ii. When the desired compatibility setting is displayed, press the RDSD UPLD button to save the setting and
allow the CPE330 to continue its normal startup procedures with the new setting. The setting is
maintained over a power cycle and firmware upgrade.
Note that with versions of PME that do not have native CPE330 support, only CPU320 projects can be
stored to a CPE330 that is in CPU320 compatibility mode. Similarly, only CRU320 projects can be stored
to a CPE330 that is in CRU320 compatibility mode.
Users of a CPE330 with PME versions 8.60 SIM8 or later do not need to change this compatibility setting.
PME versions 8.60 SIM8 or later allow for storing a CPU320 or CRU320 project without the need to change
this setting. By factory default, the CPE330 identifies as a CPU320.
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 (described above) 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 setting.
