Radiocrafts公司的RC1180-KNX是表面安裝的高性能發(fā)送模塊,它的尺寸僅為12.7 x 25.4 x 3.3 mm,能很容易集成在傳感器或激勵器中,采用UART接口作為串行通信和配置,天線直接連接到RF引腳,適合歐洲標準(CENELEC EN 50090和CEN EN 13321-1),國際標準(ISO/IEC 14543-3),中國標準(GB/Z 20965)以及美國標準(ANSI/ASHRAE 135).工作頻率868.0 – 870.0 MHz,工作電壓2.0 – 3.9 V,并具有超低功耗,主要應(yīng)用在家庭和建筑物控制,HVAC,AMR和自動讀表以及網(wǎng)關(guān)等.本文介紹了RC1180-KNX主要特性, 典型連接圖, 應(yīng)用示意圖以及三種RCxxxxDK-USB演示板方框圖,電路圖,材料清單以及PCB元件布局圖. The RC1180-KNX® RF Transceiver Module is a compact surface-mounted high performance module with embedded KNX-RF Multi protocol as defined by the KNX Association (www.knx.org). The module has a UART interface for serial communication and configuration. The module is pre-certified for operation under the European radio regulations for license-free use and measures only 12.7 x 25.4 x 3.3 mm with shielding. When used with quarter-wave antennas a line-of-sight range of 600-800 meter can be achieved. The RC1180-KNX meets the KNX specification and supports S, A and E modes, and operates in the 868 MHz frequency band. The physical layer complies with the relevant parts of the EN 50090 (ISO/IEC 14543-3). RC1180-KNX主要特性: Embedded KNX-RF protocol (KNX-RF v1.1, KNX Ready and KNX-RF Multi) Frequency agility, by using up to 5 channels Fast link acknowledgement of up to 64 receivers Automatic retransmissions Repeaters, extending range of KNX-RF Multi messages by 2 hops and KNX-RF Ready messages by 6 hops Binding of up to 64 other KNX-RF devices Listen Before Talk (LBT) to reduce collisions Automatic battery supervision Received Signal Strength Information (RSSI) Pin compatible with the Wireless M-Bus module RC1180-MBUS 12.7 x 25.4 x 3.3 mm compact module for SMD mounting Completely Shielded Wide supply voltage range, 2.0 – 3.9 V Ultra low power modes for extended battery lifetime Conforms with EU R&TTE directive (EN 300 220, EN 301 489, EN 60950) Confirms with EN 50090 (ISO/IEC 14543-3) Designed for EX compliance RC1180-KNX應(yīng)用: Home and building control HVAC AMR, Automatic Meter Reading Gateways KNX RF/KNX-IP/KNX Twisted Pair

圖2.RC1180-KNX典型應(yīng)用示意圖 RCxxxxDK-USB演示板 The Demonstration Kit (DK) is designed to make it easy for the user to evaluate the onboard module, develop an application and build prototypes very quickly. The kit includes two Demo Boards (DB). The demo board contains the selected module with its dedicated article number and embedded protocol and associated support circuits. The board can easily be operated using a PC terminal emulator or the RCTools PC suite from Radiocrafts.
圖3.RCxxxxDK-USB演示板外形圖 The Demo Board contains USB connector, USB to serial converter, buttons, LEDs, voltage regulator, configuration jumpers and connectors to make it easy to interface the onboard module with various test equipment or the host used in an application. Not all components are needed in an actual application. Please see the datasheet for each specific module for a typical application circuit. The Demonstration Board comes in different versions, equipped with the different variants of Radiocrafts modules. Among the frequencies supported are 433 MHz, 868 MHz, 915 MHz and 2.45 GHz. For each frequency there exist narrowband versions and wideband versions. This covers the most used frequency bands, the 433 MHz band in Europe and the US, the 868 MHz band in Europe, the 902-928 MHz band in the US and the 2 450 MHz band worldwide. The actual module mounted can be seen on the marking on the module itself.
