QR5ROTR00471ROTRONICS 915MHz RADIO MODULE

Rotronics Systems Limited MiWi module – FRZ200 – 1000 Module user guide – Rotronics Systems internal use only. 1.1General description This module is a radio data transmitter / receiver using FSK modulation operating on 915mHz for short range telemetry. It has been developed for Next Control Systems in the UK as a component module part of a remote temperature measurement system. 1.2Warning notice The module RF stage is not to be modified in any way without repeating RF compliance testing. The RF and micro-controller stages must not be fed from a DC supply greater than 3.6v. No other antenna apart from the 1/4wave screw on antenna may be used with this module. 1.3Technical specifications Operating frequency 915.000mHz. RF power output 90.9dBuV/m (-15dB). Modulation FSK 200kHz deviation. DC power supply 3.6v DC. Inputs analogue (0-2.500v) and digital (I2C). 1.4Hardware description The module circuit board measures 80mm long x 42mm wide. Height with battery fitted is 20mm. Primary electrical interconnections are via a 9 way FFC connector. There are links for setting options, see 1 . 5 below, and connections for in-circuit programming of the processor and reading the unique MAC address back for identifying individual modules. 1.5Circuit description Read in conjunction with “Transmitter120.pdf” circuit diagram. The RF chip (IC1) is an integrated, single chip ISM band sub-GHz transceiver. It has a inbuilt frequency synthesiser clocked by a external 10mHz crystal and generates 915mHz radio frequency. The receiver is zero-IF architecture and has the following components: LNA, down conversion mixer, channel filter, baseband limiting amplifier and received signal strength indication (RSSI). IC 1 has an internal transmit / receive switch with a external impedance matching network coupling to the screw-on 1/4wave antenna. The quality of received data is checked and validated with RSSI and DQI (Data Quality Indicator) blocks built in internally. The RF transceiver chip is controlled through a 4-wire SPI bus from a Microchip controller on the module. The SPI bus is connected to two local memory chips, the MAC address chip (IC3) which is pre-loaded with a unique address for each module, and a EEPROM memory (IC2) to store data blocks if the transceiver is unable to communicate with it's host for a period. The Microchip controller (IC4) has two clocks, a standard clock crystal (32.768kHz) for the period timing and an internal 12mHz oscillator for the processor clock. The controller has three 10bit ADC ports, a USB port and a I2C serial data port. A board mounted 3v6 Li-SOCI cell is the normal source of power when the module is used with an analogue signal conditioning option board to measure temperature with a probe. External 5v DC power connection when the unit is used in the controller is regulated on the module to 3v3 DC. The module has three possible modes of operation, as a remote radio data transceiver, a repeater to pass the data through, and a controller which communicates with the remote data transceivers. These options are set using solder bridges on Lk1 and Lk2 Remote radio data transceiver – no links Repeater radio transceiver – link Lk2 Controller for network – link Lk1 & Lk2 1.5Board interconnections Read in conjunction with “Transmitter120.pdf” circuit diagram Cn 1 – M4 threaded fixer for ¼ wave antenna. Cn 2 – Programming header for manufacturing use only. Cn 3 – Data and power connector for MAC reading and control. Cn 4 - Panel reset switch – membrane connector. Cn 5 – Analogue and I2C connections to signal conditioning option boards. Cn 6 – Connector for temperature and humidity module (Sensiron part). 1.6System description The controller, model number GENII/WARP/200, monitors and stores readings from the remote transmitters, displaying parameters on a 4.3” LCD display, with toggle buttons on a panel membrane to view readings from the different remote transmitters. The controller comprises a MiWi module ( FRZ200 – 1000 ), an embedded computer module (Re2) and a mother board that holds these two units, provides DC voltage power conversion, and interfaces to the LCD screen mounted on it's rear. The controller is powered by a plug top DC power supply, 15v 5w. - The remote transmitter, model number GENII/FRZ/200A and B, measures up to two temperatures using platinum temperature probes. The remote transmitter comprises a MiWi module ( FRZ200 – 1000 ) and an analogue signal conditioning option module that can be set to different ranges, A and B. The remote transmitter is powered by a 3v6 LiSOCI cell. Energy saving techniques are used to achieve up to 4 year battery life. - The repeater, model number GENII/SRPT/200, receives remote transmitter's in it's vicinity and automatically associates itself with either a controller, or another repeater to pas the data back to the controller. The repeater comprises a MiWi Module (FRZ200 – 1000 ) and a battery backup board to provide a 21 hour backup in the event of mains loss. The controller is powered by a plug top DC power supply, 12v 1w. - 1.7Module operation A remote radio data transceiver, when first powered up or, whenever the front membrane button is pressed and released, will transmit association data packets based on the unique MAC address factory set in IC3. The controller will receive these data packets, and pass them to an embedded computer module which checks that the MAC address of the transmitter module exists within its database. If the MAC address is not in the embedded computer module table then it will not respond to the remote transmitter. If the MAC address is in the computer table then it will transmit an acknowledgement to the remote transmitter and an association communications link is created between the specific remote transmitter and the controller. Up to 120 remote transmitters can be used. Thereafter, at 60 second intervals, the remote transmitter will wake up, transmit its sensor values to the controller, and wait for an ackn…
