The upgrade for the ATLAS detector will undergo different phases towards HL-LHC. The first upgrade for the Pixel Detector will consist of the construction of a new pixel layer which will be installed during the long shutdown of the LHC machine in 2013/14 (Phase 0 Upgrade). The new detector, called Insertable B-Layer (IBL), will be inserted between the existing pixel detector and a new beam-pipe at a (smaller) radius of about 3.2 cm. The IBL requires the development of several new technologies to cope with the increase of radiation and pixel occupancy as well as to improve the physics performance of the existing pixel detector. 12 million pixels attached to new FE-I4 readout ASICs will require new off-detector electronics which is currently realized with two VME-based boards: a Back Of Crate module implementing optical I/O functionality and a Readout Driver module for data processing. An overview of the new IBL read-out system will be presented, focusing on the integration work performed at CERN with the production components. In order to finalize strategies for the system commissioning, data taking and calibration tests have been run. The outcome of these tests will also be discussed.
