Patent ID: 7341193

Claim:
A system comprising: a device loop controller; one or more device loops configured to communicate with device loop controller, wherein each of said one or more device loops includes a plurality of devices, and wherein each of said one or more device loops defines an operatively connected state in which said one or more device loops communicate with said device loop controller, and an operatively disconnected state in which said plurality devices in said one or more device loops communicate with each other; a hand-held device having a display, said hand-held device configured to: operatively connect to said one or more device loops when said one or more device loops are in said operatively disconnected state; and test said one or more device loops when said one or more device loops are in said operatively disconnected state, wherein said one or more device loops are operatively connected to said device loop controller after being tested by said hand-held device, wherein said hand-held device is operatively connected to said one or more device loops to determine whether devices in said one or more device loops are communicating properly.
