VX-2500 SERIES
The 128-channel VX-2500 Series mobile transceivers are ideal for business and industrial applications. With 25 Watts of
power output, an easy-to-read 8-character invertible alpha-numeric display, nine programmable keys, and a host of signaling
formats, the VX-2500 will get your message through under the toughest conditions.
Alpha-numeric Display (14 Segments x 8 Digits)
The 8-digit Alpha-numeric display allows quick channel identification by the user,
and is easy to read from a wide range of viewing angles.
CTCSS/DCS
Subaudible (CTCSS) 50-tone Encoder and Decoder circuits are built into every
VX-2500, ensuring compatibility with modern repeater requirements.
applications requiring Digital Coded Squelch signaling, full-featured DCS Encoder
and Decoder circuits provide leading-edge protection from false decoding. Any
combination of CTCSS and DCS will be available on the same channel.
DUAL 2-TONE Decoding
For applications where a mobile may be receiving calls from more than one
dispatcher on a particular channel, the VX-2500 includes a built-in Dual Two-Tone
Decoder circuit.
DTMF ANI Encoder / ID Display
Automatic Number Identification (ANI) via an automatic DTMF Encoder is also
provided among the VX-2500’s versatile signaling capabilities.
DTMF Paging
DTMF Paging function is good for dispatch or network operations.
Versatile Scanning
A wide range of set-up options are available during configuration of the VX-2500,
to ensure compatibility with the operating requirements of your system’s users.
Audio Compander Included
For narrow-band channel applications, the built-in Audio Companding system
compresses the voice waveform during transmission, and expands it during reception,
allowing full-sounding audio despite the restricted transmission bandwidth.
Encryption (Optional FVP-25 required)
For applications requiring secure communications, the optional FVP-25 Paging/
Encryption Unit provides scrambling and descrambling functions.
Emergency Mode
When activated, the "Emergency" feature sends out the DTMF ANI, and cycles
between transmit and receive, to serve as an emergency beacon to alert the
dispatcher as to the need for immediate aid.
ARTSTM Feature
The Auto-Range Transponder System, a Vertex Standard exclusive, alerts the operator
when another ARTS
communication range. You can then advise the other user to move to a better location.

TOT, BCLO, BTLO Features
Among the most useful protection features of the VX-2500 are the transmitter
For
Time-Out Timer (TOT), Busy Channel Lock-Out (BCLO), and Busy Tone Lock-Out
(BTLO), to ensure efficient network performance at all times.
Programmable Front Panel Keys
Custom assignment of important functions to front panel keys is available at the time of
programming, to provide the most ergonomically-friendly transceiver available today.
Programmable Alert Tones
Among the useful set-up options for the VX-2500 is the capability to customize the
"Alert" tones generated from the transceiver, for ease of recognition by the user.
Rugged, Die-cast Construction
The VX-2500’s circuitry is housed within a
die-cast aluminum enclosure, which doubles
as a heat sink. This extraordinarily durable
construction ensures many years of reliable
operation, even in high-vibration installations
.
MIL-Spec Rated (MIL 810 C/D/E)
The ultra-rugged design of the VX-2500 Series enables it to be fully compliant
with the exacting specifications of MIL 810 C, D, and E, pursuant to the test
procedures documented below.
