ETHERNET:
The Ethernet port is used for programming the device and for MQTT communication.
The Ethernet connection must be made using Connector2 of HD67939-B2 with at least a Category 5E cable. The maximum length of the
cable should not exceed 1 m. The cable has to conform to the T568 norms relative to connections in cat.5 up to 1 Mbps. To connect the
device to an Hub/Switch is recommended the use of a straight cable, to connect the device to a PC is recommended the use of a cross cable.

NEW CONFIGURATION / O EN CONFIGURATION:
The “New Configuration” button creates the folder which contains the entire device’s configuration.
A device’s configuration can also be imported or exported:
To clone the configurations of a Programmable “CAN / MQTT - Converter” in order to
configure another device in the same manner, it is necessary to maintain the folder and all
its contents;
To clone a project in order to obtain a different version of the project, it is sufficient to
duplicate the project folder with another name and open the new folder with the button
“Open Configuration”.

CAN:
This section is used to define the main parameters of CAN line. The means of the
fields are:
In the field “Baudrate” the baudrate for the CAN line is defined.

In the field “Keep Alive (seconds)” the delay with which the Keep Alive
message is sent on MQTT is defined;
If the field “Clean Session” is checked, the last MQTT messages are deleted
by the Server and the Client in case of missing ACK. If unchecked, the Server
and the Client hold the last MQTT messages and, in case of incorrect
disconnection or missing ACK, they try to send again them since all the ACK
messages are exchanged correctly (valid only for QoS 1 and QoS 2);
If the field “Will Flag” is checked, the converter will publish the Will topic at
the connection to the Server. With this feature, in case of incorrect
disconnection, the Server will publish this topic to all the MQTT Clients that
subscribed it;
In the field “Topic Name Will” the topic used for Will message is defined;
In the field “Message Will” the payload of the Will message is defined;
In the field “Retained Will” the converter will send the Will message with Retain flag enabled. In this way, the Server will hold the
last Will message;
