'The logistics inventory system connector allows the player to connect two logistics system so they operate as one using a dimensional inventory such as an Ender Chest from the Ender Storage mod.' - logistic pipe wiki

'First you will need an aditional mod to use these pipes: enderstorage.

Basically these pipes just draw items from your system in a chest connected to them. So to set up let’s say two logistic systems at different locations you need a way to teleport items between these systems. Here the enderstorage mod comes in handy, because vanilla ender chest don’t connect to pipes they can’t be used. But the enderstorage chests work fine.

So how to set up such a system? Just connect one Inventory System Connector Pipe to your logistic system and put an enderstoragechest next to it. The same thing you do to the other logistic system. Then you have to put in the two frequency cards (be aware you have to craft them using a soldering station, cheated ones won’t work). The pipes shoult now turn from red to green. Now your systems are connected. To test it you may just request an item. It should be taken out of one system put in the enderchest and then extracted through the other enderchest and get to your request pipe.' - buildcraft mod forums
