SignaLink "Plug & Play" Jumper Modules

Our new "Plug & Play" jumper modules plug into the SignaLink in place of the jumper wires that you would normally use to configure the unit for your radio.  This greatly simplifies installation and completely eliminates the possibility of installing the jumper wires incorrectly.  Swapping radios is also easier, as you simply unplug one module and plug in another.  All  jumper modules are compatible with the SignaLink USB, and most will also work with the older SignaLink and SL-1+.  Modules are currently available for the most popular radio configurations, and new modules for other configurations will be added soon.  Be sure to see the Installation Instructions and Common Questions below.

Which jumper module do I need for my radio?

Installation Instructions

The installation of the of the Plug & Play jumper modules is very simply, but you need to be careful that you don't bend any of the pins, or they may break off and become stuck inside the SignaLink's socket.  You should not have any trouble if you are just the slightest bit careful, but please note that broken pins and/or any damage to the jumper module or the SignaLink as a result of broken pins, is not covered under warranty (see note below).  Also, before installing any jumper module, please verify that you are installing the correct module for the radio and/or radio cable you will be using (see part numbers shown above!).  It is possible to damage your radio and/or the SignaLink by installing the wrong jumper module, or by installing it backwards, so please check carefully before proceeding.  The header pins used on all jumper modules are small and relatively sharp, so be careful that you don't stick a finger!

• Module Insertion - To install the jumper module, place it lightly on the SignaLink's JP1 jumper socket being careful to align the notch on the jumper module (white board outline) with the notch on the SignaLink's circuit board (white colored outline around the JP1 jumper socket).  Carefully look at each pin to make sure that all pins are centered in the socket holes, and then gently press down evenly on the module until it is seated securely in the socket.  Be careful not to press on any jumper  pins that might be mounted on the top of the jumper module (SLMOD13K, SLMOD8RI, etc.).

• Special Jumpers - Some jumper modules have one or two special jumpers that may need to be set for your radio (the PTT Configuration Jumper for the SLMOD13K module is a good example).  If this applies to the jumper module that you are installing, then be sure to see the jumper notes in the appropriate compatible radio links shown above.  

• Module Removal - To remove the jumper module, you will need to pull it straight out while being careful not to bend any pins in the process.  Be careful not to drop the module when it pulls loose from the socket!  We suggest gripping the module firmly with a pair of pliers, but any suitable tool can be used.  Some customers have removed the jumper module with a flat blade screwdriver by slowly prying up on both ends a little at a time until it is out.  This is ok ONLY if you lift each end up just the slightest bit (going back and forth from one end to another) so that the pins are not bent in the process.  If you remove the module this way, you need to go very slow and be sure that you don't lift too much on one end, or put pressure on any of the parts that are mounted on the SignaLink's circuit board.  

NOTE:  Each jumper module is carefully inspected before being packaged and shipped to insure that all pins are straight and the module is in perfect mechanical condition.  We use only high quality gold-plated pin strip header, and the header is designed specifically to plug into the machined socket on the SignaLink circuit board repeatedly.  However, it is important that the pins do not become bent during installation or removal of the module, or they may break and become lodged in the SignaLink's socket.  This is NOT covered under warranty and you would need to return the SignaLink to the factory to have the socket replaced, as well as purchase a new jumper module.

Common questions

• I have an IC-7000, FT-450, or an IC-746PRO and am using a resistor in place of the SignaLink's Mic jumper wire.  Can I use the SLMOD6PM jumper module? 
• Are the plug & play jumper modules compatible with all SignaLink models?
• Do the plug & play jumper modules supply power for the older SL-1+?
• Will you have plug & play jumper modules available for other configurations?

I have an IC-7000, FT-450, or an IC-746PRO and am using a resistor in place of the SignaLink's "Mic" jumper wire.  Can I use the SLMOD6PM jumper module?

We have received enough feedback on these radios now to know that most do NOT need the resistor, and possibly none of them do if you follow the suggestions on our troubleshooting page carefully. If you are currently using a resistor with your radio and would like to use the SLMOD6PM jumper module instead, then we suggest that you replace the resistor with the normal jumper wire and confirm that our suggestions work for your specific radio before ordering.

Are the plug & play jumper modules compatible with all SignaLink models?

Except for the SLMOD13K jumper module, all of the plug & play jumper modules for Data and Accy Ports are compatible with the SignaLink USB and SignaLink SL-1+.  The SLMOD13K jumper module will not work with the SL-1+ because it is physically too tall to fit in the case, although it is possible to cut the PTT jumper pins down to make it fit.  Note that the original SignaLink SL-1 works with Mic jacks only, and cannot be used with Data or Accy Ports.

Do the plug & play jumper modules supply power for the older SL-1+?

SLMOD6PM - Power is never available with this jumper module since it is not provided on the 6-pin mini-DIN Data Port connector of any radio.

SLMOD8PD - On this module the "PWR" pin is connected to the appropriate pin on the radio connector so that power to the SignaLink SL-1+ is supplied by the radio.  External power should NOT be applied to the SignaLink SL-1+ when using this module.

SLMOD13I - On this module the "PWR" pin is connected to the appropriate pin on the radio connector so that power to the SignaLink SL-1+ is supplied by the radio.  External power should NOT be applied to the SignaLink SL-1+ when using this module.

SLMOD13K - Power is never available with this jumper module since it is not provided on the Accy Port connector of any Kenwood radio.

SLMODK3 - Power is never available with this jumper module since it is not provided on the connectors used.

SLMOD5PD - Power is never available with this jumper module since it is never provided on the Accy / Packet Port connector of any Ten-Tec or Yaesu radio.

SLMOD8RI - This module has a "PWR" jumper that can be installed if power is provided by your radio (check your radio manual).  External power should NOT be applied to the SignaLink if the PWR jumper is installed.

SLMOD8RK - This module has a "PWR" jumper that can be installed if power is provided by your radio (check your radio manual).  External power should NOT be applied to the SignaLink if the PWR jumper is installed.

SLMOD8RY - Power is never available with this jumper module since sufficient power is not provided on the Mic connector of any Yaesu radio.

SIGNALINK USB USERS - As noted in our documentation, the SignaLink USB is always powered by the computer's USB connection so it NEVER needs external power.

Will you have plug & play jumper modules available for other configurations?

We are considering releasing plug & play jumper modules for other configurations (RJ-45 Mic, HTs, etc.).  These will be announced on the What's New? page and added here as soon as they are available.
