DynaPCN 10-20-xx Ethernet Communication Protocol Rev. 1-4 Introduction

5 /

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.

NOTES:

• The DynaPCN acts as a “listening device” on TCP port 5400

• For commands that return a reply: always wait for the reply to be received correctly before

closing the communication

• All the parameters or the numerical responses (int and short) formed by more than one

byte (for example the output of gcounters, or the output of the function input0) follow the

ordering from LSB (Less Significant Byte) to MSB (Most Significant Byte ).

Example:

If gcounters replies with “99 01 00 00 E7 01 00 00” (there are two integer 4-byte counters),

the result will be as follows:

Type of counter

Result in hexadecimal format

Result in decimal format

00 00 01 99 (0x0199)

409

OUT

00 00 01 E7 (0x01e7)

487

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 you send, always 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;

}

able 3. Error Codes and their meaning

Error code

Meaning

No issues

One or both video sensors partially occluded

One video sensor completely occluded

Both video sensors completely occluded

Right video sensor obscured

Left sensor obscured

Both video sensors obscured

High lighting difference between right and left video sensors

20, 24, 28

High lighting difference between right and left video sensors, and both video sensors occluded

The difference between occlusion and obscuring is the following:

• Occlusion: condition in which an object placed near one or both video sensors partially or completely covers them.

This condition may occur in the typical case where a video sensor is covered by a hand, an opaque adhesive, or

hewing gum. If this condition persists for a sufficiently long time, it is necessary to verify that there are no objects

placed on the video sensors that prevent them from functioning properly

• Obscuring: abnormal low light condition. If this condition persists for a sufficiently long time, it means that the PCN is

working in an environment too dark for its configuration. It is necessary to check the intensity of the infrared LEDs and

consider whether to increase it.

1. Connect to the PCN

2. Set the current time and date

3. Enable diagnostic

4. Reset counters
