The extended settings additionally control the behaviour of the exporter. 

Encoding - Either UTF-8 or ASCII.

Min. Seconds Between - Define a minimum time in seconds between each record being sent.

Max Queue Length - The maximum queue size allowed in the buffer, the buffer is first in, first out - so the earliest passings will be dropped if the queue reaches the maximum length. 

Processing Delay -  Define a delay for x seconds after a read before passings to be exported. This can be set to avoid sending multiple alerts when participants are read multiple times at a timing point.

Ignore Before / Ignore After - Define a minimum and maximum time for passings to be exported. 

Connect Message - Define a custom message string which should be sent when starting the exporter (e.g. an authentication token).

Start in Paused Mode - If enabled then the exporter will be paused when started.
