RADIO MODEMS 868MHz Multichannel Radio Modem based on RadioControlli RCS1KSMT-868 device The RCQ2-868-PCB is a high performance wireless modem providing a reliable low cost serial data communications link that can be used for many data communications applications at an exceptionally competitive price. The modem operates in the ISM 868 MHz band. The RF modem is very simple to use and provides a wireless RS232 link with a RF data rate of up to 100 kbps. The transceivers have the functions of a complete radio modem and simply require CMOS/TTL data at the transmit input and the corresponding transceiver(s) output the same data. Preamble and CRC are automatically generated and added to the RF transmission. step. Possible applications include one-to-one and multi-node wireless links in applications including security EPOS, wireless sensor network, industrial process monitoring and computer networking. Because of their small size and low power requirements, (the consumption in power down mode is < 2uA) this module is a ideal for use in portable, battery- powered applications such as hand-held terminals. - Wireless security systems - Home and building automation - Automatic Measure Reading - Industrial Control and Monitoring - Wireless Sensor Network - EPOS Terminal Operating Mode : - Radio Modems Application Inside - Serial Data Interface with Handshake - Host Data Rate up to 115200 Baud - Very Stable Operating Frequency The information contained in this document may be changed without notice.

RADIO MODEMS The RCQ2-868-PCB Radio Modem has applications in many areas where reliable half duplex communications are required over ranges up to 200 meters (with the maximum RF Power is possible to The crystal controlled narrow band design, in the embedded RCQ2-868-PCB device, gives reliable performance within the 868 MHz band. The addressing protocol employed enables many different configurations such including: one-to-one operation: for point to point data communication; broadcast operation: where a single master address many RCQ2-868-PCB modules concurrently (using many RCQ2-868-PCB...

RADIO MODEMS The RF Channel is calculated in this mode: 868 MHz working frequency : Configuration value (decimal) = [(desired RF frequency / 2) - 422.4MHz] * 10 The Configuration pin (Pin 7) must be low (ground) to set up the RCQ2-868-PCB module into configuration mode. If the Configuration pin is still low at the end of the configuration then the module will send the current configuration back to the host. To retrieve the current configuration without changing any options the host can send a single byte to the module and wait for the response. The RCQ2-868-PCB module will accept a short...
