1 Introduction
This document describes the Ethernet Communication Protocol between a user application and the
DynaPCN.
In this protocol, the DynaPCN is the server and the user application is the client.
The DynaPCN acts as a “listening device” on port 5400.
You can use an utility such as Packet Sender (https://packetsender.com/download
) to test the
functionality of the commands.
Each command is represented in the following way:
Command
Name of command
Command Description
Brief description of command purpose
Parameters
Format and type of possible parameter(s)
Parameters Description
Description of parameter(s) : permitted value, default ..
Returns
Format, type and meaning of possible returned parameter(s)
Sample Code
Example of code (only client side)
At the end of each command / parameter sent, include a “0x00” byte as terminator.
First of all it is necessary to create a communication socket between the user application and
DynaPCN.
Below you can find an example of client code to initialize the connection with DynaPCN.
#include <winsock2.h>
...
struct sockaddr_in my_addr_data,serv_addr_data;
SOCKET sock = socket(AF_INET,SOCK_STREAM,0);
memset((char *)&serv_addr,0,sizeof(serv_addr));
serv_addr.sin_family = AF_INET;
serv_addr.sin_port = htons(PORT);
serv_addr.sin_addr.s_addr = inet_addr(ADDRESS);
if(connect(sock,(struct sockaddr *)&serv_addr, sizeof(sockaddr)) == -1)
{
printf(“Unable to connect to %s", ADDRESS);
return;
}

2.10 ker_version
Command
ker_version
Command Description
Gets the kernel version
Parameters
Parameters Description
Returns
String containing the actual kernel version number (e.g. “2.1”)

2.11 pcn1001_status
Command
pcn1001_status
Command Description
Gets the status of the PCN and the diagnostic error code
Parameters
Parameters Description
Returns
2 unsigned char ( 1 byte) value.
The first byte indicates the presence / absence of issues:
• = 1 : No errors
• ≠ 1 : Error
The second byte specifies the type of error (error code): see Table 3.
The second byte has no meaning if the first byte = 1
Sample Code
unsigned char status,code_error;
SendString(sock,"pcn1001_status");
// gets the PCN status
Recv(sock,&status, sizeof(status));
// gets the error code
Recv(sock,&code_error, sizeof(code_error));
Table 3. Error Codes and their meaning
Error code
Meaning
1
Right sensor occluded
2
Left sensor occluded
3
Both sensors occluded
4
Right sensor obscured
8
Left sensor obscured
12
Both sensors obscured
16
High difference between right and left sensors
20,24,28
High difference between right and left sensors and both sensors obscured
The difference between occluded and obscured is the following:
• Occluded: This is a condition of complete masking of one or both sensors (example: a thick label attached on the sensor,
or sensor broken).
It should be better to verify if the PCN is ok
• Obscured: This is a lighter condition than the Occluded one. In this case the masking of one or both sensors is partial
and transitory. Generally this condition does not affect the counting.
