For purposes of lag reduction, if the import bus has not imported something recently, it goes into a sort of "sleep mode" where it operates slowly, and wakes up and accelerates to full speed (4 operations per second) when it successfully imports something. They are [cable subparts](../ae2-mechanics/cable-subparts.md). ## Filtering By default the bus will import anything it has access to. Items inserted into its filter slots will act as a whitelist, only allowing those specific items to be imported. Items and fluids can be dragged into the slots from JEI/REI even if you don't actually have any of that item. Right-click with a fluid container (like a bucket or fluid tank) to set that fluid as a filter instead of the bucket or tank item. ## Upgrades The import bus supports the following [upgrades](upgrade_cards.md): * increases the amount of filter slots * increases the amount of stuff moved per operation * lets the bus filter by damage level and/or ignore item NBT * switches the filter from a whitelist to a blacklist * adds redstone control, allowing active on high signal, low signal, or once per pulse ## Speeds | Acceleration Cards | Items Moved per Operation | |:-------------------|:--------------------------| | 0 | 1 | | 1 | 8 | | 2 | 32 | | 3 | 64 | | 4 | 96 | ## Recipe
