VI. NanoGen 1 HMI The NanoGen 1 is controlled by a « Human-Machine Interface », developed by RLC, that can be installed on any PC or on a laptop. Control the NanoGen 1 with the HMI NanoGen 1 RS232 Interface The NanoGen 1 HMI controls : - The external HV Power Supply Output Voltage / ON / OFF - The PWM or BURST Output Pulses parameters Pulse Frequency / Pulse duration… Technical Presentation | RLC, CLERMONT-FERRAND 9 NanoGen 1 : Smart HV Pulses Generator (V2.1)

VII. Maximum Power Limitation (Update V2.1) For each curve below, the blue line represents the maximum power limitation. The safety area is under this line. Thanks to the new software V2.1, the user can not go beyond the maximum power limits.
