RADIO MODEM Wireless Modules 869MHz Multichannel Radio Modem 500mW based on RadioControlli RCS1KPA-868 device The RCQ2-869-HP 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 Radiocontrolli s.r.l refuses any responsibility for irregular uses of the devices and for any possible lack or inaccuracy of the data and reserves the right to change in whole or in part these information without notice.

RADIO MODEM Wireless Modules The Data Rate pins (2,3) are read when the PD switch goes high (pin 13 = Vcc). The RCQ2-869-HP must be put into standby mode by taking the PD pin low (pin 13 = GND) to change the Baud Rate selection. The size of RF data packets are set in configuration mode. If fewer bytes are received by the RCQ2-869-HP module than the preset size, then after 10ms from the last byte received from the host, the RF packet will be processed (expanded to meet the preset packet size) and transmitted. The RF data packet size must be set the same for transmitter and receiver,...

RADIO MODEM Wireless Modules RF Channel frequency for default is fixed at 869.6MHz (parameter=7C) as recommended from the regulation CEPT/ERC Rec. 70-03 is possible to move this frequency only to 869.4MHz (paramer =7B). it is recommended not to use the device at different frequencies from the band 869.4 - 869.65MHz. The RF Channel is calculated in this mode: 868 MHz working frequency : Configuration value (decimal) = [(desired RF frequency / 2) - 422.4MHz] * 10 Radiocontrolli s.r.l refuses any responsibility for irregular uses of the devices and for any possible lack or inaccuracy of the...
