Remote-control Signals Setting Mode
(Note 1) When set to EI-03, behavior of remote-control signals is the same as ULVAC Turbo Molecular
Pump power supply "EI-xx03", "EI-Dxx03" and "EI-R04" series.
(Note 2) When set to SEMI E74, behavior of remote-control signals conform to SEMI E74 standard
"Specification for vacuum Pump Interface-Turbo Molecular Pumps".
Refer to the same standard about the shape of connectors and the pin configuration.
