Signal Types

Signals interconnect the various devices and logic symbols that comprise a SIMPL

Windows 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: 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: 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

-1). This 16-bit property makes analog

signals useful for controlling devices that do not have discrete settings, such as

volume controllers, pan/tilt head controllers, and lighting dimmers.

Serial Signals: 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.

Programming Modes

The C2N-DVP4DI may be utilized two ways to perform different functions: Local

Processing mode (master) or Remote Processing mode (Cresnet or Ethernet slave).

As shown in the following graphic, the C2N-DVP4DI has been added to SIMPL

Windows as a master or slave device.
