Attach an ME Interface to your ME Network, making sure it has proper channels. Place your LP Provider Pipe against the Interface. Place your LP Orderer Pipe, then your LP Supplier Pipe. Attach a chest to the end of the Supplier Pipe. Try to order something from your system using the Orderer Pipe. If it doesn't work, swap the Provider Pipe and the Supplier Pipe (I never remember which is which until I have them in my hands).
Once you can order something to the chest, right-click (maybe shift r-click) the Remote Orderer on the Orderer Pipe to link them. Replace the chest with an EnderChest. Test your system.
