  • Patent number: 5568046
    Abstract: An inactive state termination tester for determining the number of terminators connected to a bus when the bus is inactive. The termination tester monitors the bus for determining when it is inactive. During the periods of bus inactivity, the termination tester senses the bus to determine the number of terminators connected to the bus. The termination tester then displays how many terminators were detected and/or generates a signal to either enable or disable, respectively, a controllable bus terminator depending on if there are not enough or too many terminators determined to be connected to the bus. Furthermore, the termination tester maintains the controllable bus terminator in the proper enable or disabled mode whenever bus activity resumes.
