Re: [LAD] Is it possible to use two RME cards in sync?

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.
