Note that with versions of PME that do not have native CPE330 support, only CPU320
projects can be stored to CPE330s that are in Normal (CPU320) compatibility mode
and only CRU320 projects can be stored to CPE330s that are in CRU320 compatibility
mode. Users of a CPE330 with PME version 8.60 SIM 8 or later do not need to change
this compatibility setting if the project is converted to a CPE330 application. By
factory default, the CPE330 is set to Normal (CPU320) compatibility mode.
Migration of CPU315 applications to the CPE330 is possible with no upgrade to PME
by converting them to a CPU320 application and storing the project to the CPE330.
Note that CPE330s with firmware versions 8.45 through 8.60 support compatibility
with the CPU320 and CPU315 only. The compatibility setting using the RDSD buttons
is not supported for these firmware versions. Beginning with firmware version 8.70,
CPE330s support compatibility with the CPU320, CPU315, and CRU320 using the
RDSD buttons to set the compatibility mode.
The compatibility setting may be viewed at any time using the CPE330's firmware
update web page. When the compatibility setting is Normal (CPU320), the catalog
number is listed as "IC695CPE330". When the compatibility setting is CRU320
compatibility mode, the catalog number is listed as "IC695CPE330 CRU320
Compatibility Mode".
