4 2. CEL HARDWARE: ZFSM / ZFSM-201-1C (Module) 2.1 Low RF Power Out on Transmission As outlined in the ZFSM datasheet, the voltage regulator which supplies the onmodule power amplifier has a 105 µs turn-on time. In order to transmit at maximum power the voltage regulator must be fully turned on. The voltage regulator s active-high enable signal is directly connected to the MC1322x s GPIO42. Every time the voltage regulator is disabled (turned-off) and then re-enabled, the 105 µs turn-on time requirement needs to be met in order to transmit at full power. The pre-programmed module software places GPIO42 under software control such that the module begins transmitting only after the voltage regulator has been fully turned-on. 2.2 RF Output Power Settings In order to comply with FCC requirements, only a subset of the MC1322x available power settings is allowed. For users using the BeeKit as a starting point for code development, the allowed power settings are (0x00-0x07, 0x0D and 0x11) for channels and (0x00-0x07) for channel 26. These settings provide output powers ranging from approximately 0-10 dbm and 20 dbm. Users can either choose the Power Lock selection in BeeKit (enabled by default when using the provided BeeKit plugin) or must provide these power step restrictions in their own software. The user assumes full liability if FCC requirements are not satisfied when using any other power settings. In addition to restricted power settings, the user must also restrict the duty cycle of the transmitter transmission. 2.3 RF Duty Cycle In order to comply with FCC requirements, the software must ensure the module is transmitting for a maximum 17 ms in any 100 ms time frame. Failure to do so, results in the user assuming full responsibility for complying with FCC regulations. Typically, this should only affect SMAC-based implementations as the MAC implementation utilizes a scheduler which handles the duty-cycle requirement. For a typical application at the MAC layer, a packet message of 133 bytes will result in a transmission time of 4.26 ms. Assuming no acknowledgements are received, the module can transmit again up to three more packets resulting in a total transmission time of 17 ms with in the 100 ms time frame - satisfying the duty cycle requirement. The pre-programmed module software is MAC-based and thus is not affected by the duty cycle requirement. 2.4 Freescale MC13224V Errata The CEL FreeStar Pro module is also subject to the errata listed by Freescale Semiconductor for the MC13224V device.

5 3. CEL HARDWARE: ZFSM-201-EVB-1 (Evaluation Board) 3.1 UART Communication at Operating Voltages below 3.3 Volts The FTDI USB-to-RS232 bridge chip has an operating supply voltage range of 3.3 to 5.25 Volts. On the ZFSM-201-EVB-1, the FTDI VCC supply is fed by the same supply voltage as the FreeStar Pro module. As such communications with the FTDI chip will fail when operating the module at a voltage below the FTDI minimum operating voltage of 3.3 Volts. 4.
