Our "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 as needed when you change radio cables.  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? Our SignaLink Product Guide lists the Jumper Modules that are needed for most radios.  If your radio is not shown, then please Contact Us and we'll help you figure out what you need.

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, carefully remove it from the black protective foam and 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, but firmly, press down evenly on the module until it is seated securely in the socket.  The module will usually snap into place. Be careful not to press on any jumper/header pins that might be mounted on the top of the jumper module. See the following picture of a fully inserted jumper module and note how the smaller diameter section of the pins is not visible:

• Special Jumpers - Some jumper modules have special jumpers that may need to be configured for your radio.  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 and also note the following:
  
  

  	PWR	This jumper is NEVER used with the SignaLink USB since this product is always powered by the USB port.  This jumper is there for users of our older SL-1 and SL-1+ models only.
  	SPKR	This jumper should be enabled only if Speaker Audio / RX Audio / AF Out is available on the radio's mic jack. If this signal isn’t available (check your radio manual!), then this jumper should NOT be enabled. Instead, you will need to connect the supplied audio cable as described in the “Connecting The Radio” section of the SignaLink manual.
  	SLMOD13K PTT Jumper	The configuration of this jumper is covered in detail on the cable document that ships with this SLCAB13K cable.  Please refer to this document for details on the use of this jumper.
  	G1 / G2	These jumpers apply to the SLMOD8RY module only and are detailed in the SLMOD8RY section 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 reported removing 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

• Are the plug & play jumper modules compatible with all SignaLink models?
• Do the plug & play jumper modules supply power for the older SL-1+?

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 older 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.

SLMODKX3 - 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.

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

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.
