Master and extension connection order. Connect each extension instrument to the master instrument sequentially from left to
right (Extension B, C, and then D).
NOTE. Connect the extensions to the master in a star pattern, do not daisy chain the instruments.
If powering off a multi-instrument system, power off the master first.
