Tone Remote

1 General
Unless noted, this manual refers to DSP-223 operating software 2.6.
The VegaDSP-223 tone-remote adapter provides remote control of two-way-radio base stations using
any Vega tone remote consoles. The DSP-223 is also compatible with other consoles using the industry-
standard sequential tone-keying format.
The DSP-223 connects to the tone remote control console(s) using any voice-grade transmission medium
such as a microwave link, a leased telephone line, or a twisted-pair 600-ohm line.
All DSP-223s are capable of decoding the PTT (push-to-talk/transmitter-on) tone sequence and the voice-
plus-tone signals during transmission. Control tones in the voice-plus-tone signal are filtered from the
transmitted voice. All models are prepared for jumper-plug conversion from two-wire-line operation to
four-wire-line operation. In the four-wire mode, the panels are full duplex capable.
The DSP-223 provides the following features:
PTT Relay
Monitor
Relay
99-digit
display
PTT, Monitor, and Power LED indications
F1 and F2 Relays (programmable to any function tone or Revert to F1)
6 digital outputs for channel selection, completely programmable per function tone
CTCSS generation (64 frequencies)
Hardware and software gain control
Local handset port for monitoring activity and transmission back to base or to radio
Front panel test points and level set potentiometers
RS-232C port on front panel for configuration via Windows application
Two PTT modes and three monitor modes
Eight selectable PTT frequencies
Ability to pass-through to a second tone adapter with 400ms built in delay line
Relays can be placed in any of four groups for separation of function
Single Function tone recognition (16 function tones)
Dual function tone recognition (100 function tones)
Morse Code Encoder for Automatic station identification
Automatic Gain Control
Function Tone lock-out
RX Audio Squelch

3.5kHz Low Pass Filter
All audio inputs and outputs are transient protected.
The DSP-223 line transformers are not designed to operate on lines carrying direct current. If a DC
voltage is on the line, isolate with external capacitors. If the line termination must conduct direct current,
install a 600:600-ohm transformer designed for the current involved.
