It is used as a part of computer-automated test system and designed to give the drive codes to relay command blocks of orbital vehicles computer-aided testing and controlling system, accepts and transforms information about the unit under test condition. Control is maintained with KVV-S controller on PC commands. It’s settled into "Evromechanika " block case.
