I bought a new RUT955 a few weeks ago, upgraded FW to 7.02.1, had a serial to IP server going extracting some data from a PLC thru Zerotier VPN. Life was good. Then two weeks later, my web application stopped updating, upon investigation i found that the RS232 and RS485 menus disappeared from the services tab (and yes i was in advanced mode). I was properly confused. Not only that, in the UI under status - system - device, information was missing. see pics
Tried rebooting, nada. Tried FW upgrade to 7.02.3, verification error. Oh, and this thing is sitting 700km away from me. So i dont have physical access to it. Any suggestions? Factory fault? There are another 12 of them which i have commissioned in exactly the same manner and they are just doing just fine, for now. Help!
