TSK-RPM3-914-17RPM3-914-17-ANT UHF Radio Packet Modem

Radiometrix Ltd. UHF FM Radio Packet Modem page 1 The UHF Radio Packet Modem (RPM3) is a low cost intelligent radio packet modem that enables a two way radio network/link to be simply implemented between a number of digital devices. The RPM3 uses addressable data packets with error checking, packet acknowledgements and retransmissions to achieve a reliable transparent wireless data link. Built for ease of use and rapid installation, the serial interface ensures direct connection to microprocessors or to RS232 port via RS232 driver while remote configuration enables post installation setup of the modem.

UHF FM Radio Packet Modem page 2 INTRODUCTION The RPM3 is a self-contained Radio Packet Modem module that requires only a simple antenna, 5V supply and a serial I/O port on a host microcontroller or PC. The module provides all the RF circuits and processor intensive low level packet formatting and packet recovery functions required to inter-connect any number of devices with serial port in a radio network. A continuous stream of serial data downloaded by a Host microcontroller into the RPM3 serial receive buffer is transmitted by the RPM3’ S transceiver and will "appear" in the serial buffer of the addressed RPM3 within radio range. Figure 2: Point to point wireless link with RPM3 + Host microcontroller 1. FUNCTIONAL DESCRIPTION The RPM3 is a connection oriented modem module for sending and receiving serial data via an RF communications link. The RPM3 handles all necessary protocol related functions of validation and retries to ensure error free and uninterrupted data is sent over the communications link. All data transfers between a pair of RPM S are fully acknowledged, thus preventing the loss of data. Bit coding and checksums are used on the data packets to ensure the validity of the received data at the remote end. Figure 3: RPM3 block diagram Radiometrix Ltd. UHF FM Radio Packet Modem page 3 1.1 OPERATING STATES The R ADIO PACKET MODEM has three normal operating states: • S HUTDOWN • S TANDBY • C ONNECTED S HUTDOWN The S HUTDOWN state is entered by asserting the WAKE/DTR input pin high (Vcc). It effectively forces the RPM3 into a suspended state. Communications cannot be made with the RPM3 in this state. WAKE/DTR pin should be pulled Low by host or connected to 0V to Enable the RPM3. S TANDBY Immediately after power up and during normal operation, the RPM3 will automatically enter standby mode where it is waiting for a connection request from a remote RPM3 module. While in this mode a remote connection request can be received which will place the RPM3 into a connected state allowing it to then start receiving data from the remote unit. The connected host device can also send data to the RPM3 via the serial interface which will force the module to send a connection request to the remote RPM3 module, thus effectively setting up a logical connection between two units and allowing data to be transferred. C ONNECTED On receipt of a connection request from a remote unit, the RPM3 immediately enters a connected state. This effectively allows the RPM3 modems to start sending and receiving data. In-coming data is sent to the host via the serial port in the same form as it was given to the remote RPM3 module.

UHF FM Radio Packet Modem page 4 2 The Host Interface 2.1 SIGNALS The connection to the RPM3 is a full duplex serial interface supporting baud rates from 600bps to 115200bps. Additional control signals are provided to assist in flow control, configuration and power saving in the RPM3.

Monday, 28 November 2005 Equipment Authorization Branch Federal Communications Commission 445 12th Street SW Washington, DC 20554 USA To whom it may concern, PART 15 Unlicensed Modular Transceiver Approval for RPM3-914-17-ANT We would like to apply for Modular Transceiver Approval for RPM3-914-17-ANT which has been verified to comply with relevant FCC rules by RFI Global Services Ltd (RFI) which is an accredited Telecommunication Certification Body (TCB) RPM3-914-17-ANT is a complete RF transceiver module. It has its own crystal controlled Phase Locked Loop (PLL) synthesiser with Voltage Controlled Oscillator (VCO) and antenna coupled to the module using unique Reverse Polarity SMA connector. It just requires power supply and serial data. RPM3 uses BiM3A RF transceiver which has its own RF shielding can. Module has restricted data input baud rates from 600bps to 115200bps with internal microcontroller modulating the carrier with a maximum of 64kbps bit rate. BiM3A transceiver in RPM3 has its own internal voltage regulator to provide constant 2.8V supply to internal RF circuit. RPM3-914-17-ANT is a RPM3-914-17-RPS with Reverse Polarity SMA (RPSMA) connector coupled to a ¼ wavelength monopole antenna with another unique RPSMA connector. RPM3 complied with the AC line conducted requirements of Part 15.207 in stand-alone configuration. Required FCC Labelling is described clearly on the data sheet for the RPM3. RPM3-914-17-ANT using BiM3A-914-64 transceiver complies with FCC Part 15.249 with the Electric Field Strength of 43.7mV/m (50mV/m is the limit). As the Electric Field Strength at 3m for the module is lower than 50mV/m, RF exposure requirement may not apply. However, end-user must take necessary precaution so that the final product complies with RF Exposure requirement. Both Transmitter and Receiver portion are verified to comply with FCC Part 15 requirement. Yours truly, Sabananthan Paramananthan Technical Manager
