Description Optional field (12 characters). Provides an additional description of
the channel that forms part of the channel name. Should always be
used with External Input channels to uniquely name the channel.
(“Channel Grouping and Naming” on page 8-7).
Channel Identifies the physical External Input used by this channel. This
number is identified on the rear of the TESLA LITE chassis. The list
only shows inputs which have not been assigned to other channels.
To get an overview of channel assignments, switch to the Channel
Tree view and look at the External Channel list.

input “glitch” filtering, which is approximately 700 microseconds.
Label Text to designate the active and inactive states. Default is "on" and
"off". Maximum 8 characters.

ate a combined record.

used to initiate wide area swing recordings and/or automated record

are closed momentarily for one second. Contact assignment is not
exclusive, allowing multiple triggers to activate the same contact.
