Feature of HR-1026 Low Power Wireless Transceiver Data Module:
1.Power and receiving sensitivity
The transmission power is<500Mw, Receiving sensitivity:          -123dbm(1200bps),-118dbm(9600bps)
Transmission current<300mA, Receiving current<25mA, sleeping current <20uA.
2. Modulation mode and Frequency
Modulation mode: GFSK, Frequency: 433MHz. Also capable of 450/470/868/915MHz.
3. 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.
4. Long transmission distance
Within the range of visibility, the reliable distance is (BER=10-5/9600bps)>2Km, (BER=10-5/1200bps)>3Km Standard antenna is 10cm,when antenna is 1.5m above ground in open area
5. Transparent data interface
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). The change time between receiving and sending is <10ms.
6. Multi- channel
The standard HR-1026 configuration provides 8 channels, if the user needs, it can be extended to 16/32 interface, meeting the multiple communication combination mode of the user.
7. Large data buffer zone
Interface baud rate is 1200/2400/4800/9600bps with format of 8N1/8E1 and user can define it by itself, It can transmit unlimited data when Interface baud rate is not bigger than air effective baud rate band.
8. 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. HR-1026 will complete the other operations automatically, such as transmission/receiving conversion in the air, control, etc.
9. 2 ports with three connection methods
HR-1026 transceivers provide 2 ports with three connection, ports: a UART interface of TTL level, a non-standard RS-232 port and a non-standard RS-485 port, which both are defined by user software (define it just by plugging out and in one short circuit device and then power on)
10. Three kinds of interface modes (TTL, RS-232, RS-485)
RS-232, RS-485 interface diversion chip, DB9 standard interface connector and special power connector are used.
11. Watchdog monitor
Watchdog monitors the inner function, so it can change the traditional product structure and also improve the reliability of our modules.

6. Standard configuration:
* One HR-1026 RF module
* A 9pin flat Connection Line.
* A whip antenna(about 10cm)
7Optional accessories:
* RS-232 interface programming connection Line. (Users can set the module parameters through the RS-232 of the computer easily)
* USB interface programming connection Line. (Users can set the module parameters through the  USB of the computer easily)
* Data transmission testing equipment. (User can test the module when select mode or actually use easily).
* Optional antenna (Users can according to their actually remands, choose their own antennas to achieve the optimal communications effect.
 NOTE:
* To achieve the optimal communications effect, please use less ripple power module, the maximum current of power should be greater than 1.5 times of the maximum current of modules.
* Only choose one interface of TTL、RS-485、RS-232,
* Baud rate classified:
   Interface rate: users can change through HRPRO.exe PC
   Air rate: it should be explained when users order product.
* Generally the module in receiving state, if the IDLE pin continuously connect low level (>200millisecond). At the same time the module can’t receive or transmit any data. Only When the IDLE pin hangs or in the state of high level (VH<3.5V), 150 ms later, the module will be in receiving state again. (If don’t need sleep function, the IDLE pin will be hang).
