Abstract:
1. A method for automatically determining a multi-switch type for a multi-switch attached to a receiver, the method comprising the steps of: generating a first control signal at a multi-switch connection port, the first control signal being designed to address a first port of a first type of multi-switch; determining if a first predetermined marker pattern is received within a first predetermined time limit after generating the first control signal, the first predetermined marker pattern having a first identification code; generating a second control signal at the multi-switch connection port, the second control signal being designed to address a second port of the first type of multi-switch; determining if a second predetermined marker pattern is received within a second predetermined time limit after generating the second control signal, the second predetermined marker pattern having a second identification code; determining if the first identification code is equal to the second identification code; and determining that the multi-switch type is the first type of multi-switch if the first identification code is not equal to the second identification code.
