✐
NOTE: When applying power to pumps in a daisy chain, apply power to the last group in the chain first
and work backwards.
✐
NOTE: When removing power, be aware that power removed from a stand-alone unit will cause power to
be removed from all RS-485 powered units deriving power from that stand-alone unit.
✐
NOTE: Power may be removed from any group of pumps, except the first group, without affecting
communications “downstream”
✐
NOTE: Each pump in the daisy-chain must have a unique address. The first pump must be set to address 00.
✐
NOTE: When daisy-chaining with RS-485, at a minimum, every 4th pump in the daisy-chain must be
self-powered (i.e. another stand-alone unit). This can be affected by force selection.

NOTE: If a larger chain of pumps with mixed software versions is desired, pumps with software
versions 1.0.6 or lower can be returned to manufacturer for a hardware update.
