A with a span of 5 volts and an offset equal to 0 volts. Also, refer to “Power
Up/Reset Voltage Adjustment” on page 2 and make sure jumper X1 is set to 0%. If
the jumper is set to 50%, the symbol in the dotted box must be used to initialize
values upon start up or reset.
Block Diagram of System Incorporating a CNXAO-8
The first output, A1, provides a full output range from 0 to 5 volts. As a result, the
user can ramp up or down to any voltage in the five-volt range. The second output,
A2, produces half the range of A1, because the appropriate signal is passed through a
scaler. Thus, the user can only ramp to any voltage between 0 and 2.5 volts. The
third output, A3, provides six distinct output voltages. The appropriate signals passed
through an initializer produce six incremental one-volt outputs that the user selects
with the proper touchpanel button.
How to Create the Program
Configuration Manager
Use the Configuration Manager workspace (
Project | Configure System
) in SIMPL
Windows to select and configure all the devices that need to be included into the
system. For this example, from the Control Systems folder in the
Device Library
select CNMSX-AV with a card cage. Add a CT-3000 from the Touchpanels (Wired)
folder; the touchpanel NET ID must be set to 03, shown below. Drag and drop the
CT-3000 onto
Net Device (Slot #8 on the CNMSX-AV).
NOTE:
SIMPL Windows v1.30.01 or later is required to program the control
system containing a CNXAO-8. If using an earlier version of SIMPL Windows,
Crestron recommends a SIMPL Windows and operating system upgrade. The latest
version can be obtained from the Software Downloads page (Simplwin Library) of
