9.5.1 Intensifier Control
The luminous gain of Intensifier tube is controlled in a log-linear fashion via the serial port (IGN
parameter). The intensifier may also be gated to provide duty-cycle control of its "on" time--the
gating is internally derived but controlled via the serial port (IPO and IPD parameters) in several
different modes (set by the IMD parameter).
