Signal Types
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 signal connected there
will be an analog signal.
In SIMPL Windows, the signal types are color-coded as follows:
Digital = Blue
Analog = Red
Serial = Black
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 Crestron website (
Digital Signals
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 on/off or high/low,
recognized as two voltage levels. (Other common descriptors are active/inactive.)
Analog Signals
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

pan/tilt head controllers, and lighting dimmers.
