RW3RFS1RFS USB Transceiver

Annex No.5 User Manual Functional Description Radio System for Studio Flash Equipment 916.5MHz: RFS USB Transceiver L7254.01 914.0MHz: RFS USB Transceiver L7254.03 Bron Elektronik AG, 4123 Allschwil, Switzerland The application concerns the data transmission from an operator console (MAC/PC) to the flash units of a Photo Studio, in both directions, as well as the transmission of a flash trigger signal from the camera to all of the flash units. The RFS USB transceiver is plugged in the PC/MAC. The power supply is supplied from USB Hup. RFS USB Transceiver specifications ( typical ): • Output power: 12dBm • Frequency: 914.0-916.5MHz • Modulation: ASK • Data rate / Data format: 38.4 kBaud Æ 76.8kBit in Manchester • Transmission time flash triggering: 0.625ms – 0.833ms • Transmission time data-block: 1.9ms – 10.4ms • Size: 80mm x 55mm x 30mm • Operating voltage / current: RF 3V / 2mA • Operating voltage / current: USB: 5V / 25mA • Operating current USB Suspend: 100μA • RF input impedance 50 ohms • Antenna: Helical SMA • USB specification: USB 2.0 • LED: Communication indicator • Switches: „test“ transmit flash block „+“ and „-„ transmit data block • Sync connector: transmit flash block Transmission format Data format: MSB first Flash-block: • Preamble 11100110 01100110 optimisation of DC-balance • Start symbol „Flash“: 01110001 11010110 Manchester modified • ID (Studio no.) 01010101 01010110 Æ ID=1 ( Manchester ) Data-block: • Preamble: 11100110 01100110 optimisation of DC-balance • Start symbol „Data“: 01110001 11011001 Manchester modified • Block number: ... each new block receives a new block number, but not a repetition. • Byte count: ... • Start info: 01011010 01011001 • Studio ID: 01010101 01010110 Æ ID=1 ( Manchester ) • Unit ID: ... • n data ... ... ... ... max. 50 Byte • Check sum: ... • End Symbol „Data“: 01110110 00100110 Manchester modified A dual directional data transmission only takes place when the setting on the flash units or the operator console (MAC/PC) is adjusted. This reduces the probability of a collision with a flash- block. A correctly transmitted data-block is confirmed with an ACK. An unconfirmed data-block is repeated. A flash-block is not repeated. 106-108 Anglesey Business Park, Littleworth Road, Hednesford, Staffs. WS12 5NR.

(9/2001) MOBILE MARKMOBILE MARK COMMUNICATIONS ANTENNAS R 1/4 wave Device Antennas Quarterwave antennas provide performance for products with the minimum of size. Full length quarterwave design provide the maximum efficiency, while loaded helical stub antennas provide minimum size. The full length models use a flexible whip, whereas the helical antenna use a hard radome. Overall performance of quarterwave antennas does depend on the ground plane provided by the radio system or the mounting configuration. Quarterwave antennas are broadband compared to other designs and can effectively be used in most apllications. For OEM applications, performance can often be maximized with a one time factory adjustment. Connector styles available are TNC, SMA, MMCX or a thread ferrule assembly. The thread ferrule provides the most economical solution, but does require a special mechanical configuration for mounting and feeding the RF signal. Special connectors are also available, please consult factory. Models with "-925 designators also overlap the ISM 902- 928 band and are now in lieu of the "-915" models.
