DMX:
This section is used to define the main parameters of DMX line. The means of the
fields are:
In the field “ DMX ” the direction of DMX data is defined. If “IN”, the
converter will receive DMX commands, if “OUT” it will send DMX commands;
In the field “ Channel Number ” the number of DMX channels is defined.
MQTT:
This section is used to define the main parameters of MQTT line. The means of the
fields are:
In the field “ Server URL ” the URL or the IP Address of the MQTT Server is
defined;
In the field “ Server Port ” the port used for MQTT communication is defined;
In the field “ Client ID ” the Client ID of the converter is defined (if ned);
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;
In the field “ QoS Will ” the QoS type for Will message is defined;
