connector. This cable brings all of the radio s signal lines
into the SignaLink, so that you can connect to any line that
is required (see note below on connectors with more than
eight pins). The SignaLink uses the radio s Ground, PTT,
Speaker Output, Mic Input, and Accessory Voltage lines.
These are the signal names that you will find on a typical
Mic connector. These signals are also available on most
Data and Accessory ports, but they are often labeled
differently. This will be covered in more detail below.
Because the location of these signals on the radio connector
varies from radio to radio, we have provided a
Programming Socket inside the SignaLink (see JP-1 in
Figure-4). The Programming Socket provides a convenient
way to route the various signals to the correct pin on the
radio connector. This is accomplished with press-in
jumper wires so no soldering is required.
Since the Programming Socket is a standard DIP-16 format,
you can also use a Dip Header Module for programming
rather than wires. This
soldering but does have the advantage that the resulting
module can be quickly changed to re-configure for
different radios. The Dip Headers are available from
Tigertronics as part number
electronic suppliers like DigiKey (P/N A103-ND) and
Mouser (P/N 544-16PT-02).
Signal Lines
Every installation requires connecting 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 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 Supply Voltage and Speaker Audio.
Supply Voltage has already been discussed in the section on
Connecting Power . If your radio has power available on
module approach requires
SLHEAD , and from
The
the connector then you will be instructed to connect it later
in this section. 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 a short (mono)
jumper cable from the External Speaker or Headphone jack
on your radio to the SPKR jack on the rear panel of the
SignaLink. 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 15 volts
@ 75ma. This is well 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 provided, or
you will be attaching your own 13-pin connector to our un-
terminated cable. In either case, 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.
Jumper Settings
If printed jumper settings were supplied
with your radio cable, then please skip to the Install
Jumper Wires section, and install the jumpers as shown on
the document. If you did not receive printed jumper
settings with your radio cable, then please check the
Jumper Settings section of the SignaLink CD to see if
information for your radio is available. Jumper settings for
the most common radios are included on the CD. If you do
not find the jumpers settings for your radio, then you will
need to follow the procedure below to install the jumpers.
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.

Lookup Pin-out
find the page 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
