Hi.  
I wanted to upgrade a Digi Connect ES 8 SB to the latest Firmware version. The support site showed 2 files: a POST and a EOS file. So I guessed I also had to update the POST.  
The Digi Connect had POST version 1.1.5 (release\_82001971\_B1) and after the POSt upgrade it had version 1.1.3 (release\_82001971\_A). So I unintentionally downgrade the POST.  
The firmware upgrade went flawlessly from 2.24 to 2.26.1.  
How can I obtain POST version 1.1.5 now?

Thanks!

The fact that you were able to upgrade to the latest would indicate that it is irrelevant to the version of POST you are running.

With the above said, if you still want to upgrade to the latest POST please open a case with tech support. To do so just send an email to:
