Digital outputs may be configured to individually turn off if no command message is received to that
output for a certain period. This feature provides an intelligent watch dog for each output, so that a
communications failure at a transmitting site causes the output to revert to a known state. See
section 4.4 Changing User Options for further details.
The output circuit is connected to the appropriate pair of "DO" terminals. Each digital output circuit
includes a LED indicator which is lit when the digital output is active.
