INFORMATION
The
IC-725
can
be
connected through
a CT-17CI-V
LEVEL
CONVERTER (optional)
to a
personal
computer
equipped
with
an RS-232C
port. Icom Communication
Interface
-
V
(Cl-V) controls frequency, mode, memory
channels,
etc.
•
CT-17
CONNECTION
Up
to four
Icom Cl-V
transceivers
can
be
connected
to
a personal
computer
equipped
with
as
RS-232C
port.

CONDITION
Transmitters and
receivers using
the
Icom
Cl-V
System
exchange
serial information
in
the
packet
format.
The
contents of
a data packet
can be changed
by diodes
D2
~
D4,
D57
~
D63 and
D64 on the
MAIN
UNIT.
See diagram
at right
below for
the location of
these
diodes.
•
Baud
rate
Baud
rate
is
the
data
transfer rate.
The
standard
Icom
Cl-V
baud
rate is
1
200 bps.

•Address
You
can
set an
independent
address for
your
IC-725.
The
IC-725
has the
address of
28H
(40)
as a default
value.
Figures marked
with an
H are
hexidecimals
and
bracketed
figures
(
)
are
decimals.

•Transceive
Transceive
operation
is
possible using
the
IC-725
with
another
transceiver
such
as the
IC-781.
Either
transceiver
can be used
as the
transmitter
or receiver.
