Each variant of the breakout connectors features two solder jumpers which can be used to enable the built in termination. > [!info] > The CAN FD Adapter must be plugged-in for the termination to work. Unplugged breakout connectors/adapters will not provide any termination to the network. # Tools Required - Soldering iron. - Soldering wire. # Steps 1. Ensure the breakout board is entirely disconnected from both the CAN Bus network and CAN FD Adapter. 2. Turn on the soldering iron and wait for it to reach operating temperature. 3. Apply solder to the tip of the iron. 4. Place the soldering iron tip across one of the solder pad pairs labeled "TERM." on the breakout board. 5. Once the solder has wicked to the pads, remove the soldering iron and observe that a connection has been made. 6. Repeat steps 3 and 4 for the other solder pad pair to complete the termination. If an excessive amount of flux is left on the solder joints, isopropyl alcohol and a cotton tipped swab can be used to clean the joint. # Removing Termination If you wish to remove the termination after soldering the jumpers, the solder must be removed completely using solder wick to ensure there is no connection being made. # Example The below picture illustrates a breakout board before (left) and after (right) the termination connection has been made. ![[can-db9-breakout-termination.webp]]
