HopNet RS-232 Serial ModBus Radio
Frequency Hopping Spread Spectrum reduces the vulnerability of a radio system to
interference from jammers and multipath fading by distributing or spreading the
signal over a larger region of the frequency band.
The fade resistant, HopNet frequency-hopping technology employs up to 75 channels
and switches channels over 100 times a second to achieve high reliability throughput.
HopNet Data Integrity
An on-board 3 KB buffer and error correcting over-the-air protocol ensure data
integrity even in the presence of weak signals or jammers. The serial interface
handles both data and control of asynchronous data rates of up to 230 Kbps.
Flexible Power Management
The power can be set at 10 milliwatts or 100 milliwatts using the included software.
Reduced power can reduce the size of the coverage zone, which may be desirable for
multiple network indoor applications. You can also place the transceiver module in a
power-save mode, which enables smart power management. Smart power
management allows a remote unit to drop into a lower current standby mode during
transmission or receiving gaps. This feature also allows HopNet products to be used
in various countries where the output power requirements may vary due to regulation.
