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.
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 connector.
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.
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.
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.
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.
VERSATILITY
ONE RF DECK TO MULTIPLE HEAD CAPABILITIES
DUAL BAND CAPABILITY
MULTI CONFIGURATION SYSTEM
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.
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.
