radio chassis and the pins numbered on the
Programming Socket (JP-1). JP-1 is a very convenient
place to probe since it is wired 1:1 to every pin on the
radio connector. You will be checking against the
numbers you recorded earlier from the Radio Manual.
Note that if your radio has a separate mic ground it may
have a slight resistance to chassis ground. Any other
ground pin should test very close to zero ohms. If you
do not get the expected continuity in this test, try
checking against the numbers in the reverse order (1=8,
2=7, 3=6, etc). It would probably be very helpful to
make a new table using the reversed number sequence
to avoid mistakes! This step should establish whether
or not the radio connector is reverse ordered and
allow you to correct the numbers on your table.
Once you are confident about the ground lines you can
move on to other pins. If your radio had Accessory
Power you should be able to turn ON the radio and use
your multimeter (volts scale) to test for power on the
appropriate pin of JP-1.
NOT use power from the radio, but this line can still be
used for verification purposes.
You can test the PTT pin as follows: First check the
pin with your multimeter (volts). You should see a
voltage on the PTT pin (5-12v) when the radio is ON.
You should be able to key the radio by grounding the
PTT line. For the sake of safety, you should ground the
PTT pin through a small value resistor (100-1000
ohms) in case it s not the pin you think it is! Be sure
your radio power is set to LOW and an antenna or
dummy load is connected for this test, as the radio will
go into transmit with the line grounded.
If the Speaker signal is available on the connector you
are using, then you can try attaching a speaker or
headphone to the appropriate pin on JP-1 to see if you
can hear audio. Note that you will NOT be able to hear
anything if the speaker source is a low level output
(usually the case on Data and Accessory ports). There
is no easy way to test the mic line but there will be little
doubt about it if the other lines are correct. The main
thing you are looking for here is to determine whether
or not the connector numbers are reversed on your
radio. If you have any unresolved errors, then you
should double check your numbering in the radio
manual again.

Draw Jumper Wires - Once you have verified your
pin-out and are comfortable with the results, you are
ready to label the lines in Figure-2 and draw in the
jumper wires. To do this, you simply need to draw a
line between the pins on the left of JP-1 (G, PTT, Mic
& SPKR) and their appropriate match on the right side
of the diagram. For example, draw a line between the
G pin on the left of JP-1 and the line that you labeled
Ground . The PTT pin should be connected to the
pin that you labeled PTT and so on.
installing the SignaLink on a Data or Accessory port,
then refer to Figure 1 for the correct signal names. An
example of the microphone Jumper Wiring Diagram
for a Kenwood TS-450 is shown in Figure 3.

VERY IMPORTANT NOTE! You are about to install
the jumper wires. The wires must be 24ga AWG or
you will damage the socket! It would be best to use the
wires that we provided for this purpose to avoid
damage.
