Abstract: A laboratory sample distribution system comprising sample container carriers, a central controller having a network interface, and transport modules is presented. Each transport module comprises a transport surface, wherein the transport surfaces form a transport plane, a controllable driver arranged below the transport surface and configured to move sample container carriers on the transport surface, and a control unit for controlling the driver. The control unit comprises a network interface. The central controller and the control units of the transport modules are connected by their corresponding network interfaces. Each control unit comprises first and second addressing terminals. The addressing terminals are connected sequentially in a daisy chain topology. The first addressing terminal is the first control unit in the sequence and is connected to a first reference potential and the second addressing terminal is the last control unit in the sequence and is connected to a second reference potential.

Abstract: A method to correct signal light intensities measured by a detector of a detection unit in a laboratory instrument is presented. The detection unit comprises a light source, a sample plane comprising a sample holder configured to hold at least one sample vessel comprising a test sample to be illuminated, a reference light sensor, and the detector. Based on a basic light intensity of a newly manufactured light source and an initial light intensity measured by the reference light sensor the sensitivity of the reference light sensor can be determined. And signal light intensities measured by the detector can be corrected based on the determined sensitivity and subsequently measured reference light intensities of the reference light sensor in order to generate comparable test results.
