... Hartcran House, 231 Kenton Lane, Harrow, HA3 8RP, England 24 April 2007 UHF Radio Packet Modem The UHF Radio Packet Modem (RPM2A 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 RPM2A uses addressable data packets with error checking, packet acknowledgements and retransmissions to achieve a reliable transparent wireless data link ...

... D UNCTIONAL ESCRIPTION The RPM2A is a connection oriented modem module for sending and receiving serial data via an RF communications link. The RPM2A 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 are fully acknowledged, thus preventing the loss of data ...

... The connected host device can also send data to the RPM2A via the serial interface which will force the module to send a connection request to the remote RPM2A module, thus effectively setting up a logical connection between two units and allowing data to be transferred ...

... The Host Interface 2.1 S IGNALS The connection to the RPM2A 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 RPM2A. RF GND GND 3 RX SELECT 4 TX SELECT 5 GND ...

... The Setup pin may either be driven by the host (recommended) to enable host controlled configuration of the RPM2A or pulled 2 ORCING EFAULT ERIAL Asserting this pin low forces the RPM2A to start-up with a default baud rate of 9600bps, 8 data bits, one stop and no parity. D EFAULT During a R the H ESET OST to 9600bps ...

... LO leakage (conducted) Transmitter Output Power (typical) Spurious Emissions Note: 1. RPM2A uses BiM2A (64kbps UHF Wide Band FM) transceiver for its RF interface. Please refer to BiM2A data sheet for further details on the RF specification. 2. BiM2A consumes 14mA on transmit and 11mA on receive Radiometrix Ltd. TECHNICAL SPECIFICATION ...

... ADIO ACKET ODEM ONFIGURATION 3 NTERING HE ONFIGURATOR The RPM2A is configured by entering the built-in software configurator. Current argument can be displayed by entering parameter / command without argument 3 SER ONFIGURABLE ARAMETERS C Display a list of the current RPM2A configuration. ONFIG This will also set Valid range None D Set all RPM2A configuration settings to their factory default values. ...

... F Sets the serial flow control between the host and RPM2A. LOW Using no flow control enables the RPM2A to be used with a 3 wire serial link (TXD, RXD, GND). Care must be taken in order to prevent overflowing the 96 byte serial receive buffer in the RPM2A. Using hardware flow control enables the RPM2A to control the flow of serial data being received ...

... Figure 6: Serial Port settings to use RPM2A Configurator Hardware flow control should be disabled. Default baud rate of the RPM2A is 9600bps. However if the default baud rate of the RPM2A is changed then the baud rate of the HyperTerminal should be matched or DEFAULT pin should be pulled Low to force the RPM2A baud rate to 9600bps. ...

... The RPM2A supports three rates, max (17kbps), slots (3.6kbps) and slotsw (1.8bps), of over-air throughput When set to maximum and streaming data at the RPM2A, the data is sent as quick as AX possible. For host baud rates above 9600bps, data is transmitted continuously with minimal delay between sequential packets. When this occurs, there is effectively no airtime for another pair, operating in close proximity, to transmit without causing collisions ...

... This setting effectively widens the LOTSW throughput to approximately 1.8kbps (with/without ACK). It allows more RPM2A pairs to share the same frequency. Host should obey CTS flow control signal from RPM2A when using SLOTS or SLOTSW mode. Figure 11: RPM2A operating in slotsw throughput mode Overall throughput of the RPM2A is fixed according to thruput mode selected. Effective throughput will vary according to the file transfer protocol used ...

... A DDR provided the parameters are correct, the configurator is exited immediately. A period (‘.’) is sent to the connected host device to indicate that the change has been registered and the RPM2A is now ready for communications to the new unit address very similar to the Unit command, except that A DDR value ...
