* Although pins 1–3 and 4–6 of header JP1 are shown “jumpered” for the termination and
bias resistors not connected, pins 3 and 4 are not actually connected to anything, and this
configuration is a “parking” configuration for the jumpers so that they will be readily
available should you need to enable the termination and bias resistors in the future.
