Introduction
General
The Model 280 and Model 284 Digital Tone Remotes contain all the unique features and
audio performance required to handle critical communications in the public safety and
utility market segments. It is designed to provide the highest quality audio and most
dependable operation to fully support the rigorous demands of emergency, multi-operator
applications.
This family of Digital Tone Remotes is programmable so that they may be customized to
meet the needs of any dispatch center. They are EIA-compatible and interface seamlessly
to the most popular brands of base stations and repeaters, such as those from Motorola,
General Electric, and E.F. Johnson. They all support both 2-wire simplex and 4-wire
duplex operation. The Model 284 can support lines to four separate base stations or
repeaters.
Parallel Status Indication
Most tone remotes only display the last command sent by that particular remote. This
creates confusion in multi-operator applications where several remotes control the same
base station. This can be crucial for public safety dispatchers who need to know the exact
configuration of the base station without guesswork.
With the Model 280, however, the display of each remote can be updated when
any
remote
in the system sends a command to the base station. A Model 280 will show the latest base
station frequency as well as other parameters such as intercom and privacy.
The Model 284 is also capable of parallel status indication, and can provide parallel status
for all four base stations. Whenever the operator switches from one line to another, the
remote will update its display with the current status for that base station.
