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-1 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, PWR, PTT,
Mic & SPKR) and their appropriate match on the right
side of the diagram. For example, draw a line between
"PWR" pin on the left of JP-1 and the line that you
labeled "Accessory Voltage". The "PTT" pin should be
connected to the pin that you labeled "PTT" and so on.
An example of the Jumper Wiring Diagram for a
Kenwood TS-450 is shown below.

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 we provided for this purpose to avoid damage.
Install Jumper Wires – Now that you know where the
•
jumper wires go, all you need to do is install them! This
is best done by gripping them close to the end with
needle-nosed pliers. When pushing the wires into the
socket, be very careful not to bend them back and forth
or they might break. If you break a wire off in the
socket, there is no way to remove it. You will have to

have a new socket installed! This should not be an issue
if you are just a little bit careful. If you plan to change
the socket configuration often for different radios, you
might prefer to use a Dip Header for programming,
rather than wires. The Dip Header is a small terminal
block that you can solder the wires onto and then simply
plug into JP-1 when it's finished. This is by far the best
method if you need to switch radios often. The Dip
Headers are available from electronic suppliers like
DigiKey (P/N A103-ND), Mouser (P/N 544-16PT-02),
Radio Shack (P/N RSU11323763).
Once you have all of the jumpers installed, take a minute
to look them over. You might want to compare your
jumper settings to the sample settings shown in the
"Jumper Settings" section of the SignaLink CDROM. If
you are using the external "SPKR" or "PWR" input
jacks on the rear of the SignaLink, then you should NOT
have any jumpers going to the "SPKR" or "PWR" pins
on JP-1.
Measure Accessory Voltage – This step is normally
•
not necessary. But, if you have wired the accessory
power from your radio and are not sure if it is adequate
to power the SignaLink, you can easily verify the
voltage. First make sure the pc board is on an insolated
surface (no metal or wire clippings under board!). Turn
on the radio and press the Power switch on the
SignaLink. The green power led should illuminate.
Using your multimeter (volts) verify the voltage between
chassis ground and test point TP-1 near the left rear
corner of the SignaLink pc board (Figure-3).
voltage should be at least 6.75 volts for proper
operation. If the voltage is not adequate, you will need
to remove the power jumper on JP-1 and power the unit
externally (see "Connecting Power").
