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 RCM5600W 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. 10.50 or later. The certification is valid only for RCM5600W 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). Follow the antenna grounding recommendations provided in Section 4.3.1. 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 RCM5600W
module is removed.

2. GETTING S TARTED

This chapter describes the RC M560 0W hardw are i n m ore detai l, a nd explains how to set up and use the accompanying Interface Board.
NOTE: This chapter (and this manual) assume that you have the RCM5600W Develop-
ment Kit. If you purchased an RCM5600W module by it self , you will hav e to adapt the information in this chapter and elsewhere to your test and development setup.

2.1 Install Dynamic C

To develop and de bu g pro gr am s for the RC M560 0W mod ul es (and for al l oth e r Rabb i t hardware), you must install and use Dynamic C.
If you have not yet installed Dynamic C version 10.50 (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.
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 folder where Dynamic C was installed.

2.3.1 Troubleshooting

It may be possible that your PC or laptop is unable to deliver enough current through the USB connection if you are not using a separate power supply. The RCM5600W will not operate in this case, and the solution is to use a separate 5 V power supply as described in the Alternate Power Supply Connections section. Contact Technical Support (see Section 2.4.1) or visit our Web site if you would like to get the universal AC adapter from the Deluxe Development Kit.
If you receive the message
Could Not Open Serial Port, check that the COM port
assigned to the USB cable was identified and set up in Dynamic C as described above. This same error occurs when Windows has already allocated the COM port to another process.
If you receive the message No Rabbit Processor Detected, the USB cable may be connected to the wrong COM port, or the connection may be faulty. First, check both ends of the USB cable to ensure that it is firmly plugged into the PC and the USB connec­tor in the Interface Board. Ensure that the module is firmly and correctly installed in its connector on the Interface 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 recom p il e t h e BIOS. You should receive a BIOS
successfully compiled

message once this step is completed successfully.

2.4 Where Do I Go From Here?

3. RUNNING SAMPLE PROGRAMS

To develop and debug programs for the RCM5600W (and for all other Rabbit hardware), you must install and use Dynamic C. This chapter provides a tour of its m ajor feat ures w ith res pect to the RCM5600W.

3.1 Introduction

To help familiarize you with the RCM5600W modules, Dynamic C includes several sample programs. Loading, executing and studying these programs will give you a solid hands-on overview of the RCM5600W’s capabilities, as well as a quick start with Dynamic C as an application development tool.
NOTE: The sample programs assume t hat you hav e at least an elementary grasp of ANSI
C. If you do not, see the introduct ory page s of the Dynamic C User’s Manual for a sug- gested reading list.
In order to run the sample programs discussed in this chapter and elsewhere in this manual,
1. Your RCM5600W must be installed on the Interface Board as described in Chapter 2, “Getting Started.”
2. Dynamic C must be installed and running on your PC.
3. The USB cable must connect the Interface Board to your PC.
4. Power must be applied to the RCM5600W through the Interface Board.
Refer to Chapter 2, “Getting Started,” if you need further information on these steps. To run a sample program, open it with the
and run it by selecting Run in the Run menu (or press F9). The RCM5600W must be in Program Mode (see Figure 11) and must be connected to a PC using the USB cable.
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 RCM5600W. These programs will be found in the SAMPLES\RCM5600W folder. Sample programs in the SAMPLES folder one level up are generic samples that can be run on any Rabbit-based product.
Before you compile and run the fol­lowing sample programs, make sure that pins 1–2, 5–6, and 7–8 on header JP1 of the Interface Board are jumpered. The pins on header JP2 must also be jumpered. Each sample program has comments that describe the purpose and function of the program. Follow the instructions at the beginning of the sample program.
CAUTION: Do not jumper pins
1–3 on header JP1 on the Inter­face Board.

The Digital I/O accessory board may also be used to run the TOGGLESWITCH.C and the
SERIALTOSERIAL.C sample programs. This accessory board is included only with the
Deluxe Development Kit. To install the Digital I/O accessory board, insert the strip of header pins included with the
accessory board into the socket at J12 on the bottom side of the Digital I/O accessory board. Then line up the Digital I/O accessory board with the Interface Board standoffs/ connectors and install the Digital I/O accessory board pins into socket J2 on the Interface Board. Secure the Digital I/O accessory board with the long plastic standoffs/connectors from above as shown in Figure 6—note that one plastic standoff/connector needs to be inserted “upside down” to secure the Digital I/O accessory board to the antenna bracket.
