Receive
audio is not
available
on the microphone
jack
of all radios. If
you
make
this connec-
tion
and are unable
to rcceive,
use the speakerjack on
the
rear
panel
of the radio as
a source of
receive
audio.
Your radio
may not require
a
plug
with three
connections, i.e.,
tip, ring, and sleeve. We suggest
you
use the
three-conductor
"stereo"
plug
wired
as shown, so
that
if
you
change radios to an-
other model
with this
same connection scheme, your
cable
will
be compatible without modifi-
cation.
Older Icom transceivers
which
use the eighrpin microphone
plug
may not have receive
audio
connected
to the microphone
jack
on
pin
8. In this case,
pin
8
is
unused. We suggest
you
make
the
connection as
diagrammed,
even
if your
radio does not
have receive audio
available at
pin
8.
That
way, if
you
change
to a newer model Icom
radio, the
cable will be ready to use with-
out modifications.
If
you
make
this connection
and are unable
to receive, use the speaker
jack
on the rear
panel
ofthe radio
as a source
ofreceive audio.
If
you
have
difficulty in locating
an eighrpin DIN
plug
fbr this connection,
a five-pin DIN may
be
used
in
its
place.
A five-pin
DIN has
all the required
pins
for
connections
to
ICOM HF rigs,
because
pins
6, 7, and 8 are not
used. The numbering
and
arrangement of the remaining
pins
is
unchanged.
In
most Ten-Tec
radios where
an FSK input
is
provided,
a
pull-up
resistor
to
a
positive
power
source is required
to
produce
proper
function
of the FSK keyer
in the radio.
Contact Ten-Tec
for
recommendations
on how
to add this resistor
to the radio
to
which you
are connecting.
This
connection is
appropriate
for use
at 9600 bps applications
with
your
radio in DATA
mode.
This
connection is
only valid with
PCB-88, DSP-1232,D5P-2232,
and PK-900
Radio Port 2.
Appendix
A:
Radio
Connec-
This
appendix
provides
radio
connection
information from
your
Timewave
data controller to approximately
400
different
models
of amateur
transceivers.
Each
radio listed
references
a connection
figure and
possibly
a
note
on connections.
Notes are below on this
page.
Connection
figures
appear following
the table of
radios. All
pin
type wiring
connections are
viewed
from
the wiring/solder
side of the
plug.
The wire
colors used
on the diagrams refer
to the wires
in the radio cables
supplied with
your
Timewave
data
controller. The
standard minimum
configuration
will allow
operating of all HF modes with
your
radio
set fbr SSB
operation. When wiring
infbrmation
refers
to
FSK
connections, these connections
allow
you
to
operate
your
radio in
the RTTY or FSK
mode, and
usually results in a
purer
transmitted signal and usually
allows using
narrow filters
that are not
always available when
the radio is
set fbr SSB operation.
