Introduction
Thank you for purchasing a RigExpert
TI-3000 USB Transceiver Inter face! We
did our best to make it power ful yet easy
to use.
RigExpert TI-3000 is a device for
operating phone, CW and digital modes
using personal computer with USB port.
It provides:
• Transceiver audio interface
Analog audio interface is a connection
to transceiver audio output (external
speaker connector or line output) and
transceiver audio input (microphone
connector or line input). Audio interface
enables operating digital modes, as
well as other useful functions (such as
measuring levels of a signal from the air)
by using a computer.
4
Input (main and sub channels) and
output volume levels are adjusted by
potentiometers on the front panel of the
device.
• CAT interface for various transceiver
models
CAT (Computer Aided Transceiver)
system provides control of transceiver
frequency, operating mode and other
functions by computer software. Normally, modern transceivers have serial
(with various signal levels) link providing
CAT interface.
A separate COM port is created for the
CAT system so the computer software
can communicate to the transceiver.
User’s manual
• PTT and CW output functions
Transceivers provide PTT (Push To Talk)
and CW (Continuous Wave) keyer inputs
to allow setting the transmitter on or off
and operating CW using external device
(PTT pedal, CW bug or paddle, terminal
node controller, or personal computer).
A separate COM port is created for PTT/
CW outputs.
• Squelch input
Some software, such as EchoLink, requires the interface to provide a squelch
input to detect if the radio channel is
busy.
In RigExpert TI-3000, the squelch input is
assigned to the DCD line of the COM port
used for PTT and CW outputs.
