A type of IC package characterized by solder balls arranged in a grid
that are located on the underside of the package.
Controller Area Network protocol. The CAN cable is the remote
communications cable which provides audio, data, and power signaling
information between the Control head and the Transceiver.
Control Head Interface Board. Used to provide functionality /
connectivity between the CHUC and control head.
Control Head Universal Connector. A separate board which provides
connectivity to the CHIB and control head.
See coder/decoder.
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 Constant Envelope 4-Level Frequency Modulation.
Also referred to as a 4-carrier modulation format where the carrier is
shifted in frequency at a particular rate (time) to a particular location
around a center frequency. This allows for each of the 4 "states" to
represent a binary number. Each state is a "DiBit" or "Symbol" which
contains two bits of information
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 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.
