16-Bit Integer - a unit of digital information comprised of 16 bits which may be interpreted as:
Unsigned:
0
to
65,535
(

–1) or
Signed:
−32,768
(

32,767
(

–1) value.
32-Bit Float
- a method of representing real numbers in a way that can support a wide range of
values..
Analog Signal
- any continuous signal for which the time varying feature (variable) of the signal is
a representation of some other time varying quantity, i.e., analogous to another time varying signal.
For example, in sound recording, fluctuations in air pressure strike the diaphragm of a
microphone
inducing fluctuations in current produced by its coil. This current is said to be an "analog" of the
sound.
Analog Input
- a method for measuring an analog signal.
Analog Output
- a method for producing an analog signal.
ASCII
- The American Standard Code for Information Interchange, is a character-encoding scheme
based on the ordering of the English alphabet. ASCII codes represent text in computers,
communications equipment, and other devices that use text.
Baud Rate
- A number related to the speed of data transmission in a system. The rate indicates
the number of electrical oscillations per second that occurs within a data transmission. The higher
the baud rate, the more bits per second are transferred.
Bias
- while scaling an analog input, the value added to offset the range. Example: range = 500,
bias = 100, analog input values scale from 100 (min) to 600 (max).
Bit
- a contraction of binary digit, is the basic unit of information in computing and telecommunications ; it is
the amount of information stored by a digital device that exists in one of two possible distinct states 1 or 0,
On or Off, etc...
Bit Rate
- RF data rate or rate that RF data is transmitted over-the-air (9.6k, 115.2k-900MHz or
250k-2.4MHz).
Byte
- unit of digital information in computing and telecommunications that most commonly
consists of eight bits.
Channel
- one of either 10 hopping sequences (900MHz) or 12 direct sequence channels (2.4GHz)
used to isolate radio communications.
COM Port
- a serial communication physical interface through which information transfers in or out one
bit at a time.
Configuration Port
- the COM Port used to configure a device.
Count All
- a method for increasing an unsigned 16 bit integer each time a discrete input is opened
or closed (2 counts).
Count High
- a method for increasing an unsigned 16 bit integer each time a discrete input is
closed (1 count).
Count Low
- a method for increasing an unsigned 16 bit integer each time a discrete input is
opened (1 count).
