I have 3 SMS units running at different installations. The firmwares are 3,01 (one) and 3,04 (2) I want to update the one with 3.01 to 3.04 through my PAB connection. (I know how to do that) However I can only find firmware 3,03 at your website. Where can I find 3,04 and is it worth to update the fimware?

Sincerely Lasse
