Zusammenfassung:The NA62 experiment at CERN, aiming to start data taking in 2011, intends to measure the branching ratio of extremely rare kaon decays. The existing Liquid Krypton (LKr) calorimeter of the NA48 experiment will play an essential role in the new experiment. For this reason a program for the consolidation of the LKr read-out system was launched in 2006. The first part of the program consists of updating the existing data acquisition system to a modern more reliable technology using Gigabit Ethernet and PC-farm. In the second stage the readout event rate has to be increased from 13 kHz to 1 MHz. Methods to do this, while keeping much of the existing analog system, are discussed.
