Data streaming on a party-line (RS-485 multiple units) is automatically suspended when
you send the “SLEEP” command, and is normally suspended when you “CONNECT” to
any unit on the party line. You can tell a unit to “output while in connect” using the “Set
up Port …” menus (described below) so the unit will continue to data stream, except while
you are in the menu system. A unit with a unit number of zero will automatically “output
while in connect.”
A reading is a measurement such as level or volume. A data set is all of the readings being
sent by a particular unit. By default, a NEWLINE is sent after each reading. A HOME
and a CLEAR are sent after each set. This causes the data to update at the same place on
the screen.
