Signal Types
Operations Guide – DOC. 8170A
Signals interconnect the various devices and logic symbols that comprise a SIMPL
program. Signals can be one of three types: digital, analog, or serial. For any given
signal, the signal type is determined by its driving source. That is, if the symbol that
drives the signal has an analog output, then, by definition, the connecting signal is
analog.
In SIMPL Windows, the signal types are color-coded as follows:
Digital = Blue
Analog = Red
Serial = Black
Undefined/Other = Green
NOTE: "Other" signals are a combination of the three basic types (e.g., many
symbols accept either analog or serial signals where the combination is shown as a
green signal). The signal type is displayed on the Status Bar when the signal is
highlighted.
For additional information, refer to Doc. 6120, Crestron SIMPL Windows Symbol Guide. It
may be downloaded from the Downloads | Product Manuals | Software section of the Crestron
website (www.crestron.com).
Digital Signals (4000 maximum)
A digital signal contains one bit of information and usually takes on one of two
values: 1 or 0. These two digits can represent the logical values true and false, and
they can be represented in an electronic device by the states of on/off, high/low, and
recognized as two voltage levels (Other common descriptors are active/inactive).
Analog Signals (4000 maximum)
Unlike digital signals, analog signals can vary continuously in value, in the same
manner as a parameter such as volume, temperature, or pressure. Analog signals
contain 16 bits of information, which means that this type of signal can have values
ranging from 0 to 65535 (2
controlling devices that do not have discrete settings, such as volume controllers,
pan/tilt head controllers, and lighting dimmers.
Serial Signals (999 maximum)
Serial signals are used to facilitate the transmission of serial data (strings of
characters). These signals can be generated by incoming data on a COM port or by a
symbol that has a serial output, such as a serial I/O symbol.

Converting Programs and Modules Created for Other

Systems
SIMPL Windows can convert a program created for another type of control system
by simply changing the target to a CNX-DVP4.
To do this, you can open a SIMPL program that contains a control system other than
the CNX-DVP4, and then replace the existing control system with the CNX-DVP4.
That is, drag the CNX-DVP4 from the Control Systems folder onto the existing
control system in System Views, and click Yes when prompted to confirm the
replacement.
If the program contains SIMPL+ or User modules, the conversion might generate
error messages. This is because modules and programs often contain symbols with
"ambiguous" signals. For example, the inputs of the Serial to Analog symbol can be
