Model Number: SG-303(02) Brand Name: Safe Guard Key Specifications/Special Features: Long range two way RS232 RF radio data transceiver moduleModel: SG-303SG-303 wireless data transmission radio, is a long-distance wireless data transmission products. Its advantages of small size, metal shell, good shielding performance, strong anti-interference, the internal use of integrated amplifier, TCXO reliability device and a built-in watchdog that ensure its good stability and high reliability. Half duplex communication working mode which is more convenient for the user to provide two-way data signal transmission and detection and control functions. The send and receive time less than 50ms and timeliness. Suitable for wireless data acquisition, industrial control, the measurement and control of the oil field, watermark monitoring important industry.Features:
1) Power and sensitivity:
Radio frequency output power is more than 5W,
high receiving sensitivity -120dbm (1200bps);
-117dbm (2400bps,
-105dbm (9600bps)
2). Multiple frequency, to meet various customers' needs
Carrier frequency can be 220-220 MHZ, 450-470 MHZ.
3) High speed wireless communications and data buffer.
Air rate is greater than or equal to a serial port rate can continuous transmission infinite data, when the air rate is less than or equal to a serial port rate, temporary storage buffer then transfer.
4)Transparent transmission, convenience for the user.
Radio after receiving the data needs to be sent, launch will start automatically without user to send and receive control.
5) Low power consumption
Receiving current < 60 mA, emission current < 1.5 A, hibernation current < 1 ma.
