HRC Contingency Command Sequences

Set HRC-I Unique Defaults with CEA B

Description:

This command sequence sets the HRC instrument configuration default settings that are specific to using the HRC-I. High level pulse commands are used to select which detector is connected to the active pre-amps, HRC-S to CEA A (inactive) and HRC-I to CEA B (active). Then a series of serial digital commands are sent to set the defaults for hardware processing.

Cautions/Restrictions:

This command sequence assumes that the HRC power configuration has been set using the command sequence "Power Configure HRC to use CEA B" (or "Power Configure HRC to use CEA B with Redundant PowerBus") and that the HRC has been powered using the sequence "HRC Power Up on CEA B".

This sequence should not be executed until the HRC has been powered for at least 90 sec.
