Detecting tampering of an incoming cable to which a network interface unit is connected by testing for the reflected signal that is present when the signal being transmitted to the head end is not connected to a properly terminated coaxial cable. The first panel comprises a display surface. A special load-sensing belt module forms the clevis and holds electronic circuitry that takes the measurements made by the sensor, logs them in a memory element, and transmits them wirelessly to the belt monitoring system. For example, where the functionality comprises a programmatically callable function, the information created may include information specifying the function name, names of input and output parameters, data types of the parameters, etc.
