sorry for the delay.
PBUS is a protocol that Carbonite supports for sending commands to devices -- those that don't support AMP either support PBUS or are connected to a Lance TDC-100 or a DNF Controlls device that they use the PBUS registers to link to Clips and Transport Commands.
The Roll PBUS allows us to invoke the same elements as the other items that we support in this manner. That way if we recall a Memory to PGM and that is enabled we will make sure to send PBUS Trigger command for the devices that are going to air in that Memory.
