Am having problem linking Phidget based TC to roastmaster.  Using windows based laptop, have connected serial port, and am able to read temps for single TC in Phidget control panel.  Web service is on automatic.  After entering serial number, and port in probe section of roastmaster, status shows as 'unlinked'.  Have shut systems down and restarted, per another post on this site, no luck.  Am unable to unblock Windows firewall to port 5001, per another post on this site, as not sure how to do it.  Any ideas on what to try to have this link up?  Anxious to play with new system, so any help appreciated (with detail, as I am not software engineer….).  Thanks in advance!
