A controller interface device based suitcase tester

A computer software based suitcase tester emulator for testing traffic controllers is described. The software emulator utilises a controller interface device (CID) to communicate between the computer and the traffic controller under test, providing the ability to program the suitcase tester to model pulse and presence detectors and program their settings. The CID interface provides the ability to simultaneously test a large number of traffic controllers. The future applications using this emulator are explored.
