1. INTRODUCTION
The WCAMODHEL is based on a Wavecard 25 mW.
The WAVECARD equipment acts like a RS232 Radio frequency gateway.
This device is driven through a USART link (RS232 or TTL) by a client application (called HOST in the
continuation of this document) embedded on a microcontroller or on a PC equipment.
The main features of the WAVECARD are :
to send a frame on the RF medium depending on Host equipment
to inform Host equipment about received frame
Exchanges between two WAVECARD require that each one is
connected to a Host device.
However, Wavecard can process some specific frames without Host
connected. These exchanges are called Service Exchanges and are
mainly used for installation and maintenance procedures.(cf. §4).
The purpose of this document is to present:
the low level of the exchange protocol to drive the Wavecard radio board through an
asynchronous serial RS232 interface (±12V) or compliant with TTL level (0-3V) ;
the electrical interface of the Wavecard radio board ;
the mechanical interface of the Wavecard radio board ;
This document serves as a specification to drive a DLL driving library on PC environment in the case the
Wavecard radio board is used as a RF Modem either to be integrated in a existing electronic device or to be
driven by a specific CPU mother board.
This document is also useful for the Waveport equipment. Waveport is a PC connected oriented RF modem
based on the Wavecard.
In this document the Host term is used to speak about the equipment or sub-equipment that is driving the
Wavecard radio board. The radio board term indicates the Wavecard equipment .
