Overview: HY-RS485 series is a low cost, high performance transparent FSK transceiver with operating at 433 MHz. It features small size, high output power, high sensitivity,long transmission distance and high communication data rate with auto set up for communication change and data receiving and transmission control. There is RS485 interface, it is easy to realize the wireless data transmission with only providing the RS485 data. It is flexible for the users to set the RS485(UART) baud rate, frequency, output power, data rate, frequency deviation, receiving bandwidth etc parameters. It is your ideal choice for designing wireless data transmission products which can be widely used on wireless data transmission field. Features Baud Rate : 1200-115200bps(Default : 9600); Work voltage: 5V ( Range: 4.5~8V) ; FSK modulation, 2-way half -duplex communication, strong anti-interfere 433/470/868/915MHz ISM band,globally license free. Maximal output power100mW(20dBm),output power adjustable between 1-20dBm Sensitivity -117dBm Supply current for Tx 100mA@20dBm, 40mA@14dBm Supply current for Rx 25mA Low current sleep mode 1uA Standard RS485 interface Operation frequency can be configured, acceptable for several modules working in different frequency with no disturbance on each other. Optional for frequency deviation and receiving ISM bandwidth, users can be modulated by software. Easily use, auto exchange on communication & transceiver Communication speed 1.2kbps -115.2kbps,can be modulated through software Afford ENABLE control signal,user self control work duty cycle RSSI function With LED indication Longer transmission distance,over 1Km in open air Tuning free Accord FCC,ETSI standard;
