✐
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: If a larger chain of pumps with mixed software versions is desired, pumps with software
versions 1.0.4 or lower can be returned to manufacturer for a hardware update.
RS-485 Dasiy Chain Connection Options:
If all pumps have software versions 2.0.0 or higher, 99 pumps in chain. •
If all pumps have software versions 1.0.4 or lower, 99 pumps in chain. •
If mix of pumps with software version 1.0.4 or lower and 2.0.0 or higher, maximum of 5 pumps in chain •
and 1 RS-485 adapter (catalog # 78-8339) required.
