1. INTRODUCTION
The WAVECARD equipment acts ike a RS232 Radio frequency gateway.
This device is driven through a USART ink (RS232 or TTL) by a c ient app ication (ca ed HOST in the
continuation of this document) embedded on a microcontro er 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 ca ed Service Exchanges and are
main y used for insta ation and maintenance procedures.(cf. §4).
The purpose of this document is to present:
the ow eve of the exchange protoco to drive the Wavecard radio board through an
asynchronous seria RS232 interface (±12V) or comp iant with TTL eve (0-3V) ;
the e ectrica interface of the Wavecard radio board ;
the mechanica interface of the Wavecard radio board ;
This document serves as a specification to drive a DLL driving ibrary on PC environment in the case the
Wavecard radio board is used as a RF Modem either to be integrated in a existing e ectronic device or to be
driven by a specific CPU mother board.
This document is a so usefu 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 .

2. RS232 SERIAL PROTOCOL PRESENTATION
This protoco is dedicated to an asynchronous RS232 or TTL ink between the host and the radio board.
➢Transmission format :
8 bits data,
1 stop bit,
no parity
➢Transmission speed : 9600 baud (contact us for other speed : mar[email protected]m)
2.1- Exchanges principle
The host or the radio board can take the initiative of the exchange. Neverthe ess in the high majority of the
cases, the host wi take the initiative.
Fig 1 – synoptic of the exchanges between a WavePort modem, and its host
2.1.1 - Low level acknowledge
In a the cases, the seria frames exchanged between the host and the radio board are managed by an
acknow edge mechanism.
A minimum atency time of 1 ms must be respected between the frame reception and the corresponding
acknow edge emission in order to respect the radio board processing time after a frame reception.
If the Acknow edge frame is not received by the initiator, it can decide to re-send severa times the frame
(retries mechanism). The RF defau t setting is :
Time-out = 500 ms
repetition number = 3

Document : CS-SUP-MUTI-WPORTAPP-E02.sxw
2.1.2 - Request/ Response principle
Some exchanges need a Request/response mechanism.
In this case , an high eve acknow edge (RES prefix command) is initiated by the RF board fo owing the
request frame (REQ prefix command) sent by the host.
The re uest frame are identified by REQ_XXX_XXX
example : REQ_SEND_FRAME
The high level acknowledge frame are identified by RES_XXX_XXX
example : RES_SEND_FRAME
In this examp e, from the request transmitter side, the frame RECEIVED_FRAME is the response associated
to the request REQ_SEND_FRAME.
The high eve acknow edgement of the request is identified by the RES_SEND_FRAME frame.

2.2- Exchanged frames format
2.2.1 - Wake Up and synchronization mechanism
In the purpose to optimize power consumption, the Wavecard is in a STANDBY mode and is wakening up
either :
periodica y to po a radio activity ;
on a seria frame reception coming from the host equipment.
A synchronization character is needed before the data in the seria frame to give time to the radio board to
wake up. This character is in hexadecima notation : 0xFF.
To be homogeneous, the radio board precedes as we its frames emissions with this synchronization
character.
2.2.2 - Frame description
The frames format is standardized as fo owing :
SYNC STX LENGTH CMD DATA CRC ETX

LENGTH
Note : - The frame minimum size is 6 bytes.
- The frame maximum size is 256 bytes.
The frame length (byte LENGTH) is computed from its own position until the included CRC. Bytes
SYNC STX and ETX are not included in the length.
To insure transmitted information integrity between the host and the radio board, a CRC code on 16 bits is
computed on overa frame data excepted STX and ETX characters ( the byte LENGTH is inserted in the
CRC).
The CRC code is computed by a division of the frame binary sequence by the fo owing po ynomia :
X16 + X12 + X5 + 1
A coding examp e is indicated on the next page.

CRC principle coding in C language :
#inc ude <iostream.h>
#inc ude <stdio.h>
#inc ude <string.h>
void main ( )
{
int Po y = 0x8408;
int g = 9;
unsigned int Frame [] = { 0x0B, 0x20, 0x43, 0x06, 0x01, 0x00, 0x00, 0x02, 0X01};
unsigned int Crc;
int j, i_bits, carry;
Crc = 0;
for ( j=0 ; j < g ; j++ )
{
Crc = Crc ^ Frame[j] ;
for ( i_bits=0 ; i_bits < 8 ; i_bits++ )
{
carry = Crc & 1 ;
Crc = Crc / 2 ;
if ( carry )
{
Crc = Crc ^ Po y;
}
}
}
printf ( “CRC = %x “, Crc);
}
The computed CRC is the following : 41D2 hexadecimal
Then LSB byte and MSB byte must be inverted before storage in the frame.
This example allows to compute a CRC on a fix frame length equal to 9.

2.3- Commands description
A the frames circu ating on the seria bus are formatted as described in chapter 2.2.2. The distinction
between the various frames is carried out via the 'CMD' fie ds representing the command (or the action) to
carry out.
The avai ab e commands types can be c assified in three parts :
Contro type commands
App icative commands
Service type commands
2.3.1 - Control type commands
This commands are used for the ow eve acknow edgement of the seria frames.
CMD NAME DESCRIPTION DATA FIELD FORMAT
0x06 ACK
Acknowledge Frame :
Sent by the receiver after reception of a Re uest /Response
frame type supported and understood.
No data field.
0x15 NAK
Non Acknowledge Frame :
Sent by the receiver after reception of a Re uest /Response
frame not understood.
No data field.
0x00 ERROR
Error frame :
Sent by the receiver after reception of a Re uest/response
frame understood but not supported.
Byte 1 :
0x01 : unknown command.
2.3.2 - Applicative type commands
The app icative type commands use the Request/response mechanism.
We distinguish two parts in the app icative type commands : the commands re ating to the parameter setting
and the configuration of the board ; and in addition the commands re ating to radio exchanges.
➢Commands relating to the parameter setting
Read, or update the interna parameters,
Read, or se ect the radio operating channe when FHSS is dese ected,
Read, or se ect the RF medium physica mode,
Read, or se ect the radio board emission power,
Activation of the Wavenis RF Asic RSSI thresho d autocorrection,
Modification of the seria ink baudrate,
Reading the RSSI eve of a distant equipment,
Reading the RSSI eve of the wavecard, fo owing an exchange with a distant equipment,
Reading the firmware version of the WaveCard,
Set the WaveCard into a test mode.
