Ultra Low Power Data Radio Module:
Ultra low power transmission with 10mW maximal transmission power.
Transceivers work on ISM frequency band and carrier frequency of 433MHz.
High anti-interference and low BER (Bit error Rate) - Based on the Gaussian Frequency Shift Keying (GFSK) modulation mode, the high-efficiency forward error correction channel encoding technology is used to enhance data’s resistance to both transient and random interference and the actual bit error rate of 10-5 ~ 10-6 can be achieved when channel bit error rate is 10-2.
Long transmission distance - Within the visible range, when the height of antenna is higher than 2m and the bit Error Rate (BER) is 10-3, the reliable transmission distance respectively is more than 800m@1200bps, >500m @9600bps and >300m @ 38400bps.
Transparent data transmission - Transparent data interface used in transceiver is for meeting many standard or nonstandard user protocols. Any false data generated in air can be filtrated automatically (
What has been received is exactly what has been transmitted
Multi-channel - these transceivers offer Multi-channels in one ISM frequency band satisfying various configuration of communication under users’ demand at the same time and avoiding the interference by other devices in the same locale. (Channels setting is set via serial port’s order)
3 serial ports with 3 connection methods - the module provides 3 serial ports and 3 connection methods, with COM1 as the TTL level UART interface, COM2 as the nonstandard RS-232 port and Com3 as the nonstandard RS-485 port (using software analogy as the logic of RS232 and RS485, the level of COM 2 is –0.7~5.7V having the same use method with the standard RS232/485 and the efficient drive distance is 2m.) Note: when the baud rate is more than 9600bps,only TTL interface available.
Large data buffer zone - The interface data rate is same with the RF baud rate: 1200, 2400, 4800, 9600, 19200, 38400, 56700bps. With format of 8N1/8E1/8O1, users can define by themselves. The module can transmit unlimited long data frames supporting flexible programming.
Intelligent data control requiring no any complicated transmission programs Even for half duplex communication, no any excessive programs required. All RF system data transmission/reception and other On-the-Fly conversion and control are performed automatically.
Low power consumption & sleep function - The receiving current is <25mA, the transmitting current is <40mA, and the sleeping current is <25uA.
High reliability, light and small - By using monolithic radio- frequency integrated circuit and single-chip MCU, the transceivers have little peripheral circuits, high reliability, and low failure rate.
