Detailed Jumper Installation Procedure - Tigertronics SignaLink USB Installation & Operation Manual

If you do not find the jumper settings for your radio listed
on the SignaLink CD or our web site, then follow this step-
by-step guide to install the jumpers for your radio.
Signal Lines - Every installation requires connecting the
SignaLink to at least three pins on the radio s Mic, Data, or
Accessory connector. On the Mic connector these are Mic
Input , PTT , and Ground . On the Data or Accessory
Port, these same basic signals are used, but they are usually
labeled differently. The table in Figure 1 shows the
common Mic signals and their Data / Accessory port
equivalents. Please refer to this table if you are installing
the SignaLink USB on your radio s Data or Accessory port.
Mic Signal Data/Accessory Port Signal
PTT (Push-To-Talk) Standby, PKS, or Packet Standby
Mic / Mic Input TX Data, Data Input, PKD, or
Mod In
AF Out / Speaker RX Data, Data Out, RXD, or
RX Audio
PTT GND PTT Ground, Chassis Ground
Mic GND Signal GND, Mic GND
Figure 1 - Data / Accessory Port Signal Names
Note that many radios actually have multiple ground
connections (Mic Ground, PTT Ground, etc.).
Programming Socket has multiple ground (G) connections
for this reason. On many radios the Mic, Data, and
Accessory connectors also provide access to Speaker Audio.
If Speaker Audio (or the equivalent Data / Accessory Port
signal) is not available from the connector on your radio,
then you will need to install the provided mono cable from
the External Speaker or Headphone jack on your radio, to
the SPKR jack on the rear panel of the SignaLink USB. If
this signal is available on the connector, then you will
connect it later in this section.
Before proceeding with jumper installation you should
verify in your radio manual that the radio PTT requirements
do not exceed the specifications of the SignaLink keying
circuit. Verify that the PTT is Grounded to make the
radio transmit and the PTT signal does not exceed 3 Amps
at 90V. This should be within the ratings of all modern
radios but could be a problem on some older rigs. If your
radio exceeds these specifications or requires some other
keying arrangement, then you will need to key the radio
using a low voltage/low current relay. Please feel free to
contact Technical Support if you need assistance with this.
Connectors With More Than Eight Pins
installation procedure in this manual is for use with radio
connectors that have 8 pins or less. If you are installing the
SignaLink on a 13-pin Accessory port (currently the only
radio connector with more than eight pins), then you will
either be using a fully assembled cable that we have

jumper settings and/or special instructions for installing the
connector and jumpers were included with the radio cable.
Please follow those instructions instead of the procedures in
this manual.
Identifying Jumper Locations - Identifying the jumper
locations for your radio is a two-step process. First we will
identify the pin-out for the radio connector, and then we
will verify that it is correct. The verification process is very
important since incorrect wiring could damage your
equipment. The final steps will be to draw a wiring
diagram using Figure-2 and actually install the jumpers.

that identifies the pin-out of the Mic, Data, or
Accessory connector that you are going to use. Using
the manual, identify the pin numbers assigned to the
following signals, and record them below. Note that
the signals found on radio Data and Accessory ports
will likely be labeled differently from those shown.
Please refer to the table in Figure 1 for the equivalent
Data / Accessory Port signals.

** Note that some radios only have one ground pin.
** Speaker Audio is not always available.

convention for their connectors. This is especially true

verification process could ward off a major disaster
when you turn on the power! This procedure verifies
that the pin numbers, which you just identified in the
radio manual, do in fact match the numbers identified
on the Programming Socket. The easiest way to do this
is to use a multimeter to verify some of the more
important lines.
make sure that the radio power is OFF, that there are

supplied cable is connected between the SignaLink and
the radio.
Note that you should not find the lines scrambled .
They will either be in the correct order or they will be
completely reversed (pin 1=8, 2=7, 3=6, etc). First
check the Ground pin (or pins) recorded earlier. You
can do this by checking for continuity between the
