RC232 User Manual (ver 2.01)
RC232 USER MANUAL
1 Introduction
1.1 Quick Start
The RC232
™ Module has a UART interface that is used for both packet data and module configuration. Use the
UART format with settings (19200, 8, 1, N, no flow control).
How do I configure the RF power, RF channel or any other parameter?
To change configurable parameters:
1. Assert the CONFIG-pin by pulling it low. This will take the module into configuration mode. More about
configuration mode is found in chapter 2.1
2. Use special commands to access the configuration registers and test modes. All the commands for the
configuration are found in chapter 2.2
3.
Exit from configuration mode by sending the ‘X’ command.
4. Start using the module as normal in packet mode. In some cases you need to reset the module for the changes
to take effect. Details about sending and receiving packet data is found in chapter 2.3.
How do I transmit data?
Send your data to the RXD pin on the module when the module is in normal mode (not CONFIG mode)
How do I receive data?
Any received RF data packet addressed to the receiving module will be output on the TXD pin when the module is
in normal mode (not during SLEEP or CONFIG modes)
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.
Radiocrafts also offer an Application Note on tuning a 169 MHz antenna in AN025, found here:
