CHAPTER 1
Introduction
Overview
The C-2000 is a full featured single-channel, multi-format, and self-contained desktop radio control console. Its sleek and
modern look compliments any surrounding.
The C-2000 is a
DSP
(Digital Signal Processor) based design, allowing easy field programmability using the
DTMF
(Dual Tone Multi-Frequency) keypad on the front of the console. Unlike other manufacturers’ equipment, no
additional software is required to program the C-2000 console. Modifications and enhancements can generally be made
through software changes only. If the user determines they require a special feature enhancement, please contact the Radio
Dispatch Sales Department for cost and feasibility.
Initial line level adjustments are made via potentiometers allowing for ease of installation. Should additional adjustments be
required, they can be made in the programming mode.
AGC
(Automatic Gain Control) on the receive and microphone audio
paths help stabilize line level adjustments.
The C-2000’s modular design offers control of one (1) base station, along with selection of 99 frequencies. The line interface
offers crossmute capability and squelch control feature eliminating the unwanted noise that is generally associated when
monitoring a line.
The C-2000 accommodates a desk microphone along with a handset (or headset) as indicated on the side of the C-2000
console. In addition to the external microphone options, a built in panel microphone is available by pressing the
PTT
(Push-To-Talk) on the front of the panel. When a PTT occurs from any of the three (3) microphones, the others will mute
so as not to pick-up unnecessary ambient noise during transmission. When the handset is enabled and taken off hook, the
receive audio is transferred to the earpiece.
The console is normally used in conjunction with a matching Radio Dispatch 223 Series (or equivalent) tone-remote panel
located at the base station. The console is compatible with Motorola
1
, MA/Com Net Ericsson/GE
1
, and other tone-remote
control systems employing the industry-standard sequential tone-control format.
The console is connected to the mating panels by means of shielded voice-grade or better leased or private lines (including
microwave circuits). Metallic or DC continuity is not required.
