3.4.2 Hardware and firmware versions for the PCD3.Mxxx0
The firmware versions for the PCD3.Mxxx0 are generally upwardly compatible in
terms of hardware, so old CPUs can be fitted with new firmware, in order to take
advantage of new functions. This feature is highly valued, and we will try to retain it
for as long as possible; however, we cannot guarantee this.
The firmware for the PCD3.Mxxx0 is stored in a Flash EPROM, soldered to the
motherboard. A firmware update can be applied by downloading a new version with
the PG5. The procedure is as follows:
Go to www.sbc-support and download the latest firmware version
Establish a connection between PG5 and the CPU, as for a download of an
application (depending on the facilities available, serially via PGU cable, modem
1)
,
USB, Ethernet)
Open the Online Configurator and go offline
From the Tools menu, select “Update Firmware”, then use the Browse function to
select a path to the file for the new firmware version. Ensure that only one file is
selected for downloading.
Start the download
After the download, the power supply to the PCD must not be interrupted for 2
minutes (CPLD programming sequence). Otherwise, the CPU may be blocked in
such a way that it needs to be returned to the factory
While the Run/Halt LED flashes slowly, the Download is not finished. Only when
the LED flashes fast programing has finished.
1) A modem connection is not always reliable. A modem may become blocked in such a way that remote access is
no longer possible. In such cases, an on-site visit will be necessary. Other connection options are preferable
