Cascading Multiple Digi RPM Units
The Digi RPM power controllers can be cascaded when used with the Digi
Passport unit.
The DIP switches on the front panel of the Digi RPM allow configuring
unique identities (ID) to the Digi RPMs so they can be identified. In a
cascaded environment each unit has to be configured to a unique ID.
To cascade the Digi RPM units, connect a serial port of the Digi Passport
unit to the Console Port of the first Digi RPM unit using a straight-thru
cable. Connect the “Cascade” Port of the first Digi RPM unit to the
“Console” Port of the second.
Here is an example of two cascaded Digi RPM units connected to a Digi
Passport unit. Note that the ID for the first unit is set to 0 and for the second
unit it is set to 1.
