Features:
Large power transmission with the transmission power of
2W and 5W selectable.
The carrier frequency is 429~437MHz.
High receiving sensitivity, the maximum receiving
sensitivity is -120dBm@1200bps.
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.
Long transmission distance Within the range of
visibility, when the 10dBi antenna height is more than 10m, the reliable
transmission distance for the module with 5W is more than 20km (BER=10-2
/1200bps). Within the range of visibility, when the 5.5dBi antenna height is
more than 2m, the reliable transmission distance for the module with 5W is more
than 10km (BER=10-2 /1200bps).
By using the high quality components and high reliable
crystal, the working temperature is from -40℃ to
+80℃.
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).
Multi-channel The standard HAC-HM configuration provides
8 channels. If the user needs, it can be extended to 16/32 channels, meeting
the multiple communication combination mode of the user.
Three interface modes(TTL、RS-232、RS-485).
Large data buffer zone The interface baud rate is
1200/2400/4800/9600/19200/38400bps with format of 8N1/8E1 and user
self-definition.
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. HAC-HM will automatically
complete the other operations, such as transmission/receiving conversion in the
air.
HAC-HM can indicate the intensity of magnetic field, the
power source and the transmission and receive of data.
