Description
The HumPRC
TM
Series is the most complete
system to integrate bi-directional remote
control into many different applications. No
programming is required, and both module
and finished hardware options are available,
making it the easiest solution to implement.
The module provides long-range transmission
at 900MHz utilizing frequency hopping and
industry-standard encryption for secure and robust communications. The
HumPRC
TM
Series interoperates with Linx’s HumPRO
TM
family, making it the
only remote control solution that simultaneously supports data applications
for seamless integration with sensor and control IoT applications.
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.
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.
Housed in a compact reflow-compatible SMD package, the transceiver
requires no external RF components except an antenna, which greatly
simplifies integration and lowers development and assembly costs.
