	Due to Joint Institute for Nuclear Research participation in ILC collaboration, e-linac accelerator test-bench is being created in Laboratory of high energy physics of JINR. The bench is designed for several goals: accelerating structures and diagnostics testing, photoinjector prototype creation and investigation, radiation resistance studies of different materials etc. In addition, several proposals of FEL creation on the basis of the e-linac exist. Current setup, results of the test-bench control systems evolution since 2009 and future plans are presented. The most important updates include radiation control system calibration, verification and installation and an upgrade of the video control system.

	Control system for RF source of 30 MeV, 3 kW RF Linac for neutron generation is being developed. The system consists of two 15 MeV linac structures, each powered independently with klystron rated for 7.5 MW(pk)/7.5 kW(avg). Two klystron modulators of 160kV, 110A, 7usec and 250Hz feed pulsed power into the klystron, which produces RF power at 2856 MHz. The klystrons will be driven by low power RF driver amplifiers programmed for matching phase, frequency and power into the linac. Both the driver amplifiers are controlled through RS-232 Protocol. The HV pulsing and RF drive for the klystron has been interlocked with water flow, arc detector, SF6 gas pressure etc. The control system is designed using Real time embedded controller, where pulses for synchronization are being generated in FPGA. Most of the power supplies like electromagnet, HVDC, etc. are on RS-232 protocol. These power supplies are controlled via suitable RS-232 to Ethernet converter. State machine topology is being used to design the logic. The database for logging data is developed in SQL. This paper describes the details of the software implementation and hardware used to realize the control of the RF power source.
