Features:

 

1.  Ultra low power transmission with 100mW as maximal transmission power.

 

2.  Requiring no any frequency, HAC-UEM transceivers work on ISM frequency band and carrier frequency is 433MHz.

 

3.  High anti-interference and Low BER (Bit error Rate)

 

Based on the Gaussian Frequency Shift Keying (GFSK) modulation, the high-efficiency forward error correction channel encoding technology is used to enhance data’s resistance to both transient 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.

 

4.         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 distances respectively is 2000m @1200bps, >1200m@9600bps and >400m@38400bps.

 

5.        Transparent data transmission

 

Transparent data interface used in transceivers 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).

 

6.        Multi-channels
HAC-UEM transceivers offer Multi-channels in one ISM frequency band satisfying various configuration of communication under user’s demand at the same time and avoiding the interference by other devices in the same locale. (Channels setting is set via serial port command, please see the concrete method in Page6)

 

7.        1 port with three connection methods
HAC-UEM transceivers provide 1 port with three connection ports: a UART interface of TTL level, a standard RS-232 port and a RS-485 port, but they are asynchronous, so only one port available once.

 

8.        Intelligent data control and no any complicated transmission programs required
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 by HAC-UEM transceivers automatically.

 

9.        Lower power consumption & Sleep function

 

The receiving current is <45mA, the transmitting current is <130mA @100mW (60mA@10mW), and the sleeping current is <5uA(Sleep mode controlled by user).

 

10.      High reliability, small and light

 

By using monolithic radio-frequency integrated circuit and single-chip MCU, the transceivers have little peripheral circuits, high reliability, and low failure rate.

 

11.       More options of configurable antennas for user different applications.
