We discovered a new cataclysmic star and carried out prolonged and precise photometric observations, as well as medium- resolution spectral observations. Modelling these data allowed us to determine the physical parameters and to establish its peculiarities. To obtain a light curve solution we used model whose emission sources are a white dwarf surrounded by an accretion disk with a hot spot, a gaseous stream near the disk's lateral side, and a secondary star filling its Roche lobe. The obtained physical parameters are compared with those of other SW Sex-subtype stars. Description: The spectral observations of 2MASS J22560844+5954299 were carried by the 2m RCC telescope equipped with the focal reducer FoReRo 2 and grism with 720-lines/mm. The resolution of the spectra is 2pix or 2.7Å; and they cover the range 5600-7000Å. Most of the spectra have a S/N of 16-22 excluding those at the eclipse where the S/N value is around 7. The spectra were reduced using IRAF packages for bias subtraction, flat-fielding, cosmic ray removal, and one-dimensional spectrum extraction.
