When all switches are in the "open" position (address 31), the Parallel488 is
in the Listen Only mode. This mode enables a TALK ONLY device, such as an
digital voltmeter or data logger, to send data directly to the Parallel488 without
requiring a controller.
2.2.2 Auto-Linefeed Selection
Switch SW1-6 selects whether auto-linefeed is selected. When SW1-6 is in
the "closed" position, no extra characters are added to received data. When SW1-6
is in the "open" position, the Parallel488 automatically inserts a linefeed character
into
the data stream after receiving a carriage-return. This feature is necessary
when both the data source does not send line feeds with each carriage-return, and
the receiving device does not insert linefeeds upon receipt of a carriage-return.
This feature is functional in both operating modes of the Parallel488. The
factory default condition is auto-linefeed disabled. It will become immediately
evident
that this
feature should be enabled if your printed material all appears on
one line.
