7.5 CPM-4 replaces CPM-2
The CPM-4 was created to add new features (including on-board networking capability) and
deal with component obsolescence.
Main compatibility notes:
• A CPM-4 may be installed in any chassis without any special considerations.
• A CPM-2 may be installed in a newer chassis (shipped with CPM-4 and/or DSP-2
modules as long as the CPM-2 software is upgraded to revision 1.18 or higher. Consult
Raytheon for upgrade information. Operation with the CPM-2 in a newer version
ACU-1000 will support all features that were supported with the CPM-2 in a legacy
chassis; however, some of the new features cannot be supported.
• The CPM-2 is configured by dipswitches on the module rather than via a front panel
Ethernet port (as is the CPM-4). The CPM-2 dipswitch settings are explained below.

7.5.1 CPM-2 Switch Settings
The dipswitches on the CPM-2 module configure the chassis for proper operation in its
customer-specific application. There are three eight-position dipswitches on this module. SW1
sets remote control parameters, configures the chassis for use in an expanded system, and
includes a dipswitch used only in the factory for testing purposes. All of the eight dipswitches
of SW2 are reserved for future use and should be kept OFF except for SW2-1 which shall
remain ON to enable *36 SAVE command. The dipswitches are only read by the ACU-1000 at
unit power-up, so to change unit configuration, shut main power off, pull out the CPM-2
module, change dipswitch settings as required, reinstall the module and turn main power back
on. If using the CPM-2 on an extender card, it will still be necessary to turn power off/on in
order to get the unit to read the switches and change configuration accordingly. In the tables
below, the default settings are marked with an asterisk.
