VX-4000
- Introduction
Reliability,
ruggedness, and versatility: these are the essential elements
in a successful communications system. Vertex Standard VX-4000
provides the features, performance, and toughness to get your
message through under the most demanding public safety operating
conditions.
It's a perfect blend of rugged design, flexible signaling options,
superb ergonomics, and expandability, making the VX-4000 series
an outstanding choice for your future communications needs.
ONE RF DECK TO MULTIPLE HEAD CAPABILITIES
A single VX-4000 RF Deck may be controlled by two different
Control Heads, allowing control of the radio from more than
one location. Depending on the installation requirements,
both Control Heads may be connected directly to the RF Deck,
or the two Control Heads may be connected in a series "Daisy
Chain" configuration.
250 CHANNEL CAPACITY
Huge 250-channel capacity may be partitioned into as many
as 20 Memory Groups, with no limit on the number of channels
in each Group. A single radio may therefore be programmed
with channel sets for a number of different jurisdictions
or organizations.
PRIORITY SCAN
The VX-4000's versatile scanning system includes a Priority
Scan function, which provides scanning of all channels
(or channels within a Memory Group) while maintaining a
priority
watch on a particularly important channel. Scanning will
halt immediately, and operation will revert to the Priority
Channel if activity is detected on the Priority Channel.
GROUP
SCAN
To provide more efficient scanning, the VX-4000 provides
capability for scanning only within a particular Memory
Group. The channels you need to scan therefore will be
checked more
times per minute, ensuring that important calls are not
missed.
VOTING (RECEIVED SIGNAL STRENGTH) SCAN
In areas of heavy channel loading, or in areas where interference
from distant systems is often received, the VX-4000 may
be set up to respond only to signals exceeding a prescribed
signal level.
DTMF SIGNALING & DIALING
FEATURES
When used with the optional MH-53B7A DTMF Microphone, the
VX-4000 may be configured for both manual and Speed Dial
DTMF calling. All versions provide programmable PTT ANI
for business or fleet applications.
DUAL BAND CAPABILITY
Two VX-4000 Control Heads and RF Decks, on different bands,
may be "networked" to allow multi-band operation.
VHF, UHF, or VHF Low Band radios may be combined to meet
complicated communications requirements involving federal,
state, and local government and/or forestry operations.
CTCSS / DCS ENCODE+ DECODE
Field programming of the CTCSS tones or DCS codes is available,
allowing access to multiple systems or quick configuration
for multi-jurisdictional operations.
USER SELECTABLE TONES / CODES
High-performance Encoder/Decoder circuits for both CTCSS
and Digital Code Squelch are provided for access to
tone/code controlled systems..
BUILT IN 25 PIN (DB-25) ACCESSORY CONNECTOR
The VX-4000 includes a built-in standard DB-25 connector,
for ease of integration of the radio into your communications
system. The DB-25 connector includes a number of logic
status lines, Squelch state and level indicators, and
Data I/O connections.
Horn Alert and other accessories also can be connected
through the DB-25.
INTERNAL ACCESSORY INTERFACING
The VX-4000 Series is easily
interfaced to 3rd-party accessories. The optional CN-6
Interface Unit provides a quick interconnection
platform for signaling, control, and other accessory boards
used in public safety environments
