Firmware that contains the unique personality for a system or device. A
codeplug is programmable and allows changes to system and unit
parameters. See also firmware.
A device that encodes or decodes a signal.
See Customer Programming Software.
Software with a graphical user interface containing the feature set of an
ASTRO radio. See also RSS.
See digital-to-analog conversion.
See digital-to-analog converter.
Definition for device (such as radio) data communications using the
RS232 protocol. The correct data communication wiring requires the
device's TX pins (output) to connect to the RX pins (input) and the RTS
pins (output) to connect to the CTS pins (input). It is incorrect to attach
device pins having the same name to to each other.
Data terminal equipment; for example, a computer.
See Data communication equipment.
A pre-defined set of parameters.
Refers to data that is stored or transmitted as a sequence of discrete
symbols from a finite set; most commonly this means binary data
represented using electronic or electromagnetic signals. See also
analog.
Conversion of a digital signal to a voltage that is proportional to the input
value. See also A/D.
A device that converts digital data into analog signals. See also ADC.
A type of digital communication that utilizes privacy call, as well as
memory channel and busy channel lock-out to enhance communication
efficiency.
A microcontroller specifically designed for performing the mathematics
involved in manipulating analog information, such as sound, that has
been converted into a digital form. DSP also implies the use of a data
compression technique.
Object code executed by the Digital Signal Processor in an ASTRO
subscriber radio. The DSP is responsible for computation-intensive
tasks, such as decoding ASTRO signaling.
