2. Application Schemes
The Development Kits can be used in 2 different application schemes.
Evaluation Scheme:
Configuration Scheme:
Main product features can be configured and evaluated/demonstrated in this scheme.
All product features of can be configured in this scheme.
2.1 Evaluation Scheme
The necessary components of the evaluation scheme are:
Two RF-EBs
CMT211xA-EM
CMT221xA-EM
Main product features can be evaluated and demonstrated in this scheme. Follow the step-by-step instructions to start working in the Evaluation Scheme.
1.
Turn off the RF-EB power switch (SW1, see Figure 6 in Page 10). It is always good practice to plug in or out the evaluation modules after the RF-EB is powered off.
2.
Switch the Power Mode Jumper (J7, see Figure 6 in Page 10) to the USB or BAT side to select the available power supply source.
3.
Plug the evaluation modules into both RF-EBs respectively. Please note that there are 2 sets of evaluation modules and antennas, the user should pair them properly according to their frequency labeled on them.
4.
Turn on the power switch (SW1) of the RF-EB. The LED indicator for the power supply indication will be light up to show to
“ON” status of the RF-EB.
5.
Start to configure the evaluation modules according to the instructions displayed on the LCD and then evaluate the main features/performance.
2.2 Configuration Scheme
The necessary components of the configuration scheme are:
RFPDK
USB Programmer
CMT211xA-EM or CMT221xA-EM
This scheme allows the user to freely customize all product features and program them into the chips. Once the programming is done successfully, the evaluation module is ready to be integrated into the user’s own application systems. Moreover, the users can program chip configurations to their self-designed CMT211xA/221xA modules as long as the programming interface is reserved.

Figure 3. Configuration Setups
Follow the step-by-step instructions to start working in the Configuration Scheme.
1.
Setup the configuration scheme as Figure 3.
2.
Install the USB Programmer driver. The driver will be installed automatically on the computer. It should be noticed that if the RFPDK is already installed on the computer, make sure that the RFPDK is not running when the user is installing the
USB Programmer driver.
3.
Install the RFPDK to the computer. Refer to Section 7.1 for the detail procedure for the installation.
4.
Start Configuring CMT211xA/221xA on the RFPDK and the USB Programmer. Once the configuration is done, the user can use the evaluation modules in the actual RF system.
Please refer to the “Chapter 7. RFPDK” for the RFPDK usage guidelines and refer to the following documents for more details.

3. CMT211xA-EM
The CMT211xA-EM is a Tx evaluation module with CMT211xA, the necessary external components and the matching network.
The EM-Connector on the back side of the module allows the connection to the RF-EB or USB Programmer. The definitions of
the EM-Connector pins are listed in Table 1.

The module can be used in the following schemes (see Chapter 2 for details)
1.
Work with RF-EB in Evaluation Scheme
2.
Work with USB Programmer and RFPDK in Configuration Scheme
The evaluation module contained in this Development Kits is designed with the matching network at 433.92 MHz. For application with different frequencies, the matching network might need to be changed.
See “Chapter 10 Appendix: CMT211xA-EM and CMT221xA-EM Schematics” for the CMT211xA-EM Schematic.
