3.3 Indicators
On the rear panel of the HPQ2-IP control unit there are six LED indicators, their
functions are described below.
Filament Indicators
An indicator, Fil1 or Fil2 is lit to show the currently active filament.

The indicator is lit when the SEM detector is active. This is not implemented on the
HPQ2-IP as there is no SEM detector fitted.

active communications with the HPQ2-IP, this indicator will pulse at approximately
2Hz, depending on the RGA software version used.

booting, or when in FTP mode, otherwise it is off.
