Introduction

CMT2110A/2210A One-Way RF Link Development Kits (Development Kits) are a set of the hardware and

software tools designed to help the users to easily evaluate the performance and demonstrate the features of

products CMT2110A and CMT2210A. These two devices are part of the CMOSTEK Microelectronics Co., Ltd.

(CMOSTEK) NextGenRFTM family, which include a complete line of transmitters, receivers and transceivers. The

CMT2110A is an ultra low-cost, highly flexible, high performance, single-chip OOK transmitter for various 240 to

480 MHz wireless applications. The CMT2210A is an ultra low-cost, highly flexible, high performance, single-chip

OOK receiver for various 300 to 480 MHz wireless applications. These two devices are optimized for the low

system cost, low power consumption, battery-powered one-way RF link application with their highly integrated

and low power design.

The Development Kits contain the components of two evaluation boards named RF-EB, a Tx evaluation module

named CMT2110A-EM, an Rx evaluation module named CMT2210A-EM, a USB Programmer and a PC

application named RFPDK (RF Products Development Kit). The package of the Development Kits is shown in

Figure 1.

RF-EB

General purpose

evaluation board for the

CMOSTEK RF products. It can be used to evaluate

and demonstrate the main features of CMT2110A,

CMT2201A and other RF products.

CMT2110A-EM

The CMT2110A-EM is the Tx evaluation module.

The user can use it to evaluate the CMT2110A

performance and features.

CMT2210A-EM

The CMT2210A-EM is the Rx evaluation module.

The user can use it to evaluate the CMT2210A

performance and features.

RFPDK

CMOSTEK provides the PC application that allows

the users to configure all the product features to

CMOSTEK NextGenRFTM products in the most

intuitional way. The installation pack can be found on

the CDROM of the CMT2110A/2210A One-Way RF

Link Development Kits.

USB Programmer

It transmits data between the EM and the PC via two

interfaces: USB to PC and serial port to EM. The

protocols of the serial port differ for different parts

(chips). The USB programmer automatically

identifies the part on the EM once it is connected,

and then uses the desired protocol to communicate

to the part.

2. Application Schemes

The Development Kits can be used in 2 different application schemes.

Evaluation Scheme: Main product features can be configured and evaluated/demonstrated in this

scheme.

Configuration 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

CMT2110A-EM

CMT2210A-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

CMT2110A-EM or CMT2210-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 CMT2110A/2210A 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 CMT2110A/2210A 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 documents “AN102

CMT2110A Configuration Guideline”, “AN108 CMT2210A Configuration Guideline” for more details.

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: CMT2110A-EM and CMT2210A-EM Schematics” for the CMT2110A-EM Schematic.

5. RF-EB

The RF-EB is an evaluation board for demonstrating the main features of CMOSTEK NextGenRFTM products and

allowing the user to develop their own applications. The module can be used with the evaluation modules in

Evaluation Scheme (see Chapter 2 for details).

The main components are shown in Figure 6 below:

Figure 6. Top View of RF-EB

5.1 Main Components

1. EM-Connector –The EM-Connector is 10-pin, 2.54 mm female connector which connects the RF-EB to the

evaluation modules.

2. LED – There are 3 LEDs available to indicate the working status of the RF-EB.

LED1 indicates that the RF-EB received 1 frame successfully when working with CMOSTEK Rx

products.

LED2 indicates that the RF-EB transmitted 1 frame out successfully when working with CMOSTEK Tx

products.

LED3 is reserved for future use.
