Korea Superconducting Tokamak Advanced Research (KSTAR) will be operated in the 6nd campaign in 2013 after achievement of first plasma in 2008. Many diagnostic devices have been installed for measuring the various plasma properties in the KSTAR tokamak during the campaigns. From the first campaign, a data acquisition system of Electron Cyclotron Emission (ECE) Heterodyne Radiometer (HR) has been operated to measure the radial profile of electron temperature. The DAQ system at the beginning was developed with a VME-form factor digitizer in Linux OS platform. However, this configuration had some limitations that it could not acquire over 100,000 samples per second due to its unstable operation during the campaigns. In order to overcome these weak points, a new ECE HR DAQ system is under development with a cPCI-form factor in Linux OS platform and the main control application will be developed based on EPICS framework like other control systems installed in KSTAR. Besides solving the described problems main advantages of the new ECE HR DAQ system are capabilities of calculating plasma electron temperature during plasma shot and displaying it in run-time.
