We are developing a 2K × 2K format array control system (UTIRAC: University of Tokyo InfraRed Array Control system) for "WINERED", which is a new high-resolution (Rmax = 100, 000) near-infrared (0.9-1.35 μm) spectrograph being built at the Institute of Astronomy, University of Tokyo. UTIRAC has the following two characteristics: (1) applicable to various infrared array (with Amp-ADC integrated boards which enables easy increase/decrease of the number of input channels) and (2) based on the MESSIA5 system (for clock generation and frame acquisition) developed by National Astronomical Observatory of Japan. The goals of UTIRAC are low readout noise (< 10 e-) and readout speed of 200 kHz/pix (for the Raytheon VIRGO array). Working tests of each board and integration test with MESSIA5 system have been completed. As a next step, we are going to test VIRGO MUX for operation 4 with outputs and to evaluate readout noise. In the near future, we will increase the number of input channels on a single Amp-AD board from one to four for the operation of arrays with 16 outputs.
