DX LCD Display Terminal
The DX LCD Display Terminal is a local user
interface for DX-9100 Series controllers. It is
designed for the operator or maintenance person
who needs a straightforward way to monitor and
adjust controller points. Information may be
presented graphically and in textual format. The
display can be used as a portable, hand-held unit,
or permanently mounted in a panel or on the wall
to monitor a single controller, or any one of up to
eight controllers by keyboard selection.
