Ethernet Enabled Programmable TV/AV Controller Crestron CEN-TVAV
Programming Modes
The CEN-TVAV may be utilized three ways to perform different functions; Local
Processing, Remote Processing, and Mixed Modes. As shown below, the CEN-
TVAV and its supporting devices have been added to SIMPL Windows.
New SIMPL Windows’ Devices for Programming the CEN-TVAV
NOTE: Refer to “Leading Specifications” on page 7 of this Operations Guide for
the version of SIMPL Windows required to program the CEN-TVAV.
NOTE: The CEN-TVAV contains no NVRAM. It has “simulated” NVRAM,
meaning that conventional (volatile) memory is mapped into the NVRAM space.
When power is disconnected, the contents of memory are lost. Rather than restrict
the usage of NVRAM symbols (such as RAM, SMEM, etc.), the mapping allows
some SIMPL programs to use NVRAM for runtime calculations. Runtime
calculations are not essential if power is lost and are reset at startup (i.e. such as
putting names into an SMEM when using the QUE symbol).
NOTE: The CEN-TVAV also does not have a hardware clock. The clock must be
reset at startup.
NOTE: The compiler will detect usage of NVRAM symbols or DEVICE SYSTEM
(real time clock driver) and flag it in the error log as warnings when programming.
Local Processing Mode
In the Local Processing Mode, the CEN-TVAV is programmed to access and control
its local hardware ports. 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. From the Control Systems folder in the Device
Library select CEN-TVAV. Drag and drop the CEN-TVAV into System View and
the symbol appears as shown on the next page.
