SETUP
LOGIC INPUT & BUTTON DEFINITIONS SCREEN
The Logic Input & Button Definitions screen is used to assign specific 'recall preset actions' to the Logic Inputs (and remote control
buttons). Logic Inputs allow remote control of preset selection via external circuits, such as switches, contact-closures, active driver
circuits, and/or 'open-collector' logic outputs (see Logic Inputs on pg. 6). From the factory, Logic Inputs 1~8 are programmed to recall
presets 1~8 respectively. However, using the Logic Input & Button Definitions screen, each Logic Input may be assigned different 'recall
preset actions'. Left-clicking on a numbered button will select that Logic Input to be defined. Left-clicking on Preset Action will open a
drop-down menu of the available recall preset actions. Left-clicking the desired recall preset action will then assign that action to the
currently selected Logic Input. Since Logic Inputs are controlled by switches, contact-closures, etc., each Logic Input may be assigned
certain recall preset actions to perform when the switch is 'opened', and different recall preset actions to perform when that same switch is
'closed'. Left-clicking on Echo Character opens a drop-down menu, which allows the 'echo' character for the selected Logic Input to be
changed. This is the RS-232 ASCII character which will be transmitted via the Serial Port whenever that Logic Input is switched. From the
factory, no echo characters are assigned to Logic Inputs 1~8. Changing the echo character is used primarily for customizing remote
control commands amongst various RS-232 controlled products within a system (see RS-232 Control on pg. 8). NOTE: Unlike other
remote controls, the DDL12 Logic Inputs do not include a 'repeat' function. Therefore, a Logic Input in an 'opened' or 'closed' state will not
continuously repeat an echo character via RS-232 . Although the DDL12 does not accept infrared or wall-mount remote controls itself, it
®
can still receive echo characters (via RS-232) from other ADVANTAGE
products which are utilizing these types of remote controls. From
the factory, Remote Control Buttons have equivalent ASCII characters permanently assigned to them (see RS-232 Control on pg. 8).
Therefore, recall preset actions can be assigned to Remote Control Buttons in the same way they are assigned to Logic Inputs. Left-
clicking on Clear opens a drop-down menu, which allows recall preset actions to be cleared from the selected Logic Input (or all Logic
Inputs). Left-clicking on Default opens a drop-down menu, which allows recall preset actions to be set back to the factory default for the
selected Logic Input (or all Logic Inputs). Left-clicking on Try It causes the recall preset actions currently assigned to the selected Logic
Input to be performed by the DDL12. Left-clicking on Help provides additional instruction. Left-clicking on Close will close the Logic Input
& Button Definitions screen.
