SL4300 Series
SL4300
Embedded protocol • Easy to use
ISM/SRD band FSK transceiver modules
433 / 868 / 915 MHz
General Information
The SL4300 is a transceiver designed to simplify
implementation of radio functionality into products.
The modules have a built-in communication
protocol ( RSL232™ ) and are optimized for long
range performance and low cost. They can be
used in complex Meshnet applications, as well as
for easy replacement of wired connections.
The SL4300 modules are made for operation in
the standard ISM/SRD bands of 433/ 868 / 915
MHz, and comply or will comply with both FCC
and ETSI regulations.
The modules are available with internal chip
antenna or with connection for external antenna:

2. Product Description
The SL4300 is a series of radio modules that
make it easy to implement radio functionality into
products. The SL4300 series contains three
radio modules which operate on different
ISM/SRD bands. They are compact, surface-
mounted and high-performance modules. The
embedded RSL232™ protocol simplifies data
exchange and configuration of the modules for
radio communication, and helps ensure that the
configured module will comply with radio
regulations. The modules are certified for
license-free operation under European and US
regulations. When used in a line-of-sight
environment a range of 1–2 km can be achieved
at 433 MHz. The module can be set up to act as
an RS232 wire replacement.

4. Circuit Description
The SL4300 module is a RF transceiver with an
embedded communication protocol. It consists
of a high-performance RF transceiver and
RSL232™ communication controller.
The RF transmissions are packet-oriented. The
data packet contains error detection and
address information used by the communication
controller to maintain and verify data integrity.
The RSL232™ communication controller
handles data transfers through the UART
interface and the configuration of the module.
The UART interface in the module is
asynchronous, and allows two-way
communication with the host. It can also be
configured for handshake operation.
The RF transceiver FSK modulates the data to
be
transmitted
by
radio
frequency,
and
demodulates data that are received.
