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
controlling devices that do not have discrete settings, such as volume controllers,
pan/tilt head controllers, and lighting dimmers.
Serial Signals
Serial signals are much like analog signals, in that they, too, contain 16 bits of
information. However, whereas the value of an analog signal is used directly-to
control volume or temperature, for instance–the value of the serial signal is used as a
pointer to a location in memory that contains a string of characters. When a serial
signal is routed to a symbol, that symbol can identify the signal as serial rather than
analog and it will automatically look at the data it points to.
Thus 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.
TPS-4000 Input/Output Signals
The TPS-4000 symbol provides up to 4000 digital input and output joins, 4000
analog input and output joins, and up to 999 serial input joins. The programmer
selects the signal types by clicking on the appropriate button at the top of the Symbol
Detail view when programming the panel.
The following tables list and give functional descriptions for the touchpanel outputs
and inputs.

DESCRIPTION
Notifies control system of a button press on the
touchpanel screen (1 - 4000).
High/1 = Button being pressed
Low/0 = Button not being pressed
DESCRIPTION
Notifies panel of digital feedback (1 - 4000). This
can represent that a touchpanel button was
pressed or can be an actual device feedback, e.g.,
that power was turned on.
