Embedded Wireless Solutions RC1240/1280/1290
Narrow Band Multi-Channel RF Transceiver Module
Product Description
The RC1240, RC1280 and RC1290 RF Transceiver Modules are compact surface-mounted
high performance modules for 25 kHz narrow band FSK operation with embedded protocol.
The modules are completely shielded and pre-certified for operation under the European and
US radio regulations for license-free use. When used with quarter-wave antennas a line-of-
sight range of 2-4 km can be achieved at 433 MHz.
Applications
OEM equipment
Radio modems
Alarm and security systems
Point-of-sales terminals
Bar code scanners
Telemetry stations
Fleet management

Quick Product Introduction
How do I transmit data?
Send your data to the RXD pin on the module. Use the UART format with settings (19200, 8,
1, N, no flow control), use 2 stop-bits if CTS is enabled. Up to 128 bytes are buffered in the
module. The module will transmit the data when
the max packet length is reached
the unique end character is sent
the modem timeout limit is reached
The packet length, end character and timeout limit are configurable in-circuit.
How do I receive data?
Any received data packet with correct address and check sum will be sent on the TXD pin
using the same UART format as for transmit.
What about the antenna?
In most cases a simple quarter wavelength wire or a PCB track will do. Connect a piece of
wire to the RF pin with length corresponding to the quarter of a wavelength. For space limited
products, contact Radiocrafts and we will recommend the best antenna solution for your
application.
How do I change the RF channel or any other parameter?
To change configurable parameters, assert the CONFIG pin, and send the command string
using the same serial interface as for transmitting data. Parameters can be changed
permanently and stored in non-volatile memory in the module.
