Radiocrafts RC232 Protocol Wireless Modules
 
The RC232™ Embedded RF Protocol is used in a vast range of products from Radiocrafts. These range from low cost high data-rate modules to true narrow-band solutions for long range. There a modules for all ISM frequency bands so selecting a module for deployment in a specific region of the world, or the world-wide operation is no problem.
 
The protocol handles host communication, data buffering, addressing and broadcasting and error check. It supports point-to-point, point-to-multi-point and peer-to-peer network topologies.
 

The RC232™ embedded RF protocol and command interface is the most easy-to-use protocol for bidirectional wireless transmission of data packets from a transmitter to a receiver.

Data entered on one side of the link is received transparently, byte by byte at the other side.

Each module in a network has a SYSTEM_ID (one byte) and its own UNIQUE_ID, UID (one byte) defined by the host processor. These are programmed into each module using the configuration interface and can be stored into flash memory for permanency.

Each module also has a default destination address, the DESTINATION_ID. This address will be added to the data packet if addressing mode is enabled. The use of addressing can be enabled with ADDRESS_MODE in the configuration memory, again with flash memory storage.

RC232 Protocol Features:

  • Complete MAC layer packet protocol
  • Transparent and buffered modes
  • Individual node addressing
  • Message 'broadcasting'
  • Error checking
  • 128 byte data buffer
  • Power saving schemes
  • Packet Receive Signal Strength Indication
  • Easy-to-use UART interface
  • RS232/422/485/USB compatible via external level shifter
  • Optional UART hardware handshake
  • Point-to-point, Point-to-multi-point & Peer-to-peer

For peer-to-peer networks where the Destination-ID and other parameters (Channel Number, Transmit Power) change frequently, parameters can be stored RAM, saving constant writes to FLASH memory. For other applications such as point-to-point (cable replacement) type solutions, storing parameters into FLASH memory can reduce or eliminate processor overhead.
