A process is provided for measuring a gas concentration with at least one thermal measuring element. By analysing the output of the detectors, the gas can be identified. At least one of the plurality of leads is internally routed and has a contact exposed interior to the ILB portion of the TAB structure. The control subsystem also instructs the Ethernet processing system to forward FC control frames to the control subsystem, and replaces first link state instructions in the Ethernet processing system software with second link state instructions to change Ethernet behavior to FC behavior.
