Wireless modem RCQ2-868-S

RS485RFISM band

RCQ2-868-S 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. The RCQ2-868-S can use any channel in 100 (200) KHz 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 < 2µA) this module is ideal for use in portable, battery-powered applications such as hand-held terminals. - Technical Characteristics - Supply Voltage: Min 2.20, Typ 3.0, Max 3.6 Volt - Current Consumption (RX mode): Typ 20 mA - Current Consumption (TX Mode +20dBm): Typ 85 mA - Current Consumption (TX Mode +0dBm): Typ 10 mA - Current Consumption Sleep Mode: Max 2 µA - Power up to stable receiver data out: Typ 30 msec - Power up to full RF Power out: Typ 30 msec - Standby to Receive mode: Typ 1 msec - Standby to Transmit mode: Typ 1 msec - Frequency Range: Min 868.00, Max 870.00 MHz - RF Output Power: Min 1, Max +20 dBm - RF Sensitivity (1.2Kbit/sec Data rate): Typ -121 dBm - Frequency Deviation: Typ ±50 KHz - GFSK Manchester encoded data rate: Typ 100 Kbps - Operating Range Temperature: Min -10, Max +55 °C - Pin Configuration - 1: VCC - Power Supply - 2,3,4,6: GND - Ground - 5: ANT - Antenna - 7,8: ---- - Not Used - 9: PD - Power Down Mode - Input - 10: TX - UART RX - Input - 11: RX - UART TX - Output - 12: DR1 - Data rate Selection - 13: DR2 - Data rate Selection - 14: CONFIG - Configuration Mode - 15: RTS - Request to Send - Input - 16: CTS - Clear to Send - Output - Model: RCQ2-868-S - ISM 868 MHz band operation - Wireless RS232 link - RF data rate up to 100 kbps - Low power consumption (<2µA in power down mode) - Small size, suitable for portable, battery-powered applications
