Feeder/WOW Logic Board (DM475). The feeder/WOW logic board is lo-
cated in the feeder/WOW module of the DM475 and adds WOW machine
motion control (MMC) capability to the existing feeder logic board functional-
ity. The new board is attached to the back of the WOW unit. The feeder/WOW
logic board connects directly to the 6C00 main logic board via three cables.
Feeder/WOW Junction PCB (DM475). The feeder/WOW junction board
is located in the feeder/WOW module of the DM475 and is the connection
point for the WOW width sensors, WOW transport motor and servo, WOW
