The board has a field of 9 jumpers designated “ID” labelled 1-8 and MB. Jumper MB is reserved for future purposes, leaving 8 for addressing. The address is the numeric address used by Xwire to select a particular board on the Xwire bus. Every board connected to an Xwire system (be it using the Xwire connections or RS485), must have a unique address. The jumpers are in a binary format meaning each jumper has a unique value. Any address value from 0 to 253 is possible by adding links to the jumper connector. Every link added adds that jumper’s value to the final total.
