New version of progressive-scan digital television camera on the basis of Fast Ethernet interface was developed. Camera is intended for the measurement of position and parameters of particle beams in the VEPP-4 and VEPP-2000 storage rings by the using of synchrotron radiation. In the report the structure, key parameters and some features of the new camera are described. The assumed directions of further camera modification and the corresponding schemes of its application in the physical experiment are discussed too.

VEPP-4M collider has been worked since 80th. Growing expenses for maintenance of obsolete electronics make us to conduct a number of modernization programs. The problem is in keeping of facility in operating state during modernization process. To achieve it we have decided to implement new electronics on modern components but pin-to-pin and bit-to-bit compatible with obsolete prototypes. It allows keeping intact software and replacing old equipment by hidden way. There were described two of these new devices. They are intelligent multichannel DACs for controlled power supplies. VEPP-4M includes approximately 300 power supplies for bending magnets and steering coils controlled by these devices. One device provides 16 channel of DAC with resolution 16 bit and accuracy better than 0,01%. The second device is intended for precise power supplies for bending magnets and provides resolution 20 bits and accuracy up to 0,001%. The paper covers different aspects of design and resolved problems and shows achieved results.
