 > I have six SMT 24 targets.  I am trying to link the targets together with a router so I can select Master on one target and Slave on the other targets.  The Master target says "Number of connections: 0".  The Slave target says "Master not found".  I have tried it with 2 new routers and 1 switch.  I have tried every possible way and order to try to get them to talk to each other.  I have even reset all of the target back to Factory Default and re downloaded the purchased SMT Contents.  I had a professional IT guy try to get them to work and nothing gets the targets to link or "Talk to each other".  Please advise.  Thank you.
