型號(hào)： XTR7020A8

類別： 集成電路

描述： The XTR-7020A-8 multichannel transceiver represent a simple and inexpensive additional solution to the problem of wireless data transmission. The integrated microprocessor is accepting data entering from a TTL logic RS-232 line, creating packets, avoiding user to write software routines for the transmission management. The XTR-7020A-8 features, using programmable internal registers, channel setting (7 channels in the 868MHz License Free band), choice of serial data rate (9600-19200-38400-57600-115200bps) chosen via module input pins and choice of emitted RF power from -8 to +10dBm. RS232 serial speeds may be differently settled in the two modules of the radio link. The store and forward technique used to send the data allows 240 bytes of maximum data packet length. A sophisticated transmission technique used on the digital data, validation of received data support distance in free air of 300 meters. . Micro controlled embedded 7 channels .
