1-Way Wireless RF Touchpanel

Toggle Feedback
Toggle feedback is when the feedback of a button alternates between active and
inactive each time the button is pressed. As in the interlock, the toggle feedback
remains high even after the button is released, until the button is pressed again.
Because there is no way to communicate the state of the toggle button between the
panel and the control system by using that single button, Crestron models a toggle on
a one-way panel as a two-button interlock group. The button shown on the panel is
the first button. The second button (invisible, Crestron-created, not user-created) is
the original button's join number + 500, e.g. 1 and 501, 101 and 601, etc. Since there
are only 999 join numbers allowed by Crestron's RF protocol, a toggle button may
only have a join number of 499 or below. Be aware that you must not use the toggle
join numbers + 500 for other purposes. Crestron recommends that you keep toggle
buttons in one numeric range (such as 100-150) and then make sure you do not use
anything in the corresponding +500 range (600-750). When the user first presses and
releases the toggle button, the panel transmits the join number press and release. The
next time the user presses and releases the toggle button, the panel transmits the join
number + 500 press and release, and then continues to alternate between them. By
this method, Crestron knows that the user is explicitly turning the toggle on or
explicitly turning it off, so that the state on the control system and the state on the
touchpanel will match. The programmer must place an INTERLOCK symbol in the
SIMPL Windows program and connect both the join number and the join number
+ 500 to it. The feedback corresponding to the original join number should be used
to drive the logic corresponding to the toggle being turned on, and the feedback
corresponding to the join number offset by 500 is used to drive the logic
corresponding to the toggle being turned off. Refer to the following figure.

Duration Feedback
A button defined with duration feedback will remain active for a fixed period of time
as programmed in the Duration field. Active duration is defined by selecting
Duration as the feedback type, and entering a number of seconds in the Duration
field. The programmer should add an MV (one-shot) symbol to the SIMPL Windows
program, with the appropriate time parameter, as shown in the following figure.

Sequence Groups
In addition to button feedback, programmers can specify that a single button perform
a sequence of operations. The sequence can press other buttons and these buttons
may have durations to introduce delays. The virtual feedback generated by VT Pro-e
to the one-way panel will approximate as closely as possible the SIMPL Windows
program of multi button press feedback generated from a single button press
