560 Ohm Resistor (405298308)
Should be installed:
When using a single RPM module
or
When daisy-chaining RPM modules (as shown), the resistor
should only be installed in the last module in the chain.
Up to 95 RPM modules can be daisy-chained on a single bus as shown, provided that
the bus length, from the controller to the last RPM in the chain, is 100 meters or less. For
bus lengths between 100 meters and 300 meters (maximum bus length), the number of
RPMs on that bus must be reduced. See the RPM product manual (167-790-063).
