly and correctly installed in its connector on the Prototyping
Board.
• Select a different 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 sys-
tem, repeat the above steps until you locate the active COM port.
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.
• Locate the “Serial Options” dialog in the Dynamic C Options > Project Options > Communica-
tions menu. Choose a lower debug baud rate.
If there are any other problems:
• Use the Dynamic C Help menu to get further assistance with Dynamic C.
• Check the Rabbit Semiconductor Technical Bulletin Board at www.rabbit.com/support/bb/.
• Use the Technical Support e-mail form at www.rabbit.com/support/questionSubmit.shtml.
NOTE: If you purchased your RCM3700 through a distributor or through a Rabbit Semiconductor
partner, contact the distributor or partner first for technical support.
Where Do I Go From Here?
If the sample program ran fine, you are now ready to go on to other sample programs on the supplementary
CD-ROM and to develop your own applications. The source code for the sample programs is provided to
allow you to modify them for your own use. Application Note AN406, Will That Be Serial or Ethernet?,
describes the software and sample programs for this Application Kit, and is available on the supplementary
CD-ROM.
Installing Dynamic C
®
Insert the Dynamic C CD from the Application Kit in your PC’s CD-ROM drive.
If the installation does not auto-start, run the
setup.exe program in the root
directory of the Dynamic C CD.
Install any Dynamic C modules and the software
from the supplemental CD after you install Dynamic C.
Hardware Connections
1. Attach Module to Prototyping Board
Turn the RCM3700 module so that the Ethernet jack is on the left as shown in Figure 1 below. Insert
the module’s J1 header into the TCM_SMT_SOCKET socket on the Prototyping Board. The shaded
corner at the bottom right corner of the RCM3700 module should face the same direction as the corre-
sponding shaded corner below it on the Prototyping Board.
Figure 1. Install the RCM3700 Module on the Prototyping Board
NOTE: It is important that you line up the pins on header J1 of the RCM3700 module exactly
with the corresponding holes of the TCM_SMT_SOCKET socket 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 socket.
2. Connect Programming Cable
The programming cable connects the RCM3700 to the PC running Dynamic C to download programs
and to monitor the RCM3700 module during debugging.
Connect the 10-pin connector of the programming cable labeled
PROG to header J2 on the RCM3700
as shown in Figure 1. 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.)
Connect the other end of the programming cable to a COM port on your PC.

NOTE: Be sure to use the programming cable supplied with this Application Kit—the program-
ming cable has blue shrink wrap around the RS-232 converter section located in the middle of
the cable. Programming cables from other Z-World or Rabbit Semiconductor kits were not
designed to work with RCM3700 modules.
NOTE: Some PCs now come equipped only with a USB port. It may be possible to use an
RS-232/USB converter with the programming cable supplied with the RCM3700 series
Development Kit. An RS-232/USB converter is available through the Z-World Web store.
3. Connect Power
When all other connections have been made, you can connect power to the Prototyping Board.
Connect the wall transformer to 3-pin header J4 on the Prototyping Board as shown in Figure 1.
The
connector may be attached either way as long as it is not offset to one side.
Plug in the wall transformer. The LED above the RESET button on the Prototyping Board should
light up. The RCM3700 and the Prototyping Board are now ready to be used.
NOTE: The RESET button is provided on the Prototyping Board to allow a hardware reset with-
out disconnecting power.
Overseas Development Kits
Development kits sold outside North America include a header connector that may be connected to 3-
pin header J4 on the Prototyping Board. The red and black wires from the connector can then be con-
nected to the positive and negative connections on your power supply. The power supply should deliver
7.5 V–30 V DC at 500 mA.
4. Attach Other Cables and Jumpers
Use the Ethernet crossover
cable to connect the RJ-45
jack on the RCM3700 to
the RJ-45 jack on your PC.
Depending on the sample
program and how you run
it, you will then either
attach one or more jump-
ers across pins on header
J2 of the RCM3700 Proto-
typing Board, or you will
use one of the cables with
a 10-pin header and a DE9
connector to connect
header J2 to either a PC or
to the QK145 temperature
sensor.
Additional Hardware Information
The RabbitCore RCM3700 User’s Manual on the Dynamic C CD-ROM provides complete informa-
tion on using and developing applications for the RCM3700, and includes further information on the
Prototyping Board and
an optional LCD/keypad module.

NOTE: Be sure to use the programming cable supplied with this Application Kit—the program-
ming cable has blue shrink wrap around the RS-232 converter section located in the middle of
the cable. Programming cables from other Rabbit Semiconductor kits are not designed to work
with RCM3700 modules.
NOTE: Some PCs now come equipped only with a USB port. It may be possible to use an
RS-232/USB converter (Part No. 540-0070) with the programming cable supplied with the
Application Kit. Note that not all RS-232/USB converters work with Dynamic C.
Connect Power
When all other connections have been made, you can connect power to the Prototyping Board.
Connect the wall transformer to 3-pin header J4 on the Prototyping Board as shown in Figure 1.
The
connector may be attached either way as long as it is not offset to one side.
Plug in the wall transformer. The LED above the RESET button on the Prototyping Board should
light up. The RCM3700 and the Prototyping Board are now ready to be used.
NOTE: The RESET button is provided on the Prototyping Board to allow a hardware reset with-
out disconnecting power.
Overseas Development Kits
Development kits sold outside North America include a header connector that may be connected to 3-
pin header J4 on the Prototyping Board. The red and black wires from the connector can then be con-
nected to the positive and negative connections on your power supply. The power supply should deliver
7.5 V–30 V DC at 500 mA.
Attach Other Cables and Jumpers
Use the Ethernet crossover
cable to connect the RJ-45
jack on the RCM3700 to
the RJ-45 jack on your PC.
Depending on the sample
program and how you run
it, you will then either
attach one or more jump-
ers across pins on header
J2 of the RCM3700 Proto-
typing Board, or you will
use one of the cables with
a 10-pin header and a DE9
connector to connect
header J2 to either a PC or
to the QK145 temperature
sensor.
Additional Hardware Information
The RabbitCore RCM3700 User’s Manual on the Dynamic C CD-ROM provides complete informa-
tion on using and developing applications for the RCM3700, and includes further information on the
Prototyping Board and
an optional LCD/keypad module.

Installing and Running Dynamic C
Once the RCM3700 is connected and Dynamic C is installed as described in the preceding pages, start
Dynamic C by double-clicking on the Dynamic C icon or by double-clicking on dcrab_XXXX.exe in
the Dynamic C root directory, where XXXX are version-specific characters. Dynamic C uses the serial port
specified during installation.
If you are using a USB port to connect your computer to the RCM3700 module, choose Options >
Project Options and select “Use USB to Serial Converter” under the Communications tab.
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 window will open on your PC and will
display a small square bouncing around in a box.
Troubleshooting
If Dynamic C cannot find the target system (error message "No Rabbit Processor Detected."):
• Check that the RCM3750 is powered correctly — the power LED above the RESET button on the
Prototyping Board should be lit.
• Check to make sure you are using the PROG connector, not the DIAG connector, on the programming
cable.
• Check both ends of the programming cable to ensure that they are firmly plugged into the PC and the
programming port on the RCM3750.
• Ensure that the RCM3750 module is firmly and correctly installed in its connector on the Prototyping
Board.
• Select a different 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 sys-
tem, repeat the above steps until you locate the active COM port.
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.
• Locate the “Serial Options” dialog in the Dynamic C Options > Project Options > Communica-
tions menu. Choose a lower debug baud rate.
If there are any other problems:
• Use the Dynamic C Help menu to get further assistance with Dynamic C.
• Check the Rabbit Semiconductor Technical Bulletin Board at www.rabbit.com/support/bb/.
• Use the Technical Support e-mail form at www.rabbit.com/support/questionSubmit.shtml.
NOTE: If you purchased your RCM3700 through a distributor or through a Rabbit Semiconductor
partner, contact the distributor or partner first for technical support.
Where Do I Go From Here?
If the sample program ran fine, you are now ready to go on to other sample programs on the supplementary
CD-ROM and to develop your own applications. The source code for the sample programs is provided to
allow you to modify them for your own use. Application Note AN406, Will That Be Serial or Ethernet?,
describes the software and sample programs for this Application Kit, and is available on the supplementary
CD-ROM.
Installing Dynamic C
®
Insert the Dynamic C CD from the Application Kit in your PC’s CD-ROM drive.
If the installation does not auto-start, run the
setup.exe program in the root
directory of the Dynamic C CD.
Install any Dynamic C modules and the software
from the supplemental CD after you install Dynamic C.
