7.6 DSP-2 Replaces DSP-1
The DSP-2 was created to add new features (including on-board networking capability and a
more powerful digital signal processor) and deal with component obsolescence.
Main compatibility notes:
• DSP-1 and DSP-2 modules may be used alongside each other in an ACU-1000 chassis.
• DSP-1 modules may be plugged into a newer version chassis (shipped with DSP-2
modules) with no special considerations.
• DSP-2 modules may be plugged into older version chassis (shipped with CPM-2
modules) as long the CPM-2 software revision is 1.18 or higher. Consult Raytheon for
CPM-2 software upgrade information.
