Change Termination on an SP12 Switch Panel

IMPORTANT!!! Caution shall be taken during this process due to a major risk of damaging the mechanical buttons on the panel. Damaged SP12 panels as a result of button removal will NOT be covered by warranty.

The settings of SP12 panel termination shall be decided and done before the buttons are attached. If you are expanding the network please follow the steps below.

-The button numbers follows from left to right and begins with 1 at the top left corner.
-The termination switch is placed under button 8 on the portrait model and under button 5 on the landscape model.
-Remove the button by following the guide for button removal, found on the ‘support’ page.Support
-On the PCB you will find a microswitch with the numbers 1 and 2. These are the two terminators you can set to ON or OFF (activate/deactivate).

With an expanded network above 6 meter one of the above shall be ON and the other termination placed at the other end of the NMEA2000 network. Alternatively you can set them both to OFF and have the two terminators placed separately in the NMEA2000 backbone.
