Description

The HumRC

TM

Series transceiver is designed

for reliable bi-directional remote control
applications. It consists of a highly optimized
Frequency Hopping Spread Spectrum (FHSS)
RF transceiver and integrated remote control
transcoder. The FHSS system allows higher
RF output power and, therefore, longer range
than narrowband radios. It also provides
much more noise immunity than narrowband
radios, making the module suitable for use in noisy environments.

Eight status lines can be set up in any combination of inputs and outputs
for the transfer of button or contact states. A selectable acknowledgement
indicates that the transmission was successfully received. Versions are
available in the 902 to 928MHz and 2,400 to 2,483MHz frequency bands.

Primary settings are hardware-selectable, which eliminates the need for an
external microcontroller or other digital interface. For advanced features,
optional software configuration is provided by a UART interface; however,
no programming is required for basic operation.

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.
