Description
The EVM-915-250 features the 250
Series transceiver module in a modular
approved solution. It is designed to greatly
simplify implementation of the 250 Series
module into a working design without the
complications of FCC testing.
The 250 Series RF transceiver module is
designed for reliable bi-directional transfer
of digital data over distances of up to 4 miles (6.4km) line of sight. It
implements a Frequency Hopping Spread Spectrum (FHSS) protocol along
with networking and assured delivery features. The module automatically
handles all radio functions resulting in a UART-to-antenna wireless link.
The module has a Universal Asynchronous Receiver Transmitter (UART)
serial interface that can be directly connected to microcontrollers, RS-232
converters or USB adaptors. All configuration settings and data are
accessed through the UART interface.
