<p>The present invention relates to a monitoring system (100, 200, 300, 400) comprising a first (130, 230, 330, 430) and a second (110, 210, 310, 410) portion. The first portion comprises a controller (132, 232, 332, 432) for providing a set of codes. The first portion is configured to connect said system to a common data bus (170, 270, 370, 470). The first portion (130, 230, 330, 430) is configured to provide a synchronisation signal to said second portion (110, 210, 310, 410) when the two portions are in a predetermined position. The second portion comprises a controller for replaying a code sequence to said first portion and said first portion being further configured to output said code sequence from said second portion for verification by a verification entity.</p> |
