By default, MQTT Engine is already configured to point to an MQTT Server at tcp://localhost:1883.  This means it will automatically connect to MQTT Distributor which is installed with it.  There are some other configuration parameters that could optionally be set.  The first is the 'Primary Host ID'.  This is a setting that is highly recommended and should be set on both MQTT Engine and any MQTT Transmission instances that are reporting in as well.  The ASCII string should match exactly on MQTT Engine and all MQTT Transmission instances.  The option to 'Block Node Commands' and 'Block Device Commands' could be unchecked if you want to allow tag writes at MQTT Engine to result in tag writes on the MQTT Transmission instances (i.e. remote tag writes).  Save the settings (SAVE-button at bottom of page) after making these changes.
