  • Page 6: Application Schemes

    2. Application Schemes In order to help to user to start using the Development Kits easily, CMOSTEK has defined a few configurations with different application schemes on the RFPDK. The user only needs to follow the guidelines in the subsections of this chapter, program the configuration to the corresponding evaluation modules and start the evaluation.
  • Page 7: Led On/Off

    In the LED On/Off scheme, the user can experience to push buttons on the transmitter module to turn on and off the LEDs on the receiver module. Push buttons on the CMT2150A-EM and the 4 LEDs on CMT2250A-EM are shown and described as below.
  • Page 8: Pulse

    = Pin11 (K1) Notes: Please refer to the “AN112 CMT2150A Configuration Guideline” for the introduction of Toggle mode of the push button setting and the 1920 encoding format. The study function is enabled in this scheme, while the Sync ID on both of the Tx and Rx side are set to the same by default.
  • Page 9 USB cable, then start the RFPDK on the PC. Connect the CMT2150A-EM to the USB Programmer with EM-Connector, select CMT2150A on the RFPDK, stay in Basic Mode, select the Pulse configuration on the configuration list, as shown in figure below, and burn the configuration to the CMT2150A-EM.
  • Page 10: Periodic Tx

    2.3 Periodic Tx In the Periodic Tx scheme, the CMT2150A-EM will send out packets to the CMT2250A-EM automatically in every 3 seconds. The LED1-3 on the CMT2250A-EM will be turned on for 500 ms on each transmission. The push buttons are shown and described in the figure/table below: Rev 1.0 | Page 10 / 34...
  • Page 11 USB cable, then start the RFPDK on the PC. Connect the CMT2150A-EM to the USB Programmer with EM-Connector, select CMT2150A on the RFPDK, select the Advanced Mode, select the Periodic configuration on the configuration list, as shown in figure below, and burn the configuration to the CMT2150A-EM.
