Ad2437 Sio0 Routing ( Jp6); Ad2437 Sio1 Routing ( Jp9); Adau1452 Clk Select ( Jp38); Usbi Spi Chip Select ( Jp42) - Analog Devices EVAL-AD2437A1MZ Manual

Jumpers
The purpose of the jumper is to set whether the board is a Main Node or Sub Node. If Main Node is selected, the
LTC4368 will close once appropriate voltage levels are detected. If Sub Node is selected, the LTC4368 will only
close if woken up by an upstream Main Node or Sub Node.
