Hi Ozzy,
No, for your PreMate it’s 201.62, as can be seen on the Support page of the website. (For my HDP-5 it is 201.61; I did that update a while back and it went very smoothly). A pdf providing instructions for performing the update can also be found on the Support page.
If you need the login information to download the firmware file you can contact Alan Langford at DEQX, or submit an inquiry via the website.
Best regards,
-- Al
