  • 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. 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… RS232 Interface Control the NanoGen 1 with the HMI NanoGen 1
