Pinout Block diagram Page 4 of 8 Author: Radio Group Date: February 11th, 2014 Subject: Integration Guide – Mizar Radio Module 915 MHz Operational description The equipment is a radio module to be integrated inside cordless devices. It is based upon an FSK ( Frequency Shift Keying Modulation ) Half-Duplex transceiver working in the ISM band from 902 to 928 MHz. The radio module has a UART interface to exchange data and commands. Working modes Radio module can operate in the follow working modes : Low Speed, Low Power, fixed channel (among 25 channels) o FSK, Bitrate 36864 bps, RZ Manchester encoded, Frequency deviation +/- 75KHz Low Speed, Frequency Hopping Mode over 25 channels o FSK, Bitrate 36864 bps, RZ Manchester encoded, Frequency deviation +/- 75KHz High Speed, Digital Transmission Mode, fixed channel (among 12 channels) o FSK, Bitrate 500,000 bps, NRZ, Frequency deviation +/- 220KHz High Speed, Digital Transmission + frequency agility Mode over 12 channels o FSK, Bitrate 500,000 bps, NRZ, Frequency deviation +/- 220KHz Default mode after power-up is Low Speed Low Power mode. Radio module can receive commands to allow to change its working mode. Functional states Radio module can be set in one of the following states during operation: Idle State Radio module stays in low power receiving mode with a limited capability to receive data. RF transmission is not allowed while radio is set in Idle state. Receive State It is the normal default state. In this state the radio receives the RF packets, decodes the packets and sends them to the Host device. In this mode the transceiver checks continuously the RF signal and demodulates it. The demodulated and filtered signal is sent to the microcontroller inside the radio module which decodes it and sends decoded data to the Host by means of the UART interface. Only valid demodulated data packets are sent to the Host. Transmission State This state is enabled from the host when it needs to transmit data. The transmission state is enabled sending a data packet to the radio module over the UART interface. The microcontroller in the radio module checks for the integrity of the data packet and enables the transceiver to modulate and transmit to the RF interface, preceded by a short preamble burst. Radio module exits automatically from this state when the complete packet has been transmitted, and returns to the receive state. Page 5 of 8 Author: Radio Group Date: February 11th, 2014 Subject: Integration Guide – Mizar Radio Module 915 MHz Radio module operates in CSMA-CA (carrier sense multiple access – collision avoidance) : transmission is enabled when the RF channel is not busy by the use of a “carrier detect” function. Radio module accesses the channel in a fair way using a backoff algorithm. Interface description (pinout reference) UART 2-pin interface, used to exchange data from the Host: DATA_OUT (output pin) : transmits data to Host. DATA_IN (input pin) : receives data from Host. CD# – (output pin) Carrier Detect : When radio is in receive mode, this pin signals the presence of RF carrier. IDLE - (input pin) : A high level on this pin forces the radio module in Idle State. RESET (input pin) : A low level on this pin resets the radio module. VCC and GND : Radio module power supply. RF Port : Radio Frequency Connector for the antenna.
