8. Working humidity: 10%~90% (relative humidity without condensation);
9. Antenna impedance: 50 ;
10. Size: 109mm×79mm×30mm ; Weight: 290g;
11. Inter-communication Models: ML-6901/ML-6902/ ML-6903/ ML-6905/ML-6906;
Other Features:
1. High anti- interference and low BER (Bit error Rate)
Based on the GFSK modulation mode, the high- efficiency forward error correction channel encoding technology is used to enhance data’s resistance to both burst interference 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.
2. Transparent data transmission
Transparent data interface is offered to suit any standard or nonstandard user protocol. Any false data generated in the air can be filtrated automatically (What has been received is exactly what has been transmitted).
3. High speed wireless communication and Large data buffer zone
When the RF baudrate is bigger than COM baudrate, allowing to transmit unlimited length data at one time, when the RF baudrate is smaller or equal to the COM’s, allowing the transmission of 255 Bytes data .
4. Intelligent data control and the user doesn’t need to prepare excessive programs
Even for semi duplex communication, the user doesn’t need to prepare excessive programs, only receiving/transmitting the data from the interface. Ml-6906 will complete the other operations automatically, such as transmission/receiving conversion in the air, control, etc.
5. High reliability, small and light
Single chip radio - frequency integrated circuit and single chip MCU are used for lessened peripheral circuits, high reliability, and low failure rate.
6. Watchdog monitor
Watchdog monitors the inner function, it changes the traditional product structure and also improve the reliability of our modules.
