Can you connect with CX-Programmer or Syswin? If yes you can see the error log there. It would help you, or help people here to help you.

Sounds like you killed it...

DId you try both ports, mini-peripheral and the DB9?

Dipswitch 5 to ON will set the default comms on both ports (after a power cycle) to 7,e,2 @ 9600.
