Well, you get what you pay for. Much less hassle, only one cable to

control clock, data and control information - up to several 100 meters etc.
Think of the setup and maintenance costs. This is the plug-in-and-forget

solution.

The RME cards are easy to set up: Just connect the internal sync port

using the cable that came with the cards and select "Internal" as sync

source on the slave card.
