The description of "linking" 2 LE systems (or HD systems for that matter) is a bit misleading. They're not really linked, one is slaved to the other via positional and speed references. Essentially, one machine is set to generate MIDI Timecode out of one of the MIDI outputs (Setup>Session, Generate MTC to Port), the other is set to receive MTC thru one of its MIDI inputs (setup>peripherals>synchronization). The machine sending MTC is considered the MASTER, the one receiving MTC is considered the SLAVE.

Then an RCA cable is connected from the master to the slave's s/pdif connection. The slave's clock reference is set to s/pdif.

Now you have a positional reference via MTC and a speed (clock) reference via s/pdif.

Put the slave machine "online" (turn on the little clock'ish button on the far left of the transport window). When you press play on the master, the MTC should roll and so long as the slave's start time is set correctly (also in setup>session), the slave machine should start rolling.

This is really no different than synchronizing 2 or more tape machines. You simply have multiple machines playing in sync by virtue of the positional and speed reference.

Maybe that helps, maybe not. Good luck.
