Description
The HumDT
TM
Series transceiver is designed
for the reliable wireless transfer of serial
digital data. It consists of a highly optimized
RF transceiver and integrated data and
networking protocol. A frequency agile
over-the-air protocol provides better link
reliability than narrowband solutions while
providing faster synchronization and data
output than Frequency Hopping Spread
Spectrum (FHSS) algorithms.
The frequency agile protocol sends the same data on up to 4 channels,
providing the noise immunity benefits of FHSS without the overhead of a
hopping protocol. A serial command selects the number of channels as
well as which specific channels are used.
The module can achieve a line-of-sight range of up to 1,600m (1.0 mile).
The final range may be less depending on the regulatory requirements in
the country of operation and the antenna implementation.
The module’s UART interface is used for module configuration and data
transfer. 8 GPIOs can be used for analog and digital functions and are
controlled through the UART. Housed in a compact reflow-compatible SMD
package, the transceiver requires no external RF components except an
antenna, which greatly simplifies integration and lowers assembly costs.
